Reverse Osmosis Aquamaster AMR4000P


  • 60760

Model #: AMR4000P

Same advanced 5-stage reverse-osmosis technology as the AMR4000P with the added benefits of a permeate pump that regulates production of treated water to keep the rejection water the minimum level. Water production and rejection rates vary based on water temperature, pressure and the level of total dissolved solids in the water. In our cold climate, a permeate pump effectively neutralize the effect of colder water keeping the rejection rate constant and at its optimum level. 

Enjoy The Many Benefits:

  • Great tasting, healthier water for drinking and cooking
  • Crystal clear ice cubes
  • Flavourful coffee, tea and juices
  • Ideal for baby formulas
  • Tasty Pasta and soups
  • Great for pet and plant water
  • The best way to enjoy the 8-10 daily glasses of water recommended by nutritionists
  • No heavy cooler bottles to lift


Aquamaster purification systems employ high capacity filters and membranes certified by the National Sanitation Foundation (NSF). Once installed, there's practically nothing to worry about.

Unlike other systems, AquaMaster's filter cartridges can be replaced in a matter of seconds with the twist of a wrist. No tools are required. You don't have to worry about "contaminating" the filter. And you don't have to fiddle with small, easy-to-damage (or misplace) parts like O-rings.


All models are engineered to fit neatly out of sight under your kitchen sink. or they can be installed in your basement or another convenient location.
