People suffering from asthma, allergies and other respiratory-related symptoms will find air purifiers useful because they clean indoor air. Air purifiers are available in several varieties specific to the particular airborne contaminant you are combating, such as dust, smoke, pollen and chemicals.
Air Purifier Types
Different types of air purifiers include HEPA, activated carbon, electronic, UV and ozone.
According to the U.S. Environmental Protection Agency (EPA), humidifiers are commonly used to ease symptoms brought on by the common cold by adding moisture to the air and to alleviate the effects of winter heating in the home.
Different types of humidifiers include ultrasonic, impeller, evaporative and steam vaporizer.
Portable room air purifiers and humidifiers are available to meet the needs of a specific-size room; both can be installed to service an entire home through an HVAC system.
