Watch: How to replace a charcoal filter 

What is the Charcoal Filter and What Does It Do?

The trash compactor charcoal filter is a small, inexpensive part that makes a big difference in absorbing and neutralizing odors. It is made of carbonized charcoal enclosed in a plastic housing.

Here’s a quick look at what the filter does:

• Traps and absorbs foul-smelling gasses and odors from rotting garbage and food waste
• This prevents these unpleasant smells from escaping into the kitchen when the compactor runs
• Uses activated charcoal to effectively neutralize trapped odors
• Works in conjunction with the filter fan which pulls air through the filter during compaction

By continually filtering out offensive odors and smells, the charcoal filter keeps the air around your compactor unit fresh. It’s an important component for odor control.

When Should the Charcoal Filter Be Replaced?

The charcoal filter in your compactor should be replaced once a year or so. It has a limited lifespan and becomes saturated over time.

Here are some signs that it’s time to swap out that old filter for a fresh one:

• Strong, unpleasant odors around the trash compactor – This indicates the filter is no longer effectively neutralizing smells. Stale, rotting food odors may escape into the kitchen.
• Decreased compaction performance – A clogged filter can restrict airflow needed for proper compaction. You may notice trash is not compacting fully.
• The filter appears very dirty – Check the filter when you pull out the compactor drawer. If the filter is covered in debris and stains, it needs replacement.
• It’s been over a year – Even if the filter looks clean, replacing it annually helps ensure optimal odor control.

How to Replace the Charcoal Filter in a Trash Compactor

1. Unplug the trash compactor from the wall outlet, or shut off power at the circuit breaker if it’s hardwired. This ensures safety while working inside the unit.
2. Pull the compactor drawer all the way out. Remove any trash or liners to create a clean work area and prevent contamination when accessing the filter.
3. Look for the charcoal filter inside the compactor, usually near the top rear wall or behind a vented panel. If you’re unsure, consult the user manual for your specific model.
4. If the filter is behind a panel, remove it using a Phillips screwdriver or by releasing any tabs or clips. Keep the screws in a safe place for reassembly.
5. Slide or snap out the old charcoal filter carefully. Avoid damaging any surrounding parts. Dispose of the used filter according to local waste guidelines.
6. Position the new filter in the same orientation as the old one. It should fit securely without being forced. If it doesn’t fit, confirm that it’s the correct replacement part for your model.
7. If you removed a cover, reinstall it and secure it with the original screws or clips.
8. Slide the drawer back into place and check that it opens and closes smoothly.
9. Plug the compactor back in or turn on the circuit breaker. Run a short cycle to ensure the unit is operating correctly and the drawer is properly seated.
10. Most manufacturers recommend replacing the charcoal filter every 6 to 12 months. Write down the replacement date to stay on schedule for future maintenance.
