More wildfire smoke likely to sweep into western Washington

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 those regions into western Washington.

With the wildfire season likely to extend well into September, another change in the winds can sweep even more smoke across western Washington and toward the Pacific Ocean.

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

With the strong likelihood of suffering more wildfire smoke and poor air quality, here are some steps to take in case more smoke blankets the area where you are.

Remember the masks from the pandemic era? Those N-95 masks are the best option to help keep those small wildfire smoke particles from your throat and lungs.

If possible, shut down HVAC unit vents that serve your home or business to help ensure the smoke stays outside. Also keep windows closed.

How to filter wildfire smoke on a budget

Homemade air filters can be made. They are simple, rather affordable, and effective. All that is needed is a typical 20-inch-by-20-inch box fan, a similar-sized furnace filter rated MERV 13 or higher, cardboard, and duct tape. The fan should be aimed to blow out, and the arrows on the filter should point inward, with the duct tape wrapped up tight around the filter on the fan.

If you have central air conditioning, ensure the filters in the unit are replaced with fresh ones. Set the air on circulate and close vents that pull air from outside.

If using just a room air conditioner, it can be helpful if used with a fresh filter as well. Duct tape will help secure the airflow through the filter. This solution is not usually perfect, but is better than nothing.

Monitor air quality conditions near where you are. Visit the Washington State Dept. of Ecology air quality map for the latest readings near you.

Being exposed to wildfire smoke can lead to shortness of breath, a sense of burning in the eyes and nose, and headaches. If your body is telling you something regarding these symptoms, move inside and to an area with cleaner air. If symptoms become worse, a trip to the emergency room may be needed. The American Red Cross also offers more information about wildfire smoke safety.

In the last decade, the Pacific Northwest has suffered wildfire smoke nearly every year, and this year is no exception. To stay healthy, particularly for those with underlying medical conditions, be sure to take steps to avoid the impacts of wildfire smoke.
