Your vacuum cleaner should be considered to be one of your major appliances, as important as energy efficient refrigerators, washers and dryers, and furnaces. How does your choice of vacuum cleaner affect the indoor air quality, or IAQ, of your home? Which type of vacuum cleaner should you choose? There are three basic types: bagged vacuums, bagless vacuums, and Sealed HEPA vacuums.
Note: Advertising claiming loss of suction is not true. Only clogged passageways and filters cause a loss of suction. Electric motors never slow down or work less as they age.
