Filters are labeled with three-part dimensions, which are the length, width, and depth or thickness. The first number is the length, the second is the width, and the third is the depth or thickness. This number is usually shown on the side of the filter and is referred to as the nominal size. This nominal size is a rounded estimate used for consistency in production, as not all filters will be exactly the same size.
This nominal size creates consistency across the board, adding peace of mind and less confusion for consumers. It's also easy to compare different filter models. Air filters, oven filters, AC filters, and air conditioning filters are all the same filters. So if you need to find household air filter sizes, HVAC filter sizes, oven filter sizes or AC filter sizes or air conditioner filter sizes, you are looking for the same thing.
Using a table as an oven filter size finder makes it easy to find the correct filter size for your oven. Most air filters have their size printed on the side of the frame. The length, width and depth of the filter are measured in inches. For example, it will say something like “16x25x1”, where 16 is the length, 25 is the width and 1 is the depth. The most common AC filter sizes and oven filter sizes are 16x20x1 air filter, 20x20x1 air filter, 16x25x1 air filter, and 20x25x1 air filter. You can usually find the filter size of your air conditioner right in the size of the filter frame.
However, you can choose not to use the factory-installed filter grids and have an HVAC professional install an external filter grid to get a thicker filter. The first (and easiest) way to determine the size of your oven filter is to check the size of the old air filter. By using a properly sized filter and changing it regularly, you can experience cleaner indoor air and fewer system problems. Round to the nearest inch to create the nominal filter size, which is the measurement you will use when purchasing a filter. You can proactively clean the air and surfaces in your home by adding an air purifier in the duct that creates supercharged particles. Honeywell, Hunter and Whirlpool have several models of room air purifiers available, so it's important to check compatibility before purchasing a replacement.
Filters don't need to fit a “tight seal”, but you should be able to easily install and uninstall the filter effortlessly. These numbers relate to the standard size of your home's return ventilation grilles, responsible for controlling the movement of air to and from your HVAC unit. In addition, if there is any resistance to airflow caused by using a filter that is not the correct size, it can cause unnecessary stress on the HVAC unit itself, which could damage system equipment and increase energy bills. The MERV air filter rating is a measure of how effective an air filter is in removing particles from the air. On one hand this can greatly affect how much air pollutants leak out leading to poor indoor air quality. Now instantly improve air quality by choosing the right MERV rating because your family deserves only the best.
