Needless to say, this is a great product. Before using it, my biggest concern was car fumes! On the highway you can often smell the exhaust fumes from those big trucks and old cars! Since their exhaust emissions are particularly high, gray smoke can even be seen with the naked eye! If you walk behind them, you always smell some serious exhaust! So I had to turn off the external vent button! But it bothers me! Because it seems to me like I'm inhaling carbonic acid, which keeps throwing up! After using Bosh, this problem was completely solved! Turn on the outside ventilation button and there will be no smell! Many are worried that the service life is not as good as traditional filters! But health is more important to me! Even if we change it every 4 months as long as we are healthy why not? $20 isn't a big expense! Your purchase is worth it!
