Hi folks!
I hope you're doing great!
My friend is asthmatic, I'm not. I signed up here to ask your wise and experienced advice. My friend turns 25 next month, and I decided to gift him an air-purifier. He had one, but it's gone.
Which purifier is the best for asthmatics? I know, that there are special air-purifiers for this case, so I need one of them. Thanks!
