Review on AirTechnik CF12157 Activated RX450HL Highlander by Leo Govindan

I just spent the weekend in a cab in Tahoe and was in the car for about 30 hours at a time. The worst forest fire smoke in recent history! The fan was circulating air all the time, and the car wasn't bad at all. Whenever I went to eat or go to the toilet, it was awful! Immediately my eyes started to burn, my throat started to tickle. The air quality index was over 500 ppm. Unhealthy for all groups! Perfect timing as I changed my filter a few weeks ago :)
