3 Stage Filtration or 4 Stage Reverse Osmosis Filtration Technology

Stage 1 – 5 Micron Sediment Filter

The first stage is a 5 micron Sediment filter that helps improve Sediment such as sand, rust and silt that is present in most municipal water sources.

Stage 2 – 1 Micron Granulated Activated Carbon Filter

The second stage of filtration is a 2 micron, granulated activated Carbon filter. This filter uses an advanced Carbon technology that has been certified by the NSF to remove hundreds of cancer-causing constituents such as pesticides, insecticides, petrochemicals, M.T.B.E’s, PCB’s, defoliants, and benzene.

Stage 3 – Reverse Osmosis Technology

The 3rd stage utilizes Reverse Osmosis technology, which removes any molecular compounds smaller in size than water molecules. Such compounds include salt, manganese, iron, fluoride, lead, and calcium.

Stage 4 – 0.5 Micron Carbon Block Filter

The 4th and final stage is a 0.5 micron Carbon block filter, which gives the water a final “polish”. It removes 99% of lead and microbial cysts such as giardia and cryptosporidium. It also ensures that all chlorine has been removed, and that the water entering the holding tanks is completely odorless.


Simple and easy to use control panel, featuring a well-designed 45° angle for easy and convenient use.

Large 10 inch dispensing gap featuring a blue LED light which offers an elegant touch to any setting.

Filter assembly is front panel accessible.
**Filter life 2500 gallons or every 6 months.
