Product details
The OptimH2O® Reverse Osmosis + Claryum® Membrane Replacement replaces the Reverse Osmosis Membrane (Stage 2) of the OptimH2O® Reverse Osmosis + Claryum® (AQ-RO-3.55/56/62). This replacement filter is tested and certified to NSF/ANSI Standard 58 to reduce 95% of mercury, 97% of chlorine and arsenic, and 99% of microplastics, and asbestos. Effectively remove 89 contaminants, including fluoride. Paired with the Carbon and Claryum® filters 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 health minerals other reverse osmosis systems remove. With the combined power of reverse osmosis, selective Claryum® filtration, and remineralization, you have immediate access to clean, healthy water for drinking, cooking, washing your vegetables, and more.
Each filter lasts up to 12 months and is easy to replace. No need to disconnect hoses or water lines - simply twist off and replace. Use only genuine Aquasana replacements with your Aquasana system. Untested replacements are not certified for performance capacity or contaminant removal.

The Best
Installed in 2017, installation was fairly easy, instructions weren't clear/detailed enough in some areas. Had a leak coming from the faucet connection and a replacement was promptly sent. Filter replacements are quick and easy, again instructions weren't quite clear enough but eventually figured it out. The water taste great, have had visitors say that it was the best water they had tasted. Great peace of mind knowing I no longer have to drink fluoride tainted water not to mention all those contaminants.

I would by this product again
I have had this water filter system for one year now. I love how this water taste. I know I am getting a better quality of water through this system. Before my water system, the water from my tap, or filtered refrigerator water would leave a pink residue build up in my dogs water bowl. Since we installed the water filter system, that has never happened. That right there tells me something about the difference.
