Air scrubber definition are a type of air cleaning device that combines both an air filter and a carbon bed to remove contaminants and chemicals from the air. These types of devices are usually used in industrial settings like during mold remediation projects, for welding and other manufacturing operations, or in homes that are undergoing remodeling and need help with indoor air quality issues.

They remove a wide range of pollutants including particulate matter, volatile organic compounds (VOC), and microscopic organisms. Particulate matter consists of dirt, dust, pollen, various types of chemicals, and hair and skin residue while VOCs are made up of a variety of odors, gases, and smoke. Lastly, microorganisms can include mold and mildew, viruses, bacteria, fungus, and pet dander.

Many of these pollutants can be harmful to humans. For example, mold and mildew can cause respiratory problems while VOCs like formaldehyde (which is found in a number of building products such as resins and glues, wood preservatives, paint, aerosol sprays, dry cleaned clothing, and pesticides) can cause irritation to the nose, eyes, throat, and lungs. Other pollutants like radon (which is an invisible, radioactive gas) can also be dangerous.

Because they can be used in a variety of different environments, air scrubbers can provide a number of benefits for homeowners. They can be particularly useful for families that suffer from allergies and other breathing-related conditions. They can also be helpful in home renovations to reduce the amount of dust and debris that gets into the air during construction, and in homes with pets to remove dander, odors, and other allergens.
