Air purifier. (Product Watch).Improvements to Blueair's Model 501 in-room air purifier An air purifier is a device which removes contaminants from air. Whilst marketed as being of particularly beneficit to allergy sufferers and asthmatics and to reduce second-hand tobacco smoke. have resulted in a more than 20% increase in its Clean Air Delivery Rate (CADR CADR Clean Air Delivery Rate CADR CARE Act Data Report CADR Child Abuse Death Review (Florida) CADR Constrained Anisotropic Diffusion Routing CADR Critical Airworthiness Design Review CADR Computer-Aided Design Reliability ). The new ratings give the Swedish-made and -designed Model 501 a CADR rating of 388 for smoke, 377 for dust, and 377 for pollen, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. tests by AHAM (Association of Home Appliance Manufacturers)--the higher the rating, the faster the unit filters air. Blueair attributes its high CADR rating to improvements made in the Model 501's ionization ionization: see ion. ionization Process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) by the removal or addition of negatively charged electrons. chamber and in the polypropylene filters, Improvements include increasing the number of ionization brushes in the air filter chamber from 4 to 10. This gives particles a stronger charge that leads to higher electrostatic filter efficiency and optimizes the functioning of the ionization chamber that now traps an even larger number of airborne particles. The redesign of the pleated mechanical fiber filters makes it easier for air to pass through the chamber, resulting in a higher level of filtration at a lower pressure drop for extra purification and less noise. Design, construction, performance, and quality features make the Model 501 quiet and energy efficient. Room capacity is 550 sq. ft. Like all Blueair units, the Model 501 comes with a 10-year limited warranty Limited warranty A warranty with certain conditions and limitations on the parts covered, type of damage covered, and/or time period for which the agreement is good. .
