different types of air filters

Owning a home in Hamilton is not a joke. It would be best if you always were on top of your family’s comfort. One key to maintaining this is giving them a quality HVAC system for the cold and hot seasons. But how sure are you that the air is also healthy for them to inhale? That’s where air filters come into the picture. These components of your HVAC partner enable proper filtration of dirt and debris. But what are the types of air filters?


This article will help you assess and choose what type of filter you prefer for your home. We will also discuss the importance of such a part in keeping your HVAC system efficiency.


What is the importance of air filters?


Before we discuss the types of air filters, let us first identify their role. Are they merely an accessory to the system?


Indoor air quality is an essential element of a happy home. Aside from the proper temperature, the air impacts health negatively if it isn’t filtered. As a result, you can get allergies and respiratory problems. But more than that, air filters also block debris and dirt from getting into the internal components. What benefit does that bring? If dirt and debris build inside the system’s internal parts, it can insulate them. When it becomes thick, it hinders the airflow and could lead to overheating. As a result, your HVAC system won’t be able to provide you with adequate cooling or heating. Below, we will discuss the primary air filters you can get for your home.


Reusable Air Filters


As the name suggests, you can reuse reusable air filters. These air filters enable you to clean them when you see fit without disposing of them immediately. They can be pretty costly than those that are disposable. They have a meagre MERV rating, making them more prone to mildew and mould growth. 


Fibreglass Filters


These types of air filters are disposable ones that you can eradicate within a given time. They reinforce a metal grate that has fibreglass as a component. While they aren’t as expensive, they merely do nothing for filtration due to their low MERV rating. 


HEPA Filter


Last but not least, among all the types of air filters are HEPA filters. They have the highest MERV rating that allows thorough protection from airborne particles. They can trap particles as small as 0.3 microns. While they may be a significant investment, they do not fit most home systems immediately. Contractors usually adjust them depending on the modification needed.




Air filters are necessary elements of the HVAC system. They keep the indoor air quality and the internal system components in shape. While some may see them as unimportant parts, it is essential to note that they must also be getting proper maintenance. They are key to preventing furnace failures or air conditioners not working properly. Remember that failure to dispose of, clean, or maintain your filters can impact the overall well-being of your HVAC system. If left ignored, they could trigger costly repairs in the long run.
