Buying guide: hot tub and swim spa filters
Our filters are listed by height, width, thread type, top and bottom hole width and reference code, and some product pages name the models they fit. Measure your old cartridge first, then find the product pages that match those measurements. If you cannot find a match, ask our team before you order.
Measure the old cartridge's height and width, and check its top and bottom hole widths and whether the thread is male or female. Then find the product pages that match those measurements and the reference code printed on the old filter. Where a product page lists the models it fits, check that your tub is on the list.
