How to Choose the Right Size Furnace Filter

When selecting a furnace filter size, it's important to consider both nominal and actual sizes. Make sure that the size of your chosen filter is slightly smaller than the measurements of your filter compartment.

How to Choose the Right Size Furnace Filter

When it comes to furnace filters, there is no one-size-fits-all solution. Most oven and air conditioner filters have a standard 1-inch thickness, but some are thicker and can withstand more build-up, trapping more particles than a standard filter. However, thicker filters can restrict airflow, leading to system and air quality problems. It's important to understand the difference between nominal and actual filter sizes when selecting the right filter for your home. At Filterbuy, we classify filters according to their nominal size, making it easier to navigate and search for the filter you need.

We offer hundreds of different filter sizes that can be used in various home systems, including the oven. When selecting a filter size, make sure it is slightly smaller on each side of the groove in the filter housing, allowing you to slide it in and out with ease. It's also important to note that the sizes of the air conditioner and oven filters must be smaller than the measurements of the filter compartment. If you're having trouble finding the right size filter at your local home improvement store, 70% of what Filterbuy sells is out of the 10 most common air filter sizes. On our website, first select the type of product (oven filters), and then select the nominal oven filter size (thickness) of your filter. Choosing the right furnace filter size may seem simple, but there are some common pitfalls that can be misleading.

Filters don't need to have a “hermetic” seal, but you should be able to install and uninstall the filter easily and without problems. With Filter King, you can quickly find and purchase the right size filter for your home. When selecting a furnace filter size, it's important to consider both nominal and actual sizes.
