Buyer’s Guide: How to Choose the Best Air Purifier for Mold
- True HEPA or H13 HEPA filter – Only these capture mold spores effectively.
- Room size & coverage – Choose a purifier rated for 20–30% larger than your room.
- CADR rating – For mold, 200+ is recommended; higher CADR = faster removal.
- Carbon filter – Reduces musty odors and VOCs from mold.
- Avoid ozone-producing purifiers – They don’t remove spores and can worsen respiratory issues.
Extra Tips to Control Mold
- Use a dehumidifier (keep humidity under 50%)
- Fix leaks immediately
- Improve ventilation
- Clean visible mold with proper solutions
- Replace HVAC filters regularly
💡 Remember: Air purifiers remove mold spores from air—they do not kill mold growing on walls.
