Air filters are essential for keeping your home clean and healthy. They help to remove dust, dirt, and other particles from the air, ensuring that you and your family can breathe easy. But in order for them to work properly, they must be installed correctly. Most air filters have arrows printed on the sides that indicate the direction of airflow.
This means that the arrows should point away from the supply ducts and towards the blower. If the filter is on the wall, the arrow should face the wall. If you don't have an arrow, you'll want the side with the wire frame to face outward. This means that the side with the wire frame will be on the outside, or the side closest to you, and the side without it will be inside, closer to the unit.
Fortunately, most air filters are designed to not fit properly unless they are inserted correctly. Look for the airflow arrows printed on the side of the air cleaner that indicate in which direction the filter should be inserted. When installing an air filter, it's important not to shake or hit it as this could release particles back into your home. The intake air moves downward, so the filter will be located at the top, in the upper blower compartment.
If an oven filter is installed upside down, it won't properly filter the air which can eventually damage your unit. If you have a ceiling or wall air return that uses a filter, then the arrow should point towards the ceiling or wall. Once you've located where your filters are, you'll need to find out what size you need and determine which MERV rating best suits your needs. With an upflow oven, the filter will be located near the bottom of the unit in the blower compartment next to the cold air return. It's important to routinely monitor your air filters to prevent them from becoming clogged with dirt, dust, or debris and to keep them filtering your home's air. If you install a filter upside down, it can reduce airflow which can lead to poor efficiency and higher energy costs or equipment that works more than it should and breaks down.
We are in the middle of summer and your air conditioner works non-stop, but your house is still damp - this could be a sign that your air filters need replacing.
