This filter medium made of polymer fibers favorably replaces the sand, glass or zeolite in the sand filter. It is a new material that filters water without additives or additional chemicals.
PureFlow® is of textile origin: it consists of compacted fibers of various types and thicknesses. Fiber thickness and density is calculated based on usage.
Ultra light, 320g of PureFlow replaces 25kg of sand! It allows filtration at 10 µm, does not create a biofilm, reduces backwashing and limits the pressure in the filter.
