This is a great air purifier that is small but it is very efficient.It has three settings to accommodate your air quality needs.This air purifier is so nice to have in a bedroom because it’s so quiet,I had to check to see if it was on.To my surprise is so quiet.It has a timer that will automatically turn of on the set hours. I also love how it draw all those unwanted odors in a quick second.There is also a night light at the base as well .This is a very high quality air purifier that works very well and efficient.The trendy sleek design also looks great with my decor.
