Countertop Reverse Osmosis Units

Our countertop RO units use the same membranes and filters as our larger undersink units and produce water of the same high quality. We’ll build to your specifications after talking with you, or you can order one of our standard models listed below. We build two basic styles and are open to suggestion if you have special requirements.

“Countertop” means more than that the unit sits on the kitchen cabinet. It refers to a style of reverse osmosis unit that produces directly into a container and does not have the pressurized storage tank used on undersink reverse osmosis units. This allows for the omission of several standard undersink reverse osmosis parts, like automatic shutoff systems and check valves. The design is simpler and the unit is less expensive.

Countertop reverse osmosis is in many ways the greatest bargain in purified water. You get more water for your money than with undersink reverse osmosis systems because with countertop units the storage tank, the ledge faucet, and several small internal parts are not needed. The price you pay is convenience. Undersink units produce and store water automatically, but with countertop reverse osmosis units you have to work a little for the water.

These systems are designed to provide top quality water for customers who don’t want to install an undersink system. They aren’t for people with a low tolerance for inconvenience.

These units are designed to function mainly as bottle fillers. The unit will fill a five-gallon bottle with top quality drinking water while you sleep or watch TV, then you put the RO unit away until you want to fill another bottle. It’s also a favorite among specialty users, like greenhouse and aquarium owners. It can be used in the kitchen, the laundry room, in a motor home—anywhere there’s a water source and a drain. We even have a garden hose or outdoor faucet attachment if you’d like to put it on the patio.

Water quality with countertops is the same as with undersink units—sometimes a little better-- because the unit doesn’t have to work against the pressure of the storage tank.

We’ll build it with full-sized vessels (as in the picture below), space saver vessels (like the vessel used for the countertop filter in this picture), inline vessels (like the Style B unit below), or Q Series convenience vessels—as you wish.

Most of our customers choose one of the two basic styles below, which you can order from the shopping cart. But if you want something different, please call.

Style A.

Part #	Description	Price
RO200	Style A Full-Sized Countertop Unit	$197
Special Considerations
Standard production is 50 gallons per day. Approximate Annual Upkeep: Less than $40 for filters with an additional $55 membrane every three years or so.
Dimension
Dimensions: 5.5" deep, 18" tall, 14.5" wide.

Full-sized system. This unit is identical to our Black & White undersink units, except it’s styled to operate as a countertop.

Water enters the black vessel, passes through a carbon block filter, then goes to the reverse osmosis membrane (white horizontal vessel), then another carbon block filter (white vertical vessel).

This unit can stand free, as shown, lie on its back, or be hung on a wall. It uses standard MatriKX carbon block 10-inch filter cartridges and a 50 gallon-per-day Filmtec membrane. We can alter the production upon request. (Vessel colors are negotiable. If you want all white, for example, let us know. Clear vessels—vertical only—are also available upon request at no increase in price.)

The two carbon block filters should be changed annually and the membrane approximately every third year. If you own a TDS Tester (see below), you can usually save money on membrane changes.

Annual upkeep without membrane is less than $40 for the two carbon block cartridges.

Standard cartridges for this unit are MatriKX CTO prefilter (black housing) and MatriKX +1 post filter (white housing). Other cartridges can be substituted upon request. Cartridges at www.pwgazette.com/filter01.htm fit this unit.

Style B.

Part #	Description	Price
RO201	Style B. Inline Countertop Unit	$197
Special Considerations
Standard Membrane is a 50 GPD Filmtec. This unit comes with one extra filter cartridge. We recommend changing the prefilter twice a year and the post filter once a year. We offer a 10% discount on the single cartridge price when a year’s worth of replacements are bought as a three-pack. Approximate Annual Upkeep: $40 for filters with an additional $55 membrane every three years.
Dimension
Dimensions: 6" deep, 6" tall, 14" long.

This compact system features Omnipure K Series inline filters with John Guest quick-connect fittings for easy maintenance. It's very easy to use, easy to service. Water enters a granular carbon filter, passes through the reverse osmosis membrane (top vessel), and exits through a second K Series carbon filter.

Fifty gallon-per-day production is standard, but we can make it produce more on request. Like Style A, the standard membrane is a Filmtec 50 gallon per day TFC.

Suggested Cartridges
