About Guardian Filtration

Based in Northwest Pennsylvania since 2003, Guardian Filtration Products began with a simple goal - manufacture high-quality pool & spa filter cartridges that don't cost an arm and a leg. We've maintained that goal for over 14 years, manufacturing and warehousing over 200 of the most popular cartridges - a number that continually grows based on the demands of the market.

Guardian Filtration Products is a brand created with the consumer in mind - manufacturing proven, quality products that are affordable for pool and spa professionals.
