iSpring RCS5T 500 GPD Osmosis Water Filter System Review

iSpring RCS5T 500

If you have to manage or own a small commercial concern, ensuring the quality of the drinking water can easily become a bewildering decision due to all the products on the market. For a business owner, it is important to decide on a product that leaves the customer, as well as the company, satisfied.

To help you make the best decision for your specific environment, we have reviewed the iSpring RCS5T 500 GPD Reverse Osmosis Commercial Grade Tankless Water Filter to see if it will meet the demands of a small business.

iSpring RCS5T 500 Water Filter

iSpring has been in the water purification business for more than 10 years and developed the commercial-grade RCS5T as an affordable investment for small businesses (or even large families) that need constant, high quality water-on-demand for drinking and other applications.

iSpring designed this point-of-use filtration system not only to purify water, but also to ensure that it will handle the higher-pressure requirements of a commercial concern.

Who Is This Water Filter for?

The RCS5T has been designed for commercial use in small companies such as restaurants, coffee shops, small offices, and stores. It will meet the demands of small companies for whom a high-quality supply of water is of optimal importance.

Because this unit is tankless, there are no large storage problems to deal with. However, if you require storage you can always add a tank and storage pump which is sold separately.

Thanks to its built-in booster pump it will not only remove impurities, but also ensure that no matter how high the demand is, there will be a steady high-pressured supply of water without any fuss.

What’s Included?

Everything required to install the unit is included with delivery. This consists of:

  • High-capacity 5-micron 10" polypropylene sediment filter
  • Granular Activated Carbon (GAC) 5-micron 10" filter
  • Carbon Block (CTO) 5-micron 10" filter
  • 500 GPD patented dual-flow .0001 micron Reverse Osmosis Membrane
  • Polishing inline post carbon filter
  • Built-in booster pump
  • Lead-free, long-reach, luxury goose neck faucet.
  • Color-coded and food-grade tubing
  • Installation manual
  • All the accessories required for installation: filter housing wrenches, feed water valve, drain saddle and inserts

Overview of Features

Whereas normal filtration systems only use filters to purify water, those using reverse osmosis use different size filters as well as membrane to catch the tiniest particles in water. The pre-filters are there to ensure that substances such chlorine and sediments that can damage the reverse osmosis membrane are removed prior to the reverse osmosis process.

To save space in confined environments, the unit can easily be installed underneath a counter or sink with dimensions of 14"w x 11"d x 17.5"h and weighing 28lbs.

The iSpring RCS5T 500 is so-named because it processes 500 gallons of water per day, with a filtration ratio of 9ppm. The water-to-waste ratio is 1:1, which means less waste water than most other reverse osmosis products on the market, and therefore a lot more savings over long-term use.

This filtration system uses four canisters and a reverse osmosis film to filter almost all bacteria and impurities from tap water. Water is sent through each canister and while passing through each filter, tinier and tinier particles are trapped and removed.

The process starts when water passes through the first polypropylene sediment filter that is designed to trap different kinds of sediment such as rust, dirt, and silt.  This canister is see-through to make it easier to see if it is blocked and needs replacement.

The next cartridge has a 5-micron GAC (Granulated Activated Carbon) filter that traps chlorine particles as well as other impurities that cause cloudiness, in addition to other pollutants such as mineral oils and phenol.

The treated water then passes through a denser carbon block filter that will remove any residual color, smell, and taste as well as chloramines.

When the water reaches the fourth stage, it is pushed through a patented dual-flow reverse osmosis membrane by high pressure. This semi-permeable membrane has tiny holes (only 0.0001 microns wide) that removes arsenic, lead and other contaminators as well as biological matter.

In the last stage the water is sent through a final polishing filter that ensures that 98% of chemicals, pesticides, and other contaminants are removed.

By the time the water reaches the faucet it is ready to be safely used and consumed. The built-in booster pump ensures that output water pressure is maintained around 10-15 psi. The faucet that comes with the filtration unit has a long-reach goose neck to facilitate easy handling and cleaning.

Unfortunately, this unit does not supply water to any other points, which means that you will not be able to connect kitchen appliances such as coffee machines and ice makers without after-market modifications.


The instruction manual supplies detailed instructions on how to install the system. Installation of the unit will take time but should be manageable for someone who has even just a bit of experience in plumbing.  You can always hire a plumber too to help with the installation.


The iSpring RCS5T can filter 500 gallons per day, but if you would like to explore other filtration units, you might consider the Flexeon 500 GPD Titan Commercial Reverse Osmosis System.

This unit produces 500 gallons per day using big blue sediment and carbon pre-filters and two TFC HF1 membranes. It can distribute purified water to more than one location, so it can be used for different appliances in a kitchen environment or anywhere in your home or office.

The Flexeon’s high quality Fluid-O-Tech pump delivers the water to the membrane under ideal pressure. This system also has pressure gauges that can be monitored if you suspect that your water pressure has decreased and need to know if you have to replace the filters.


The iSpring RCS5T is a well-designed high-quality water filtration system that needs minimal maintenance to keep it running quietly and supplying good quality drinking water for small businesses.

APEC Portable Countertop Reverse Osmosis Water Filter Review

APEC Portable Countertop Reverse Osmosis Water Filter Review

Are you looking to improve the taste of tap water in your home? Or perhaps you are concerned about ingesting impurities that can be bad for your health? Either way, the quality of your tap water could probably use some improvement.

So, what is the solution? It can be tough to choose one when there are so many products available on the market. Today, we're here to tell you about the APEC RO-CTOP, an easy to use and effective water filter that is suited for most households.

APEC Portable Countertop Reverse Osmosis Review

The APEC RO-CTOP is a reverse osmosis water filter system. Reverse osmosis (RO) filters are popular because they are usually affordable, safe to use, and able to remove most pollutants from the water while improving its taste. Not surprisingly, this is exactly what this filter does.

It is a portable water filter system, which means you can carry it with you wherever you go, and it fits most standard faucets, with little installation required. The tap water goes in through a tube, passes through the filter, and comes out cleaner and fresher.

People have been using the RO-CTOP since at least 2005, and it is quite popular due to its small size and ease of use. However, the reverse osmosis filter does tend to make the water slightly acidic, although this is hardly noticeable. To address this issue, APEC released the RO-CTOP-PH, which adds calcium carbonate to the filtrated water to safely increase its pH.

Both the RO-CTOP and RO-CTOP-PH can be purchased with a handy aluminum carrying case. The versions with the included case are called RO-CTOP-C and RO-CTOP-PHC, respectively.

Who Is This Water Filter For?

Thanks to its portability (it only weighs 11 pounds), the RO-CTOP is the ideal choice if you travel a lot and like to drink clean water wherever you go.

Its small size (14x6.5x6 inches) also makes it a good option for small apartments or RV's, where it can be complicated to fit larger systems. If you are staying at a rental home, you should also buy one of these, because you may not want to install a more permanent solution.

You would think that such a small piece of equipment would not be enough for everyday use, but it can output an impressive 90 gallons of water per day (at 60 psi pressure). Just remember, the system cannot handle hot water (100º F is the limit).

However, it does not have a storage tank, so you have to store the water beforehand if you need it in short order. So if you require large amounts of clean water on demand, the RO-CTOP is probably not for you.

What’s Included?

The unboxing of the RO-CTOP is quite easy and simple. It includes all the essentials to get the system up and running, as long as you have a standard faucet on your countertop.

Thanks to the included adapters, you can connect the faucet adapter to any male or female 13/16'' or 15/16'' faucet.

Summing up, here are the contents of the package:

  • Installation instruction & owner's manual
  • RO-CTOP equipment, complete with 4 filtration stages
  • Faucet adapter with tubing
  • 13/16'' male thread valve adapter
  • 15/16'' male thread valve adapter
  • Rubber grommet

Unboxing Video

Overview of Features

So let's take a look at what the RO-CTOP is capable of. As we've seen, it is a really handy piece of equipment that you can carry with you anywhere and just leave on a countertop, since it won't take up much space. The numbers do not lie: it weighs only 11 pounds and measures 14x6.5x6 inches.

The system features 4 filtration stages, each one in charge of a different task. Stage 1 is responsible for removing dust, rust, and particles from the water. Stage 2 gets rid of any unwanted odors and colors, along with chlorine.

Stage 3 is the reverse osmosis membrane, where most of the magic happens. It can remove up to 99 percent of total dissolved solids (TDS) contained in the water, along with nasty contaminants like arsenic, chromium, fluoride, lead, radium, selenium, and even bacteria and viruses.

Finally, a stage 4 carbon filter will remove any residual tastes from the water, making it suitable for consumption.

The capacity of the RO-CTOP is impressive. It outputs 90 gallons of water per day at 60 psi or 75 gallons at 50 psi. These numbers were measured at 77º F. It can withstand input water pressures from 35 to 90 psi and temperatures ranging from 40º F to 100º F.

The only missing feature from this filter is a water storage tank, but if you think about it, this would defeat the purpose of portability.

How to Use It

Installation of the RO-CTOP is a breeze, so you probably won't need to call a specialist. There is no need to fiddle around with pipes or large tools, as the filter simply connects to the end of your kitchen faucet. Just keep in mind that it is not compatible with pull-out, sprayer, or special-size designer faucets.

If there is an aerator currently attached to your kitchen faucet, remove it first. Then, you just have to connect the faucet adapter to the kitchen faucet. If the size does not match, you can use one of the provided adapters.

When this is done, remove the red cap from the end of the output tube and you are ready to go! Check out this video if you have any doubts. The instruction manual provided by APEC Water also gives a good description.

As far as maintenance goes, you do need to swap the filter cartridges once in a while. APEC recommends changing stages 1 and 2 of the system every 6 months or 600-800 gallons of water. Stages 3 and 4 require less maintenance since they only need to be replaced every 2 to 3 years.


Because it is a reverse osmosis water filter system, the RO-CTOP tends to slightly acidify the water it filtrates. While the pH change may not be noticeable, it is not ideal, either.

If you also feel this way, you can opt for the RO-CTOP-PH instead. The difference between this system and its older brother is in the 4th filtration stage: the RO-CTOP-PH adds purified calcium carbonate to the water, in order to safely increase its alkalinity.

Alternatively, you may be interested in a less portable solution that provides some water storage capacity to simplify the logistics. The APEC RO-90 is a great alternative: it has a 4-gallon tank, with an additional 14 gallons as an option. This impressive system even has a WQA gold seal certification, which is a symbol of quality, safety, and reliability.


If you are looking for a good water filtration system, especially one that you can carry with you, then the APEC RO-CTOP is definitely a product to consider. It can filter up to 90 gallons of water per day and remove some nasty pollutants from it, such as arsenic, cadmium or lead.

It uses a reverse osmosis system, which is one of the safest and most affordable methods of filtration available. You'll notice a change for the better in the taste and odor of your water.

iSpring RCC1UP 6-Stage Maximum Performance Under-Sink Reverse Osmosis Drinking Water Filtration System Review

The iSpring RCC1UP water filter is great for well water

Do you think about your diet often? Do you worry about what you are eating and make sure you get the necessary amount of recommended nutrients every day? What about contaminating agents or foul substances that may be in your food if its quality is not tightly controlled?

If you worry about these issues, maybe you ought to think about the water you are drinking, too. Some studies have shown that, over the last decade, about one-fifth of the United States population was exposed to water from sources that violated certain key provisions of the Safe Drinking Water Act.

So, how do you drink tap water at your home safely? Well, one of the best ways is to install a reverse osmosis water filter system under your kitchen sink. We recommend a reverse osmosis filter because they are relatively inexpensive and quite effective in the disposal of contaminants. Today, we're taking a look at the iSpring RCC1UP.

iSpring RCC1UP 6-Stage Review

This filtration system, like most reverse osmosis filters, is meant to filtrate the water that comes out of your kitchen faucet, instead of filtrating water for the whole house. Its purpose is to make the water perfectly safe for human consumption.

Due to their size, this type of systems is too big to have on top of your counter but thankfully small enough to fit under the kitchen sink. Some have a storage tank to always keep a reserve of clean water, and that is the case of the filter we're reviewing.

Since its release, the iSpring RCC1UP 6-Stage has undergone quite a few upgrades, which shows the company cares about their customers. A new faucet, RO membrane, feed water adapter and automatic shut-off valve were introduced; the booster pump, storage tank valve, and post carbon filter were upgraded; a flow sensor switch and water flood alarm were added to the UV filter; and the user manual was updated.

Who Is This Water Filter For?

Obviously, this filter is indicated to everyone who wants to improve the quality of their tap water and make it safe for consumption. But in this case, you'll have to be willing to spend a bit more than the price of a basic reverse osmosis filter, but for good reason: the system includes useful features like a storage tank, a booster pump to increase the water pressure, and 6 stages of filtration, as opposed to the usual 5 stages.

Consequently, this filter is not for those who are tight on budget or don't require advanced features like the booster pump. This could be the case if your house has good water pressure, to begin with.

What’s Included?

The packaging of this filter seems carefully thought out, as it contains pretty much everything you would expect with this type of product, including some of the tools necessary for installation. It does not include absolutely everything you need for the installation, as there are some household tools you have to acquire, if you’re not already in your toolbox.

The package contents are:

  • User manual
  • 3 pre-filters for filtration stages 1, 2, and 3
  • 3 filters for filtration stages 4, 5, and 6
  • Brushed nickel faucet
  • 3.2-gallon water storage tank
  • Booster pump (pre-installed)
  • 1/4-inch tubing
  • Automatic shut-off valve
  • Check valve

Installation tools and parts:

  • Filter housing wrench
  • Membrane wrench
  • Drain saddle
  • Feed water valve
  • Tank ball valve
  • Additional inserts and fittings

Overview of Features

With 6 stages of filtration, the iSpring RCC1UP 6-Stage has plenty going for it. Let's start with the size: the total package is not small, at 17x14x23 inches and weighing 36 pounds. If you take out the storage tank and accessories, the filtration system itself accounts for 14.5x7x19 inches.

The storage tank can hold up to 3.2 gallons of purified water, while the system can output 100 GPD at 50 to 60 psi (measured at 77º F). Thanks to the included booster pump, however, you can have water supply pressures as low as 45 psi and still output decent amounts of water.

Remember that the RCC1UP cannot intake hot water. The temperature of the water should be between 40 and 100º F and the pH should be between 3.1 and 11.0. The system should also be connected to a 110V power source for the booster pump and UV light to work.

Now let's take a look at the filtering stages, which do a great job of relieving the water of all nasty things. First, we have a sediment filter to remove visible detritus from the water, such as rust, dust, and particles. This is followed by a granular activated carbon filter that removes chlorine from the water, along with foul odors, tastes, and smells. The third stage is a carbon block that has the same job as stage 2, for a more thorough cleaning.

At stage 4 we have the reverse osmosis membrane. It gets rid of contaminants like arsenic, asbestos, cadmium, mercury, uranium, and more than you can name. The filter has impressive rejection rates, above 90 percent for almost every substance listed in the specs.

Stage 5 consists of a post-carbon filter, that basically disposes of any tastes and odors that would still remain after 4 filtration stages. And if this wasn't enough, stage 6 finishes it off with a UV light that kills any dangerous microorganisms in the water, like bacteria and viruses.

How to Use It

Installation of the RCC1UP can be tricky, so don't try to do it yourself if you are not experienced with plumbing. In this case, it is best to hire a plumber to do the job for you. In any case, here's a video tutorial to walk you through the installation steps.

Keep in mind that this type of system requires some maintenance. The filter cartridges in stages 1-3 should be replaced every 3 to 6 months, depending on the quality of your water. Stage 5 should be replaced every year, and the UV light on stage 6 should be replaced when the light goes out, which should also be once a year.

The reverse osmosis membrane is the one that requires the least maintenance, as it only needs to be replaced every 2 to 3 years. For more information about this, you can always check the user manual.


One problem with most reverse osmosis water filter systems is that they tend to slightly acidify the water because they remove some beneficial minerals from it. If you are worried about this, then you should probably try the iSpring RCC1UP. It is slightly more expensive but has an additional alkaline mineralization stage that replenishes some of the lost minerals to increase the water's pH.


There may be some issues with the quality of household water, but at least nowadays we have viable solutions to drink tap water and not worry too much about our health. We took a look at one of these solutions, the iSpring RCC1UP. Its price tag may be a bit above other reverse osmosis systems, but it is mighty impressive when it comes to purifying water and making it safe to drink. It even includes a pump to increase water pressure and a storage tank to always have fresh water available. In our opinion, it is totally worth the investment.

Brondell H2O+ Reverse Osmosis Water Filter System Review

Brondell H2O+

If you want the closest to 100% clean drinking water, chances are you’re not going to get there without a reverse osmosis (RO) filter. Filtering water through RO is the most efficient method approved by government institutions. The only downside with some systems is that they tend to have a high water waste rate.

This article will present you with one of the few RO units that don’t have this drawback. It is a point-of-use filtration unit that comes with a water tank and supports a decent water pressure range. Here are the details on how it works and how you can get your hands on it.

Brondell H2O+ Review

The Circle system from Brondell is a rather new product. It first hit the market in the summer of 2015. It was designed to be efficient at cleaning water with less waste water than other RO units. Since its release it has managed to maintain its popularity among customers, and for good reason.

RO filtration units are the most effective by far at eliminating heavy metals, chlorine and fluoride from water. What makes the Brondell Circle even better is that the RO membrane is also accompanied by a sediment filter and two carbon filters. This way it tackles more contaminants than most products in this category.

While it may not be the easiest to install for everyone, it can still be a DIY project if you follow the instructions carefully. The customer support team at Brondell did a great job at providing instructional videos and accompanying texts and diagrams in the manual.

What’s even cooler about this system is the water storage tank. This fills up in about one hour and allows you to have clean, ready-to-drink water at all times. Most RO filtration units tend to mess with pressure levels and limit flow rate due to the inefficient process of pushing water through the RO membrane, and the Circle is no different.

Brondell H2O+

Who is This Water Filter for?

Despite its rather bulky appearance, the Brondell H2O+ Circle is a water system filter that can fit under almost any kitchen sink. So whether you live in a small apartment or a large house, you can benefit just as much from having the Circle system installed.

The installation process can be a bit more complicated if some requirements are not met. You might need drilling and extra accessories to fully integrate the Circle in your home. Because of this, it might not be a good fit for people looking for a DIY project, even though the instructional videos are quite detailed.

The Circle has four filtering stages which can deliver exceptional quality drinking water. That being said, it is only a point-of-use system so it won’t affect the rest of the water in your house. If you have trouble with sediment concentration damaging your appliances or chlorine gas release in the shower, the Brondell Circle will not be enough.

What’s Included?

All parts needed for installation are included but you’ll have to supply your own tools or call out a professional plumber. This is what you will find included with your purchase:

  • Chrome faucet
  • Led indicator that shows when to change the filter
  • Twist and seal filters
  • RO membrane
  • Sediment filter
  • Two carbon filters
  • 1x CR2 battery
  • Manual

Overview of Features

Besides the RO membrane, there is also a sediment filter as well as two carbon filters that help deal with rust, dust, chlorine and other contaminants. These extra filters allow you to get the most out of the RO membrane.

The filters can be changed every six months and their replacements can be purchased individually or in sets. The RO membrane is the most durable as it can last up to two years.

The unique design of the Brondell Circle only wastes a little over 2 gallons of water for every gallon filtered. This is an impressive improvement upon the average which is 24 gallons for most RO systems. It achieves this lower waste rate by using a flexible reservoir that reduces back pressure on the RO membrane.

Another benefit of the design is lower pressure drop, which means higher flow rate at the outlet. According to the manufacturer, many competing designs of similar capability have to rely on a built-in pump to achieve the high flow rate and low pressure drop of the Circle.

Brondell H2O+ Installation 

The Brondell Circle may seem easy to install at first glance. Truth be told, while you don’t need technical skills to complete the installation, you do need a lot of patience and some tools lying around the house.

The Circle uses three different plumbing connectors. While the markings on the casing are self-explanatory as to which tube goes where, the water waste tube can cause you some problems. If your sink’s disposal tube is not equipped with a tiny hole that can connect it to the Circle unit, you will have to drill one.

Your sink should also be equipped with an additional 7/16 inch hole in order to install the faucet that comes with the Brondell. You don’t have to change your sink if you don’t have an opening because one can be drilled or cut. Again, this takes tools, some skill, and a lot of patience.

Luckily these are not tasks beyond the capabilities of any decent plumber so you could ask for professional help. If you’re set on tackling the DIY project then follow the step-by-step instructions in the manual. This video is also highly recommended:

There is also a first-time-use cycle you should follow. Alternate between running water, letting the tank fill up, and then empty for a while before you start drinking. You can find the correct intervals in the instructional video and it is important that you follow all the steps. Your water will not be clean enough to drink at first.


It’s hard to find any major drawbacks of the Brondell Circle apart from the low flow rate. Even if it is one of the best for RO systems without a built-in pump, it may not be enough for you. If that is the case, you can check out the APEC RO-90 filtration system.

This unit can handle up to 90 gallons per day at 60 psi which is almost twice as much as the Circle. It also uses multiple filtering layers to remove a wide range of contaminants. The downside of this system is its tricky installation process with even harder to fit tubes and connectors.


The Brondell H2O+ Circle is one of the best RO water filtration units you can get. Although it is a point-of-use design, the Circle still uses four separate filtering layers to clean water from sediments, microbes, bacteria, chemicals and heavy metals. It uses patented Brondell connectors and circuit technology to ensure higher flow rate than other non-electric RO filtering systems.

Express Water RO5DX 5-Stage Reverse Osmosis Review

Express Water RO5DX

Are you concerned about the environment and polluting agents that may be affecting your health? If you are, it is not without reason. New studies are published all the time claiming that something you usually eat or drink contains substances that may make you sick. Unfortunately, this is also the case with water. Many people end up buying bottled water to drink due to the pollutants that are present in tap water. Is there another solution? Yes, there is. Let us introduce you to the Express Water RO5DX, a reverse osmosis water filter system that's going to purify your water.

Express Water RO5DX Review

The RO5DX is a water filtration system that is meant to be installed under your kitchen sink. It filtrates your kitchen water using a process called reverse osmosis. Reverse osmosis is very popular nowadays since it is one of the most proficient and affordable filtration methods currently known.

Express Water is a specialist in filtration systems, and it has been in this business for over 25 years. The RO5DX is their most standard and reliable system, and there are several versions of it.

The ROALK5D has an extra filtration stage of small rocks, to increase the water's pH and add minerals to it. The ROUV5D features an ultraviolet light to kill most germs, bacteria, and viruses present in the water. There’s also the ROALKUV5D, which is a combination of the previous two systems.

The RO10DPU is yet another version of the RO5DX, featuring a booster pump to add pressure to the water. Finally, the RODI5D features a deionization module to remove total dissolved solids (TDS) from the water.

Who is This Water Filter For?

If you're here, then you're probably on the lookout for a good water filter to install in your kitchen. If you're not sure which one to get, or you just want a basic solution that does a good job filtrating water with no extraordinary features, then the RO5DX is for you.

Remember that the RO5DX has considerable dimensions, especially when you take the water storage tank into account. So if you are planning to get a water filter system for your RV or small apartment, this might not be the best solution.

What’s Included?

When unboxing the RO5DX, you'll find that this system comes with everything you would expect and more. All required valves and tubes are there, and even some Teflon tape. Best of all, you get an extra 5 filters to save you the trouble of ordering the first replacement set.

All that is missing are some household tools required to perform the installation. The box contents are:

  • 5-stage reverse osmosis system
  • Drinking water storage tank
  • Designer faucet
  • Feed water valve
  • Drain saddle valve
  • Color tubing
  • Flow restrictor
  • Storage tank shut-off ball valve
  • Feed valve
  • Filter housing wrench
  • Extra locking clips
  • Leak stop valve
  • Teflon tape
  • Extra filter set

Overview of Features

So, let's take a look at the RO5DX's specifications. The system can output a maximum of 50 gallons of water per day, which is reasonable, but not spectacular. Still, the storage tank means you can have 4 gallons of water at your disposal if you need a large amount of water quickly, which is nice.

This system works with the water's existing pressure, so it should be at a minimum of 40 PSI, and a maximum of 80 PSI. It cannot handle hot water, so the feed water temperature should be between 38 and 100º F. It is not exactly lightweight, with a combined total of 28 pounds. Finally, the maximum TDS in the feed water should be 1000 parts per million (PPM).

Let's take a look at the filtering stages. The first stage is a sediment filter that removes sediments from the water such as rust, dirt, sand, and silt. It is followed by a granular activated carbon filter to get rid of chlorine and organic chemicals, along with foul tastes, odors, and colors present in the water.

The third stage is a carbon block similar to the previous one, to remove anything that stage 2 missed. The difference is that this one is a block of carbon.

Last but not least, we have the top filters, stages 4 and 5. Stage 4 is a reverse osmosis membrane filter to remove most contaminants and chemicals that weren't eliminated before. These include bacteria, viruses, TDS including cadmium, lead, and mercury. Stage 5 is a post-carbon that eliminates any remaining traces of chemicals, odors or bad tastes. For this reason, it can also be called the polishing filter.

How to Use It

Installing the RO5DX is not exactly a trivial matter unless you have some experience in plumbing. If you don't, it is advisable that you seek the assistance of an expert.

Before starting the installation, you should make sure you have all the required material. This includes everything that comes in the product box, plus some tools:

  • Box cutter
  • Phillips screwdriver
  • 1/4” drill bit for the waste line connection
  • 1/2” drill bit for the faucet hole
  • Wrench or adjustable wrench

You'll find a proper express water reverse osmosis manual provided by Water Express.

The manual also includes some helpful tips on how to store the filters and perform maintenance on the system. Bear in mind that you will also have to replace the filters every now and then. Stages 1 to 3 should be replaced every 6 months and stages 4-5 should be replaced once a year.


While the RO5DX is a great water filter system, it may sometimes let some microorganisms slip by. If you are concerned about this, then try the ROUV5D, with an extra filter stage consisting of a UV light to get rid of viruses, bacteria, and even algae and fungi.

An aspect of the RO5DX that could be improved is its water output capacity, which is only 50 GPD. If you feel this is not enough for you, then try the RO10DPU. It works for waters with low pressure and can output a whopping 100 GPD.


We've looked at the Express Water RO5DX, a solid contender among water filter systems. Its 5 filtering stages are sure to make tap water in your home much safer to drink. With an affordable price and a complete package, it is quite a great buy.

Overview of Features

This water filter system is packed with features. And, it is one of the best RO systems available on the market. Key features include:

Modular filter design

First, the Home Master TMHP has an all-in-one modular filter design. This means that the filter housing and filter are integrated. And, the entire filter can be removed and disposed of.

This eliminates the possibility of microorganisms, sediment, and biofilm building up in the canisters. When that happens, it will ultimately weaken the canisters. And, this causes it to leak and fail.

Better tasting water

Some filter systems leave metallic, horrible tasting water. It may clean it, but the result is unpleasant to drink. This is not the case with this model.

This TMHP model produces clean water by putting it through 9 stages of cleaning. The system filters, purifies, sterilizes, and enhances the water before it gets to your drinking glass.

Also, the system re-mineralizes the water. This restores the pH balance of the water in the storage tank. And, may reduce the acidic taste typically associated with reverse osmosis-filtered water.

UV light

Don’t want to fight microorganisms with chemicals in your water? This model uses a UV light instead. It’s more effective than using chlorine, and doesn’t affect your water’s chemistry.

Filters easy to change

Changing the filters for this system doesn’t require wrenches or heavy tools. It doesn’t even require superhuman strength. The push-in fittings and design make it relatively easy to do the annual filter changes.

Better water efficiency

Next, don’t worry about slowing your faucet down to a trickle. The components for this unit are conducive to a higher flow rate. And, it almost doubles the water rate that flows from the tap.

Reduced water waste

Finally, did you know that reverse osmosis systems can waste a lot of water? In happens with a lot of systems.

But, the permeate pump included with this unit reduces water waste. This non-electric pump improves the unit efficiency. And, may reduce waste by up to 80 percent.

As an added bonus, the efficient system may also increase your water production by up to 50 percent.
