The saying ‘you don’t know what you don’t know’ applies so fittingly to people’s relationships with their range hood filters. In 2010, the New York Times ran a story in which Robert Schwartz, an interior designer had this to say about vents: “I’ve gone into kitchens 20 years old, and people have never cleaned their filters.” It’s time to give these ventilation superstars the limelight they deserve, here is your 10-step deep cleaning strategy.

  1. Filters trap oils, cooking fumes and many pollutants, so in order for them to work properly you need to wash them – regularly.
  2. If you haven’t washed your filter(s) in more than a year, fill your sink with 12 cups of boiling hot water. Simply boil a full standard kettle twice. Add 1 cup of white vinegar and a few drops of dishwashing soap.
  3. Soak the filters in this bubble bath for an hour, then drain the water.
  4. Next, put a few drops of dishwashing soap on an old toothbrush and meticulously scrub both sides of the filter.
  5. Repeat steps #2 and #3 all over again.
  6. Now, put a few drops of dishwashing soap on a wet microfibre cloth and give the filters a sudsy car wash treatment.
  7. Once you’ve washed away all the grime, and rinsed away all soap residue, load them in the dishwasher.
  8. Run them through the dishwasher on the highest temperature setting and if you’ve got it, use the sanitizing option too.
  9. Remove the filters from the dishwasher and pat them down to remove excess water, then re-install.
  10. Moving forward, set an alarm on your phone to wash your filters in this deep cleaning bubble bath or the dishwasher once a month.
