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.

I am super impressed with Adam from American Aqua. I work in an industry where I encounter plumbers on a daily basis, but I've never met a plumber like Adam. Getting our water softener installed was... a month-long ordeal for a variety of outside reasons, none of which were the fault of American Aqua. Adam was beyond patient and kind, answered questions, and he clearly takes pride in his work. I'll be recommending him to anyone I can from here on out. I just can't say enough good things. The guy is more

Would recommend them to anyone looking for softening and filtering equipment/ more

The gentlemen (CJ M and Percy O) rom American Aqua that rebedded our water filtering tanks were great! They called before they came and arrived on time. They were extremely knowledgeable and... professional about what they were doing. They were careful about leaving everything clean and the work fully completed. We have had the pleasure of working with this company for years and will continue to do so. 5 out of 5 ratingCarol V.Today we had another routine service that was completed by Dylan Keller. We would give him a 5 out of 5 Rating. It is obvious that he likes helping people and cares about doing the best job possible. He also brought salt, filled the tank and carefully explained the difference in between a couple different kinds of salt.This is a great company and everything is always done well beginning with the first welcoming hello”. from the office staff. Thank you.Carol more
