PACETAP 1 1/2" SAE Thread Screw in Spa Filter Replacement Compatible with Pleatco PWW50P3(NOT PWW50P4), for Unicel 6CH-940, for Filbur FC-0359, for Waterways 817-0050, Spa Hot Tub Filter for Viking

My hot tub. Great filters and ease of installation.

Filters great definitely a great buy!

Made well and fit perfectly

I liked how easy it was to select, purchase, and install the filters. My Swim Spa has not been this clean since the unit was new.

These were a great replacement for my Unicell spa filters. The only difference was the side that has the screw in neck. It was lightly shorter than the other filters. It did not make a difference on my spa but it might for others. I would say it (the neck) was a little over 1/4 inch shorter...Just FYI

It was WAY easier to order from you. I went through Tuff Spa and got the wrong filter and they have a no return policy. Plus, your pricing is way cheaper too.

Wanted a second set of filters to change out during winter, 1 set in 1 set out. While they look great after using once, when removing milky white residue everywhere. My thoughts cellulose pleats breaking down. Rinsed to clean, milky water never stopped, so I decided to deep clean they looked great. During that time I put back in original set and water cleared. When swapping again, I used this set , removed 2 weeks later because of residue noted on pool water surface, no one swam during those 2 weeks, . Same thing happened milky residue when removing. All I can say is you get what you pay for. This issue does not happen with higher grade filters. Never have I seen this, and I have used cartridge filters before.

Good quality fast service and on time delivery
