Can You Put an Air Filter in Wrong? - A Guide to Proper Installation

Installing an air filter in the wrong direction can be a costly mistake. Not only will it waste energy, but it can also damage your air conditioner or heating system. Furthermore, it can lead to a decline in indoor air quality. To avoid these issues, it's important to understand how to properly install an air filter.

When installing an air filter, it's important to pay attention to the arrows printed on the sides of the filter. These arrows indicate the direction in which the filter should be installed. If you place the filter backwards, air will struggle to flow through the filter material and your air handler will have to work overtime to compensate for the loss of airflow. In addition, air will be able to bypass the filter completely due to an imperfect seal created by folding the filter.

This will cause dirt and debris to build up on the fan, slowing down airflow and degrading performance. It can also decrease air quality and create a big mess that you'll have to pay to repair or clean later. All air filters have one side that is more porous than the other. The porous side allows the filter to trap particles in the air without restricting air flow through the air conditioner.

If you place the filter backwards, air will have more difficulty entering the air conditioner and the unit will be forced to work harder to compensate for the lack of air flow. The only solution if you have an air filter that is too small is to find one that fits properly. A small filter leaves gaps around the ventilation grille, allowing harmful particles in the air to pass through the air conditioner. All air filters have specific performance ratings, indicating how well they can remove large and small particles from the air.

It's important to replace your air filter regularly as they become clogged over time and lose efficiency. If you install an old or clogged filter, your HVAC system will have to work harder and cost you additional money. To ensure that your HVAC system works efficiently and that you breathe quality air, it's important to change your air filter all year round. Pay attention to arrows printed on filters when installing them and make sure they are replaced regularly.
