Do air purifiers actually help with wildfire smoke?

Yes. True HEPA filters capture PM2.5 particles, which are the primary health hazard in wildfire smoke. Run them on high when AQI is elevated and keep doors and windows sealed.

How many air purifiers do I need?

One per bedroom and one for your main living space. A purifier rated for 300 square feet will struggle in a 1,000-square-foot open plan. Match the purifier's rated coverage to your room size.
