Filter Type: This iSpring RCC7AK water filter is an under-sink RO (Reverse Osmosis) drinking water filter system.

No. of Filtration Stages: It includes six different filtration stages to make the water clean and pure for drinking.

Filter Media: Filter media includes PP sediment filter, granular activated carbon (GAC) filter, and carbon block filter.

Also, there is an RO membrane, post-carbon filter, and the pH filter.

Removal of Impurities: The high capacity 5-micron sediment filter is responsible for eliminating dirt, dust, rust, sediment, and sand from water. In the second stage, water meets with a GAC filter that removes chlorine taste and odor along with cloudiness and colors. Next is the CTO filter that extracts chloramine, VOCs (Volatile Organic Compounds), harmful chemicals, and more.

The 0.0001 micron RO membrane is at the fourth stage of filtration where the water gets free from other harmful pollutants and a few minerals. The fifth stage features a post-carbon filter that eliminates any possible residual taste and odor. And the last and final stage has the pH filter or alkaline Remineralization filter that is responsible for restoring healthy minerals (calcium, magnesium, sodium) and producing balanced alkalinity. This results in more natural water taste.

Production Capacity: The RO membrane can produce 75 gallons of clean and pure water per day.

Waste Water Ratio: 3:1 is its waste water ratio. It wastes 3 gallons of water to give 1 gallon of pure and healthy drinking water.
