MERV tops out at 16 (\~95% at 0.3 microns), while HEPA 14 captures 99.995% at 0.3 microns under EN 1822 — which is why HEPA grades use the EN 1822 scale, not MERV. **Does the AirPro capture ultrafine PM1 and diesel particles?** Yes. Its HEPA 14 filter captures 99.9% of particles down to 0.1 microns, covering PM1 and most ultrafine traffic and combustion particles — finer than the PM2.5 most purifiers target. **How much clearance does it need?** A few inches of open space on all sides so the 360-degree intake can draw air freely — avoid corners and don't tuck it under furniture.
