    I have used All About spas for both our current home and my prior home (where we left our old hot tub) and they have always been quick to deliver, their products are OEM or very high quality alternatives. When I had a question on my old hot tub about which filter to get as their were many choices, I actually had a live person answer who was very helpful Their prices have also been consistently fair and good beating Amazon every time. I will continue to use All About Spas for my spa/filter/chemical needs.

    We're back in the tub! Thanks to All About Spas, our hot tub is up and running with sparkling clean filters. This purchase was easy, and the delivery was free and prompt. Hey! Did I mention the price was right, too? Thanks, All About Spas!

    I had ordered the same product from a seller on Amazon. Cancelled that order since seller had not been able to deliver after waiting one month. Placed order with All About Spas on a Tuesday and received the order just two days later. Will be bookmarking the website for future needs.

    I could not find a least costly company for my 5 Tri filters. I tried going out of state to save the sales tax, but even with the sales tax my filters cost less. I felt better about supporting a NM company. Received filters in just a few days.

    I order my filters about a week ago and I was surprised to how fast they showed up. The process was easy and the emails that I was provided keep me informed to what was going on with my order. All of this was a good experience and the price was way more reasonable than my local choices.
