When looking for an all-in-one water filtration system that’s dependable and affordable, our research showed that you can’t go wrong with the iSpring RCC7. This multi-layered system filters over 1,000 different types of contaminants, ensuring clean and healthy water in the home. Although this is not a whole house system, it delivers amazing results at a great price!

What makes the RCC7 one of the best systems out there is its five-stage filtration which eliminates bacteria, viruses, iron, lead, mercury, chlorine, asbestos, and much more. The system consists of three pre-filters: the polypropylene (PP) sediment filter, the granular activated charcoal (GAC) filter, and the carbon block (CTO) filter.

The PP sediment filter removes sediments, dust, sand, dirt, and rust from the water, while the GAC filter ensures that no chlorine comes through. It also makes the water odorless and colorless, while removing foul tastes and cloudiness. The third pre-filter, the CTO filter, removes chloramines and other harmful chemicals.

Here’s what we really loved:

The heart of this excellent filtration system is the RO (reverse osmosis) membrane. It’s a very fine membrane that removes contaminants down to 0.0001 microns. This basically means that nothing except water molecules is able to pass through. After the RO membrane, another GAC post-carbon filter removes possible residual tastes and odors, ensuring perfectly clear and healthy water.

All the filters have to be changed about once or twice a year, depending on water quality and hardness. The only exception is the RO filter, which should be changed after two years. The replacement filters are inexpensive and easy to come by.

With its 75 gallons per day capacity, the RCC7 is perfect for home use. What also sets it apart from most other filtration systems is that it looks great. It also comes with a convenient and visually enticing lead-free brushed nickel faucet.

This system is small enough to easily fit under any sink, and even a beginner can install it in about two hours. All the installation pieces and equipment come with the system, and there is also an instruction manual, as well as many handy YouTube installation videos available. iSpring also offers live phone support, and while doing our research, we’ve confirmed that this company’s customer service is unparalleled.

Our research also showed that there are a few downsides to this iSpring RCC7 RO system. Firstly, the faucet included in the package sometimes starts dripping. Some users report that it started dripping right away, while most report that the dripping begins after six or more months of use.

We also found that the installation manual that comes with the product is a bit outdated, and does not include all the items that come with the product. Luckily, the YouTube videos by iSpring are very convenient and helpful, so the mistakes in the installation manual can be overlooked.

There are some very popular add-ons that go with this product. iSpring ICEK Ultra-Safe Fridge Water Line Connection and Ice Maker Installation Kit is used to connect the water filtration system to the ice maker or water dispenser of a refrigerator. This kit contains all the items you need to install it, including tubing, valves, and a compression fitting set. It’s easy to install, even for beginners, and there are absolutely no tools required.

There’s also iSpring 1-Year Filter Replacement Supply Set for 5-Stage Reverse Osmosis Systems. The set includes two of each of the pre-filters and one post-filter. Each filter is wrapped individually. This replacement set is meant to cover your replacement filter needs for a full year. Note: this set doesn’t include a replacement RO membrane, only pre- and post-filters.
