Price and rating as shown on Amazon when we collected them. Both change.
The MORENTO comes with a spare-filter offer built in: the listing names one pack plus two HEPA filters, on a machine quoting a CADR of 300 cubic metres per hour with Wi-Fi and Alexa control, four fan speeds, an auto mode, double-side air intake and real-time air quality monitoring, at 50 watts in a 3.61 kilogram body with a 24 decibel noise figure.
The two extra filters are the practical difference, because replacement filters are the running cost that people forget to add to the purchase price. Double-side intake is the airflow approach that lets a compact body move more air. At the time of collection it carried 1,565 ratings at 4.3 stars. Everything here comes from the Amazon listing rather than our own testing.
