I'm 62. I have severe asthma, and also emphysema.
I live in Oregon in the middle of one of the wildfire regions, and most summers there is 1 to 3 months with thick smoke. This year, 2026, it's worse than ever.
I've had this unit for 10 years, was recommended by my pulmonologist. I replace filters as needed.
I usually have it on all the time, on low. Now, for the fires, we have it on high 24/7, it's medium loud on high (almost silent on low).
But we keep it in a side room with the door open, so we don't hear it much, and it's still keeping the house clear. We don't smell smoke inside. But if we walk outside, it smells like we're sitting next to a campfire.
Well done. Good is a great company. I will keep using and recommending them.
