Why a clean grease filter matters on a Chef rangehood

The metal filter is the first thing cooking fumes hit. It traps grease droplets before they reach the fan and ducting, which keeps the motor cleaner and cuts the fire risk from built-up fat. Over time filters get bent, lose their frames or become so clogged that even a good soak will not clear them. A damaged or blocked filter shows up as weak extraction, steam and cooking smells hanging around the kitchen, grease dripping from the hood or a fan that sounds louder than it should. A fresh filter brings back the airflow the hood was designed for.

Measure before you swap the filter

Turn the rangehood off and let the hood and filter cool. Measure your old filter first, as the 784 x 193mm size is the quickest way to confirm a match. Most filters release with a catch on one edge, so support the filter as it drops down and lift it out. Clip the new one in until the catch locks. Wash metal filters regularly in warm soapy water so they keep doing their job.

Questions about this part

How often should a metal rangehood filter be cleaned?

It depends on how much you cook, but many households wash metal filters every month or so. Soak them in hot soapy water, or use the dishwasher if the filter is marked dishwasher safe, and dry fully before refitting.
