If you are in the market for a range hood, you may have heard the term “carbon filter” a few times, but what are carbon filters? And do you need them for your range hood?<\/strong><\/p>\n\n\n\n In this article, you will learn what carbon filters are, what they are made of, how to replace them, and how to choose a new one, if necessary, for your range hood.<\/p>\n\n\n\n Carbon filters (also known as charcoal filters) are attachments that fit inside a range hood to filter the recirculated air in the kitchen. They collect impurities while also neutralizing grease and odors caused by your cooking.<\/strong><\/p>\n\n\n\n Carbon filters (also known as charcoal filters)are attachments that fit inside a range hood to filter the recirculated air in the kitchen. Carbon filters are carbon-based substances that collect impurities while neutralizing grease and odors caused by your cooking.<\/p>\n\n\n\n They are inexpensive, lightweight, and very easy to replace. Unfortunately, carbon filters are not washable and always need to be replaced. <\/p>\n\n\n\n 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.<\/p>\n\n\n\n\n\n Carbon filters are made with activated carbon. Activated carbon is carbon that has been processed further to improve its ability to trap gas molecules.<\/p>\n\n\n\n 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. <\/p>\n\n\n\n According to a paper published by the Ohio Environmental Protection Agency, a gram of activated carbon could have hundreds of square meters of internal surface area. Most activated carbon is also chemically treated to improve its ability to filter specialized pollutants.<\/p>\n\n\n\n Charcoal filters are required when using the recirculation (not venting) setting on your range hood. However, charcoal filters are unnecessary if the range hood is vented.<\/p>\n\n\n\n The purpose of charcoal filters is to neutralize unpleasant odors produced while cooking. The odor-causing fats and oils in the air will be drawn into the cooker hood and filtered out using the charcoal element. After the air passes through the filter, it is cleaned and filtered before recirculating into the room.<\/p>\n\n\n\n There is nothing to absorb these volatile oils and odors except charcoal filters. Since the stale air holding them is recirculated, it will not be useful in masking unpleasant odors in the kitchen.<\/p>\n\n\n\n But if your range hood is set up to exhaust outdoors, you may skip the charcoal filter. Odors in this air will not be recirculated. Thus, there is no need to remove them. Instead, a vent carries it outdoors.<\/p>\n\n\n\n While ducted range hoods will always be the best solution, carbon filters are an effective alternative for those who can not vent to the outside. However, carbon filters are also less efficient than metal filters because they create more resistance for the air to pass through.<\/p>\n\n\n\nWhat is a carbon filter? <\/h2>\n\n\n\n
