Figuring out the right size air filter for your air conditioner unit can be a daunting task. But it doesn't have to be! All you need to do is find the filter size that fits your air return. You can usually find that size on the side of the air filter you already have in use. This size will be the nominal size, which means that it is rounded to its actual size.
If you have to force the air filter to install it, try a third-party oven filter or a custom-sized air filter with a slightly smaller actual size. Colorfil filters, originally created for NASA, help eliminate chemicals and odors at the molecular level, something that normal air filters cannot eliminate. Don't stack several small air filters on top of each other to fit in a larger air handler. Getting an exact fit is essential for having an effective air filter; an incorrect size won't fit and will cause the filter to stop working properly.
A four-inch or larger MERV 11 multimedia filter offers the most cost-effective air filtration for homeowners. Each of the fiberglass, polyester, washable, pleated and electrostatic filters offers different air filtering capabilities. Timely replacing your oven filter is much easier when you know what size air filter you need. To make sure it fits you properly, take out your current air filter and check the size printed on the frame.
Air conditioning filters are available in many different sizes, so it can be overwhelming if you're not sure what size filter you need. Air filters also help keep the furnace's coils and heat exchangers clean, which can extend the life of the oven and keep it running efficiently. If you live in an older house, with a non-standard size air return frame, you may want to use adhesive foam tape to protect the weather to slightly increase the dimensions of your favorite filter, or order a custom-sized air filter. In this case, you must round to the nearest whole number to determine the nominal size of the air filter.
While The Home Depot uses the FPR, the industry standard is to use the Minimum Efficiency Reporting Value (MERV) air filter classification system. Installing a smaller filter will allow unwanted contaminants to pass through and enter your home's air and air conditioning system. To sum up, finding out what size air filter you need for your AC unit doesn't have to be complicated. All you need to do is find out what size fits your air return by checking the side of your current air filter.
