Kleenwater 2.5" (W) x 20" (L) Hot Water Protector Water Filter for Scale Prevention and Corrosion Protection
-Protects tankless hot water systems and helps avoid costly service calls
-Polyphosphate filter to prevent scale and reduce the harmful effects of water hardness
-5 micron dirt rust sediment filtration
-Creates a thin glass-like layer to provide corrosion protection
This filter cartridge kit is the replacement for our Kleenwater KW2520-scale-X System and for other hot water protector systems that require a 2.5" (W) x 20" (L) replacement filter.
The water filter cartridges are made of food grade wound cotton that filters sediment to 5 microns. However, the critical feature that provides the essential protection to tankless systems is the phosphate ingredient. This ingredient reacts with naturally occurring calcium bicarbonates in the water supply to form a thin, tight, non-corrosive, passivating film on pipe walls. This film is almost like a glass coating, separating the water from the metal plumbing/hot water system.
This system will prevent scale build up and reduces the harmful effects of water hardness. Pre-filtration is required to prevent damage to expensive tankless systems and help to avoid costly maintenance calls.
This item consists of (2) 9.75" filters and (1) 1/2" coupler which creates the 20" length required.
