Rainfresh P2S Siphon Water Filter

Rainfresh P2S Siphon water filter comprises of an Envirogard 7300G silver-impregnated ceramic filter with tubing attached, two separate 35 liter water containers, one for the untreated water and the other for safe drinking water. Untreated water is poured in one of the containers which is then placed at a vertical height of higher than 1 meter. The second container is placed at the ground level. The ceramic filter is placed in the dirty water container with the tube running down to the empty container. Suction is applied to the end of the tube and water slowly passes through the ceramic filter to create a siphon and safe drinking water drips into the empty container at a max flow rate of 4.6 liters per hour. The included scrub pad and filter gauge are for cleaning the filter and measuring end-of-life.

Available during distributions from the partner NGO or by contacting the manufacturer.

The Envirogard 7300G silver-impregnated ceramic filter cartridge must be replaced after filtering 3,875 L or within 6 to 12 months. The filter gauge is used after cleanings to measure wear on the ceramic filter and indicates end-of-life.

The Envirogard 7300G filter cartridges are tested and certified by CSA International to NSF53 for 3 log reduction of protozoan cysts (such as cryptosporidium & Giardia).
The University of Arizona also found 6 log removal of bacteria including: E. coli, Salmonella typhimurium (typhoid), Vibrio Cholera, and Shigella (cause of dysentery) under very low turbidity conditions of <0.5 NTU.

No known safety risks if properly used and bottom bucket remains properly sealed against recontamination.
