Waterdrop NSF 42 Certified Water Filter, Replacement for All PUR®, PUR®PLUS Faucet Filtration Systems, Pur® RF-9999® Faucet Water Filter, 18-Month Value(6 Count)

I bought this to replace my pur in sink purifier. I was reluctant at 1st because I did not know even though it said it would fit my model but it did. It was easy to replace and works fine. Too soon to rate how long it lasts compared to a real pur.

These work better than the original that come with the filer, they fit in perfectly and work well.

They work well and are priced reasonably.

I bought these as a much cheaper alternative to the Pur brand filter cartridges. These ones fit the Pur faucet-mounted filter just fine, but the flow rate through the cartridge is much faster than through the original Pur cartridges, leading me to wonder whether it is doing as good a job of removing contaminants. I honestly don't know what there might be in my water that I'd want to filter out, and no way to test the relative efficacy of different filters. I plan to keep using these, but I'm not sure they're doing as good a job as the Pur brand.

What I ordered is what I recieved very quickly!

Works well in my kitchen faucet filter even though it’s another name brand. Very effective!

Works great

It is really good and easy to refill
