## Overview

The Aquasana AQ-RO3-RM Replacement Remineralizer is a genuine, certified component designed exclusively for the OptimH2O Reverse Osmosis system. It removes over 95% of fluoride and up to 99% of 89 contaminants while restoring essential minerals like calcium and magnesium for healthier, better-tasting water. Easy to install without tools, it requires replacement every 12 months to maintain peak performance and water quality.

## Description

The OptimH2O® Reverse Osmosis + Claryum® Remineralizer Replacement replaces the Reverse Osmosis Remineralizer of the OptimH2O® Reverse Osmosis + Claryum® (AQ-RO-3.55/56/62) and lasts for 12 months. Paired with the Carbon and Claryum® filters and RO Membrane in the OptimH2O® Reverse Osmosis + Claryum®, these filters effectively remove up to 99% of 89 contaminants, including fluoride. In all, the OptimH2O® Reverse Osmosis + Claryum® removes 5X more contaminants than other RO systems, while maintaining the benefits of healthy minerals other reverse osmosis systems remove.

Review: Quality Filters for Quality Water - The Remineralizer really makes a difference to our Reverse Osmosis. There is nothing like a glass of good-tasting water, and that is what these provide. We have them on 6 6-month subscription. I swap out the old one when I do my filter replacement. They are really easy to install because of the push-to-connect fittings, and there is no problem with leaking.
Review: Great taste and good flow rate - This adds more minerals back in than some other brands. I even have a different brand RO filtration system and converted it to fit this for the better quality. Uses 3/8 tubing so you might need to get a 1/4 to 3/8 conversion kit if you want to use it.

### ⭐⭐⭐⭐⭐ Water tastes better and easy to install
*by J***L on May 26, 2025*

Easy to install and gives my water more flavor over straight RO water.
