Tier1 5 Stage Under Sink Reverse Osmosis Home Drinking Water Filtration System 50 GPD

Save 20% (MSRP: $249.99)



The Tier1 5-Stage Reverse Osmosis System is the complete package, using 5 stages to deliver up to 50 gallons of filtered water per day. The 5 stages include a first stage sediment filter, to remove particular contaminants, followed by a carbon filter for bad taste and odor, and a third stage sediment filter to remove any remaining contaminants, prolonging the health and performance of your system. The 4th stage is our Tier1 RO membrane which removes 99% of all Total Dissolved Solids, and lastly an inline carbon block filter to polish the water. Once processed, the water is transferred to an automatic shutoff valve equipped storage tank where it waits for you to turn on the tap! This system includes all of necessary parts: starting filters, membranes, housings, brackets, shut-off valve, saddle valves, tubing, fittings, standard long reach chrome faucet, and installation instructions.

Key Features

  • For optimum performance, change the sediment and carbon filters every 6 months, depending on use. The membrane should last 2-3 years.
  • Per glass, the RO5 gives you better water and costs you less than your average bottled water.
  • RO membranes capture contaminants like barium, cadmium, chromium, copper, fluoride, lead, mercury, nitrates, radium, and TDS.
  • Modern design chrome faucet included!
