## Description

Sampson Platinum polypropylene felt filter bags deliver dependable liquid filtration with outstanding chemical resistance for the most demanding industrial processes. Polypropylene is one of the most chemically inert filter media available, making it ideal for applications involving strong acids, alkalis, and aggressive solvents that would degrade other filter materials. Constructed with welded sides and bottom seams to prevent fiber migration into your process stream.

## Why Choose Polypropylene Felt Filter Bags
- **Superior chemical resistance** — Polypropylene is inert to most acids, alkalis, and solvents at room temperature
- **No fiber migration** — Welded seam construction keeps filtration media contained (sewn also available on request)
- **High dirt-holding capacity** — Felt depth filtration captures particles throughout the media, not just on the surface
- **Cost-effective** — Excellent balance of performance and value for routine industrial filtration
- **Wide micron range** — Available from 1 to 200 microns for coarse pre-filtration to fine polishing

## Common Applications
- Chemical processing and aggressive solvent filtration
