Beachcomber’s Microfilter is a critical component to keep hot tub water clean and clear. Hidden out of the way in a dedicated and isolated reservoir, Microfilter works silently to remove and filter out impurities from the water, and protects the pumping equipment, 24/7. With just a little maintenance through regular rinsing and soaking in Filter Pure or Filter Cure, a Microfilter can last for years. The fabric pleating system is designed to easily filter out impurities to help keep water sparking and clear. Caring for the Microfilter will prevent lower water flow and excess tension on hot tub equipment. It is recommended that the hot tub owner have 2 Microfilters, one to be cleaned, and one ready to use.
