Wildfire Ash Cleanup: Safe HVAC Filter Replacement Protocol

Safe Handling of Post-Wildfire Filters

Following a major wildfire event, your HVAC air filter will be caked in dense, gray-black ash composed of carbon soot, mineral oxides, and heavy metals. Removing a loaded filter carelessly can shake millions of respirable particles directly into your home's airstream.

1. Wear an N95 Mask and Gloves: Protect yourself from inhaling agitated ash dust.
2. Shut off HVAC Power: Never pull a filter while the blower fan is spinning.
3. Slip into a Heavy Plastic Bag Before Moving: Wrap a trash bag around the filter slot opening and slide the filter directly into the bag.
4. Wipe Down the Metal Track: Use a damp microfiber cloth to remove settled soot before inserting the fresh filter.
