Under Counter Reverse Osmosis Water Filtration System

Product Features

While most reverse osmosis systems use a 10 or 12 gallon per day membrane, we use a 75 or 150 gallon per day. Why? While 12 gallons per day sounds like plenty of water, it's the production time you need to consider: it takes the 12 gallon per day (gpd) membrane over 2 hours to make one gallon of water, while it takes our 75 gpd membrane about 20 minutes to make one gallon and the 150 gpd membrane only 10 minutes (at 65 psi and 77° F)! Most storage tanks only hold about 2 gallons of water, so you can see that during heavy use times (company) you could be out of water for some time with a slow membrane!


R/O systems are not created equal - here’s what makes our 4-stage system a great choice:

  • 75 or 150 gallon per day GE Osmonics® TFC encapsulated membrane (NSF-58 certified) - for fastest recovery time and high removal rates: 20 minutes for one gallon at 96% for 75 gpd, 10 minutes per gallon at 93% for 150 gpd (@ 65 psi and 77º F).
  • 1 micron GE Osmonics® sediment pre-filter (NSF listed) - removes sediment, rust, silt. Most competitors use a 5 micron.
  • High performance Omnipure® KDF® carbon block pre-filter (NSF listed) - removes chlorine, bad tastes and chemicals. 3 oz. of KDF-55® media is "Aquabonded"® to provide a high capacity (20,000 gallons) that eliminates the need for an extra carbon filter stage. The KDF® also helps protect the membrane from bacterial contamination and degradation.
  • Omnipure® coconut shell granular activated carbon post filter (NSF listed) - final polisher.
  • Slim, space-saving 4 gallon (*) NSF listed plastic storage tank - large capacity but compact, no metal to dent, rust or corrode.
  • Automatic shut-off - shuts off water when tank is full, saving water.
  • Long reach LEAD-FREE chrome-plated brass faucet with stainless steel valve (complies with NSF-61 and California Prop. 65 standard).
  • EZ Faucet Connector instead of typical saddle valve - improved flow, no permanent line damage.
  • Choose between a traditional drain saddle or new disposal drain adapter for a trouble-free connection.
  • GA Murdock® NSF® certified quick-connect fittings make installation a snap - rated at 150 psi at 70º
  • GA Murdock® NSF® certified polyethylene tubing - rated at 230 psi at 70º.
  • Quick-connect tee fitting included to connect refrigerator ice-maker
* - Total tank volume, based on industry-standard rating. Actual capacity of any bladder-type storage tank is less than the rated volume. At 60 psi, it is 60% of total; at 50 psi, it is 50% of total; at 40 psi, it is 40% of total.

Reverse osmosis system space requirements: Main unit is 18" tall x 14" wide x 6" deep, storage tank is 9" diameter X 20" tall (a 3' tube connects them - they can be on opposite sides under your cabinet). 5 year warranty on hardware, 2 years prorated on membrane.
