Air purifiers for asthma, 26-30 m2 room, True HEPA, CADR rating 400-499 m3/h, night mode

  • 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 26 and 30 m2  you need an air purifier with a clean air delivery rate (CADR) in the range of 400-499 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.  
  • For a bedroom or baby room, you may want to use a quieter air purifier that comes with "night" mode.  Air purifiers with "night" mode run quietly in the background allowing you to enjoy clean air while you sleep.  


Below is the selection of suitable air purifiers tailored to meet your needs and sorted by price in ascending order.
