Guardian Filtration Products Pool Filter Cartridge 719-168-04 Four-Pack Replacement for Pleatco PCC80, Unicel C-7470, Filbur FC-1976, Pentair, Pac Fab, American Products

These fit my Chrystal water pool filter perfectly. You do not realize how badly the old filters have degraded until you put in new ones and wow the pool is sparkling. These were very reasonably priced. I don't know how long these will last but they are working great for the first six months. These were much less expensive than going thru my pool man or the local pool supply store.

Exactly perfect fit. Does a really good job of pulling the particles out of the water. If you have a lot of crap in your pool, the filter may plug quicker because it does such a great job of filtering but you don't have to throw them away. You can just rinse them out and reuse them. I like it. Good value for the money

I've bought these a few times. What I was looking for was quality filters at a reasonable price. Good enough to filter the water, but cheap enough that I felt OK replacing them every year. I know that supposedly you only have to replace cartridges every two years, but I have found the entire pool works better if I replace them every year.

Quality will need to be time tested for honest review

Bought this for my Pentair filter. They are perfect and a lot cheaper than local pool stores.

Works great, replaced my filters for a fraction of the cost!

I have used these filter for 3 years and 8 months and am replacing next month.. solid product...

This things are off very poor qualityThe dirt algae cycle it does stays in the filter like my old ones

Will provide good filtration for my pool.

The horizontal bands start peeling off instantly

Decent filters but had to pay $60 in duty and brokerage which undermined the savings. I will go with pleatco in future. The quality is marginally better, and as a bonus, no surprises in shipping.
