Find the right filter cartridge

2. Search by spa manufacturer


If there is more than one filter below, have a look at the shape of the filters to see if you recognize yours. If you spot one that looks like a likely candidate, then check the dimensions (diameter and length) listed. If your filter is within 5 mm of the dimensions you have found your filter. If we have it in stock, it will be delivered to you in two to three business days after you place your order.
Even if your manufacturer is not on the list we may still have your filter. Try searching by dimensions instead.
