I drive for a Limo company and I have to deal with a lot of unpleasant smells especially cigarette smoke. My wife got this for me as a birthday gift and it's probably the best gift a driver could ask for. I say this thing is better than Frebreze because it doesn't cover up smells it actually cleans it out the air. It's easy to use since all you do it plug it into the cigarette lighter and it automatically turns on to clean the air and turns off when done. This has made sitting and waiting in the vehicles much easier. I definitely recommend this thing

I would recommend to product to anyone who has issues with allergies. My kids are very sensitive to dust and it seems that my Tahoe must have plenty of it because they sneezed quite regularly when in it. I bought this expensive unit at the recommendation of a friend and I'm glad I did. This thing has been a life saver because since having it they have almost never sneezed. So far its worth every penny so I can't complain. I've had it about a month and haven't had to buy a new filter yet. It's not too big it's about the size of a Sega Genesis.
