    Aquasana OptimH2O Reverse Osmosis Water Filter System with Claryum Technology & Remineralisation (AQ-RO-3)

    Ultimate Purity

    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.

    OptimH2O removes:

    95% fluoride and mercury 97% chlorine and chloramines 99% lead, asbestos and arsenic

    our reverse osmosis filters 5 times more contaminants

    For a complete list of contaminants reduced please see our Performance Data Sheet.

    Goodbye Fluoride

    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.

    Healthier Drinking 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.

    Pure Performance

    Reverse Osmosis + CLARYUM® Technology + Remineralization

    Rever Osmosis

    Filters out dissolved solids smaller than 1 micron like fluoride and arsenic.

    Activated Carbon

    Reduces organic chemicals like herbicides, pesticides, VOCs and MTBE.

    Catalytic Carbon

    Targets chlorine and chloramines (chlorine + ammonia disinfectant).


    Filters heavy metals like lead and mercury.

    Absolute Sub-micron Filtration

    Captures asbestos and chlorine resistant cysts like giardia and cryptosporidium.

    Why Buy an Aquasana Water Filter


    Puts back healthy minerals to improve pH balance & water alkalinity.

    The Aquasana Re-Mineraliser uses a dual media called calcite and Magflow. As the water passes from the holding tank to the stage 3 filter, potassium is added to the water through the potassium Ion exchange process. Next the water passes through the remineralizer and will pull only the mineral content it needs in order to stabilize the pH of the water. The minerals it pulls are magnesium and calcium. The remineralizer isn’t a pH enhancer, It’s a pH stabilizer

    1. Is the calcium natural? Yes, it’s just formulated into a non-scaling form of calcium.

    2. Is the magnesium natural? Yes, it’s just formulated into a magnesium media stone.

    3. Is the potassium natural? Yes, it’s formulated into the carbon block as a potassium zeolite media.

    4. Is it safe? Yes, testing has been done through NSF for safety and all medias are ANSI/NSF 61 certified. This is why NSF allows it to come as a standard part of the system. Without the safety testing, NSF won’t allow us to sell it as part of the NSF certified system.

    5. What will my pH be after it runs through the remineralizer? The goal is to keep it around 7

    6. Will it increase my TDS levels? Yes… TDS is reduced at 95% and since TDS is a measurement of Total Dissolved Solids (aka minerals), the TDS levels won’t be at 0.

    7. What will my TDS levels be? This depends on the amount of TDS that was in the water before purification. Since the TDS is reduced at 95%, there will still be 5% of the total TDS remaining in the water. The remineralizer will add on to that and the amount of TDS added will be determined on by the alkalinity and pH of the water. Average TDS added will range from 50 to 200 depending on the alkalinity and TDS levels of the water prior to purification.

    8. If I already have a low pH level will the remineralizer bring it back up to 7pH? In some cases yes but not in all cases. It really depends on how low the pH is before purification. The lower the pH, the more difficult it is to bring it back up to a 7pH. However, most municipalities have pH levels above a 7pH and starting out with low pH is rare.

    THE RESULT : Effectively removes >95% of fluoride plus over 70 other contaminants and puts back healthy minerals for optimal drinking water.

    Hi My Water Filter

    We recently received our water filter and My Water Filter generously supplied two  additional small ones for a secondary tap in the bathroom and one to give to a friend.

    Having moved from Brisbane recently we found the hygiene and taste of tank water a little unpalatable. Once I fitted the filters which took next to no time to fit, we confidently went back to drinking litres of water a day. The taste was so much more superior. 

    I can honestly recommend their products. 

    Thank you Rod



    "You're da' man Rod. Big mahalos (thank you's) for your customer service and ethics. Big joy to you... Brian"

    We are very happy with our filter. Arrived promptly, was easy to put together and we are all enjoying the great taste of the water. Thanks for living up to your statements on the website!!

    "Hi Rod,
    You are a whiz!
    Thank you so much for assisting us via telephone to sort out our replacement filters.
    We are so pleased to be able to use our system again & it's good to know that. You'll now contact us in a year's time with all that we need. Brilliant!
    We appreciate your friendly, sincere care & will definitely be recommending your company to others."
