Blueair’s DustMagnet dual-function air purifier is the allergen-removing, dust-catching air purifier that blends right in. Patent-pending DustMagnet technology removes 99%* of airborne dust before it settles on floors and surfaces. Independently tested for performance as part of the AHAM Verified Program for room air cleaners, for a Clean Air Delivery Rate (CADR) of 216 for fine smoke particles, 274 for pollen particles, and 231 for dust particles. Only Blueair air purifiers use HEPASilent™ technology, delivering maximum filtration with minimum noise. Combining mechanical filtration with electrostatic charging of particles produces clean air up to 45% faster with up to 67% less noise than traditional HEPA filtration alone**. Sleek, Scandinavian design with a convenient table-top surface allows this purifier to compliment your aesthetic while working hard to clean your air. Place where it will be most effective at capturing dust without worrying about it cramping your style. Its combo-filters include a particle filter to remove dust and other fine particles and integrate carbon to effectively trap VOCs and light household odors from pets, cooking, and smoking. The two combo-filters in each purifier ensure optimal removal - one at the top and one at the bottom. Pair with the Blueair app to unlock smart features like Clean air ETA to count down the time until clean air and Welcome home function to automatically set your air purifier to standby when you leave home and back on to clean the air just before you return. Amazon Alexa and Google Home compatible with voice control. ? ? *CAPTURES 99% OF DUST BEFORE IT SETTLES: Removal of 99% of airborne dust particles (0.5-3 µm) in 20 min on highest fan speed based on AHAM AC-1 protocol; not applicable to larger particle sizes. ? **CLEAN AIR IN A MATTER OF MINUTES: Comparing CADR performance of Blueair models vs same models with only H13 HEPA. At similar CADRs, Blueair models achieved less noise than same models with only H13 HEPA. Noise refers to the dB(A) difference in acoustic power. Tested on Blue Pure 211+ Auto, DustMagnet™ 5400i, Protect 7400 series. Performance may vary. According to AHAM, air changes per hour (ACH) is the measure of the outside air volume added to a space divided by the volume of that space over a set amount of time.
