6 Pack Blue Spa Filter Cartridges, Pool Hot Tub Filters Replacement, Filtration Inflatable Hot Tub

Wasn't able to find the screw on filters anywhere but here, so thank you for having these available! They work PERFECT for our soft-tub hot tub. :)

Seems adequate lots of debris still in water floating around one filter close to pump changed out it was gre blackish after 1 week and the other filter still white with minimal debris that rinsed out.

I ordered these hot tub filters for a standard size outdoor hot tub. While it doesn’t fit those, it perfectly fits an inflatable hot tub. It includes six filters, so one purchase will last a while. They are good quality.

These look like the filters I needed, right size, right shape, exact dimensions but it wasn't until they arrived that I realized the bottom was solid and that the center hole didn't go all the way thru. My mistake as I should have examined the tiny thumbnail photos more carefully. In one of the photos there is a small picture of the bottom of the filter. Sad. Great price but these are just not going to work for me. I wish the pictures would have been a bit more explicit.

This filter fit my Relxtime Hot Tub. I love this HOT TUB. It is great therapy for my knee as I had knee replacement surgery. It softens the pain and helps with knee excersizes, flexibility and range of motion. It is my knee therapy. This tub is my new best friend. The price was very reasonable, sturdy construction for being an inflatable hot tub, rigid inner support, easy set up with a second person, cover to protect water and hold the heat in. Easy to step in and out. The pump fittings were not adequate and a pump was not provided. My neighbor had a pump to inflate a mattress, which worked. The drain plug on the outside of hot tub comes with a fitting to attach to your garden hose to empty hot tub. Even if this tub only lasted a few years...I would be satisfied. As this is a less expensive option than getting a gym membership with a hot tub. I would highly recommend. I love this HOT TUB. 1 concern is no chlorine or salts are recommended to help with quality of water to prevent any bacteria growth. It is recommended to change out the water every 1-3 months.

It’s fits the inflatable hot tub!

It’s so convenient to buy these filters online. We love our inflatable spa from WAYFAIR!

Perfect

Seem good! Filters are not very complicated things. Oh and the stuff in the background is our hand made ceramics made in our home studio at reeseedceramics dot com.

Took longer to ship than expected. Seem to work fine compared to filters that came with the spa
