Knowing the size of your air filter is essential for ensuring that your home's air conditioning system is running smoothly. But how do you read air filter dimensions? In this article, we'll provide a step-by-step guide to help you measure the length, width, and depth of your air filter accurately.On all filters, you'll find three numbers (e.g., in the United States, these measurements will always be in inches). Step 1: Measure the length and width (L x W). If the filter is not a square, the smallest measurement will be the first. The filters are labeled with three-part dimensions.
The first number is its length, the second its width, and the third its depth or thickness. Timely replacing your oven filter is much easier when you know what size air filter you need. In some cases, the length and width are interchangeable, but you'll always have to make sure you measure those three specific dimensions of the air filter or oven filter. Placing a large filter where it doesn't belong can damage the air conditioning system and not clean the air properly. There are literally thousands of sizes of air filters, and manufacturers of heating, ventilation and air conditioning systems are encouraged to make it as complicated as possible, so you have to pay for expensive replacements.
Installing a smaller filter will allow unwanted contaminants to pass through and enter your home's air and air conditioning system. However, you can choose not to use the factory-installed filter grilles and have an HVAC professional install an external filter grille for a thicker filter. This is the easiest and most obvious way to find out the size of an air conditioner filter, but not all filters have the size measurements listed on them. Round to the nearest inch to get the nominal filter size, which is the measurement you'll use when buying a filter. The gaps will allow dust, dirt, and germs to bypass the filter and possibly re-circulate to the air in the house.
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 that you start your search for replacement air filters by limiting yourself to the depth of the air filter. Filters should be changed every 30 to 90 days, depending on the type and efficiency of the filter. Measuring your air filter dimensions correctly is essential for ensuring that your home's air conditioning system is running properly. With this step-by-step guide, you'll be able to accurately measure your air filter's length, width, and depth so that you can purchase a replacement that fits perfectly.
