A few years ago there were really bad fires here, I'm talking ash covering cars, if you went outside you would get ash on you, the sky was always dark no matter the time, it was terrible. I have asthma and I could not leave the house if I didn't have to because if I would go outside I felt suffocated. Anyways at the Targets around here all the air purifiers were sold out so my Mom ordered the Ionic Breeze online, I think it was around $100. Before we got it, the house was smokey, we plugged it in, a couple hours later you couldn't smell smoke unless someone opened the door. So it really works.
End of long story haha.
