Arrived and satisfied

Exactly as advertised.

It's a pool filter, what can I say?

It's just a filter, so pretty boring stuff. The SpaDepot though, really rocks with great inventory, intelligent advice and stellar service. Thank you!

Filters for Soa

Filters arrived ahead of time and fit perfectly.


I called in an order and didn't know what filter I needed so the rep thought I needed this one but it was wrong so I measured the one I had and we figured it out and I ordered a different one and they are PERFECT! and I want to order two more in the near future. the only reason I gave 3 stars is because I was very happy with the service and product but it cost me almost $20 to return them and that made me a little sick because I don't have extra money to toss :-) But LOVE the ones I needed and got and planning on ordering very soon a second set and then I'll put 5 stars :-)

Still buying filters

My Thermospa is almost 25 yrs old. And SpaDepot still carries the correct size filters for it.
