Aquasana OptimH2O Reverse Osmosis Fluoride Review

Aquasana AQ RO 3 OptimH2O Reverse Fluoride ReviewThe Aquasana AQ-RO-3 OptimH2O reverse osmosis is a compact under sink filter system that will produce about 36 gallons of pure water per day. The actual amount of water that will be filtered per day is, like every other RO system, dependent on the inlet water pressure and the temperature of the water.

The AQ-RO-3 OptimH2O is advertised as a 3 stage filtration system which suggests it has less filtration than 7 or 5 stage filtration systems, but this is not the case. The AQ-RO-3 combines some of the features that other systems use 2 stages to carry out.

The system removes over 95% of fluoride and mercury along with 97% of chlorine and arsenic and 99% of lead and asbestos. The data sheet from Aquasana detailing all the contaminants removed can be found here

After the water has been filtered by the system, the water then goes through a final stage to re-mineralize it. This remineralization stops the water from having the RO ‘taste’ and makes it taste more like natural water. At the same time the pH value is raised. This raising of the pH value stops the water being slightly acidic to more neutral.

The AQ-RO-3 OptimH2O system comes with a 90 day satisfaction guarantee. If within the first 90 days of purchasing your system you are unhappy with any aspect of the system, Aquasana will refund the purchase price. In addition, there is also a 2-year warranty on defective parts or workmanship. NOTE – some sites suggest that the system has a 1 year warranty but when the details are checked out the unit has an Aquasana 2 year warranty, see here for details.

Filtration System Design

This system has a manifold to which the filter and membrane housings are attached. The remineralization unit is then attached to the side of the filter manifold. The system uses filter housings, that twist off and replaceable filter elements.

Water Efficiency

Every RO system produces an amount of waste water for every gallon of pure water that is produced. Typically, with most of the systems, this can be between 1 and 6 gallons of waste for every gallon of pure water that is produced. The waste water is used to flush impurities from the RO membrane and the amount wasted varies from system to system and the pressure of the inflowing water – the greater the pressure the less waste. Aquasana uses a different method for informing users of the efficiency of the system. In the documentation the system is said to be 17.91% efficient, in other words for every 5 gallons of water that are used just under 1 gallon of pure water is produced. This water efficiency also applies to kitchen faucets here.

Ease of Installation 4.2/5

The greatest difficulty with installing this system is in installing the outlet faucet if there is not an existing hole in the sink or work surface that you can utilize. With most RO systems only a ½ inch or 3/8 inch diameter hole is needed for the faucet. With the AQ-RO-3 OptimH2O with the chrome faucet, a hole of 1 ½ to 1 5/8 inch diameter is needed. This may present some problems for DIY installation.

If there is already an existing suitable hole for the faucet, the installation ice very straight forward and can be carried out by anyone with reasonable DIY experience. The manual is quite detailed and explains all the steps in great detail. Click the link for a copy of the AQ-RO-3 OptimH2O installation manual.

ProsAquasana OptimH2O Reverse Osmosis Fluoride Review

Water output per day – 36 gallons of pure water

Remineralization adds minerals back to the water to give a better taste and a less acidic water

3.2 gallon storage tank

High output faucet with 0.8 gallons per minute flow rate (when fed from storage tank)

Removes 95% of fluoride in the feed water

Carbon Pre-Filter & Claryum Post-Filter – Change every 6 months

RO Membrane Cartridge – Change every 12-36 months (depending on inflowing water pH value)

Remineralizer – Change every 12 months

US based technical support for the lifetime of the product

Cons

The main drawback with this system is the large diameter hole that is needed to mount the faucet. The 1 ½ to 1 5/8 inch diameter hole is too large for many DIY installers to drill without buying additional tools.

The rate at which the tank is replenished may mean that while the system can be used in an ice maker it may not be enough to supply a refrigerator drinking water outlet (if required)

Conclusion 4.5/5

During the AQ-RO-3 OptimH2O system review, many positive features were found. If fluoride is a concern of yours, the efficient fluoride removal will be a definite plus point for you. Add to that the fact that this is probably the least costly system that remineralizes your water to make it taste better and reduce the acidity of it. The manifold design of the system keeps the amount of flexible tubing that is used to a minimum. This makes the unit installation look tidier and lessen the risk of the tubes getting caught by anything else that you store under the sink. The complete unit is very competitively priced and provides good value for money. The only negative points are that the system has is the large diameter hole that is needed for the outlet faucet and there may be insufficient flow to feed a refrigerator water outlet (if required).

The negatives of the system, which may well not affect you, need to be weighed against the cost of having a system that produces mineralized water at the low cost of this system. The Home Master TMAFC Artesian system for example is producing mineralized water and has a greater output but costs about 80% more than the AQ-RO-3 OptimH2O.
