Wildfires and Purifiers: How to Promote Clean Air at Home

Air purifiers can help with poor indoor air quality due to wildfires.

Wildfires and wildfire smoke have become the norm in recent years, causing panic and poor indoor air quality alike. And, unfortunately, it doesn’t seem to be slowing down.

According to research published in Environmental Health, “Smoke from landscape fires can affect communities in both rural and urban areas, sometimes hundreds of kilometers from the source. Additionally, exposures will become more prevalent as the global climate changes and wildfires become more frequent and intense.”

According to the EPA via the New York Times, children, older people, pregnant women and people with asthma or cardiovascular disease may be more susceptible to health hazards of wildfire smoke.

That said, with fire safety, of course, being the number one topic for those affected immediately by wildfires, how can smoke safety be promoted to those on the outskirts who are being subject to inhaling wildfire smoke?

Tim Heffernan, a science writer and editor at Wirecutter, suggests people in smoke-prone, wildfire-affected regions run a HEPA-certified air purifier “on high for an hour, then turning it down to medium or low, which should keep the amount of smoke in your home to a minimum.”

HEPA stands for High Efficiency Particulate Arrestance, which is essentially a rating system for air filters with HEPA. These filters are made to filter air at an exceptionally high scale and generally help remove 99.97% of the invisible intruders in your home, including wildfire smoke, down to 0.3 microns.

In wildfire situations, it would likely be most beneficial to have a whole home air purifier vs. a room air purifier installed to quell the effects of wildfire smoke throughout your home. In fact, it would likely be beneficial to use both air purifiers, using the room air purifier in whichever room you’re in to add a supplemental burst of fresh air.

Other ways to steer clear of the risks that wildfire smoke possesses include keeping the fresh air intake in your ventilation system closed to prevent additional smoke from getting inside and staying indoor as often as possible. You should also keep an eye on air quality reports and ensure that your smoke detectors have fresh batteries.

If necessary, depending on the path of the wildfire in question, listen to authorities and consider evacuation to protect yourself and your family if you feel you are in harm.
