Are you looking for the most common air filter sizes? If so, you've come to the right place. Filters are labeled with three-part dimensions, with the first number being its length, the second being its width, and the third being its depth or thickness. The easiest way to identify the size of your air conditioner filter is to remove the existing filter from its slot and examine the filter frame. Usually, the filter size is printed along the edge of the filter frame.
Note that the size shown in bold type on the filter frame is the nominal size of the filter, which is likely to differ from its actual size. If the actual dimensions do not appear in small print on the filter frame, we recommend measuring the filter to double check it. In this case, you'll want to round down to the nearest whole number to determine the nominal air filter size. The actual size of the air filter should be 0.25 -0.5 smaller than the slot or frame itself.
The slots of the HVAC unit are usually located near the bottom of the air conditioning handling unit. It's best to have some wiggle room in the slot of the HVAC unit, so you can easily slide the filter in and out without it bending or breaking. If you have to clog the air filter to install it, you should try a different brand of oven filter or a custom sized air filter with a slightly smaller actual size. The central air return grilles are usually located on the ceiling of the hallway or on the wall of the hallway in your house.
If the return vent is on the ceiling, you may want to use a filter that has a slightly larger actual size, so that it does not fall on you when you open the vent. When purchasing a custom-sized air filter, it's important to remember that there is a difference between nominal and actual sizes. Once you determine what exact dimensions work best for you, place an order for your filter size with exact fraction or decimal measurements. Otherwise, you may get a different actual size than you expected.
Unfortunately, there is no one-size-fits-all when it comes to air filters: there are about 20 standard sizes and none have identical measurements. You can proactively cleanse your home's air and surfaces by adding an air purifier in your duct that creates supercharged particles. By using a properly sized filter and changing it regularly, you may experience cleaner indoor air and fewer system problems. The easiest way to identify your air conditioner's filter size is to remove it from its slot and examine its frame. If you use a room air purifier and need to replace its filter, it is important to find an appropriate sized replacement HEPA filter. Placing it backwards may cause it to collapse and cause airflow to circulate around it instead of through it.
It is important to note that there is no need for an airtight seal between its frame and itself. Getting stuck in a large filter where it doesn't belong can damage your HVAC system and not clean your air properly. Each brand may have different actual sizes than their nominal sizes (the sizes on their labels are sometimes rounded). Airflow in wrong directions can create greater resistance and strain your system. The picture of this 12 x 12 x 1 inch air filter has its nominal size, which is usually how air filters are sold by. In fact, if you have to force an air filter in or out, it's probably not the right size; standard sizes are usually half an inch smaller than advertised.
Most large retailers such as Walmart, Target and Home Depot carry air filters with various options and brands available. If in doubt, measure your air filter yourself with a ruler or any other measuring device. By using a properly sized filter and changing it regularly, you can experience cleaner indoor air and fewer system problems.
