The often overlooked Range Hood Filter.

Manufactures recommend cleaning range hood filers every month.  This filter is designed to catch grease. Over time the grease buildup will decrease its effectiveness and reduce air venting on units that exhaust to outside. If hasn’t been cleaned in a while, or ever, then prepare yourself for a nasty project. The cleaning method below seems the most popular. I’ve also heard of adding vinegar to the water.

 

 

How To Clean a Greasy Range Hood Filter

What You Need

Ingredients
Very hot or boiling water
De-greasing dish soap
Baking soda
Non-abrasive scrub brush
Paper towels or dish cloth

Instructions

  1. Remove the filters from the hood: Most filters should easily slide or pop out of the underside of the hood. Mine had a metal loop I could grab to push the filter up and slide it out.
  2. Fill a sink or bucket with boiling water: The hotter the water, the more effective. Depending on how hot you can get the water from your tap, that might be good enough. For me, I boiled water in my electric tea kettle, and poured that into the sink.
  3. Pour in baking soda and dish soap: Pour a good squirt of de-greasing dish soap and 1/4 cup baking soda into the hot water. Swish around with a brush (not your hand because it's too hot!) until the water is nice and soapy.
  4. Put greasy filters in water: Submerge your greasy exhaust fan filters into the water. Make sure they're completely covered.
  5. Let them soak: Allow the filters to soak for 10 minutes.
  6. Scrub the filters: After soaking, take a non-abrasive scrub brush and scrub the filters. Add more dish soap to your brush if required while you scrub.
  7. Rinse and dry: Rinse the filters thoroughly in hot water and dry with a paper towel or clean cloth.
  8. Replace the filters and repeat as needed: Put the filters back into the hood, and repeat as needed! Cleaning the filters once a month is a good maintenance strategy.
