The Blueair 403 HEPA Air Purifier incorporates the Swedish design that reflects the successful styling and design concept of popular Blueair 503 air purifier. It is a helpful tool for combating allergy and asthma symptoms in smaller rooms as the 503 unit; the 403 air purifier is sleek, compact and quiet. To minimize the noise and maximize the airflow through the Blueair 403 model, Blueair engineers employ HEPA and combined it with internal electrostatic ionizers to charge the particulates and make them stick to the filter. The Blueair 403 cleans the air five times per hour.

The compact size of the Blueair 403 Air Purifiers makes them suitable in a variety of locations like bedrooms, bathrooms, laundry rooms, children’s rooms and small home offices. The Blueair Smokestop filter option is designed to address the reduction of odors such as tobacco smoke by the addition of more activated carbon. This is also an option that those with MCS should consider.

Blueair 403 Air Purifier Review

I can’t thank you enough for recommending the HEPA air purifier for my son Stephen. We had been struggling with his asthma for years. He had trouble breathing every day, many nosebleeds, and would cough himself awake almost every night until we added the 403 system to his bedroom. It has been a true God Send. It has given me my son back, and given him the freedom for the first time to really be a boy. He can now run, play, sleep, and do his daily activities without feeling the tightening in his chest. He hasn’t even used his inhalers even once since we added the system. His pediatrician at the Cleveland Clinic Foundation feels that it is the filtering system that has made such an impact on him, and so do I.

Thank you again for your help in creating a better environment for my son.
