Soak the filters flat in hot water with a non-caustic degreaser, never a dishwasher if they are aluminium mesh. Filters frequently cross-reference with Westinghouse and Chef, so measure the equivalent part before concluding a replacement is unavailable.
Electrolux hoods are unremarkable in the best sense and the general method, filters out, soaked flat, then the impeller housing behind them, is on our rangehood cleaning guide. Two things about this badge are worth knowing.
Parts cross-reference across three badges
Electrolux, Westinghouse and Chef are one group, and their hoods frequently share filter dimensions and motor assemblies. Hood filters lose their labels and model stickers fade in a warm greasy environment, so replacements are usually listed by dimension rather than badge.
If an Electrolux-badged filter seems unobtainable for an older hood, measure the equivalent Westinghouse or Chef part before giving up. See how to clean a Westinghouse rangehood.
Hob2Hood changes the interval
Where an Electrolux hood is paired with an Electrolux hob by infrared, it starts and adjusts automatically. It runs far more than a manual hood and loads correspondingly faster, and the thing that normally reminds someone to clean a hood, reaching up to switch it on, has been designed out. Six to eight weeks is realistic on that pairing.
Ducted or recirculating
If the hood returns air to the kitchen rather than ducting outside, it has a charcoal filter behind the metal ones. Charcoal is replaced every six to twelve months and never washed.
The slide-out models
A good share of Electrolux hoods are the slide-out type: a shallow unit under a cupboard with a visor that pulls out over the hob and pushes back flush.
The visor runs in side channels, and those channels fill with a mixture of fat and dust that makes the slide stiff. People then stop pulling the visor out, which means the hood runs with its intake half covered, extracting very little while appearing to work normally. It is a quiet failure that can persist for years.
If your slide-out has become stiff, that is not the mechanism wearing out. Clean the channels with a cloth and a non-caustic degreaser, dry them, and it will usually move freely again.
There is a second consequence. On a canopy hood you look up at a greasy filter every time you cook, which is its own reminder. On a slide-out you see a clean flush front and the filter behind it is out of sight entirely, so these get left considerably longer than hoods that are visible.
Where the noise comes from
An Electrolux hood that has become loud has almost always developed an imbalance rather than a fault. Grease builds unevenly on the impeller blades, the fan is no longer running true, and what was a hum becomes a rattle. Cleaning the filters does nothing for it because the imbalance is behind them.

Should you do it yourself?
Do it yourself for the filters every couple of months.
