Wildfires continue to burn in Eastern Washington, Eastern Oregon, and the interior of British Columbia. A few weeks ago, a change in wind flow spread smoke from these regions into Western Washington and Oregon.

With the wildfire season likely to extend well into September, another change in the winds could sweep more smoke toward the Pacific Ocean.

In addition, the west side is also dry and ready to burn. If any fires start, they will produce another source of wildfire smoke.

Here are some steps to take in case more wildfire smoke blankets the area in your area.

1) Remember the masks from the pandemic era? Those N95 masks are the best option to help keep those small wildfire smoke particles out of your throat and lungs.

2) If possible, shut down HVAC units that serve your home or business to help ensure smoke stays outside. Also, keep windows closed.

3) Homemade air filters can be dimple, relatively affordable, and effective. All that is needed is a typical 20-inch-by-20 inch box fan, a similarly sized furnace filter rated MERV 13 or higher, cardboard and duct tape. The fan should be aimed to blow outward, and the arrows on the filter should point inward with the duct tape wrapped tightly around the filter and fan.

4) If you have central air conditioning, make sure the filters are replaced with fresh ones. Set the system to circulate and close vents that pull air from outside.

5) If you use a room air conditioner, it can be helpful if used with a fresh filter as well. Duct tape can help direct airflow through the filter. This solution is not usually perfect, but it is better than nothing.

6) Monitor air quality conditions near you. Visit the Washington State Department of Ecology air quality map.

7) Exposure to wildfire smoke can lead to shortness of breath, burning eyes and noses, and headaches. If you experience these symptoms, move indoors to an area with cleaner air. If symptoms worsen, a trip to the emergency room may be needed. The American Red Cross offers more information about wildfire smoke safety.

In the last decade, the Pacific Northwest has experienced wildfire smoke nearly every year, and this year is no exception. To stay healthy, particularly if you have underlying medical conditions, be sure to take steps to avoid wildfire smoke.
