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.

Alternatives

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.

Conclusion

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.
