Drop the aluminium mesh filters and soak them flat in hot water with a non-caustic degreaser for an hour. Never put mesh in a dishwasher, where alkaline detergent oxidises it grey permanently. Then reach the impeller housing behind them, which is where the smell comes from.
Omega rangehoods arrive as the third item in a matched package, fitted alongside an Omega oven and hob in a project home, and they are almost always the appliance in that set that nobody has ever opened.
The general method for any hood, filters out, soaked flat, then the impeller housing behind them, is on our rangehood cleaning guide. Two things are worth knowing about this brand.
The filters, and where to get new ones
Omega uses aluminium mesh on the great majority of its fixed and undermount hoods rather than stainless baffles. Mesh is soaked flat and never put through a dishwasher, for reasons our rangehood cleaning guide covers along with the rest of the method.
The part specific to Omega is supply. Replacement mesh filters come through Residentia Group, which distributes the brand in Australia, or through the retailer that supplied the kitchen, and they are inexpensive. That matters more here than on a premium brand, because these hoods are frequently a decade old and on a filter that will not come clean the honest answer is replacement rather than another hour of scrubbing.
Because the same models went into hundreds of houses in a development, filter sizes are well known and generally stocked, so this is one of the easier brands to find parts for despite its modest profile.
The forgotten appliance in a matched set
Because Omega goes in as a three-piece package, the hob, oven and hood are the same age and get used at the same rate. What differs is attention.
The oven gets cleaned because it smokes. The hob gets wiped because it is at waist height and visible. The hood is above eye level, it looks clean from below, and it gets nothing.
The consequence compounds. A hood that has stopped extracting properly puts grease straight back onto the hob and the oven front, so the two appliances people do clean get dirty faster because of the one they do not. On a ten year old project home, the hood is reliably the appliance furthest behind and almost never the one mentioned when someone calls.
If you are booking the Omega oven or the Omega cooktop, the hood is worth adding.
Whole developments, one hood
Because Omega goes into project homes at scale, the same hood model is fitted across an entire estate. Filter sizes are therefore well known and generally stocked, which makes this an easier brand to find parts for than its modest profile suggests, and it means a problem you have is very unlikely to be unusual.
What actually goes wrong
Grey, chalky filters from a dishwasher cycle.
A distorted mesh frame from scrubbing too hard, after which grease goes straight past it.
Ten years without the hood ever being opened, which is the single most common finding on this brand.
A hum or rattle from an impeller loaded unevenly, which no amount of filter cleaning addresses.
Should you do it yourself?
Do it yourself for the filters, every couple of months.
Get someone in for the impeller housing, or if the hood has never been opened, which on a project home of any age is the likely case.
