Air purifiers for asthma, 11-20 m2 room, True HEPA, CADR rating 200-299 m3/h

  • An air purifier for asthma relief must be capable of trapping small particles such as pollen, pet dander, pollution and dust and be powerful enough to drag all of the air in the room through the filter a minimum of 5 times an hour (ACH) for it to be genuinely effective.  To get around 5 air changes per hour in your room measuring between 11 and 20 m2  you need an air purifier with a clean air delivery rate (CADR) in the range of 200-299 m3/h.
  • To get the maximum benefit from an air purifier it should have a True HEPA (H13) or medical-grade True HEPA (H14) filter.
