How to choose
Noise figures
Noise is given in decibels. The AromaRoom runs at 22 dB in sleep mode on low fan speeds, the BLUEAIR runs as quietly as 19 dB, and the Honeywell runs as low as 20.81 dBA in sleep mode. Use the stated figure for the mode you will use each day, and check whether the figure is for sleep, low, or full operation.
Filtration and coverage
HEPA filtration captures small particles, and coverage figures show the room size a maker rates for a period. The AromaRoom circulates air twice per hour in a 323 sq ft room, the BLUEAIR cleans up to 1,138 sq ft in one hour, and the Honeywell circulates air once per hour up to 530 sq ft. Compare the time period with the room size, since a figure for one hour differs from a figure for twice per hour.
Controls and upkeep
Controls set how you change fan speed and mode, and upkeep covers filter replacement and reminders. The AromaRoom uses touch control with timer settings of 2, 4 or 8 hours, and the Honeywell has timer options. The BLUEAIR uses app control with air quality sensors and gives filter reminders through the app. The Honeywell uses AQSense auto mode with a filter change indicator. The AromaRoom filter needs replacement every 3 to 6 months.
