How to Find the Right Size Filter for Your Home

Finding the right size filter for your home can be a daunting task. With so many different sizes and types of filters available, it can be difficult to know which one is right for you. Fortunately, there are some simple steps you can take to make sure you get the right size filter for your home. The first step is to measure the length and width of the filter.

If the filter is not a square, the smallest measurement comes first. Most air filters have their size printed on the side of the frame, so this should be easy to find. The length, width and depth of the filter are measured in inches. For example, you'll see something like “16x25x1”, where 16 is the length, 25 is the width, and 1 is the depth.

Once you have these measurements, it's important to remember that the actual size of the air filter will be slightly smaller than the nominal size. This means that if you have to force an air filter in or out, it's probably not the right size. We recommend that you start looking for a replacement air filter by reducing the depth of the air filter. When you change oven filters, it's also important to know what size oven filter you have.

If the filter is too large, it won't fit in the filter slot and you won't be able to replace the cover. Building a custom air conditioner or oven filter allows you to choose specific dimensions if the standard sizes don't work for you. Air conditioning filters are available in many different sizes, so it can be overwhelming if you're not sure what size filter you need. We recommend removing the existing filter and measuring the filter to confirm the actual dimensions.

A higher MERV rating means that an air filter is more effective at removing smaller particles from the air. Of course, this sounds easy when you hear the term “standard air filter size”; however, it's important to remember that standard sizes are usually half an inch smaller than advertised. Once you enter your filter sizes with us just once, not only do you not have to remember when it's time to change them, but you'll no longer need to remember those complicated sizes.
