This Blue Pure 511 Air Purifier is perfect to use in bedrooms.  Nice and small and stylish…good for up to 180 square feet.  I use this in my sons room after we had the home painted. It kept the air in his room cleaner and is so very quiet, even on the highest setting.  Very lightweight and easy to keep clean and change the filters. Very easy to use, and eliminates so many harmful and toxic chemicals.  Definitely a good addition to have in every room,
