No chemicals -- dust is a mechanical problem for the lungs and bacteria 
biological problem that harbors on dust.  For that matter, house dust is 
likely to NOT be beneficial ... what I'm wondering just what is the Threshold 
Limit Values (TLV) and the Time Weighted Average (TWA) exposure for harm?  
All foreign bodies in the body do harm ... just a matter of how much harm and 
to how many people.  Suspect the data is hard to come by.

Agreed.
