Air Purifiers

If air fresheners give the illusion of cleanliness, air purifiers don’t help much either. Worst of the lot are ionic purifiers; while removing dust with negatively charged ions, they produce ozone in the process. According to the EPA, ozone can worsen asthma and cause chest pain and throat irritation. Purifiers with high-efficiency particulate air or HEPA air filters used in conjunction with coal-based filters are effective at reducing some pollutants. But particles may be too big or too small for even these filters to catch. The best-rated air purifier according to ConsumerSearch.com, IQAir HealthPro Plus, costs $899.
