Whereas the actual size is an exact measurement, normally in a smaller font, that depicts the filter's precise dimensions (ex: 15.50 x 19.50 x 0.75). All filters have both. Measuring Your Air Filter If your current air filter does not have a dimension listed on the frame, use a tape measure to record the width x length x depth to find the actual size. Then round these measurements up to the nearest inch to find a corresponding nominal size, which will be easier to locate when searching online. Why should I change my air filter? To maintain a healthy lifestyle, as breathing dirty air can put you at risk to develop asthma, allergies, and other respiratory ailments. Plus, old filters can cause system defects which may lead to unwanted expenses via energy costs and repairs. But this is subject to change based on filter size and variable factors for pet owners, allergy sufferers, homes with children, etc. But if you see a specific brand name on a listing, make sure it matches your unit model. How many air filters do I need? This varies for every customer depending on specific needs such as the number of vents in your home. Then just insert your new filter to match the direction of air flow, replace the cover, and turn the power back on.
