How to replace your carbon filter

Heads up that this might be a little dusty. Consider doing this outside or over a trashcan.

Mill Essential

  1. Remove the filter drawer in the back of your Mill. 
  2. Turn the hand screws counter-clockwise and remove the green filter lid.
  3. Empty out the spent charcoal into the garbage.
  4. Open your filter replacement bag and pour the entire bag into the drawer. We recommend doing this step over a kitchen sink - as it can get a bit dusty. 
  5. Gently shake the drawer back and forth to make sure the charcoal is level. 
  6. Then, toe-in the green filter lid into place and use turn the hand screws clockwise to secure the lid. 
  7. Slide the drawer back into your Mill. Make sure it clicks into place.

Replace and recycle the activated charcoal in your canister

  1. Open the rear door of the Mill.
  2. Remove the old canister and follow directions below to recycle.
    • Pop open the lid (like paint can) using a flat head screwdriver or butter knife.
    • Put the spent activated charcoal in the garbage. We know this doesn't feel quite right, but it's okay! Burying activated charcoal is a form of carbon sequestration, so putting it in the trash won’t add emissions.
    • Peel off and dispose of the foam along the top edge.
    • Place the metal canister and lid in the recycling.
  3. Take off the packaging and stickers from the replacement canister.
  4. Put the new canister upright in the drawer and slide it back into the Mill.

Swap your old filter for your new one

  1. Press the back panel of your Mill to access your odor filter.
  2. Remove the old filter from your Mill and place it aside. Be careful — it might be a little dusty.
  3. Grab your new carbon filter and remove it from the shipping box. It may look a little pre-loved. That’s because it was used by another Mill customer and we refurbished it for you.
  4. Peel off the sticker completely from top to bottom - you may want to do this over the sink as it can be a little messy.
  5. Place the new canister in your Mill in the same location as your old canister.
  6. Replace the back panel, snapping it into place.
