AQUA CRESTWF51 Replacement for Aquasana® Under Sink Water Filter AQ-5300+R, Aquasana® Filter Replacement, 800 Gallons, Reduce 99% of Chlorine, Taste and Odor, 3 Count

Tried this option instead of the name brand and it's been great. No issues, easy to install, and water tastes great.

Correct fit and it is working as expected

great value and easy install. Water immediately tasted and looked pure. Great water flow and faucet looks very nice too.

Excellent quality

Not compatible with Aquasana 5300+R. Prefilter does not securely fit. Garbage product.

These Aqua Crest replacement filters for the Aquasana undersink filtration system work fine. They're a somewhat more affordable version of the OEM filter, at more than twenty bucks less than the original. They installed easily and fit right and, as near as I can tell, work identically to the Aquasana replacement product. It's always nice to save some money.I'd remind people of the need to soak the filters before use. I didn't, once, and it took quite a bit of water flow to get them to lose that initial taste that filters always seem to have, whether it's a Brita or an undersink variety. Once they were soaked, though, they were ready to use much more quickly.Overall, these Aqua Crest filters are well made, came packaged well, and work just fine. The water tastes good, especially compared to the straight-from-the-faucet variety; the water flow is good; and they show no problem areas like leakage, etc. Essentially, they work just the same as the OEM version, so there you go. They may still not be completely inexpensive, but are far more affordable than the original brand and work just as well. Good product.
