An AC filter is a component of the HVAC unit that removes the impurities in the air. This helps improve the room’s air quality and protects the air conditioner components from contaminants. Without an air filter, critical components of the HVAC system could suffer from reduced lifespan. Continue reading to learn more about the importance of AC filters.

Importance of AC Filters 

There are multiple types of air filters available on the market, each made up of a specific mesh or filter media designed to remove contaminants. Generally, the media of an AC filter can trap particulates, including mold, pollen, fiber, debris, dust, pet dander, hair, smoke, and even bacteria. 

AC filters prevent pollutants and contaminants in the air from accumulating on the crucial parts of the AC, such as the blower motor and the evaporator. Running an AC system without an air filter or with a dirty filter can cause debris to gather on the evaporator coils. Dirty evaporator coils would limit the heat transfer, which can cause the AC to freeze, resulting in inadequate cooling or damage. When impurities clog the system, it makes it harder for the unit to draw air, making it less energy efficient and prone to frequent breakdowns. 

Clean AC filters allow the HVAC unit to operate at peak efficiency, preventing energy wastage and unnecessary wear and tear on the system’s components. This helps save money on repairs and utility bills. Installing high-quality AC filters in the unit can also reduce its carbon footprint, making it more environmentally friendly. 

Most importantly, filters maintain good indoor air quality by removing contaminants in the air. AC filters are crucial for your AC units and your health. A lack of air or clogged air filters could promote mold growth in the ductwork, allowing harmful mold spores to circulate in the air and reach your lungs. This can cause health complications. It is also crucial to replace filters regularly.  

Buying an Air Filter 

The type of AC filter you should get depends on your system’s requirements. Each AC unit has a specific filtration requirement that you can confirm from your manufacturer. Typically, most systems require AC filters with a certain MERV rating. 

The Minimum Efficiency Reporting Value rating—which ranges from 1 to 16—is used to measure the effectiveness of the AC filter. Higher MERV ratings indicate that the filter is more efficient in trapping smaller particles. 

However, choosing air filters with higher MERV ratings may not be a good option if your HVAC is not designed for it. This is because these filters are typically denser and can restrict airflow, resulting in the system consuming more energy to draw air. Choosing an air filter with a high MERV rating would not only be expensive, but it could also cost you more in the long run in terms of energy bills. You can also consult an HVAC technician to determine what MERV rating would suit your system before picking out a filter. Click here to learn more about AC filters.
