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.

Perfect replacement for the CP420. Appears to be of good quality and perfectly fit in the filter housing.Just installed so cannot comment yet on longevity but at the current price is inexpensive enough to replace yearly if needed without breaking a budget.

This product was priced less than other comparable products. Thought I'd give it a try. After replacing my 2 year old cartridges, my pool water cleared up overnight. And made in USA 🇺🇸

When it came time to replace my pool filters, the local pool company told me they would be about $500. I started looking for a more cost friendly option and found these. These filters exceeded my expectations and about 70% cheaper. They lasted the same amount of time as the original filters. Shipping was really fast too!!

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.

I've seen a lot of reviews of the blue ends of the filters torn, broken and even filters crushed. I almost didn't buy them based on these reviews. After installing mine this morning I have a pretty good idea of why some people have had problems. The blue part on these filters is a hard plastic instead of the rubber that was on my original filters. The rubber had turned to mush and was falling apart, thus the reason that I needed new ones. The opening in the filters was exactly the diameter that I needed. I placed each filter in the correct position and then spun them a little back and forth until they were settled all the way down on the bottom. When I placed the top piece I tapped lightly with my fist to get it to touch the top of the blue ring. I believe you could destroy these filters if you don't ensure that both the bottom and top are seated before you put the housing back together.I ran the pump for a couple of hours and the water is crystal blue, very happy with this purchase.If anything changes I'll come back and update this review.
