Filters and Airborne Particles in Houston | Best Pick Reports
According to the Environmental Protection Agency (EPA), the air inside the average home is 70 to 90 times more polluted than the air outside. Fortunately, modern technology offers solutions to indoor air problems.
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, which remove 99% of particles five microns or larger, and HEPA filters, which remove over 99% of particles 0.3 microns or larger, are now available. For comparison, the tip of a sharp pencil is about 200 microns. Of course, as the efficiency of the filter increases, so does the price.
