Filters and Airborne Particles | Best Pick Reports

Buildup of pollen, dust, ragweed, and bacteria inside homes is common. Each time a door or a window opens, many new particles enter the home. If the particles are not proactively removed, they can begin to accumulate on furniture and in air ducts. Unfortunately, standard throwaway filters used by most heating and air systems only catch large dust particles and do little to stop most pollen, ragweed, and small dust particles. Certain advanced filtration systems, such as high-end pleated media filters and HEPA filters, are now available. Of course, as the efficiency of the filter increases, so does the price.
