What does HEPA mean?

Can air purifiers help with wildfire smoke?

Yes. Wildfire smoke is adversely affecting the air quality in parts of the country. Experts recommend keeping windows shut, staying indoors, running an air purifier with a HEPA filter, and avoiding tasks that can stir up fine particles, like vacuuming. One of the best air conditioners with a good HVAC filter can also supply some relief.
