Pool filtration balls Bestway Polysphere — round white, 500 g, pack in color box

Bestway Polysphere pool filtration balls are lightweight, round white filtration media designed for above-ground and cartridge pool filtration systems. Supplied as a 500 g pack in a full-color retail box (package size 165×340 mm), these cotton-like balls act as an alternative to sand or disposable cartridges by collecting fine debris and reducing flow resistance. Made from recyclable, non-toxic material, the Polysphere balls are intended for repeated use and can reduce the amount of sand or cartridge material required while improving circulation and pump efficiency.

Advantages

Polysphere filtration balls provide comparable filtering performance while using a small mass of material: just 28 g of Polysphere media can replace 1 kg of sand in equivalent filtration. Their low weight and porous structure lower backpressure in sand-type filters, which can increase pump flow rate and reduce strain on the filtration system. The balls are recyclable and non-toxic, reusable for several months with routine cleaning, and come packed in a convenient mesh bag for easy handling and rinsing.

Suitable for

• Above-ground pool sand filters as a sand replacement or addition
• Cartridge filters where additional fine-particle capture is required
• Seasonal pool maintenance and interim filtration between cartridge changes
• Home pool owners seeking reduced waste and easier filter cleaning

Key specifications

• Net weight of media: 500 g per pack
• Color: white
• Form: round, cotton-like filtration balls
• Packaging: full-color retail box with included mesh bag

How to use

Place the Polysphere balls into the included mesh bag and introduce the bag into the filter housing according to the manufacturer’s instructions for your specific sand or cartridge filter. Use approximately the amount recommended by the filter manufacturer calculated by volume equivalence, noting that 28 g of Polysphere media approximates the filtering effect of 1 kg of sand. Rinse the balls by hand or with a gentle hose rinse when cleaning the filter; allow them to dry before storage if removed. Replace or refresh the media periodically based on water conditions, visible debris accumulation, and reduced flow performance.

Usage recommendations

For best results, combine Polysphere balls with routine filter maintenance: inspect and rinse the mesh bag weekly during peak use, avoid excessive chemical exposure that could shorten media life, and follow your filter system manufacturer’s guidance on media volume and placement. Store unused packs in a dry area away from direct sunlight.
