My old lady is allergic, my eyes are dry, and one of my kids has dry skin. I've heard the particulate matter around wood stoves can be problematic for any of those conditions. There are several reviews of expensive air filters I've seen here and there. Some are rated very highly. What do you use for air filtration? I have seen one post with somebody strapping an air filter on a box fan to clean the air. Others use air ionizers. I'm open to any suggestions. Some have said that $1000 air filtration units have made their homes much more enjoyable, and I'm not totally opposed to investing in a system that will make my dry eyes less irritable. If it can be done with a little home engineering I'd rather go that way and save 99% of the cost to get 80% of the benefit. What do you use to clean your air?
