Hot tubs and spas are great fun and relaxation for all seasons, but they also need to be properly cleaned and maintained to keep them safe and sanitary all season. Filters keep the hot tub spa water clean and help maintain balanced water chemistry. Made of material that pleats, your filter will catch debris and the smallest of particles and remove them. All cartridge filters should be cleaned at least every 1-2 months and replaced every 4-6 months (more often with high usage).
