I find that I sleep better when using the air purifier in the bedroom overnight. The unit is very quiet and seems to produce a sense of well being. The downside for me is that I cannot find replacement filters at a reasonable price compared to other brands. In fact I only found one source on the WWW which I think was the manufacturer. This is a problem since quite frequent replacement is recommended by the manufacturer.

I got it because I live in Canberra and there has been hazardous air quality due to bushfire smoke. I only realised that it doesn't filter out pm2.5 particles after I bought it. (It doesn't have a HEPA filter). I feel like an idiot for not doing my research properly. That's on me. But I don't really see the point of an air purifier that doesn't filter pm2.5. It does make the air smell less smokey, though, so at least it does something.

not recommend! You better go for a bit more expensive one and get the better result! The fan monitor is like they use a kid travel little fan and the filters are a little one and not HEPA!
