Wildfire Smoke in Los Angeles: How to Reduce Drafts and Improve Indoor Air With the Right Windows & Doors

Upgrade the seals (not just the look)

For smoke and drafts, the small details matter.

• Quality gaskets and weatherstripping help reduce infiltration

• Properly adjusted rollers and locks on sliders help the panels seat correctly

• Threshold condition is huge on patio doors—worn parts often equal airflow

Don’t forget the door from the garage

In many LA homes, the garage-to-house door is a major leakage point.

• Replace worn door sweeps and seals

• Ensure the door closes and latches consistently

Quick DIY checks

• Incense test: on a windy day, move an incense stick around edges and watch for smoke movement (carefully)

• Hand test: feel for airflow at corners and along meeting rails

Short FAQ

Do new windows “filter” smoke?

Windows don’t filter air like a purifier, but tighter assemblies can reduce unwanted airflow.

Should I run my HVAC during smoke days?

Many homeowners run the system to circulate and condition indoor air, but check your filter and settings—and consider professional guidance for your specific setup.
