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. We recommend replacing or cleaning your filter every 4-6 months.
