I've taken this little guy into the car when I've noticed the air quality outside is bad (or worse than most days currently). It's comforting to know that I can breathe clearer air while taking care of errands. I love the size, made a bag for it to fit into, and keep it in the vehicle when the days aren't too hot--not sure if being exposed to heat matters or not. It does have a limited usage, so I am particular about when I use it in the car and I turn it off when I run into places. Because our large Tiad Air Pro is on the opposite side of the house from our bedroom, I also used it one day when I felt like I was coming down with something. Either I beat it naturally or this portable air purifier helped. Either way, it's worth it and I really like the size as it fits in the vehicle's cup holder perfectly without toppling over.
