Weltico pre-filter bag Weltibag P3 500 µ

Weltico pre-filter bag Weltibag P3 500 µ

The Weltico pre-filter bag Weltibag P3 500 µ is a reusable pre-filter for skimmer baskets that captures coarse debris before it reaches the main pool filter. With a filtration fineness of 500 microns, it retains hair, insects, small leaves and other visible particles, helping to keep the sand or cartridge filter cleaner and maintain a stable, efficient water flow.

500 micron pre-filtration for everyday pool use

Thanks to its 500 micron mesh, the Weltico pre-filter bag Weltibag P3 500 µ stops the majority of larger contaminants circulating on the water surface while still allowing sufficient flow to the filtration system. By intercepting debris directly in the skimmer, it reduces the load on the main filter and can extend the time between backwashing or cartridge cleaning, especially in pools exposed to trees or intensive use.

Reusable and easy to clean

The Weltico pre-filter bag Weltibag P3 500 µ is manufactured from a durable fabric designed for repeated use. Instead of disposing of single use skimmer socks, you simply remove the bag, empty the collected debris and rinse it under running water. After a quick cleaning, the bag can be reinstalled in the basket and used again.

• Reusable pre-filter bag to reduce consumables and waste.
• Easy cleaning by emptying and rinsing with a hose or tap.
• Helps keep the skimmer basket and main filter cleaner for longer.

Designed for compatible Weltico skimmer baskets

This Weltibag P3 500 µ model is shaped to fit compatible Weltico skimmer baskets of the corresponding size. The flexible material adapts to the internal contour of the basket and provides a large effective filtration surface so water can pass through freely as long as the bag is emptied regularly.

• Installed directly inside the skimmer basket in a few seconds.
• Collects surface debris before it reaches the filtration media.
• Supports cleaner water and reduces dirt accumulation in the filter tank.

Support for clearer water and easier maintenance

By trapping larger contaminants at the skimmer, the Weltico pre-filter bag Weltibag P3 500 µ contributes to clearer water and more efficient chemical treatment. Less organic matter reaches the filter bed and circulation circuit, which can help reduce odours, staining and cloudy water caused by accumulated debris. At the same time, it simplifies weekly maintenance because most visible dirt is removed in one step when you empty the skimmer basket.
