You will get the fresh air after it working for a while
My pooch likes to ride in my car, like many dog owners - but as you know, he is a stinky pup and I have to deal with that stench in my car once he`s been in
It is very quiet,it's a lower noise level even the 1st fan speed
This purifier can be working once you start your car and just uses your cars cigarette lighter, it will leaving it fresh and clean smelling after a while
Used this in a vehicle, and after a couple days, I could notice a definite improvement
I highly recommend this product!
