If you have small rooms where indoor air quality is an issue, the Blueair 203 air purifier is an ideal system to consider. Like the Blueair 503 air purifier, the Blueair 203 uses ultra-quiet hybrid HEPA and electronic technology to keep the air clean at a low noise level. Air purifiers that do not use HEPA technology use other technology and design to help achieve higher filtration efficiency. These alternative technologies and designs can make the air purifier motor work too hard to push the air though the filter. This extra work translates to higher noise levels and higher electricity bills.

The Blueair 203 air purifier uses a highly advanced design that works efficiently with its HEPA filter to reduce noise. Blueair adds electronic brushes to their air purifiers and positions the brushes just before the HEPA filter and they charge particles in the airflow. This causes the particles to be electrically attracted to the HEPA filter where they “stick” as they go past. The result is a higher filtration rate, lower energy costs and reduced noise levels.

Blueair air purifiers are not only compact and efficient, terrific for smaller rooms like the laundry room, a baby’s changing area, the kitchen, and small bed rooms. The Blueair SmokeStop filter option is designed to address the reduction of odors such as tobacco smoke by the addition of activated carbon. This is also an option that those with Multiple Chemical Sensitivity (MCS) should consider.

Blueair 203 Air Purifier Review

YEA! 203 Air Purifiers! Thank you so much for helping me. I searched the web for hours trying to figure out which of the many air purifiers was going to help me. Then I saw the picture of the Mom and child on you web site and I decided to call. I have a beautiful, wonderful baby girl. We set up a changing area right outside the master bedroom where her crib is positioned until we move her into the nursery. For such a beautiful creature she is very smelly in the changing department. I needed something that would reduce the odor but not look like it was beamed down from a Klingon cruiser. The silver Blueair 203 filled the bill. I was so happy that I had called because the system was not even on the web site yet and Bonnie emailed me a picture. These air purifiers really work!
