We caution the use of common "bulk buy" filters which are often too thin, wrong size, have less carbon density and require more frequent replacing. The bitterness of poor quality remains long after the sweetness of low price is forgotten.

What makes Simply Carbon filters the industry leading for home composting?

Increased carbon density
Simply Carbon filters are infused with additional activated charcoal to better absorb odors and last longer than cheaper alternatives.

Extra thick to last longer and stay in place
Thicker filters improve odor absorption and ensures the filters stay firmly in place without moving or falling out.

Cutting templates included for all common bin sizes and shapes
You don't want to purchase filters only to find they don't fit your bin! These will fit any compost bin up to 7.25" filter size.

Resealable packaging to retain maximum shelf-life
Most filters in the market do not come with resealable packaging, and in-fact come inside a polyethylene plastic bag. Our resealable packaging is 100% biodegradable and can also be recycled with no harm to the earth.
