You no longer have to buy bottled water to get bottled water quality.
With the AP-4.0 you will have safer, better tasting water without the taste and odor of chlorine, always available at your sink top or even your refrigerator ice maker or water dispenser (we include the fittings to connect it your refrigerator) Your coffee, teas and mixed drinks will taste better, ice cubes will be clearer, and little or no scale build-up will occur in your coffee maker.


If you buy bottled water from the “pure high mountain springs”, you are paying for the fuel for the trucks to bring it to you. These gasoline or diesel fueled engines pollute the atmosphere while doing this, and then you must dispose of the plastic containers at the landfill. For 12¢ a gallon the PureWaterMachine™ converts city water to the good tasting pure water you desire without paying to pollute.
      How it works.
The AllPure reverse osmosis filter AP-4.0, has been specifically designed and optimized for your household drinking and cooking water needs. It uses the city water already available at your sink to operate (the Reverse Osmosis process). 4 different filtering technologies are included to give you the freshest, best tasting water right from your sink top. The compact unit easily fits under your sink, the large high capacity RO membrane (capable of up to 36 gal/day water production) ensures little or no waiting for the tank to re-fill. And the automatic shut-off valve conserves water by shutting the unit off when the tank is full.
      Stage 1
Sediment Filter
The 5 micron Poly Filter takes out suspended solids such as dirt, rust, sand, and pipe scale.

Stage 2
Carbon Filter
The 5-micron activated carbon block filter removes chlorine, bad tastes and odors.

Stage 3
Reverse Osmosis
The 36-gallon per day Reverse Osmosis Membrane removes dissolved solids such as lead, chromium and nitrates.

Stage 4
Post Filter
After purification the water is stored in a 4.0 gal. tank. When the faucet is opened, this purified water goes thru a granular activated final filter.
