Highly recommend - have used for years

We've been using this filter for our hot tub for many years and always order from SpaDepot. Prompt shipment and great customer service. We once received the wrong filter and they immediately sent a replacement.

This is the 2nd time I have purchased this filter.

Quality filter. Great response time on delivery.

A tight fit

This is the second time I have bought this particular filter from SpaDepot and am mostly happy with the filters. This time though, I had to work hard to get the filter to fit. The inside diameter was perhaps one to two millimeters smaller and I could not just drop it in. The filter works just fine and I would have given it a 5-star rating except for the tight fit. Yes, I would buy this filter again.
