    Aquasana OptimH2O Reverse Osmosis Water Filter System with Claryum Technology & Remineralisation Complete with Australian Fittings

    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.

    Customer Testimonials

    Hi Rod,

    Thanks for the e-mail. I have just fitted the water filter system and it worked like dream so far, and everyone comments on how good the water tastes and it's great in the shower as it leaves no stains on the glass.

    Great investment would recommend to everyone 

    Joe from SA.

    Just letting you now my son is thrilled with the water filter he says the water tastes much better and softer and cumming from my son that's saying something.

    Great service from Rod and the team. Will be ordering again. 


    Hi Folks,

    Many thanks for the support in fixing my filter system. The idiot owner (me) forgot to read any change details. I changed 1 and 3 as instructed & I could hear it purging & the waste working so I hope to have 200ml in the next hour.
    Your RO water is very important to me for drinking but also in cooking (fermenting) but most of all in my distillation system for cutting 94% alcohol to 40%ABV & then making every kind of drink known to man.
    The results are so good that those local Pro fishermen voted my Rum better than Bundaberg Rum & I seem to be gifted lots of prawns now......
    Retirement in Hervey Bay is wonderful and your filter system makes the best water & sparkling ice.

     I can recommend purchasing whole of house filters and a UV replacement tube from My Water Filter, because Rod and his team are extremely helpful and their prices are very competitive. Will be ordering from them every year.

    Dear team at My Water Filter,

    What can I say.. Thank you. Thank you, for your professionalism through the purchase and delivery stages. Thank you for your extraordinary product. I could not be more happy with the purchase I have made with The Whole Home Filtration system.

    I have immediately noticed a taste difference in the quality of water and my body is responding to it in a positive way. I look forward to drinking water so much more now. My family all agree that it was a sound investment. All of our healths will benefit from the installation.

    What else can I say..

    Thank you.

    Andrew, NSW

    I really appreciate your professionalism. You are a gentleman and a scholar.
    I'm looking forward to catching up with you very soon.

    Kind regards,


    Hi Rod,

    Thanks so much for your help in choosing the correct under bench and replacement filters...Also for the prompt delivery of  both items  which are now installed and working well. I am very impressed  with the service you provide and will certainly be recommending  you to my friends.

    Kind Regards,

    Hello Rod,

    My gorgeous water filter arrived today and I just wanted to say thank you for a superb product. It was amazingly well packed (my biggest concern!) and is a beautiful addition to my kitchen.

    I'm so glad I found you. This means not only healthier drinking water for us but also no more buying pure water for my kombucha production.

    Many thanks and best wishes to you,

    "Thanks 'My Water Filter' I am very impressed with your service."
