FAQs on Catalina Spa Filter
How do I clean my Catalina spa filter?
Cleaning a Catalina-compatible spa filter involves gently rinsing the pleats with a garden hose to remove surface build up. For accumulation of oils and organic matter, cartridge filters may be soaked in a filter cleaning solution or detergent following manufacturer directions. Rinse thoroughly. Cartridge-style pool filters are easily replaced when worn down from normal use.
Where can I buy Catalina spa filter replacements?

How do I install a Catalina hot tub filter?
Catalina-compatible filters by SpiroPure are designed as compatible replacements, so installation is identical to OEM filter replacement. Turn off the pump and relieve system pressure, then open the housing and swap cartridges, being sure to clean out any debris from the housing.
What is a Catalina Spa Filter?
Catalina Spa Filters' compatible replacements sold at All Filters are pleated, cartridge-style filters designed to remove dirt, debris, sediment, oils, and other organic matter from spas as the water circulates through the system. They are critical components along with water chemistry for clean, hygienic water.
How often should I replace my Catalina spa filter?
With normal use, Catalina-compatible spa filters should last 12–18 months or more. SpiroPure replacement cartridges are designed to match Catalina spa filters performance, but heavy usage and poor water quality may lead to more frequent replacement. Some spa owners buy in bulk, preferring the ease of replacement to cleaning filters.
