I'll bite, so what does HA stand for?
it stands for the "HerbalAire" They now offer several models. I own a HA 2.2 and love it, there is no valve system for the bags but I've never had a problem just covering the mouthpiece with finger since I suck down a bag in just a few minutes and don't attempt to set 'em down and/or wander about. My nephew has my older HA and found some small corks that seal the MP since he likes to blow 2 bags at a time then shut his unit off, then again he finishes both bags in 10-15 minutes.
