Type S1 Spa Filter Cartridge Set for Inflatable Hot Tubs

I purchased the PureSpa Filter Replacement Cartridges (6 filters) and I am so impressed with the quality. These filters fit perfectly and do an excellent job of keeping the water clean and clear in my hot tub. They trap dirt, debris, and oils effectively, which makes a noticeable difference in water quality after every use. The 6-pack is a great value, as it provides enough replacements to last a long time. They’re easy to install. I also appreciate how durable they are, as they hold up well over time, even with regular use. If you’re looking for reliable and high-quality filters for your hot tub these are a great choice. They keep the water sparkling clean-Highly recommend!

I bought this Intex filter hoping it would be the same standard filter as the one I use in my inflatable saluspa, but it is slightly taller, and the inner ring is smaller (tighter) by a little bit, and the outer ring is larger. The smaller inner ring makes the filter sit a little higher than the saluspa filter does. This isn't the product's fault because it's advertised for intex spas. All that being said, I was able to scrunch it in and the filter still worked. See the photos to see what I mean about size differences.

Works as intended. Good fit.

I’ve been using the Intex S1 Filters for my inflatable spa, and they work great. They fit perfectly and keep the water crystal clear. I also appreciate how long they last before needing a replacement. They are also easy to clean and a good value. Highly recommend!

It works well and a good value, but I change it every 2 weeks…. I don’t re wash and re use.

Works good in our spa.

These filters are a must-have if you own an Intex spa. They keep the water clean and are easy to swap out. They do need replacing fairly often, but that’s just part of spa upkeep. Great to buy in bulk.

Works perfect for my blow up hot tub
