Which ozone unit do you run? I have a Sonozaire 330A running in the back bedroom and bath right now. The 630A I use for the whole house. Also have a bunch of smaller units I don't use anymore.

Wonder if the ozone can be applied before washing, as with dirty clothes hanging in an enclosed space, then put into the washer for the mechanical removal. I don't have residue problems, but am going to do a hanging experiment next time I wash clothes.
