You simply need the filter size that fits your air return. You can usually find that size on the side of the air cleaner you already have in use. This size will be the nominal size, which means that it is rounded off its actual size. What type of filter do you have? Start by turning off the oven.
Remove the existing oven filter, which will be inside the oven or inside the return air vent. Look for an arrow on the filter that indicates the direction of the air flow. Using a permanent marker, draw the direction of the air flow on the outside of the oven, so you always know the correct way to install the filter. Next, consider the size of the oven filter, which will be printed on the cardboard frame.
Hello, my heating unit is FG7SA-045C-23A. Step 1: Measure the length and width (L x W). If the filter is not square, the smallest measurement goes first). When in doubt, you can always measure your air filter with a ruler or any other measuring device.
To ensure that the next filter you purchase is the correct size for your system, you should measure the inside dimensions of the air cleaner inlet. If your oven has an air filter in the return vent, changing the filter is easy, as it can be done from inside your home. If you have pets, heavy carpets, and have a construction area next to it, the air quality will be poor. Pleated filters are best for moderate to high MERV values and capture smaller particles and allergens.
Basically, when you take measurements of an air filter, you just need to round the nearest inch to find the dimensions of the filter you need to buy. After all, the filter is what separates you and your sensitive central forced air equipment from the destructive particles in your home air. When you change oven filters, the first thing you want to do is to know what size oven filter you have. 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 doesn't fall on you when you open the vent.
For example, Home Depot mainly sells Honeywell brand air filters, while ACE Hardware mainly carries Filtrete. Most major retailers, such as Walmart, Target, and Home Depot, offer air cleaners, albeit with a different variety of options and brands to choose from. Therefore, the filter slot will be slightly smaller than the size of the air filter you need to buy. This is important because the concentration of air pollutants inside your home can be two to five times higher than the concentrations normally found outdoors.
These filters are only recommended for those most vulnerable to disease, as they capture virtually all particles, even attached viruses, which measure 0.3 microns or larger.
