I've been using the Volcano happily for many years and never considered anything else until recently. Direct draw inhalation seems to be generally at least as favored if not more than bag inhalation these days. I have read about some pros and cons and I will get a Direct Draw model in addition to my Volcano once I made up my mind which model is best for me. I always have slight allergic reactions to the vapor that is why I'll try and find a direct draw model now with water filtration that delivers the ultimate smooth and clean vapor. Hoping that this may alleviate my asthma and allergies even more if the Vapor is clean of particles and humidified. I thought the bag vapor from the Cano always fulfilled these criteria but maybe even cleaner vapor can be had So which method of inhalation do you guys prefer? Also do the advantages of water filtration (cooler and humid vapor with no particles) generally make up for the shortcoming of active ingredients being filtered out?
