The more researchers learn about harmful particles and substances that exist in the air, the more air filters play an important part in society's long-term health. Strict air quality guidelines in many government and industrial circles make the use and continued innovation of air filters essential. Particularly beneficial is the use of air filters in domestic environments in which there are pets or excessive mold, mildew and dust that bring on allergic symptoms. Air filters help clean the air and remove these allergy-causing particulates, thus allowing home-owners and their families to breathe easier.
Air filters that deal with large particles and high velocities have large filter fibers, and likewise, air filters that deal with small particles and low velocities have small filter fibers. To ensure that an air filter will work properly in its intended application, make sure that the design, density of media and fibers and possible adhesive are taken into account before purchase.
Sometimes electric and chemical reactions within the filter itself help attract and remove harmful elements from the air. Filter efficiency is determined by a few different factors: the size of the filter fibers, the density of the fibers in the filter and the velocity of the air that moves through the filter.
