HEPA air filter

The article outlines methods to maintain indoor air quality during wildfires, including using high-efficiency air filters (MERV 13 or higher), HEPA air purifiers, and DIY box fan filters. Experts from the University of Oregon and the Environmental Protection Agency recommend sealing AC units, running systems in recirculation mode, and creating 'clean rooms' with portable filters to mitigate health risks from wildfire smoke.

The article provides guidance on maintaining clean indoor air during wildfires, emphasizing the use of high-efficiency air filters (MERV 13 or higher), HEPA air purifiers, and DIY box fan filters. It highlights the health risks of wildfire smoke particles and recommends sealing AC units, recirculating indoor air, and creating 'clean rooms' for safety.

Wildfire smoke poses health risks due to tiny airborne particles, and experts recommend using high-efficiency filters in HVAC systems, portable HEPA air purifiers, or DIY box fan filters to maintain indoor air quality. The University of Oregon and the EPA endorse these methods, emphasizing MERV 13-rated filters and sealed AC units to minimize pollution exposure.
