Transform Your Water with a Reverse Osmosis Drinking Water System…

And Create Delicious, Healthy Water Free of up to 99% of Common Contaminants Found In Our Local Water.

Long Island Clean Water Service, Inc. 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 EcoWater System water refiner or water softener for the water-conscious family is an EcoWater 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 EcoWater Reverse Osmosis System You Get:

  • Semi-permeable membranes to reject solids
  • Three or four-stage water filtration
  • 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’s How Reverse Osmosis 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. 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 directly 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.

EcoWater Systems offers a broad range of reverse osmosis purification systems including the ERO 385, a state-of-the-art reverse osmosis filter. These products reduce substances such as chlorine taste, sediment, nitrates, lead, cysts, and detergents.

Everyone who came to my home for the install and then... subsequent hook up were prompt, professional and helpful. They answered questions and all seemed very well trained. Couldn’t be happier. Love my new water and ice cubes, especially. Now, when I fall asleep with a glass of ice water on my nightstand, I can drink it in the morning and it doesn’t taste terrible. Very grateful. Also, being that my plumbing situation was somewhat problematic, I appreciate all the help I received on the phone the many times I called. I spoke to Madelyn herself and also other employees. Everyone was polite, friendly, patient, and helpful. Terrific company. Well done. I know I made the right choice.read more

We've had LI Clean Water drinking water filters in our... house for several years now. The water tastes good. For the first year or so they kept getting clogged, but LI Clean Water Service always came very quickly to fix the clog and if it was between the annual replacements, they did it for free. They eventually figured out what was wrong with our water and changed things so that it wouldn't get clogged like that any more. In general I find everyone in the company really pleasant to work with. Great company to do business with.read more
