The air filter goes into a furnace with the arrow on the filter pointing towards the blower motor or the furnace itself. This indicates the direction of airflow.
Here's a more detailed explanation:
-
Identify the Air Filter Location: The air filter is typically located in a slot or compartment either within the furnace unit itself, or in the return air duct leading to the furnace. Check your furnace's manual if you're unsure.
-
Note the Airflow Direction: Look for an arrow printed on the side of the air filter. This arrow indicates the direction the air should flow through the filter.
-
Install the Filter Correctly: Insert the air filter into the slot, ensuring the arrow points towards the furnace or blower motor. The air is pulled through the filter into the furnace to be heated.
-
Why is the Arrow Important? The filter is designed to catch dust and debris from one direction. Installing it backward can reduce its effectiveness and potentially damage your furnace.
-
Confirmation: After installation, double-check the arrow's direction to ensure it's pointing the right way. Properly installed filter is crucial for optimal furnace performance and air quality.
