It only ramps up when I use my facial toner - that is how sensitive it is

Just make sure you choose the correct model to match the square footage of the room in which it will be used

Each day, I took one Rx antihistamine, two Rx nose sprays, one Rx inhaler, one OTC decongestant, one OTC nose spray, and I was also getting weekly allergy shots
