The smoky skies aren't just affecting what you see—they're affecting the air you breathe inside your home, too.
When wildfire smoke lingers, fine particles can make their way indoors, impacting your home's indoor air quality. Keeping windows and doors closed helps, but your HVAC system also plays an important role.

✔️ Replace your air filter regularly—especially during smoke events.
✔️ Run your fan to help circulate and filter indoor air.

When was the last time you checked your air filter?
A dirty filter can restrict airflow, reduce efficiency, and increase energy bills. Check your air filter every month and replace it every 1-3 months or as per manufacturer’s instructions.
