iSpring RCC7 Reverse Osmosis System Review

iSpring RCC7 filter

The iSpring RCC7 is our #1 budget choice for a reverse osmosis system. Specifically, it is an excellent choice for those looking to purchase their first RO system. We briefly mentioned it in our extensive article on reverse osmosis systems.

The RCC7 is a five stage reverse osmosis filter that can filter up to 75 gallons of water per day. This isn’t a whole house filter. Instead, this unit fits right underneath your kitchen sink. It then has its own faucet that you must use when you want purified water.

Don’t worry, the faucet looks great and looks good with any modern kitchen.

This article will go into more detail on this system and discuss the filtration process, efficiency, reliability, the warranty, installation, and maintenance. Just don’t let the low price scare you away. iSpring makes some amazing products and the RCC7 is no different.

Filters

The most important part of any water filtration device is the methods that they use to filter water. Fortunately, the RCC7 has good processes in place.

In fact, it has 5 different filtration stages:

Sediment filter: This stage removes only the largest sediment (rust, dirt, etc.), which extends the lifespan of the other filter components.

Granulated activated carbon (GAC) filter: This filter removes gases and vapors found in the water and some chlorine.

Chlorine, Taste, Odor (CTO) Filter: Another activated carbon filter. As the name suggests, it will remove chlorine, taste, and odor.

Reverse Osmosis Membrane: The filtration step that you are paying for, everything else is just a lead up to this step. We explained how reverse osmosis works here.

Just know that reverse osmosis removes 99.9% of everything in water. Yes, that includes fluoride. The process does waste a decent amount of water though.

Inline Post-carbon filter: There is a small inline carbon filter that removes any remaining chlorine, taste, or odor. Honestly, there isn’t going to be much of anything, but it’s nice to have the added protection.

EfficiencyReliabilityWarrantyMaintenance

Reverse osmosis has a bad reputation for the amount of water that it wastes. This unit actually operates much more efficiently than most reverse osmosis systems on the market.

It wastes 2.5 gallons of water for every 1 gallon of clean water produced. A 2.5:1 ration. Not bad.

The industry average hovers around 4.

These units are highly reliable. The RCC7 has a Gold Seal from the Water Quality Association (WQA). WQA specifically tests for reliability, maintenance, and filtration. The RCC7 met all the criteria and received the Gold Seal.
You receive a 1-year money back guarantee and a 1-year manufacturer warranty (they run at the same time) when you purchase this system. Simply register the product on the company website after purchase.

Maintenance on the iSpring RCC7 is easy. All you have to do is change the filters.

The RO membrane needs replacing every 2 years. GAC and CTO filter need to be changed every 3-6 months. The sediment filter and post-filter can be changed every year.

Installation

Installing these is relatively easy. Most homeowners can probably do it themselves.

If you do not feel comfortable, then any licensed plumber in America can easily install it.

The instruction manual is awful. We recommend watching this YouTube video they published.

You can always call their customer support line (678-261-7611) if you get stuck. WQA certified representatives can help you through the whole process. They are open Monday to Friday 9AM-5PM EST.

  • 2.5:1 efficiency is extremely good for a reverse osmosis system. You will waste less water with this unit compared to other more expensive ones.
  • 1-year money back guarantee and a 1-year warranty (run at the same time). Just remember to register the system on their website.

Cons

  • They can eat filters fast if you have heavily chlorinated water. This applies to every system though.
