About this product
Keep your whole house system performing at its best with a fresh set of cartridges. This kit contains the same three 20 × 4.5 inch cartridges supplied with the Elite Filtration triple-stage system, and fits any standard 20 × 4.5 inch filter housing.
Replace all three cartridges every 12 months — or as often as every 6 months with poor water quality or heavy use. Replacing them every 12 months is also a condition of the triple-stage system’s warranty.
Filtration stages
-
Stage 1: 5 micron pleated sediment filter — reduces sediment, dirt, rust and debris, protecting the stages that follow and your appliances.
-
Stage 2: 1 micron coconut carbon (CTO) filter with scale reduction — reduces chlorine taste and odour, and scale build-up.
-
Stage 3: 1 micron coconut carbon (CTO) filter — high-absorption coconut carbon (1100–1200 iodine value) that further reduces chlorine, chloramine and chemical residues.
