NSF Certified to reduce 97.6% of chlorine as well as over 50 other contaminants. Long filter life lasts up to 625 gallons. Little maintenance required. Very high system and replacement prices.


The Aqua-Pure® Drinking Water System AP-DWS1000 reduces chlorine taste and odor, particulate, lead, VOCs, parasitic protozoan cysts, and MTBE from drinking water. The water filter system uses advanced dual-stage carbon-block filtration, providing tasty, clear water and protecting plumbing and fixtures.

The Aqua-Pure system uses an exclusive progressive porosity process, filtering water through increasingly tighter pores to help reduce microscopic particulate. It has a nominal filtration rating of 0.5 microns and operates at temperatures up to 100° F/37.8° C and water pressures up to 125 psi/862 kPa. The system has a flow rate of 0.6 gpm/2.3 Lpm and capacity of 625 gal/2,366 L.

Automatic shutoff ensures quick and easy filter changes:
The Aqua-Pure AP-DWS1000 is designed with a built-in shut-off meter that automatically shuts off the system after 625 gallons/2,366 liters of water have been filtered. To change cartridges, simply twist off the old cartridge and twist on a new one—no tools required and no contact with soiled material.

Improving your home's water quality.
Used to help improve water quality in food service operations, businesses and homes, drinking water filtration systems range from complex multi-filter systems at the point where water enters the house, to simple plug-in under sink units easily installed on the water line. Costs vary, but a carefully chosen water filtration system can pay off by replacing bottled water purchases and preserving fixtures and plumbing.

“After putting it off for a week because I really, really hate plumbing jobs of any kind ... I finally hauled off and tackled this installation under the kitchen sink. ”
