Quality products, great prices

The filters and chemicals have all been good quality. We love the spa scented salts. It's a great luxury to live in the mountains and have your spa products delivered to your door. We recommend spa depot to everyone we know

I buy these all the time.

I have ordered these filters from Spadepot many times. They're always in stock and reasonably prices.

Spa filter fit was OK.

Looks to be well constructed

Product and response is excellent

Hot tub filters, they last three to four months of use, wish they could last a bit longer but am satisfied with them. I've been ordering from this company for almost 5 years and am very pleased with the service and response (when I had a question) with the tec guy.

Replaced LA Spa bag filter with paper filter - worked great

This paper filter replaced the LA Spa bag filter perfectly. Easily screws in. Filters much better than bag filter to yield perfectly clear water. Paper filter can be cleaned with a spray nozzle several times before needing to be replaced with a new one. In my spa, used once a day, every day, the filter lasts 6 months with 3 cleanings, and finally replacement.

The spa filters are excellent and a great price!

Quality filters!

A perfect fit & a good solution.

These replacement cartridge filters were a perfect fot for my LA Spas hot tub and it's back to its sparkling clear turbulence.

The right filters for my spa

I received my order faster than expected, and the right products. The filters for my spa fit perfectly and they are reasonable priced. A good company to deal with.
