Three setups that work, simplest first:
1. **Open window + fan blowing fumes out**: fine for occasional small jobs. What I did for the first year.
2. **Cardboard / plywood hood + flexible ducting + bathroom-fan-grade extractor**: ~€40 of parts, exhausts to outdoors. Good for daily use.
3. **Proper fume extractor with HEPA + activated carbon**: €200+. For people cutting hours per day or working in a room next to where they sleep.
Don't skip ventilation. EPS fumes are mostly styrene, which the WHO classifies as "possibly carcinogenic." Not acute danger but cumulative.
