Review on Pentek S1 20BB Pleated Cellulose Cartridge by John Floyd

Revainrating 2 out of 5

NOT only for chlorinated well water.

Product may be OK IF using chlorinated water but not recommended for well water. I could can't find it in the description to use it for chlorinated water only. I emailed PENTAIR and this was their response. the cellulose is treated as a nutrient. This causes the filter to break down and things to grow. Choose better a filter made of a more inert material such as polyester or polypropylene.

Pros
  • FITS ALL 20" Big Blue housings and can replace any 20" x 4.5" sediment filter
Cons
  • Something else
