Ok look they do actually offer you a free gift if you STOP, take some time out and LISTEN to them about their product which you obviously didn't do in the first place or else there wouldn't be these comments. 1. you did do a survey that's how they get your info, 1 or 2 questions. Something your not going to remember do you remember everything you did or ate in the past 2 years? NO didn't think so. 2. you do get a free gift if you only give them an opinion on the bigger version of it 'bout the size of a foot stool. even if your not interested in the bigger one or buying it you still get your free gift..if your time is worth more than 400.00 well then congratuf*ckinlations Rockefeller sorry to waste your time. I bought one and i have the free gift, i put the gift in my car and i have the machine in my house, it's a 7 stage system, my husband has copd and when the rep was showing us how it worked in 20 mins my husband wasn't wheezing anymore. So shame on you selfish pricks who don't even consider your family with breathing issues.These people are trying to do their jobs, you dont see them come to your job and slap the broom out of your hand.

Yes I believe as so many know it here..it's a SCAM!!   If one was to win a prize ...the folks would certainly tell one what the prize was.  Geesh...what a scam indeed.Told them to take us OFF their list!

truly the worst company on the  planet ripping people off, just go online and find ther zephyr for 100 bucks not 3000. nuff said don't be stupid.

not quite comparable... not as many filters in this product....

unfortunately this "company" has chosen a name too similar to ours in the medical equipment field and we are constantly getting calls from confused disabled seniors who are getting the cold cars " from a survey" . If you have to bamboozle a senior and trick them into listening to your pitch.. its not a good product. Good products sell themselves. We are looking into the legal ramifications of them causing our clients confusion.  will report more later
