Do You Know What Filter You Have in Your Swimming Pool?
Here’s how to tell just by looking at it! Your pool filter is one of the most important components for keeping your water clean and safe, but many homeowners don’t know which type they have. Knowing makes a big difference when it comes to maintenance and water quality. Here’s a quick guide to identify your filter just by its shape and valves: DE Filter (Diatomaceous Earth) Common in residential pools for its high filtration efficiency Tall, vertical tank often looks like a large capsule May have a multiport valve or a bump handle on top Requires adding DE powder after cleaning or backwashing If your filter needs powder after cleaning, it’s a DE filter. They’re great for capturing fine particles but need regular attention. Cartridge Filter Also very common in residential pools low maintenance and energy-efficient Tall, slim, vertical cylinder No multiport valve just a drain plug and pressure gauge
