What sizes particles does Delta Dust contain?

Ironically, a faulty air purifier being used to help filter Delta Dust has sprayed the dust all over the house. We are attempting to purchase an AC filter with a high enough MERV rating to filter it but are unsure of size or if it can be done.


Delta Dust Insecticide is a fine white powder, but we advise contacting the manufacturer Bayer directly for assistance with specific product questions at (800) 331-2867.
