Hague's 5 stage Reverse Osmosis Systems are built and backed by the Hague philosophy which holds that "Quality is our Company's Most Important Asset."

Hague uses no toxic glues. All plastic parts are threaded or sonic welded. Our 5 Stage Reverse Osmosis System has 50% - 70% more carbon than most conventional 3 or 4 stage systems.

Stage 1: Reduces sediment down to 5 microns - 8 times smaller than the human eye can see.

Stage 2: The carbon prefilter reduces chlorine and organics, improving tastes and odor.

Stage 3: The membrane filtration reduces total dissolved solids down to 200 molecular weight. The pores on the membrane are about 1/100,000,000 of an inch. You would need a scanning microscope to see the total dissolved solids that are filtered.

Stage 4: Chemical removal filter, slow flow rate, and high contact maximizes this filters ability to reduce hard to remove organic compounds.

Stage 5: The carbon post filter improves tastes and gives your water a final polishing after leaving the storage tank and before coming out of the faucet.
