Wildfire Smoke Protection

Wildfire smoke turns air quality from background to emergency: PM2.5 at concentrations urban pollution rarely touches, travelling hundreds of miles, seeping indoors — and now a seasonal fact across regions that never planned for it.

The protection protocol, before the orange sky arrives.

Why Smoke Demands Respect

The particle profile: wildfire PM2.5 is fine combustion aerosol — deep-lung penetrating, systemically absorbed, with health-effect research (cardiac and respiratory event spikes during smoke episodes) that has hardened public-health language year on year. Symptoms run from irritation to serious exacerbations; children, pregnancy, cardiac-and-respiratory conditions and outdoor workers head the sensitivity list. Smoke days are not haze — they are exposure events.

The Indoor Clean-Room Protocol

The home response: windows-and-doors sealed, HVAC to recirculate (fresh-air intakes closed), purifiers running continuously in occupied rooms (smoke is HEPA's exam — the filter guide's sizing pays off now), DIY box-fan filter rigs as proven budget surge capacity, cooking-and-candle emissions minimised (indoor sources stack on infiltration), and one room — usually the bedroom — maintained as the cleanest refuge. Monitors turn the protocol from faith to feedback.

Masks That Work

The respirator facts: N95/FFP2-class respirators, FITTED, meaningfully reduce smoke-particle dose — the seal is the spec (beards and gaps defeat it); surgical and cloth masks do little against PM2.5; valved respirators protect the wearer fine for smoke purposes. Use case: necessary outdoor exposure during smoke events — not a licence for outdoor training, which stays cancelled at smoke AQIs.

The Smoke-Season Kit

The before-season checklist: purifier capacity audited (one per occupied bedroom as the goal), spare HEPA filters stocked (sell-outs are a smoke-season tradition), respirators fitted per adult, AQI alerts configured with map views, HVAC filter upgraded (MERV-13 where systems allow), and the vulnerable-household plan written (medication supplies, clean-room assignments, evacuation-trigger clarity).

Smoke verdict: the one air-quality scenario where preparation beats improvisation by the widest margin — kit assembled in green weeks serves the purple days.
