Weltico pre-filter bag Weltibag P5 500 µ

Weltico pre-filter bag Weltibag P5 500 µ

The Weltico pre-filter bag Weltibag P5 500 µ is a reusable skimmer pre-filter designed to capture coarse debris before it reaches the main pool filter. With a 500 micron mesh, it retains hair, insects, small leaves and other visible particles in the skimmer basket, helping to keep the sand or cartridge filter cleaner and maintain a stable water flow.

500 micron pre-filtration for daily use

Thanks to its 500 micron fabric, the Weltico pre-filter bag Weltibag P5 500 µ stops the bulk of surface debris while still allowing sufficient flow towards the filtration system. By intercepting contaminants directly in the skimmer, it reduces the load on the main filter and can extend the intervals 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 P5 500 µ is made from durable, washable material so it can be reused many times. After use, the bag is simply removed from the skimmer basket, emptied and rinsed under a tap or with a garden hose. Once clean, it can be reinstalled immediately, making it a cost effective alternative to disposable skimmer socks.

• Reusable construction reduces waste and running costs.
• Fast cleaning by emptying and rinsing the fabric.
• Helps keep the skimmer basket and filter media cleaner for longer.

Sized for compatible Weltico skimmer baskets

This Weltibag P5 500 µ model is shaped to fit compatible Weltico skimmer baskets of the corresponding size. The flexible bag adapts to the internal contour of the basket while providing a large effective filtration surface, so water can pass through freely as long as the bag is emptied regularly.

• Placed directly inside the skimmer basket in a few seconds.
• Collects surface debris before it reaches the filter tank.
• Supports efficient circulation when maintained correctly.

Support for clearer water and easier maintenance

By trapping larger contaminants at the skimmer level, the Weltico pre-filter bag Weltibag P5 500 µ contributes to clearer water and more efficient chemical treatment. Less organic matter reaches the sand bed or cartridge, which can help reduce odours, staining and cloudy water caused by accumulated debris. At the same time, weekly maintenance becomes easier because most visible dirt is removed in one step when you empty the skimmer basket.
