Each unit has a specific size filter that allows it to operate correctly and efficiently. Most air conditioning and HVAC units use standard-size filters, but some require the purchase and installation of a custom-sized air filter. Filters are labeled with three-part dimensions. The first number is its length, the second is its width, and the third is its depth or thickness.
Actual Size Chart The easiest way to identify the size of the AC filter is to remove the existing filter from its slot and examine the filter frame. Typically, 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 check.
In this case, you'll want to round down to the nearest integer to determine the nominal size of your air cleaner. The actual size of your air filter should be 0.25 -0.5 smaller than the slot or frame itself. HVAC unit slots are usually located near the bottom of your air handler. It's best to have a little 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 jam the air filter to install it, try a different brand of oven filter or a custom-sized air filter with a slightly smaller actual size. Central return air grilles are usually found in the hallway, ceiling, or hallway wall of 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 does not fall on you when you open the vent. When purchasing a custom-sized air filter, it's important to remember the difference between the nominal and.
Once you determine the exact dimensions that best fit your needs, place an order for your filter size with the exact fraction or decimal of your preferred measurements. Otherwise, you may get a different actual size than you expected. Let's take a look at the most common oven filter sizes and where to buy oven filters. On the other hand, if the filter is too large, the frame will wrinkle, air flow will be restricted, and longevity will be compromised.
For many people, air filtration is a confusing, rarely talked about topic, where questions are often not asked or answered. Worse, improperly sized air filters can put excessive strain on your HVAC system, damage it, and increase your energy bills. The most common AC filter sizes and oven filter sizes are 16x20x1 air filter, 20x20x1 air filter, 16x25x1 air filter, and 20x25x1 air filter. In fact, if you have to force an air filter in or out, it's the wrong size, so standard sizes are usually half an inch smaller than advertised.
The Lennox filter below shows part number X0583 and Honeywell part numbers, FC100A1029 and FC35A1001, which this filter can replace on the actual filter (see Lennox filter image below for item number and filter size along with compatible filters). If you're looking for a retailer near you that sells custom-sized air filters, you might struggle to get lucky. If you have a system that uses a whole-house filter, you may have a choice from MERV 8 to MERV 16, depending on your HVAC system, if you have a system that has the option of a highly efficient MERV 15 filter, such as Bryan and Carrier, offer germicidal air purifiers. Changing the filter regularly will improve the efficiency of your HVAC system, so it cools, heats or cleans the air with less energy.
When buying an air filter, it's important to keep in mind that the air filtration industry standard is to make filters measure a little smaller than their slot or frame, so they can easily slide into place without bending or breaking. Honeywell, Hunter and Whirlpool have several models of room air purifiers available, so it's important to check compatibility before purchasing a replacement. To the right of the filter, it also includes the actual size of the filter, which are the true measurements, the dimensions of the filter by length, width and depth. Oven filter sizes for standard sizes (also known as standard AC and oven filter sizes) and hard to find are included in the list with actual sizes and MERV options.
However, it has to fit snugly into the air cleaner compartment with a little space around the edges. . .
