I have ben in my house all day with the AC and de-humidifers, and a homemade air filter made from a big furnace filter and a big thick cardboard box and a fan. I think the de-humidiferers actually grab a lot of fine particulates into the condensate water on the evaporator.
The air quality inside my house has been OK all day. But I went outside to get something out of my car for a few minutes, just a short while ago ( 10:30 PM ) and the " smoke " smells like it is a about 1/4 from wood burning and about 3/4 from plastic and chemicals burning or being put into the air.
I have been at many campfires in my years, and the smoke outside is not like any wood fire that I ever smelled in my lifetime. I think some companies figured it's a great opportunity to throw a lot of burnt trash into the air and not get caught at it. It certainly smells like burning plastic. Only a hint of burning wood in all that's in that air out there right now. It is pretty bad out there right now.
