How to choose the right Air Purifier. CADR (Clean Air Delivery Rate) is the international standard for measuring the effectiveness of air purifiers. The higher the CADR, the higher the purification efficiency of the purifier. The Glory Days series is the premium line of Airthereal HEPA air purifiers. Based on a 360° cylindrical air intake system, air can be exchanged 5 times per hour in the living room. With its powerful purification performance and energy-saving feature, the Airthereal Glory Days AGH550 is the answer to all your air problems.


  • Powerful Performance: the AGH550 is powerful enough to completely clean and recirculate air every 30 minutes in a 1085 sq. ft. space or every 12 mins in a 450 sq. ft. space
  • Fantastic Filtration: take a deep breath knowing that your true HEPA filter is removing 99.97% of airborne particles; this includes particles like dust, pollen, smoke, and pet dander
  • Smart Auto Mode: our cutting-edge laser sensor counts and weighs airborne particles so your purifier only works as hard as it needs to; if the air quality in the room changes, the fan speed will automatically adjust to bring the air quality to a healthy level
  • Low Noise Level: with a near-silent noise level of 22dB you might forget that the air purifier is working right next to you to remove pollutants from the air
