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.

I am very happy with my water filter. Water is delicious... and it is always available.The set up process was a little bit long, but worth it. The initial visit with Armand was pleasant and professional.The installation turned out to be faulty- the filter stopped working the next day and there was a leak. However, when I called, the team came to fix it and I haven't had any problems since. Overall I am very pleased with my decision to install the filter with LI Clean Water more
LEARN FROM MY MISTAKE!!!!! If you’re looking for a home... water system you’re in the right place. Long Island Clean Water is the right choice! It can be really tough figuring out what company to go with - I was in your spot once and faced a huge amount of stress, health issues and plumbing difficulties because I chose the wrong company at first. I originally chose the pHountain and boy was that a huge a MISTAKE! They had a great sales pitch but at the end of the day that’s all they had. I could go on about how bad my experience was with the pHountain and their terrible quality of water and customer support but I will save you the time and negativity. Just go with Long Island Clean Water. You won’t be disappointed. Anything we need they are right there and always professional and kind. They are a wonderful business with a wonderful team and I’m grateful to have found more
We are new, highly satisfied customers of LICW. They are... extremely professional and reliable with wonderful customer service. Their team goes above and beyond and truly cares about their customers and people's well being.We originally had a whole house water filtration system installed by pHountain and it was a complete disaster. We were scammed by the owner, Eric, who continued to refuse to help us.After starting fresh with LICW we realized what our experience should have been like. The whole team was there every step of the way to make sure we had everything we needed and Christian and Reynaldo did a great job installing our new system.If you are looking for clean water and feeling lost, save time and just contact more
LICWS was extremely professional, helpful, and patient. We... worked with Armand, and he took the time to explain our local water report, test our water, and make a recommendation for us, clearly explaining everything throughout the process. He even took my calls to answer my questions at all hours of the day. Thank you!Install was set up quickly, and the installation team was polite, efficient, professional, and also took the time to explain how everything worked, and to answer all of my questions. They even left their phone numbers in case any future questions arise. Overall a great experience. Thank you more
