What Furnace Filter Size Do I Need?

Figuring out the right furnace filter size for your oven can be a daunting task. But it doesn't have to be! The easiest way to determine the size of filter you need is to simply remove the current filter and look at its dimensions. Most air filters have their size printed on the side of the frame, usually in the form of “Length x Width x Depth”. For example, it may say something like “16x25x1”, where 16 is the length, 25 is the width, and 1 is the depth.

If your old air filter doesn't have the measurements printed on the side, you can measure it yourself. Changing your air filters regularly has several benefits. It helps to filter out harmful contaminants and keep your HVAC unit running efficiently. If your oven has an air filter in the return vent, changing the filter is easy, as it can be done from inside your home. If the return grille is in the ceiling, you may prefer to use a filter that has a slightly larger actual size, so that the filter doesn't fall on you when you open the vent. Using a furnace filter size finder makes it easy to find the correct filter size for your oven.
