Hello. If the appartment is like 3 bedrooms. How we can cover it with one machine? I now, that if the machine is powerful, we have a problem, that it bleaches floor or carpet (more than 15g per hour).
Well the answer is simple fans and the whole house HVAC system should be used to move the air.
As to Knowing that the 15g machine will bleach the floor that is a fallacy.
We have used millions of milligrams per hour, to kill bedbugs and we and our customers routinely use 50-200 grams per hour with no bleaching.
