Mesh vs Fabric — Which Filter Do I Need?

BWT Cosmy robotic cleaners are compatible with two outer filter types:

• Mesh filter (AS1054100) — 100 micron mesh, suited to everyday pool cleaning and general debris such as leaves, insects, hair, and larger particles. Good water flow and easy to rinse. View the BWT Cosmy Outer Filter 100 Micron (AS1054100).
• Fine fabric filter (AS1054300) — this product. Finer filtration for fine dirt, dust, sediment, and algae. Choose this when your pool has visible cloudiness or fine sediment that the mesh filter does not fully capture.

Frequently Asked Questions

What is the AS1054300 filter?

The AS1054300 is the genuine BWT fine fabric outer filter (Outer Filter Fabric 4D, ref 125683029) for compatible Cosmy robotic pool cleaners. It provides finer filtration than the standard 100 micron mesh filter, capturing fine dirt, dust, sediment, and algae spores.

What type of debris does the fabric filter collect?

The AS1054300 is designed for fine particles including fine dirt, dust, sediment, and algae spores. It is particularly well-suited to pools with visible cloudiness or a fine layer of sediment on the pool floor.

What is the difference between the BWT Cosmy mesh and fabric filters?

The mesh filter (AS1054100) is the 100 micron everyday option for general debris with strong water flow. The fabric filter (AS1054300) provides finer filtration for fine dirt and sediment. Most pool owners use the mesh filter for regular cleaning and switch to the fabric filter when finer filtration is needed.

Is the AS1054300 suitable for my BWT Cosmy robot?

The AS1054300 is compatible with BWT Cosmy 100, 150, 200, 250, and Cosmy Star. Please check your existing filter part number before ordering, or contact us to confirm.

How do I clean the fabric filter?

Remove the filter from the robot and rinse with a garden hose after each use. Allow to dry before reinserting. Avoid high-pressure washers and inspect regularly for wear. Replace when filtration performance declines.
