The Manrose MF100T sits at number 4 in this guide, and it is the odd one out here: it is an inline mixed flow fan that mounts inside the duct rather than on the wall or ceiling. That is why its numbers sit in a different league — the listing quotes 68 litres per second, or 245 cubic metres per hour, against the 78 to 98 cubic metres per hour that the axial 100mm fans in this guide list. Same 100mm duct, different job.

Its noise figure is 25 dB(A) at 3 metres, so this one, like the other fans here that name a distance, tells you where the measurement was taken. What it does not do is agree with itself. The specification table on the same listing says "Battery Powered", "Remote Control" and "Control Method: App", while the description says Class II double insulated with no earth required, a 25-watt power consumption and a built-in run-on timer. Everything on this page comes from the Amazon listing, not from any test of ours.
