Blueair 503 HEPA air purifiers are the original model that took the world of allergy and asthma sufferers by storm. This system is attractive enough to fit in any home or office decor and because it's on casters can be easily moved from one room to the next. Blueair air cleaners quietly cleans a large volume by employing internal electrostatic ionizers making the system both a HEPA and Electrostatic air purifier. This allows a more open HEPA element to be used while still retaining the effectiveness of world-class air purifiers. There are five air exchanges per hour with this air purifier.
