Oven extractor hood attracts dust

Wonder whether anyone can suggest a remedy please?

Steel extractor hood frame (source MFI c. 2 years old) all too readily attracts unsightly and very visible dust.

The hood is earthed via the power supply to the fan. It is built in - bolted to the wall and does not connect with anything else metallic. Extracted air is blown outside via a plastic tube enclosed in a plasterboard/timber frame.

The frame is painted (probably stove finished) dark brown.

Visible dust starts to settle within an hour or so of it being wiped clean.

Is this why unpainted stainless hoods are popular?

TIA for all suggestions.

Isn't the clue the words 'plastic tube'?

Possibly the air flow in the plastic tube is causing a build up of a static charge which is attracting the dust. Perhaps the cure is to wrap the plastic tube in cooking foil which is physically connected to an earth.

Perhaps the dust has a static charge?

There's a firm not far away that produces high efficiency agriculteral sprayers. AFAIK the metal atomiser head is at -2000Vdc and charges the droplets as they leave. There is minimum loss of the chemicals because the charged droplets are attracted to the (earthed) plants.
