Check for a charcoal filter behind the metal ones, because IKEA hoods in apartments are frequently recirculating and that filter is replaced rather than washed. Soak the metal filters flat and never put aluminium mesh through a dishwasher.
An IKEA hood arrives with an IKEA kitchen, built by Whirlpool and badged for the retailer, and it is the appliance in that package most likely to have been left alone entirely.
Recirculating is the common case
IKEA kitchens go into apartments in large numbers, and ducting to the outside of a multi-storey building is frequently impossible. So a great many IKEA hoods are recirculating: they filter the air and return it to the kitchen, using a charcoal filter behind the metal grease filters to deal with odour.
Charcoal is a consumable, replaced every six to twelve months, never washed. Washing one produces a wet obstruction that restricts airflow and does nothing for smell.
In practice a very large share of these still carry the charcoal filter that was fitted when the kitchen went in. If that is yours, the hood is doing nothing about odour and has not been for years, and no amount of cleaning the metal filters changes that.
Whirlpool parts, IKEA names
The hood is Whirlpool-built, so filters and components frequently cross-reference under that name. Since IKEA retires its Swedish product names every few years, measuring the filter and searching by dimension is usually faster than searching the name on the box it came in.
Flat-pack installation
An IKEA hood is fixed into particleboard cabinetry rather than into timber. It holds perfectly well, and it is worth being deliberate about anything that involves unfixing and refixing it, because board does not always take a screw as well the second time.
The general method is on our rangehood cleaning guide.

Should you do it yourself?
Do it yourself for the filters, and check today whether there is a charcoal one behind them.
