The Activated Carbon Plus filter reduces particulate materials such as sand, rust, and fine particles from the water supply. This first stage also acts as a pre-filter protecting and extending the life of the following filters. The final stage in the filtration process, the Carbon Block filter further reduces any lingering water contaminants such as chlorine and volatile organic compounds (VOCs), improving the overall taste and odor of the dispensed water.

It removes over 1,000 contaminants, including chlorine and lead, with a potential TDS rejection rate of up to 99%. Advanced features include an LED UV light and a smart flow sensor for optimal performance. Built-in filter life indicators prompt timely replacements, and installation is simplified with integrated-water-route technology and a compact design.

The iSpring RO800G is awesome and it is very easy to install. Very much a DIY installation. Their installation videos are extremely helpful. You do need to be a little more handy and savvy if you are installing the UVF8 and even more if you want to install the remineralization filter as well, as I did. But even then it was not hard at all. Thank you Sean for also making the warranty registration process one of minimal effort on my end.. Jp. Houston, TX. Thu Jul 02 2026

iSpring RO500-BN, NSF Certified Tankless RO Reverse Osmosis Water Filtration System, 500 GPD Fast Flow

Had the hire a plumber to install this. Very quick and easy, except for making a new hole for the dispenser to be mounted. Water comes out quickly and the taste is amazing. You can easily tell the difference! I’m excited to have this and hope it lasts for many years to come! Highly recommend!. Karen. Woburn, MA. Sat Jan 01 2022

Different installation and systems but it seems to be working fine. Highly recommended. Ivan. Miami Lakes, FL. Fri Oct 02 2026

The RCC7P-AK is unequaled in quality, performance and durability. The system consists of 6-stage, layered filtration built around precision reverse osmosis (RO) technology that removes over 1000+ different kinds of contaminants in order to provide the best home drinking water filtration available. It features a 75 GPD capacity RO membrane, which is larger than most in its class and provides the capacity to economically handle the drinking water needs of even a large family. The RCC7P-AK model is equipped with a booster pump for situations where inlet/house water pressure is low – below about 40 psi. After flowing through the initial 5 stages of the ISPRING RCC7 line of Reverse Osmosis filtering products, the RCC7P-AK also adds another Alkaline Remineralization (AK) stage. This stage is designed to restore the natural alkalinity and mineral balance of the water. The RO process effectively generates pure water but also removes a few helpful minerals in the process. The red mineral stone of the AK filter adds back healthy minerals including calcium and 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.

excellent item, easy to follow instructions for install, and the water tastes great-pleased with my purchase, fair price. Gkl. Colorado. Thu Feb 05 2026
