Home composting is a great way to get rid of trash and make garden fertilizer that is good for you. But for the best results, you need the right compost bin and parts for it, like a good compost bin filter. We’ll talk about why a compost bin filter is important and how to pick the best one for your natural home composting setup.
Why Use a Filter in Your Compost Bin?
A filter in your compost bin serves a couple of crucial purposes:
-
It helps control odors. As organic matter decomposes, gases are released that can cause unpleasant smells if allowed to escape unchecked. A filter traps these odors inside the bin.
-
It regulates airflow. Aerobic bacteria need oxygen to break down the compost. Too little air flow and the compost becomes anaerobic, slowing the process. A filter moderates airflow so oxygen gets in without letting excess moisture escape.
-
It prevents flies and insects. Fruit flies and other bugs are drawn to the smell of food waste that is breaking down. A filter blocks them from entering while allowing air circulation.
-
It contains mess. Without a filter, bits of compost can get pushed out of the bin when you open the lid. The filter keeps everything neatly inside.
Filter Options for Natural Home Compost Bins
There are a few different types of compost bin filters appropriate for eco-friendly home composting
-
Charcoal filters: charcoal is very porous and really soaks up smells. It also does a good job of controlling airflow. Charcoal filters for cabinets, furnaces, or activated charcoal in a bag with open mesh can all work.
-
Landscape fabric filters: Landscape fabric is designed to allow air and water to permeate soil while blocking light. It can be secured over vents or openings to control airflow.
-
Wire mesh: A simple wire mesh screen over vents keeps flies out while letting air flow. Opt for stainless steel or galvanized wire that won’t rust.
-
Burlap: Similar to landscape fabric, burlap is breathable while providing filtration. It’s biodegradable too.
-
Nylon window screen: Fold nylon window screen over vent openings to keep out insects. Make sure it’s securely attached.
Tips for an Effective Natural Home Compost Bin Filter
To get the most out of a compost bin filter, keep these tips in mind:
-
Make sure it fits snugly over any vents or openings so odors and insects can’t sneak by. Secure with staples, zip ties or velcro.
-
Check periodically that it remains intact. Replace filters that get damaged or degrade over time.
-
Use wire mesh or landscape fabric over large gaps for structure, then layer charcoal or burlap over that for added odor control.
-
Have separate filters for warm weather and cold weather. Increase ventilation in winter by using mesh or fabric with larger holes.
-
Store a supply of replacement filters so you always have them ready when needed.
-
Spot clean or hose filters down periodically if they get clogged with debris. Let them dry fully before replacing.
-
Make your own low-cost filter using charcoal from the hardware store and an open weave bag.
DIY Natural Home Compost Bin Filter
Want to make your own customizable compost bin filter? Here’s a simple way to do it:
Supplies needed:
- 1 pound activated charcoal
- Old cotton pillowcase or burlap sack
- Rubber band or twine
Instructions:
-
Cut a square of fabric a few inches larger than your compost bin vent. Burlap works well since it’s breathable. For a standard 11″ by 11” vent, cut the fabric 14” by 14”.
-
Place the activated charcoal in the center of the fabric square. Pull the corners up and tie them together with twine or a rubber band to create a small sachet or bundle.
-
Use a ladder stitch, running stitch or whip stitch to securely sew the edges together once tied. Make sure no charcoal can escape.
-
Place the charcoal sachet over the vent openings on your compost bin. You may need to use a few staples to keep it fully secured.
-
When the filter gets dirty, untie it and dump out the old charcoal. Refresh with new activated charcoal and re-sew.
This reusable charcoal filter eliminates odors, contains flies, and costs almost nothing to make yourself. Change the charcoal regularly for an effective DIY natural home compost bin filter.

Follow charcoal filter replacement recommendations
Charcoal filters have a lifespan and effectiveness, so it’s important to follow the manufacturer’s recommendations for replacing them. The frequency of replacement may vary depending on usage and the type of filter used. Typically, filters are replaced every few months or when they become saturated and lose their effectiveness.
I replace my filter every 3-6 months depending on how much we use the bin. I tend to flip it once before tossing it to make it last a bit longer. The charcoal filter can also get gross more quickly if food scraps touch the filter. Thus, emptying the bin before it overflows helps elongate the life of the charcoal filter.
Store charcoal filters properly
If you purchase replacement charcoal filters in advance, store them in a cool, dry place away from moisture and strong odors. This will help preserve their absorption properties and ensure they remain effective when needed.
We store our extra filters in a drawer under our counter with other kitchen accessories. Whenever I buy them in bulk, I keep them in the plastic bag they come in. They last for years that way.
