About This Product

Certified to NSF/ANSI 58, the RCC7AK water filter is a multi-layered reverse osmosis system under sink that provides optimal protection against over 1,000 different types of contaminants, removing up to 99% of rust, sediment, taste, arsenic, asbestos, chlorine, hormones, fluoride, lead (up to 98%), mercury, sodium, and more. Featuring some of the longest-lasting filters in the industry, the reverse osmosis water filtration system consists of 6 stages water filters, each one designed to progressively remove contaminants and improve water quality. After flowing through the initial 5 stages of the iSpring RCC7 line of reverse osmosis filtering products, the RCC7AK RO system adds another alkaline remineralization (AK) stage. This stage is designed to restore the natural alkalinity and mineral balance of the water. The RO membrane effectively generates pure water but also removes a few helpful minerals. The red mineral stone portion of the AK water filter adds back healthy minerals including calcium, magnesium, that other systems don't. The calcite portion of the filter neutralizes the pH of the RO water. And the water tastes better too. Because RO water is so pure, some people may find it tastes unnatural. Many people prefer the more natural taste that comes from the presence of some minerals. Remineralization restores just the right proportion of healthy minerals.

I installed this yesterday and woke up to great coffee due to using this water. The difference in taste is amazing and best of all, no more plastic bottles. I fill up glass jars and keep in the fridge. I only wish I had bought this years ago.

This is our second iSpring RO system and thoroughly enjoy the quality. Our main system is a 500GPD system with a booster pump, which delivers a higher pressure than this model. However, this model (installed in our basement) works great for lower usages scenarios. If you have great water pressure, it will work amazing. If you have low water pressure, I would suggest a model with a booster pump. I use an alkaline filter downstream of this RO model and the well water tastes amazing. The tank is fine quality and helps leverage your water pressure with sudden large usages. ISpring is a great company that makes top tier filtration systems. I will always recommend iSpring, but different models are appropriate for different people depending on their usage, pipe size, pressure etc.

This filtration system is awesome. The water rate so clean and fresh. It is easy to install as well. Definitely worth it if you are looking to get fresh clean water straight from the sink. We use cpaps and it saves us a lot of money now that we dont have to buy water.
