✅ EXTRA THICK AND LONGEST LASTING: Simply Carbon filters provide superior odor protection, with a dense 0.4" activated charcoal layer and a leading 20-micron particle size. Avoid unreputable filters which are often too thin, make false quality claims and require more frequent replacing. ✅ FITS ALL STANDARD COMPOST BINS: Suitable for 99% of kitchen compost bins in the US. Easy installation with round and square cutting templates included to cut your filters to the exact shape and size that matches your bin (if required). The out-of-the-box size is 7.25” round. ✅ 2 YEARS OF ODOR PROTECTION (BEST IN MARKET): Protect your kitchen from odors for up to 2 years.

Using d2w technology, the bag is 100% biodegradable and environmentally-friendly.

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 for long lasting odor protection
Our filters are made extra thick (0.4" or 10mm) which is better for maximum odor absorption and to help the filters stay firmly in place without moving.

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.
