# Filters Module

The filters module provides multiple variant filtering approaches:

- **bcftools pre-filtering** - Fast filtering during variant extraction
- **SnpSift filtering** - Feature-rich filtering on VCF data
- **TSV filtering** - Late-stage filtering on extracted data
- **DataFrame filtering** - Final filtering using pandas query syntax
