Asthma relief
As someone who has asthma, Boost is a welcome addition to inhalers. Helps me to a good inhalation and get the most out the inhalers. My only complaint and the reason for giving less than 5 stars is that I’m on the smaller side and the mask on the 10 liter can is so big my I have trouble using it. If I turn it upside down and backwards I can get a good seal. Great product!!
