Malaka Spa Replacement Filter FD2007 Compatible with PWW50L 4CH-949 FC-0172, Hot Tub Replacement Filter Cartridge, 2-Pack

So far so good. My water looks great!I was afraid of buying a filter online from an unknown seller, but these filters look good and they fit my hot tub perfectly. I have only had them a couple weeks, but I will update if needed.

Seems to be doing a pretty good job keeping the hot tub clean.

Was originally leary of buying compatible filters for the PWW50L in our swim spa, but these work great. Our swim spa is split into 2/3 being the swimming part and 1/3 being the hot tub. We need one of these for each section. They do a great job of getting cloudy water clear again, but they do need to be cleaned if you want to reuse them. I know there are methods for officially cleaning them including the use of other chemicals, but I haven't really gotten those to work. We either let them dry for about a week then knock/clean out the flaky dirty on the filter surfaces (not quick to do correctly) or we use a sprayer head (powerful but shy of a power washer) while they're still wet to spray the slime off. They're not perfect when we reuse them, but that gets them in good enough condition to filter the water again.

Good product at all good price Arrived quickly 👍
