The perfect complement to a WaterCare 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 WaterCare 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.

Certain Services, Inc. offers a broad range of reverse osmosis purification systems. These products reduce substances such as chlorine taste, sediment, nitrates, lead, cysts, and detergents.

"Hey Bill & Chris! Regarding our service call yesterday, our overall experience was awesome. A personal call for service, with a technician arriving quickly! Nick was very friendly, thorough and professional. Very quick with his diagnostics and repair. And, very reasonably priced! Every experience we’ve had with the Certain folks has been incredible, but each time you seem to go above and beyond the last. And, most importantly… perfect water!! Thank-you!" - Steve Donaldson

Frequently Asked Reverse Osmosis Questions:

What is reverse osmosis?

Reverse Osmosis (RO) is a water purification process that uses a partially permeable membrane to remove unwanted molecules and particles from drinking water.

What does reverse osmosis remove?

Reverse Osmosis removes common chemical contaminants such as:

  • sodium
  • chloride
  • copper
  • chromium
  • lead

Some systems may also reduce:

  • arsenic
  • fluoride
  • radium
  • sulfate
  • calcium
  • magnesium
  • potassium
  • nitrate
  • phosphorous

How much is reverse osmosis system?

A Reverse Osmosis System cost depends on the type of system you’re looking to purchase. Under sink reverse osmosis systems range from $250 to $7,500. Whole house reverse osmosis systems range from $1,000 – $18,000. System costs depend on a number of factors but are most closely tied to the amount of water that needs to be filtered per day.

How to remineralize water after reverse osmosis?

You can remineralize water after reverse osmosis filtering through various methods. Most modern reverse osmosis systems include a remineralization tank that takes care of adding minerals back into your water for you.

How to make reverse osmosis water alkaline?

You can make reverse osmosis water alkaline by adding alkaline minerals and raising the ph of your filtered water.

What is not removed by reverse osmosis?

What is not removed by reverse osmosis may surprise some. While RO filters will reduce a wide range of contaminants from your water, it will not remove some pesticides, solvents, volatile organic chemicals VOCs (like chlorine and radon), dissolved gases (ammonia, carbon dioxide, oxygen, hydrogen sulfide), and organic contaminants (such as formaldehyde, methanol, acetonitrile, methyl ethyl ketone, etc.).

How much water does reverse osmosis waste?

Reverse osmosis wastes on average about 4 gallons of water per gallon made. If you use 3 gallons a day for drinking, cooking and internal consumption, that means you will waste about 12 gallons, making a reverse osmosis system about 25% efficient. Comparatively, a washing machine and dishwasher use electricity and hot water (which takes energy to heat) and waste every gallon of water they use.
