Excellent service, fast delivery, perfect products, competitive prices. Highly recommended.
Clarathon filters have been my choice since I purchased my spa nine years ago. I highly recommend them for quality of construction, cost, performance, and ease of cleaning.
Disappointed: I measured my old filter, pick one of the same dimensions and upgraded to antimicrobial type, received it in a timely fashion but when I put it into the hot tub it floated in the filter chamber preventing the cap from being put on. Soaking it overnight did not weight it enough to sit in the filter chamber: it still rose to the top and would have floated away if the chamber walls weren't as high as they are.
Quality products and delivered quickly.
just sent a picture of the broken vent and was emailed a response with the item # I'd need to order.....I ordered them and voila! everything's back to work and I'm relaxing in my hottub once again!
