BlueAir 250E air purifier is the upgraded version of BlueAir 201; it captures pollen grains, dust mites, mold spores and pet dander. Cleans air in rooms up to 200 sq. ft (10 x 20 ft room).
The main difference between BlueAir 201 and BlueAir 205E is the 250E features an easy to use remote control and a blue digital display system that gives the user instant feedback of particle detection, air purifier speed and timer operation. The unit uses HEPASilent technology, a mixture of electrostatic and mechanical filter technology, which allows for delivery of cleaner air, at a faster rate, with less noise.
