Hi Mari, yes they can!
I should have included a link to the video that made me purchase this air purifier in the first place! Here is a video of the Airmege 400 clearing surrounding smoke in a matter of seconds.
My Airmega tends to go on high mode every time I cook a steak or try and season my cast iron skillet. That’s mostly from the smoke those activities put off. It basically returns my place to normal after about 10-20 minutes on high.
The Airmega will work, but I wouldn’t nessesarily recommend it unless prices isn’t an issue or the space is more than about 800 sq ft. There’s also the Coway Mighty, which is manufactured by the same company, but is about half the price.
To be fair any HEPA air filter should help with air quality due to wildfires. According to Wikipedia, to qualify as a HEPA filter it must remove (from the air that passes through) 99.97% of particles that have a size greater-than-or-equal-to 0.3µm—basically very small particles.
Hope that helps!
