Your Inhaler Has A Job. So Does AirWash.
Most treatments don't actually do anything to help solve the root of the issue. Inhalers are made to open your airways, usually only being put to use after the reaction has already started. Airwash stops the reaction from happening in the first place by cleaning the air you inhale.
Now you can actually protect your airways from the actual problem - exposure to harmful particles - instead of constantly over-relying on medication & inhalers to numb or lessen the effects of a reaction that could be prevented from happening in the first place.
