As wildfires burn in Los Angeles, smoke, chemicals, and particles are spreading through the air. This has led to a big jump in people searching for air purifiers, with web searches for “air purifier for wildfire smoke” increasing by 5,000%, according to Google Trends.
Here’s what air quality experts recommend:
Affordable Options Work
You don’t need an expensive air purifier. Prices range from $50 to $1,200, but even a simple fan and filter can help. Homemade air purifiers using a box fan and HVAC filter work well, though they can be damaged by kids or pets. If possible, invest in a sturdier air purifier.
HEPA and Carbon Filters
Experts recommend purifiers with HEPA filters and carbon filters. HEPA filters remove 99.97% of particles like ash, but they don’t clean chemicals. Carbon filters can remove harmful chemicals caused by burned materials like plastic and paint.
Choose the Right Purifier
When buying, check:
- The size of the space it can clean.
- The cost of replacement filters.
Create a Clean-Air Space
Focus on cleaning the air in one or two rooms, like your bedroom or office, instead of your whole house. Keep doors and windows closed and place a filter near entryways.
Maintain Your Filters
Replace filters when they look dirty or dark. Some devices have a light to show when it’s time to change. During wildfires, filters wear out faster, so check them often.
Know Your Risk
People most at risk include children, the elderly, pregnant women, and those with asthma or lung conditions. Use tools like AirNow.gov or PurpleAir to monitor air quality near you.
