These filters work like a charm. The flow is excellent while the filtration leaves a super clean pool. Living in the Southwest, sand dust is present everywhere. These filters catch this easily. And the price is great. You will pay most three times as much at your local Leslie’s pool store.

2nd but. Last ones still ok after 3 years. Now I have a back up

The best place to go for pool filters! I’m a constant repeat customer! Quality matters at the best prices.

Excellent product, going on over a year now and these are as good if not better than the originals. I've tried my luck with various other off-brand versions and none have the quality or cleaning effectiveness as these. They fit great with no issues. They clean up really well too and basically work like new every time I give them a good rinse with the hose. They are keeping the pool super clean. The filter material is really nice and the plastic bands do a good job of keeping them evenly spaced out just right so the water flow is not inhibited. I haven't had any issues with these, and the price is just right. Way cheaper than going with the Pentairs. Be careful of other random brands though, they are not all that great. Happy to have given these a chance because they are totally worth it.

These filters appear to be exactly as advertised along with fair pricing. I cannot comment on the longevity as I have only had them a couple months.

!!Important!!MADE IN THE USA!!!Exactly as described, perfect fit!

Good filters have had for 4 months. Easy cleaning. Much less expensive that purchasing at local pool store.

Fits my Pentair pool system
