The 3-stage H2O+ Cypress H630 water filtration system:*

 Stage 1: COMPOSITE PLUS FILTER (HF-31): This 2-step filter reduces particulate materials such as sand, rust, and fine particles from the water supply. This first filter also acts as a pre-filter protecting the 2 following filters. Recommended replacement every 6 months.

Stage 2: NANOTRAP FILTER (HF-32): This specialized, patented, innovative Nanotechnology filter is made with 100% USA sourced materials including Nano alumina & cellulose fibers with a pore size of 2 micron (2 µm) that reduce turbidity, harmful waterborne microorganisms (including many bacteria and virus) as well as numerous particulates. Recommended replacement every 12 months.

Stage 3: CARBON BLOCK FILTER (HF-33): As the final stage in the filtration process, the Carbon Block filter further reduces particulates, bad tastes and odors, and water contaminants such as chlorine and volatile organic compounds (VOC’s), improving the taste of the dispensed water. Recommended replacement every 6 months.
