MERV 13 — Wildfire Smoke & Asthma

The residential ceiling for pleated filter capture. MERV 13 catches everything MERV 11 catches, plus wildfire smoke (PM2.5), bacteria-carrier particles, and most virus-sized droplet residues — particles down to 0.3 microns.

Designed for wildfire-prone regions, asthma households, and anyone who wants maximum residential capture without moving to a HEPA-grade air handler. Higher static pressure than MERV 8 — verify your HVAC system tolerates it during the first 2 weeks.

Smoke event playbook: swap to MERV 13 at first AQI alert, run HVAC fan on continuous (not auto), close fresh-air intake, replace filter immediately after the event ends.
