File this under, things I didn't know i needed in my life, until I got one... this little air purifier sits perfectly on a night stand table in our bedroom. The noise level is not bothersome at all, it's comparable to when we have the fan running. I actually feel like my sinuses have not been as bad, I wake up in the morning and im not stuffed up like I was, my husband says his throat his not as scratchy either. Very easy instructions for care as well!
