Tier1Pool & Spa Filter Cartridge | Replacement for Pleatco PWW50L-M Waterway 817-4050, Teleweir 50, Unicel 4CH-949, Filbur FC-0172 and More | 50 sq ft Pleated Fabric Filter Media

Decent and way cheaper replacement for the CAL Spa OEM PWW50L-M. Only did not give it 5 stars since it does not have the additional support band around the middle of the filter.

1-1/2” female threads worked for my 2019 Cal Spa. Product seems to be good quality and has held up to the first couple washings.

This filter fits and works perfectly at a significant savings over the original filters that came with our hot tub. Prompt delivery was a plus. I've used three of these now, and won't hesitate to order again when the need arises.

Very good quality. Like the blue much better than a white filter!

Slightly flimsy, but overall decent product

Works great

Works well

A great price for a hot tub filter. Good quality. Highly recommend.
