The THD-RO3-RO Reverse Osmosis Membrane is a replacement for the THD-RO3.56 OptimH2O Reverse Osmosis Drinking Water System. Aquasana OptimH2O delivers the best drinking water available for optimal hydration. It is the first system of its kind to pair powerful reverse osmosis filtration with Claryum selective filtration PLUS re-mineralization. Removes the most contaminants from your water while maintaining the benefits of healthy minerals that other reverse osmosis systems simply remove. Reverse Osmosis is the only proven water filtration method on the market to effectively remove fluoride from regular tap water. Aquasana’s filter removes over 95% of fluoride for optimally healthy, clean water. The OptimH2O also re-mineralizes water to put back the healthy minerals lost in the reverse osmosis process like calcium, magnesium, and potassium for optimally alkaline, pH balanced water.
- Replacement cartridge for AQ-RO3.56
- RO membrane should be replaced every 1-3 years based on water quality and usage for optimal filter effectiveness
- Other reverse osmosis systems typically reduce 5-15 contaminants, Aquasana reduces 74
- Reverse osmosis reduces 14 impurities including fluoride, nitrates, nitrites, lead, radium, and arsenic
- Selective claryum filtration reduces 60 contaminants including chlorine, chloramines, heavy metals, pesticides, and herbicides
- Re-mineralization designed to provide healthy amounts of calcium, magnesium, and potassium for optimally alkaline, pH balanced water

We’ve had our unit for two years now and still going strong! We installed it into our 50ft sailboat and no matter where we go we know that we have the best water to drink and cook with!

I have used an Aquasana filter in the past to remove chlorine and other impurities but I have become very concerned about the effects of Fluoride on our cognitive abilities. This filter takes 95% of Fluoride out. I’m also adding a 2nd mineralization cartridge

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.

We have gone through a full year now with complete replacement of all the filters which were very easy to replace – the auto ship made it a very simple project as we had all the filters for replacement. The water quality is excellent and we highly recommend this company and their products!

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.

With fast and easy installation, this is an awesome filter and system. I can taste the difference between the chlorinated water and the Aquasana pure water.

I replace all of my filters once a year and just a few every six months. Facing the first full replacement, I had my doubts and concerns about the job. It couldn’t have been easier unless someone else actually did it for me!

This brought the already-high pH 10.5 water up to pH 11.5 – which was tested on a calibrated pH meter. Rather too high for drinking water. Additionally, it was not until I got the system that I learned high pH water requires more-frequent replacement of the reverse osmosis membrane (also every 6 months). Our water has such high pH due to “lime softening” at the municipal water treatment plant.

Love that it filters so well, however it’s so hard to install and replace filter- but that doesn’t stop me.

We purchased our Aquasana filter system over a year ago and just love it. Got rid of bottled water for good.
