When you shop for an air filter online, it's important to understand the two sizes associated with the product: the nominal size (which is a rounded number used to label the filter) and the actual size. Not being aware of these measurements can lead to consumers buying a filter that doesn't fit their oven or air conditioning system. Filter King offers hundreds of different filter sizes that can be used in various home systems, including the oven. If you have pets, children, or allergy sufferers in your home or business, it's recommended to replace filters more often to maintain higher indoor air quality and keep energy costs down.
To find the right size for your filter, start by rounding the measurements to the nearest whole number when you order new air filters. If your filter doesn't have the actual dimensions on the outside of the filter, you can measure it to get the correct dimensions. You can also use an air filter size chart to choose the right size and pay quickly. For example, a size of 20x30x1 may appear on the filter label, but if you measure the filter you will see that the actual size is smaller than the nominal air filter size of 20x30x1. It's important to note that inserting an incorrectly sized filter may cause it to bend, which may damage the filter or reduce its ability to function properly.
When creating a filter with this tool, you must use the “real” size of the filter, that is, the size shown by the measuring tape, and not a nominal filter size. When shopping for air filters, it's essential to understand both nominal and actual sizes. This will help you find a filter that fits your oven or air conditioning system perfectly. You can measure your existing filter or use an air filter size chart to find out what size you need. It's also important to remember that using an incorrectly sized filter may cause it to bend and damage it or reduce its effectiveness.
