Spa Depot was easy and fast. They helped with finding the correct spa filters and got them shipped within 3 days.
Keeps my spa crystal clear and they last a long time.
I replace my filters every six months and these filters are perfect always great quality.
We use these filters in our hot tub and recently they had been difficult to find. The price is great and delivered in a timely fashion. They work well in our hot tub and I would definitely order again.
I was very happy to find this filter. I searched stores and online. This one from SpaDepot fit perfectly.
Nice filters, cleaning products, quick shipping and excellent price
Perfect fit and as good if not better than OEM filter.
I have ordered this filter a couple times for my spa and it's arrived quickly and works great.
Great prices and fast shipping
