Whether you can see them or not, your home is filled with all sorts of fine particulates that can irritate your respiratory system. You can use furnace filters in order to help combat this issue in your home. There are many kinds of furnace filters to choose from out there. One of these is a HEPA filter. HEPA stands for high efficiency particulate arrestance. A HEPA filter is one of the best out there at filtering the air. A HEPA filter is made to catch particulates that are .3 micron in size. The fibers in a HEPA filter are woven together so tight that they can catch individual viruses and bacteria. This means your air will be as clean as it can possibly be as long as you keep up on changing your filter regularly. A HEPA filter is useful for someone with severe allergies because it catches so much more than a normal filter. HEPA filters are often used in hospitals and other areas that need to be ultra sterile but they can also be used in your home. Make sure you keep up on changing your filter regularly though because this filter is thicker and can restrict air flow easily if clogged which will cause your furnace to have issues.
