PCC80-PAK4 Replacement Pool Filter Cartridge for PCC80, C-7470,PLFPCC80, Darlly 70804,Clean and Clear Plus 320, Filbur FC-1976, 20"x7" Pool Filter, 4 Pack

I clean the filters every 3 months and they last a good while, about 2-3 years

Reasonable price and good quality

Bought these filters as fill-in replacements and they did not last but 3-months...had to toss, all other filters last me a minimum of one-year, cleaning once/quarter. I am done buying replacements.

Least expensive cartridges and fits and operates as well or better than original cartridges!
