The Coway airmega is probably the best home purifier you can get at the moment
the only thing that actually helped me sleep was a Coway Mighty in the bedroom running 24/7.
Coway airmega is the absolute best imo
I've been running a Coway Mighty in my bedroom for the past six months and it's made a huge difference.
Id recommend the Coway Airmega mighty. Its pretty quiet and has helped a lot with my allergies.
