The THD-RO3-R consists of Carbon (Stage 1) and Claryum (Stage 3) filter cartridge replacements for the THD-RO-3 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
- Carbon and claryum filters (stage 1 and 3) should be replaced every 6 months or 365 Gal. 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
- Full system NSF certification, not just select components like tubing or tanks, Aquasana proudly displays the NSF logo for standards 42, 53, and 58
- Unlike other water filter certifications, full NSF certification requires extraction testing to ensure the system does not leach contaminants back into your water
- Removes up to 99% of contaminants including arsenic, chlorine, lead, fluoride, heavy metals, chloramines, mercury, asbestos, and more
- 1 year manufacturer’s warranty and toll-free lifetime support backed up by Aquasana water filtration specialists based in Texas (866) 662-6885

These filters really make a difference in my water quality and taste. It makes me feel good knowing my family and I are drinking clean great tasting water. Thanks

The water comes out so slow it takes forever to fill my kettle or any other large container. After I will my pot for boiling pasta it uses all the filtered water up and I have to wait a good 45 minutes for it to refill in order to have filtered water for anything else.

Had difficulty getting a referral for installer, had to find someone on my own. The filter works fine and is a very good value for the money. I do find the faucet has a very slow pour so it takes a while to fill a pitcher of water. The water does taste much better though. I would recommend the product.

As easy to use as practical

Hi. We installed the filters and noticed different, softer water taste so we wanted more crunch and add calcium to pitchers. We’ll get the right proportion eventually. What about annual mineralization refills? They should come with every second delivery. What about trace minerals and a nitrate/nitritre test with annual delivery?

This is for everyday drinking and cooking. The water quality on Long Island is horrible and this not only removes virtually all the contaminants but it tastes great with having the reverse osmosis included.

I love my water filter. The water tastes great and my pets like it too. I can also use the water in my steam mop and humidifier without leaving a residue.

When installing filters keep towels handy because it will leak during removal. After the filter is placed in the housing be very careful not to over tighten because it will leak like crazy.

There was such a difference in the old and new. Changing was fine.

A very good filtering solution as long as you don’t need constant flow. The bladder tank provides a pretty decent flow for up to about a gallon of water. After that the flow tapers off severely and you need to wait for the filtering system to fill the tank back to top pressure for good flow again. I find it adequate to our needs.

Excellent taste and good for health.

I am afraid of tap water and water bottled in plastic. If I have to move, I will be buying a system for my new living space.
Chris Rice (verified owner) –
The unit works well but I wish it had more pressure. ALSO, the replacement filters don’t come with instructions and there are none on their website. It would be a big help if they did
