What to know before buying
Listing details to confirm
Listing details are contradictory or inconsistent: the title and feature claims give 90 m³/h, while the description gives 90m3/hr and 20 litres per second. Noise is listed as both 39 Decibels and 42dB(A), and power as both 19 watts and 20W. It also lists Touch controls and Wall Mount only in the technical details, while the feature text says wall or ceiling mounting. Confirm the details for the selected listing and installation.
