Front-Access Skim Filter (Standard on all Sunbelt Spas) - During normal spa use, or whenever your spa is uncovered, little bits of junk get into the water. Your spa’s skim filter automatically removes them and keeps your water clean and clear. The only maintenance required is periodic inspection and replacement of the filter cartridge. The filter’s front-access design makes this a quick and easy operation; all you need is a calendar.

Spas in the Storm, Supreme, Ultimate and Wave Series use a 100 sq. ft. filter. Spas in the Alpha, Patio and Premium Series use a 50 sq. ft. filter. Spas in the Prestige Patio Series use a 20 sq. ft. filter
