Pool filter cartridges can run for about 2,000 hours for a filter pump. Usually filter cartridges have to be replaced once every 1 or 2 years. The life of the filter will be less if you enter the pool with suntan lotion, deodorants, mousse, styling gels, and other damaging chemicals.

Oversized filters are good, but oversized pumps can cause filter problems. Read on for more information on DE Filters, Cartridge Filters and Sand Filters, click the links below.
