Guardian Filtration ProductsPool 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.

I ordered the incorrect size filters, and the return process and re-ordering was very easy.

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

These filters fit the bill for our pool pump and come without a lot of packaging. We need to figure out a way to recycle the hard plastic frame and replace the filter material for a more eco-friendly product. I cringe to think after the life of the filter these dolls sitting for a thousands years in a land fill.
