Weltico pre-filter bag Weltibag P2 500 µ

Weltico pre-filter bag Weltibag P2 500 µ

The Weltico pre-filter bag Weltibag P2 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 larger particles, helping to keep the sand or cartridge filter cleaner and maintain a stable, efficient water flow.

500 micron pre-filtration for everyday use

The 500 micron mesh of the Weltico pre-filter bag Weltibag P2 500 µ is ideal for daily pool use. It stops visible dirt and organic matter circulating on the surface while allowing sufficient flow to the filtration system. By intercepting debris in the skimmer basket, it reduces the load on the main filter and can extend the intervals between backwashing or cartridge cleaning.

This level of pre-filtration is well suited to private pools that regularly collect leaves, insects and cosmetic residues, providing a simple way to support clearer water and more consistent circulation.

Reusable, easy to empty and rinse

The Weltico pre-filter bag Weltibag P2 500 µ is made from durable fabric designed for repeated use. Instead of throwing away single use skimmer socks, you simply remove the bag, empty the captured debris and rinse it under running water. Once cleaned, the bag can be reinstalled in the skimmer basket and used again.

• Reusable construction to reduce consumables and waste.
• Quick cleaning with a simple hose or tap rinse.
• Helps keep the skimmer basket and main filter cleaner for longer.

Designed for compatible Weltico skimmer baskets

The Weltico pre-filter bag Weltibag P2 500 µ is shaped to fit compatible Weltico skimmer baskets of the corresponding size. The flexible material adapts to the internal contour of the basket while leaving enough open area for water to pass through, provided the bag is emptied regularly.

• To be placed directly inside the skimmer basket.
• Collects surface debris before it reaches the filtration system.
• Supports clear water and reduces dirt accumulation in the filter tank.

Using a dedicated Weltibag insert in the skimmer is a simple upgrade that can make routine pool care more convenient, especially in pools exposed to trees, plants or frequent use.

Support for cleaner water and easier maintenance

By removing larger contaminants at the skimmer level, the Weltico pre-filter bag Weltibag P2 500 µ helps improve overall water quality and makes chemical treatment more efficient. Less organic material reaches the main filter and circulating system, which can help reduce odours, staining and cloudy water caused by accumulated debris.

• Reduces the amount of dirt entering the filter media.
• Can lengthen intervals between filter backwashes or cartridge cleaning.
• Provides a first barrier against leaves, insects and hair in the skimmer.

Combined with balanced water and correct filtration times, this pre-filter bag is a practical accessory to keep the pool cleaner and to simplify weekly maintenance routines.
