Hi, Danny,
We have one in our home because I smoke.
To be honest, I notice very little difference and I doubt this unit is really moving
a very large amount of Cubic Foot per Minute but, when you open it up to clean
it, you can really see the discoloration on the plates inside so, it is removing some
smoke and dust particles.
We used to have a humidifier for the winter months and it really did a good job of
keeping the humidity level good in the house and stopped static cling. It finally quit working
and we never replaced it.
Good luck in making a decision.
God Bless! Spirithorse
