Superior 4-Stage filtration process includes the following;

Stage 1 - 5 micron Sediment Filter - First of all, the sediment filter is at removing sand, silt, rust, and pipe turbidity. (replace every 6 months)

Stage 2 - 1 micron Granular Activated Carbon (GAC) Filter - Next, GAC is king when it comes to cleaning municipal water. Specifically, carbon media reduces chlorine, benzene, pesticides, and insecticides.  The carbon materials used in this filter are of the highest quality and are NSF certified. (replace every 6 months)

Option 1 - Stage 3 - 100 GPD RO Membrane -  Reverse Osmosis works by pushing water through a semi-permeable membrane at extremely high pressure. As a result, the water is crystal clear and free from impurities found in municipal water sources including salt, iron, fluoride, lead, bacteria & pharmaceuticals. Radio-active materials cannot withstand advanced filtration technology. Replace RO membranes every 24 months.

IMPORTANT - Coolers equipped with Reverse Osmosis require an outlet drain. The hot and cold tanks in bottleless water coolers with RO filtration take approximately 1-1/2 - 2 hours to fill from empty.

Option 2 - Stage 3 - Ultra-Filtration - Much like RO, the UF membrane will provide “absolute filtration”. It will even eliminate bacteria and viruses. UF is the best choice to remove heavy metals, and toxic particles, all while leaving “healthy” minerals such as salt, calcium, and magnesium behind. Replace the UF Membrane every 4-6 months.  NOTE:  This option does NOT require a drain.

Stage 4 - 0.5 micron Carbon Block Filter - Finally, carbon block technology removes 99% of chlorine, lead, and microbial cysts. In addition, carbon block removes bad tastes & odors, and provides delicious, and fresh tasting water. (replace every 6 months)

Optional UV Sanitizing

The FDA approves UV in POU water systems because ultraviolet light kills 99.9% of harmful bacteria. At 254 nm UV energy kills 99.9% of various microorganisms.  A quartz sleeve encases the UV lamp. As water flows through the chamber its exposed to UV.

NOTE -  If you have well water in a rural area, or live in a town or village that has uncertain chlorination, then the UV stage is recommended.  If your water is being supplied from a well or spring you should consider Ultraviolet. Or, if you're not sure that your municipality is sufficiently chlorinating the water supply, you may want to consider adding UV as a final stage in your purification process.

Q: Hello. We recently purchased and received a H20-2500 and was looking to hook up a Keurig after the 4-stage filtration. Will running a second water line off after the 4th filter cause any problems or issues? Best regards, John
— Asked by John Walker on October 25, 2017
A: Yes... you can t-off the line and run purified water to a coffee maker without any issue.
