What are carbon filters 

Carbon filters are attachments that fit inside a range hood to filter the recirculate air in the kitchen. carbon filters are constructed of a carbon-based substance that collects impurities while also neutralizing grease and odors caused by your cooking.

A ducted range hood may be converted into a ductless hood with a recirculating kit, usually sold separately. These kits use mesh or carbon filters to filter the air.

What are carbon filters made of?

Carbon filters are made with activated carbon. Activated carbon is carbon that has been processed further to improve its ability to trap gas molecules.

It is first infused with hot air, carbon dioxide, or steam, which forms a lattice of tiny pores in the carbon, greatly increasing its surface area. This increases the number of places for molecules to become trapped, making carbon a far more effective filter medium. 

A gram of activated carbon could have hundreds of square meters of internal surface area, according to a paper published by the Ohio Environmental Protection Agency. Most activated carbon is also chemically treated to improve its ability to filter specialized pollutants.
