Can I use my LG air purifier while cooking? — LG Help Guide: Causes

We recommend turning off your air purifier while cooking. Grease and moisture from cooking can build up on the filter, reducing its lifespan and causing unpleasant odors. After cooking, open the windows to ventilate the room before turning the air purifier back on.

What to Check First

  1. Do not place or use the air purifier directly next to a cooking area, such as a gas stove or induction cooktop.
  2. We recommend turning off your air purifier while cooking. Grease and moisture from cooking can build up on the filter, reducing its lifespan and causing unpleasant odors. After cooking, open the windows to ventilate the room before turning the air purifier back on.
  3. Odor particles, fine dust, grease, and moisture produced during cooking can build up on the filter. This reduces the filter’s performance, shortens its lifespan, and causes unpleasant odors when you turn the air purifier back on.
  4. Grilling or frying food produces a large amount of fine dust, causing the dust level displayed on the air purifier to rise quickly. Running the air purifier alone in this situation causes excessive contaminants to build up on the filter. Always open the windows to ventilate the room first.
  5. Follow these steps to effectively remove cooking odors and fine dust, and to use your air purifier properly.
  6. Before you start cooking, turn off the air purifier to prevent contaminants from entering the unit.
  7. While cooking or immediately after, open the windows and turn on the kitchen exhaust fan or range hood to remove smoke and odors.
  8. After the room is thoroughly ventilated, close the windows and turn on the air purifier to remove any remaining odors and fine dust.
  9. If the issue continues after following these steps, contact LG Customer Support for further assistance. (Note: A service fee may apply if your product is out of warranty.).
