A bedroom’s air quality is important for getting a good night’s sleep. Many people rely on air purifiers to rid their sleeping quarters of dust mites, microbes and other airborne particles, as well as bacteria, viruses, volatile organic compounds (VOCs), and unpleasant odors. Air purifiers are particularly beneficial to people with allergies and/or asthma. Air purifiers sold today fall into four general categories based on the type of filtration used: HEPA, activated carbon, ionizer, and ozone; some purifier models utilize more than one of these systems, as well as UV technology. Although high-end air purifiers can cost hundreds of dollars, shoppers can usually find models for $100 or less.
