Which way does air filter go in?
To properly insert a new filter, look for the arrow! The arrow on your filter should always face the unit and away from the return air duct that carries the air that will be heated or cooled. HVAC systems push the cool or warm air out and pull spent air in, recirculating the air throughout your home.
What happens if air filter is backwards?
If you put your filter in backwards, the usually collective end of the device will not face the air supply. Your filter will aid in keeping debris in the air. This results in a clogged filter and inaccurately cleaned air getting into your lungs. This is what happens when the air filter is backwards.
Is there a wrong way to put in an air filter?
By installing your filter backwards, air will have a harder time flowing through the filter and your air handler will have to work harder to make up for the loss of airflow. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.
Can you put an air filter in wrong?
If you install your filter in the wrong direction, air will have a hard time flowing through the filter’s material and your air handler will have to work overtime to make up for the loss of airflow. This is not only a waste of energy, but it can also possibly damage your air conditioner or heating system.
Does the arrow go up or down on the air filter?
Position the airflow arrow so that it points in the direction the air is flowing. In addition to clean air, filters also protect your HVAC system from debris and dirt buildup. The airflow arrow should point towards the furnace/blower motor to collect harmful particles before it reaches the furnace’s equipment.

Why is my house so dusty?

Why does my house get dusty in one day?
