Swim & Fun Filterballs 700 g — pool filter media, lightweight polymer balls for sand filters

Swim & Fun Filterballs 700 g are lightweight polymer balls designed as an alternative to traditional sand in sand-type pool filters. Supplied as 700 g of fine filter media, these filterballs reduce the overall weight of the filter bed while maintaining effective particle capture and improving water flow through the filter system. They are intended for domestic pools and small commercial installations where easy handling, lower backpressure and reliable filtration are required.

Advantages

Filterballs provide efficient mechanical filtration with a significantly lower mass than sand, which simplifies installation and reduces strain on filter housings and pump systems. Their rounded polymer shape allows improved hydraulic flow and reduces channeling inside the filter, while fine pore spaces trap dirt, algae and other suspended particles. The media is quick to rinse and easier to replace compared with sand, and it contributes to lower energy consumption due to reduced resistance to water flow.

Suitable for

• Domestic sand-type pool filters (single- and multiport valve systems)
• Small commercial pool filters with similar sand media requirements
• Retrofit projects replacing sand with lighter filter media
• Situations where easier maintenance and reduced filter weight are desired

Key specifications

• Net weight of supplied media: 700 g
• Material: lightweight polymer filter balls
• Form: fine, rounded filter beads suitable for sand filter housings
• Function: mechanical particle filtration to capture dirt, debris and suspended solids
• Compatibility: designed for use in standard sand-type pool filters

How to use

Before adding the filterballs, switch off the pump and follow the filter manufacturer’s instructions for accessing the filter tank. Remove existing sand or media according to the filter service manual, then rinse the filter tank and laterals. Add the supplied 700 g of filterballs evenly into the filter housing, ensuring the laterals and distribution system remain unobstructed. Reassemble the filter, prime the pump and backwash according to the filter manufacturer’s recommended procedure to seat the media and remove any fines. Monitor pressure and water clarity after installation and adjust backwash intervals as needed.

Usage recommendations

Use Swim & Fun Filterballs as a direct replacement for an appropriate volume of sand in residential and small commercial sand filters, following the filter manufacturer's guidance on media depth and backwash settings. Rinse the media before first use and perform regular backwashing to maintain filtration performance. If in doubt about compatibility with a specific filter model, consult the filter manufacturer or a pool professional.
