How to choose
Compare maker coverage figures first
Coverage is the figure that separates these picks: the maker lists 1,200 sq ft for the AIRTHEREAL and 1,035 sq ft for the Econika. Measure your room first, then match it against the figure the maker gives for the unit you are considering. A figure from one maker does not transfer to another unit, so compare the stated figures side by side.
Filter stages and humidifier type
The Econika uses a 6-stage filter, the AIRTHEREAL uses 3-stage filters, and the BLUEAIR uses HEPASilent filtration with a wick. The AIRTHEREAL humidifier module is evaporative and detaches for standalone purification, while the BLUEAIR uses 360° InvisibleMist and an auto wick dry mode. Choose the filter setup and humidifier type that match the features you want.
Controls, runtime and upkeep
The Econika comes with a remote control. The AIRTHEREAL uses touch control with a color-coded air quality indicator. The BLUEAIR adds app control. The BLUEAIR has a 48-hour runtime, and its pump indicator alerts the user when a refill is needed. Check the tank, filter and refill setup of the unit you choose before you buy, so the upkeep fits your routine.
