Aquasana OptimH2O delivers the best drinking water available for optimal hydration.
OptimH2O is the first reverse osmosis system of its kind to pair powerful reverse osmosis filtration with Claryum selective filtration PLUS remineralization.
Remove the most contaminants from your water while maintaining the benefits of healthy minerals other reverse osmosis systems simply remove.
For a complete list of contaminants reduced please see our Performance Data Sheet.
Remove over 95% of fluoride without demineralizing your water for optimally healthy, clean water.
Reverse Osmosis is the only proven water filtration method on the market to effectively remove fluoride from regular tap water.
Remineralizes water to put back the healthy minerals lost in the reverse osmosis process like calcium, magnesium, and potassium.
Improves water pH balance for optimally alkaline drinking water.
Reverse Osmosis + Claryum® Technology + Remineralization
Osmosis Filters out dissolved solids smaller than 1 micron like fluoride and arsenic.
Carbon Reduces organic chemicals like herbicides, pesticides, VOCs and MTBE.
Carbon Targets chlorine and chloramines (chlorine + ammonia disinfectant).
Exchange Filters heavy metals like lead and mercury.
Absolute Sub-Micron Filtration Captures asbestos and chlorine resistant cysts like giardia and cryptosporidium.
Remineralization Puts back healthy minerals to improve pH balance & water alkalinity.
The result: Effectively removes >95% of fluoride plus over 70 other contaminants and puts back healthy minerals for optimal drinking water.
Easiest filter Replacement
Replacements engineered for ease. Eco-friendly carbon and Claryum filter housings easily twist off so replacing your filters is a snap!

Warranty & Installation
Read the Reviews
Do I need a plumber to install the system or can I install it myself?
Depending on your existing skills and experience, we recommend hiring a professional to install your reverse osmosis system. Installation does require drilling into your pipes which is not recommended for individuals unfamiliar with plumbing and permanent appliance installation. Please read through the owner's manual carefully before attempting to install the system. If you have any questions or need assistance, our technical support representatives at 866-662-6885 can walk you through the installation process.
How often do I have to replace the cartridges and membrane?
• Stage 1 (Carbon) and Stage 3 (Claryum) filter cartridges should be replaced every 6 months or 365 gallons. To make replacements easier and cheaper, these cartridges are eligible for our Water for Life auto-ship program. Get free shipping, the best discounts, and an extended product warranty by joining Water for Life.
• We recommend replacing Stage 2 (RO Membrane) every 2 years depending on usage and water quality. For homes with higher water usage and/or poorer water quality, you may need to replace your RO membrane every 1 to 2 years. For homes with lower water usage and/or better water quality, you may only need to replace your RO membrane every 2 to 3 years.
• We recommend replacing the remineralizer every 1 year depending on usage and water quality.
Is this purified water?
Yes. The Aquasana OptimH2O uses reverse osmosis to effectively purify your drinking water. In addition to reverse osmosis, the OptimH2O system also uses selective filtration to reduce over 60 other contaminants, plus includes a remineralizer designed to put back healthy minerals like calcium, magnesium, and potassium that are removed in the reverse osmosis process.
I'm a renter, so I can't drill or modify the plumbing. What should I do?
Unfortunately, drilling into your water pipes is required to install the Aquasana OptimH2O Reverse Osmosis system. If you already have an existing hole for a vegetable sprayer or soap dispenser on your sink countertop, our AQ-5200 and AQ-5300 Under Counter Drinking Water Systems can be installed without making permanent changes to your sink and are great options for rental properties. If there is not an existing hole on your sink countertop, we also have two countertop options that offer the same professional grade filtration as our under counter options (please see the Powered Water Filtration System or AQ-4000).
I have an existing filtration or side faucet from a previous system. Can I use that with my new Aquasana water filter?
The faucet included with the Aquasana OptimH2O is specifically designed and NSF tested and certified to work with our reverse osmosis system — any other Aquasana faucet or faucet from another filtration system not designed to work with a reverse osmosis system will not work for the Aquasana OptimH2O and may cause damage to your filtration system. If you choose to use another reverse osmosis air gap faucet, we recommend you enlist the help of a plumber to ensure proper installation.
Why is it important to flush my OptimH2O Reverse Osmosis System during the initial installation?
When RO membranes are manufactured, there is a preservative used to protect the membrane fibers from damage. This preservative needs to be flushed out after the system is installed and prior to drinking water from the RO system. In addition, the RO holding tank should be sanitized with a drop of bleach during the install. It is important to flush the system for the entire 24 hours during the initial install to ensure all the bleach from the holding tank is washed away before consumption.
What does TDS mean?
TDS is the acronym for Total Dissolved Solids, the amount of dissolved minerals and metals present in water. TDS meters tell you the concentration of dissolved minerals and metals, but are not an accurate measurement for contamination. Aquasana products reduce and remove harmful TDS like lead, but selectively retain or replace healthy dissolved solids like calcium, magnesium, and potassium. Aquasana OptimH2O comes standard with a 1 year remineralizer designed to replace healthy calcium, magnesium, and potassium lost in the reverse osmosis process.
Does the Aquasana OptimH2O remove fluoride?
Yes. The Aquasana OptimH2O is NSF Certified to remove over 95% of fluoride from your drinking water.
Does the Aquasana OptimH2O remove arsenic?
Yes. The Aquasana OptimH2O is NSF Certified to remove over 97% of arsenic from your drinking water.
How many gallons does the RO holding tank store?
The RO holding tank stores 3.2 gallons of water at a time.
What is the flow rate of the Aquasana OptimH2O?
OptimH2O flows at a rate of 0.8 gpm (gallons per minute).
