I've been using Ventoline (the GSK brand name they use for Albuterol or Salbutamol depending on your location), to control my asthma for years. I used to use the variant with propellant but I switched of it to the one without. The main reason I switched was environmental concerns (https://www.bbc.com/news/health-50215011 https://www.bbc.com/news/health-50215011). But after switching I find that for me, inhalers without propellant works just as well or better than the ones without. Since the propellant seems to be the problem in this case. It could be worth checking if the generics or even the GSK non propellant ones, are cheaper than the other one in the USA?
