Guardian Filtration Pool and Spa Filters Perform Better Made in the USA This premium cartridge filter is made in the USA at our Greenville, Pennsylvania production facility. We use premium filter material, superior filter cores, and chlorine resistant end caps to ensure a product that filters pool and spa water more efficiently to keep you and your family safe. Our USA made filters last longer compared to competitor cartridge filters. Premium Pool and Spa Filtration Our premium filter material and expansive flow core work together to increase the efficiency of your pool or spa's pump. That means more particles, oils and debris are filtered faster and easier by your pump every minute. That means less wear and tear on your pump, which saves energy and maintenance costs, while keeping your water safe and clean at all times. Expansive Flow Cores The Guardian Core Advantage ensures maximum water flow. That allows our premium filter material to capture more dirt and debris per gallon of water pumped. Besides cleaner water in your pool or spa, this helps reduce stress on your pump which can save you money on water, maintenance costs and energy costs over the course of your pump's life. Easy to Clean Cartridges Remove your Guardian Filtration cartridge and clean it quickly and easily to give the cartridge new life and superior filtration. Because you can easily clean your Guardian filter, each filter lasts longer. This ultimately saves you money on filter costs every season. We recommend having two filters on hand for zero filtration downtime while cleaning and to extend the life of each filter.
