VEVOR Pool Filter Balls 1.5 lbs Blue Polyester Fiber 50 mm

Pool Filter Balls 1.5 lbs

These lightweight blue polyester fiber balls replace traditional sand in sand filter systems for swimming pools and aquariums. Each ball measures 50 mm in diameter and the package weighs 1.5 lbs. They trap fine particles such as pollen, dirt, and grass clippings to restore water clarity. The media is reusable and designed for long service life.

Best for residential pool owners wanting easier

The balls are far lighter than sand, making transport and filter changes simpler for home users. They suit above-ground pools, in-ground pools, and aquarium tanks that use a sand filter pump. Buyers who need a non-polyester media or who operate a cartridge-only filter should look at something else. Commercial facilities requiring very high flow rates may prefer alternative media.

Simple drop-in replacement with washable convenience

Pour the balls directly into the filter tank to replace sand, using the included cleaning net bag for handling. The media supports standard backwashing cycles and can be machine washed or hand washed for reuse. Ensure the pump is off and the valve is set correctly before filling to avoid air locks. Overfilling beyond the filter's rated capacity can reduce flow and filtration efficiency.
