I won't fly without it
I fly frequently for business. During the cold and flu season, there are always five or ten people on every flight who are coughing and sneezing. Thanks to the wretched recirculated air on planes, I used come down with a cold about five days after every flight. Since buying this little device, I have repeatedly flown cross-country at the height of flu outbreaks, and come home without so much as a sniffle. I have bought one for every member of my household. It seems to be very effective in preventing the transmission of viruses through casual contact. If I were a teacher, nurse, or daycare provider, I'd wear it to work every day!
Good and not good
I bought one to fight against my mold allergies anywhere anytime. It really does work, but the instructions indicate that it should be worn right under your chin with the provide lanyard. I have found the amount ozone production to be high and uncomfortable. If worn under my chin, my eyes would start watering and itching because of the highly oxidizing ozone gas. Nowadays, I wear it with a cellphone hoister. It works great that way. I can still smell some ozone, but it is not as bad as having it blow in your face. The AS150MM adds 48 ppb of ozone to ambient ozone. The maximum safe level (continuous) exposure for humans is 50 ppb. AS150MM only gives 2 ppb of margin to work with. Creating distance between the unit and my nose increases that margin. I mostly use my unit indoors because ozone levels are lower indoors than outdoors. During high ozone days, I neglect using it. Chronic asthma patients should probably stay away from getting this. It may trigger a bad asthma attack.
A miracle device!
I purchased this unit for my commute to work using public transportation.
I have an allergy that can be aggravated by a simple cold; so I want to protect myself as much as possible when away from home and car where I have several air cleaners and ionizers. Having good air quality in public places is truly priceless.
The minute I turned the unit on, it was like experiencing a shot of cold energetic fresh air! The operative word is "energetic"; I had never experienced this kind of "vitality" from air. The novelty of this makes it as much a "fun" device.
The specs are excellent, and it's a good all around unit to have, especially when going into crowed places and public restrooms.
Forget about getting an Ipod, get this thing instead; it will change your life!
On a more serious note, although no one can promise complete protection against flu viruses, this could be one of the better preventative measures. The manufacture even states...
