Ordered these a few years back and finally figured I better replace them. Husband always keeps the old ones clean and for them to last a few years makes them a bargain to buy. They filter nicely and are easy to clean with muriatic acid after changing spa water every 8 to 10 weeks. We have a Hot Springs spa that 27 years old and these filter are a perfect fit, plus they come in 3's which makes it easy to buy, because they come in a set of 3 as oppose to two or four.

Use in hot tub work s fine

These fit perfectly in our hot tub….we have a Hot Springs Sovereign (old) and we want to keep it in as good of shape as possible. Changing these filters really helped!

These spa filters are just basic filters, but they fitted and filter/cleaned my hot tub water like they should. The filter media is little thinner, you might need to clean more. But I saved about $60.00 then buying them in town.

Hot tub filters work fantastic!

I have found for my tub it’s much easier to toss the filters then clean them.. these are good enough use the toss and replace theory. I toss every 8-10 months depending on use when I do I water change

They look good got here very fast I haven't installed them yet I would definitely get them again they got here very fast

These are perfect for our hot tub. They are easy to clean so you can use them several times. The price is good as well, cheaper than going to a spa store and buying them, by about $25 in my area.
