Comfortable, though pricey and of limited effectiveness
I ordered these for those times when I'm expected to take off my mask for appointments; any filter is some help. They fit all right in my petite face, though larger-built people may have issues with air leaks if not shoving them deep. The scent in the high-filtration ones is okay, kind of strong but not so much that it triggers issues.<br /><br />The biggest issue I have with these is the limited lifespan for the price. They're only good for a few hours total, and then have to be disposed of, and the refills are fairly expensive as well. That said, they're helpful when I go out walking, giving me the ability to stop in a shop to purchase a drink if my water bottle runs empty.
