What’s even better is that the machine automatically adjusts its fan speed depending on the current air quality.
  • Aera+ Mode – When set on Aera+ Mode, the machine runs at maximum performance to cycle the air as many times as possible in order to reduce the concentration of allergens, viruses, bacteria, and other air pollutants in the vicinity.
  • AeraSafe Antimicrobial Treatment – The AeraMax 300’s True HEPA filter is treated with AeraSafe Antimicrobial Treatment to prevent the proliferation of odor-causing bacteria, mold, fungi, and mildew on the filter. This helps to significantly prolong the service life of the HEPA filter.
