What am I missing here? Filter prices

[GMTK]

Found these online: PA137 Unicel C-7490 Hayward C-5500 CX1380RE Filter - $49.76

They are about half the price from "normal" unicel filters I am looking at buying.

May want to look into these on Amazon. Optimum Pool Technologies makes/markets some very good products for the same price. Not sure why All Filters would recommend replacement every 12-18 months unless that's all the life you would get. With proper care a set of cartridges can last a decade.
