Customers praised this spa filter for its perfect fit and quality, with many noting "fast shipping" and "great price." Most found it works well in Caldera hot tubs. However, some shoppers reported fit issues requiring modifications - one had to "file about an 1/8 inch off the bottom hole" to make it fit. Overall, customers appreciate the value and delivery speed.

Good supplier.

I'm a repeat customer of spadepot. I have only got filters, but it's quick and easy to find the correct one. Products arrive in a timely fashion. Negative, pop up ads in the review page.

Does not slide into place.

This does not fit a Caldera spa unless you cut or grind out the hard plastic lip at the base of the filter. A tedious and messy undertaking. I have purchased a number of this same filter over the years that slid right into place. Manufacturing error that needs to be corrected.

We always order our spa filters & filter cleaner from SpaDepot and will continue to do so. Quality products and fast shipping.

Top drawer

Really pleased with the quality. The pleating is denser and the filter itself is at least 50% heavier than factory original. Evidently the plastic walls are much thicker. And all for less money. You go Spa Depot!

Great Fit!

I use the filters in my spa. They work great and I have not had a problem with them. I also think the price is very fair. I like ordering from Spa Depot. Shipping is always very quick and good communication. Highly recommend this product and others from them.

Fantastic service!

Since I am not able to purchase filters for my hot tub in the small town I live in, I really appreciate the selection and service I receive from Spa Depot.

Finally the right filter

I ordered replacement filters for my hot tub from 2 different sites before using spa depot, both of them sent me the wrong filter not once but twice. Spa Depot not only sent me the right filter but it was a little bit cheaper than the other two sites and it only took one order. I will be using them for my spa needs in the future,

First-time purchase

The only reason I didn't give this a 5th star is the handle is a little different than the original spa filter. I can't get as good of grip to pull it back out because the handle's molded design is too straight rather than an extra indentation for better grip.. Other than that, seems a perfect match.

Excellent products at an incredible price!

We ordered two spa filters and couldn't be happier with our purchase. The price was amazing, and the ordering process couldn't be simpler.
