Carbon Filter
Made of activated carbon, also called activated charcoal, carbon air filters trap those nasty smells generated form food waste.
Activated carbon is a carbon-rich solid that is derived from biomass. Earthy's activated carbon has millions of tiny pores in the activated carbon that increase the total surface area, therefore allowing more gases to be captured. The greater the surface area the greater the adsorption capability of the activated carbon. Essentially, it works like a sponge that can absorb and trap gaseous molecules.
In comparison to the other filter options available in the market (eg. HEPA or UV), activated carbon filters may not be as efficient because they don’t have a glass fibre filter. But Enrich filters have been designed to ensure it is one of the most environmentally sustainable options and accounts for the least amount of waste.
Based on our testing filters should be changed every 2- 4 weeks depending on usage.

How do carbon filters work?
Carbon filters trap odours through a process called adsorption, which occurs when molecules attach to the outside of a surface, rather than being soaked into it. The more porous the activated carbon, the better, as this will increase the amount of surface space available for contaminants to latch onto when air passes through the filter.
Any Other Questions?
Enrich filters use activated carbon to trap moist air, remove gases from circulation and reduce unpleasant smells.
They are designed to filter out odours, pollutants, and hydrocarbons such as volatile organic compounds (VOCs) from the air via adsorption (ad-sorptionnotab-sorption). Adsorption is a distinct process whereby compounds in the air react chemically with the activated carbon and adhere to this solid material’s surface. This causes the compounds to be trapped in the filters (stuck to the carbon) instead of released into the surrounding air. The Enrich filters also absorb moisture and therefore decrease the amount of condensation that would otherwise occur on surfaces behind/beside Enrich's exit airflow.
All in all, the Enrich filters ensure that the air coming out of your Enrich is less smelly, purified, and safe.
Earthy Enrich will work without replacing the filters, however, after 3-4 weeks you will start to smell odours coming from the machine.
