    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

    Thank you for the good service. I am also impressed that you are readily available on the phone for advice as well. Thanks

    Thank you.
    I have no complaints with the product, the service, delivery times or packaging.
    Very happy.
    Can taste the difference in the water quality immediately, and as it runs through our business ( fitness centre) we have had good feedback from our members.

    To the team @ My Water Filter- a huge thank you! I purchased the Fill2Pure fluoride filtering water jug and could not be happier! My Fill2Pure jug is used daily to provide the most deliciously pure water I have ever tasted! I love the simplicity of the filter system, how easy it is to set up and clean! The team at My Water Filter are professional and deliver a valuable customer experience. I love the charitable aspect to their business, this being the reason I chose them over online competitors! A special thank you to Rod who helped with a query I had concerning postage, with a return phone call within minutes of having placed mine. Delivery was so prompt I embarassingly wasnt sure if the product was mine and had to speak with Rod for reassurance! I recommend My Water Filter to anyone looking for a community minded company that believes in it's values or anyone who needs a new water bottle, jug, filter or home purifying system! Great product, great service, great customer experience! 

    Hello My Water Filter people, I am so happy to have found you, not only because of the wonderful service you are giving to the people with water shortages, but because you have saved us money and we received our order practically overnight, we are very particular in giving our guests at our Bed and Breakfast safe drinking water, so it is a win win in our books 

    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,


    Received reminder via e-mail to replace filter in shower.

    Ordered on-line, very easy process.  Received confirmation e-mail then a follow up for an alternative address.

    Filter arrived about a week later, installed and working as it should.

    Whole process was very easy and the reminder system is great.



    At first we were disappointed with the very slow flow from the top chamber, after contact with your office we were told that the problem could be blocked air. After soaking the filter again for a further half hour the excess air escaped, the flow then increased considerably. The water tastes great. Yes please use this feedback on your site, it may well help your future customers !


    My water filter arrived quickly, was so simple to install I didn't even have to use a tool, and I had fresh, delicious water in moments!!  I'm so happy with it, my daughter is looking at ordering one as well.

    I was able to get the filter system primarily because you offer AfterPay...so a big THANK YOU!  Makes ordering quite affordable and manageable, spread over 4 payments made fortnightly.    

    Clean water is so precious these days; having this filter system means I can now drink pure water without the guilt of using plastic bottles anymore and affords me peace of mind that I'm not drinking heavy metals, fluoride or glyphosate.  These things matter to me.

    I couldn't be more impressed with the service I received from My Water Filter. I was unsure as to which filter to buy so I rang and spoke to Rod who helped me decide. I had a query when the filter arrived and again Rod talked me through checking things. The filter works beautifully and I love the taste of the water. I went with the 0.1 micron because of the new influx of bats dirtying my roof and my drinking water. Thank you again.


    Hi Rod,

    It was great talking to you today about my new water filter, and I really look forward to getting it up and running.

    I love what you’re doing to help the world have clean and safe water, and by buying the filter from you, I feel like I’m doing something to help as well.
    I buy my toilet paper online from Who Gives A Crap, and 50% of their profit goes to providing toilets in the developing parts of the world, so I’m contributing that way too.

    Thanks again for the great service; you made buying a water filter a whole lot easier.
