Reverse Osmosis Drinking Water Systems

American Aqua System ERO 175

American Aqua offers a variety of installed drinking water systems designed to remove contaminants from the water your family drinks. Installed drinking water systems can be tucked away under the kitchen counter or in the basement.

The perfect complement to an American Aqua water refiner or water softener for the water-conscious family is a reverse osmosis drinking water system. Our exclusive line of reverse osmosis water purifier systems are specifically designed to provide clean, clear, better-tasting drinking water by removing more than 95% of dissolved solids including many harmful contaminants. Now you can have bottle-quality water at your tap.

With an American Aqua RO system you get:

  • Three or four-stage water filtration.
  • Semi-permeable membranes to reject solids.
  • Specially formulated pre-and post-filters to reduce contaminants, eliminate odors, and improve taste.
  • Automatic shut-off to conserve water.
  • Optional electronic monitor to alert you when filters need changing.
  • Space-saving designs.

Here is how a Reverse Osmosis Drinking Water Purifier works:

  1. Household water is directed through a pre-filter for filtration to remove sediment, chlorine taste and odor and particulate matter.
  2. The water is then forced, by pressure, through a semi-permeable membrane where a high percentage of the dissolved solids and other contaminants are rejected and flushed to the drain.
  3. A final polishing of the water is accomplished by an activated carbon absorption block filter removing tastes and odors. The water passes through this final filtering process immediately before going to the faucet whether it comes direct from the unit or from the storage tank.
  4. The automatic shut-off control shuts down the system when the storage tank is filled and water is not being drawn. This “demand production” feature conserves water by eliminating the constant running to the drain found in some units. The control also depressurizes the membrane when not in service extending the membrane life and reducing the need for maintenance of your reverse osmosis water purifier.

American Aqua offers a broad range of reverse osmosis purification systems including the ERO R375, a state-of-the-art reverse osmosis filter. These products reduce substances such as chlorine taste, sediment, nitrates, lead, cysts and detergents.

100% satisfied. We are new to water softeners and had many questions and concerns. So we scheduled an appt with American Aqua. The customer service rep on the phone was very polite and friendly. She... made us an appt for the next business day! (I was expecting a couple weeks at least.) The technician arrived on time and he too was very friendly. He examined our system, made a few tweaks, tested our water, explained in detail what we as consumers needed to do to maintain the system. He patiently answered all our questions and patiently repeated what we didn't understand the first time around. Then, as a parting gesture of good will, he kindly told us to bring a sample of water to their office if we ever have concerns in the future and they will test it free of charge. An overall great experience. A++ to CJ the technician and to American Aqua. I highly recommend more
