Let's take a look at the most common furnace filter sizes and where to buy them. You can usually find the size of your furnace filter directly on the filter frame. The right side of the filter will also include the actual size of the filter, which are the measurements of the filter by length, width, and depth. So when you need to find the sizes of home furnace filters, the sizes of HVAC filters, or the sizes of air conditioning filters, you're looking for the same thing.
The furnace filter size chart below lists standard size 1, 2, and 4 inch deep air conditioning filters for your air conditioning, heating, ventilation, and air conditioning filters. Incorrectly sized furnace filters can place excessive stress on your air conditioning system, damage it, and increase your energy bills. If you use a room air purifier and need to replace your filter, it's important to find the right size replacement HEPA filter. If not, the best way to determine the size you need is to measure the existing filter, assuming it is the correct size. Atomic has furnace filters checked by experts in the size chart for all brands of furnace filters, so you can trust that you will find the right OEM filter or save money on a compatible filter.
Filters are usually listed by nominal size, which is a rounded number based on the actual dimensions of the filter, which are called the actual size. If your air conditioning system uses a whole-house filter (they are near the central furnace or air conditioning unit), then the model number will most likely appear instead of the dimensions. When searching by brand such as Lennox or Carrier to find the size of a Carrier furnace filter by model number, you can use the Carrier filter size finder in the table above or search for Lennox size above and here's how you would do it. When it comes to finding out what is the most common size furnace filter for your home or business, it's important to know what type of system you have and what type of filter it requires. The most common sizes for residential systems are 1 inch, 2 inch and 4 inch deep filters. It's also important to note that some systems require special sizes that may not be available in standard sizes. To ensure that you get an accurate measurement for your furnace filter size, it's best to measure your existing filter or consult with an HVAC professional.
This will help ensure that you get a properly sized replacement that will fit correctly and provide optimal performance.
