Installing a furnace air filter is not a difficult task, but it is important to make sure it is done correctly. The filter should always be positioned with the arrow pointing towards the oven, as this indicates the direction of airflow. If the filter does not have an arrow, the thinner or lighter side should face the air handler, oven, or blower compartment. It is essential to keep your oven filter clean and in the right direction in order to ensure proper airflow throughout your home.
A high-rated oven filter can reduce airflow too much, while a low-efficiency filter won't filter dust effectively. Therefore, it is important to calculate the MERV size and rating before changing your oven filter. When installing the new filter, make sure that the arrow is pointing towards the oven. This will ensure that the spent air is sucked in and flows through the air cleaner before being blown back into your home.
Setting the oven filter upside down could cause permanent damage to your HVAC system. Understanding how to use your oven filter correctly will help you reduce energy costs and keep your HVAC system clean. Replacing the air filter is not difficult, but it is important to make sure it is done correctly.
