Are you looking for the right size air filter for your home? It can be a daunting task, especially if you don't know where to start. Fortunately, there are a few simple steps you can take to make sure you get the right size filter for your home. 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.
To find the size of the pleated filters used in your home, you don't need to look any further than existing filters. On the outer frame, you will see at least one numbers game. If you see two sets of numbers, the filter size needed to order replacements is the nominal size, not the actual size. You can ignore the actual size printed on the filter for this task, since the nominal size is the number needed to order new filters. The first (and easiest) way to find out the filter size of your oven is to check the size of your previous air filter.
If your old air filter does not have the measurements printed on its side, you can measure it yourself. Step 1: Measure the length and width (L x W). If the filter is not a square, the smallest measurement comes first). If the filter is too large, it won't fit into the filter slot and you won't be able to put the cover back on.
Look inside the section of the oven where the air filter should go, there should be a 1″ filter track or opening where the air filter slides through. Timely replacement of your oven filter is much easier when you know what size air filter you need. Proper maintenance will maintain good air quality in your home, increase the lifespan of your system, and consume less energy, reducing your bills. This is particularly important to remember if you live in areas that see a lot of air pollution from things like smog. As a pleated filter becomes loaded with contaminants, it can eventually decrease air flow to a critically low amount. Washable electrostatic filters are metal frame filters that are designed to be washed and reused rather than replaced.
Therefore, no matter what situation you are in, you will be able to calculate the filter size of your oven. However, according to Energy Star, filters must be changed every month during peak summer and winter months, when the HVAC system is operating at full capacity.
