My husband also has asthma and is a great naturalist and therefore he tends to have things like caterpillars in his pocket! and other not so nice things to do with the country.
Anyway basically he managed to inhale ( and cough out) a fluffy black caterpillar that had crawled into his ventolin inhaler!
Thought i would try yourselves to see if you know of any inhalers or devices that will prevent dirt and bits and caterpillars crawling down the sides of the inhaler between the plastic and the metal cannister.
Sorry i know it sounds yugh!
Thanks for listening.
