The Importance of HVAC Filtration

You’re probably aware on some level that air filters are a necessary part of your heating and cooling systems. However, you might be surprised to learn just how critical they are. Air filters exist to prevent pollutants from moving through your HVAC systems. These pollutants include, but aren’t limited to, dirt, dust, pollen, pet dander, and mold spores. They can come from the outdoors when they’re carried in on your clothes, or they can be created and dispersed by general, day-to-day living. 


No matter what time of year it is, your HVAC system is working hard behind the scenes to keep you comfortable. More frequently than not, a day will come when you need to change / clean your filters.

Types Of Filters

HVAC filters aren’t universal. You’ll need to buy the right ones if you plan on replacing them.

The first thing to consider is size. While there are standard sizes for furnace and air conditioner filters, they run on a scale, so you’ll need to check and see which ones are used by your own units.


Air filters come in several types, including fiberglass, pleated, washable, and electrostatic air cleaners.​ Each type has its own benefits, and some might not be compatible with every HVAC unit.

Fiberglass HVAC Filters

The biggest advantage of using fiberglass air filters is that they are inexpensive when compared to more advanced filters like pleated filters or electrostatic air cleaners. 

Pleated HVAC Filters

The main advantage of using pleated filters over fiberglass filters is that they have higher MERV ratings, allowing them to remove more particles, and they also last longer.

Washable HVAC Filters

Although washable filters don't have any advantage over the others as far as filtration, they do reduce waste, save money in the long term, and allow you to avoid stocking up on filters.

Electrostatic Air Cleaners
Electrostatic air cleaners are better at filtering airborne particles than regular disposable air filters. These filters are effective at filtering most harmful contaminants from the air without making your HVAC system work harder to push air through a thick filter. These filtration systems are also reusable.

MERV Ratings

MERV stands for Minimum Efficiency Reporting Value, a rating system created by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). MERV ratings signify an air filter’s effectiveness at decreasing airborne particles and pollutants, determined by the smallest particle it’s capable of trapping (measured in microns). As filters become better at improving indoor air quality, their MERV rating goes up, ranging from 1 to 20.

What Happens If You Don't Change/Clean Your Filter


High Energy Costs

A dirty air filter stifles air circulation, forcing your HVAC system to work overtime to heat or cool your home. This leads to higher electricity bills and can shorten the lifespan of your HVAC unit.

Inconsistent Air Temperature

Because the HVAC system is struggling to blow air, certain areas of your home may be hotter or cooler than you'd like. A dirty air filter can even interfere with the temperature sensors that signal your HVAC system to start or stop. The result is discomfort, inefficient operation, and repair costs due to high strain on the fan motor.

High Risk of System Failure.

A worn out fan motor combined with difficulty in moving air inevitably leads to overheating or freezing up. The air that would move freely through a clean air filter becomes trapped behind a dirty one, placing high energy demand on your HVAC system.

Poor Air Quality

A dirty air filter traps not just air, but moisture. Under humid conditions, this promotes the growth of bacteria and mold, which further clog up the filter. Even worse, these microbes can spread into the HVAC system and into the air in your home, causing allergic reactions and other health issues. Left unchecked, this can cause long-term health problems, especially for young children and the elderly.

Dirty Air Ducts

A buildup of pollutants in your air ducts further reduces the efficiency of your HVAC system and increases pollutants in the air throughout your home. Changing your air filter is much quicker and easier than dealing with the fallout from polluted ducts.
