Air treatment products control indoor air quality. Air cleaners (also known as air purifiers) remove or deactivate airborne pollutants and neutralize odors in schools, offices, commercial spaces, and homes. Negative air machines (also called air scrubbers) remove contaminants or pathogens from indoor air in abatement, restoration, demolition, and containment applications in medical or industrial facilities. Dehumidifiers remove moisture from the air to dry indoor spaces and help prevent or stop the spread of mold. Humidifiers add moisture to the air in indoor spaces to help occupants breathe more easily, make indoor air feel warmer, minimize static shocks, and keep wood surfaces and furniture from drying out.
