Replacement Filter for 2013+ Bullfrog Spa – 10-2870 Antimicrobial with Longer Threaded Fitting

Most newer (2013+) Bullfrog spa models require a longer threaded fitting. This cartridge threaded fitting extends approx. 1-1/8″. (Old style fitting only extended about 3/4″, and is not long enough to keep filter in place on newer models.) Clarathon Premium Ultra Filters: the most effective, durable pool & hot tub spa filter cartridges. You cannot buy a better quality filter at any price.
