Blazing fast delivery

Nice to get such good service in these days of supply chain issues. Also, my local dealer price gouges on spa filters so I really appreciate Spa Depot

Our second set

We bought a pair of these filters for our hot tub. This is our second such purchase - as far as we can tell the first pair have performed as well as the original filters provided with the hot tub (as we switch pairs when doing a drain/refill cycle) so we wanted a spare set on hand.
