Review Content Great Product. I would buy again. I purchased a new car and the "off-gases" are really harmful. This product removed the smell and left the car fresh. Enjoying It I really like this works well and makes the smell fresh. Nice little gadget Easy to put together and easy to use. Nice and quiet. I bought it for my car, but unfortunately the cord to cigarette lighter was so short that I had to stretch it very hard to connect to the unit. It looked very awkward. I ended up using it for my bedroom, which is fine. Also, I didnt know until I read the instruction that the AHPCO cell in the unit needs to be replaced every year.
