Improving Indoor Air Quality with Air Filters

Learn more about how Air Filters can make a difference in your home and improve the quality of the air you breathe in daily.

To make sure airflow is always adequate, we strongly urge residents to check their air filters frequently and replace them when necessary. For those wanting to improve air quality, upgrading your air filter to a more effective one is a great idea. Not all air filters are created as equally and effective. Those run-of-the-mill washable pleated fiberglass air filters barely improve the performance of the HVAC system, and do nothing to improve the air quality in the home. To promote air quality, you want the filters with higher MERV ratings. Similarly, upgrading to a thicker air filter, like an air filter that’s four-inches rather than the one-inch filter that’s most commonly used, will help a lot.

Understanding MERV Ratings

MERV, which is short for Minimum Efficiency Reporting Value, is an industry-standardized rating system for air filters that rates filters on a scale of 1 to 16, with 16 being the highest-rated air filter. Residential HVAC systems can use filters rated as high as 13 on the MERV scale.

Change Your Air Filters!

Air filters should be changed regularly in your home to keep your system running smoothly and to maintain optimal air quality. It can be easy to forget this small HVAC maintenance aspect, especially if you don’t know how often to change it. The frequency at which your air filter should be changed depends on a variety of factors, such as home size, pets, and air quality. For best results, consult with your HVAC technician – but generally every 2 to 3 months.

Health Effects of Poor Indoor Air Quality

By reducing or eradicating airborne contaminants floating around we might not be aware of, we decrease associated health problems. However, the problem with indoor air pollution, what makes it insidious, is that a great deal of the health problems aren’t evident immediately after exposure. Because some forms of indoor air pollution can linger for years and cause severe health problems down the road, it would behoove a homeowner not to investigate, or to educate themselves, and to find out what’s floating around in the air in their home.

Short-Term Effects

  • Headaches, irritation of the eyes, nose, and throat, dizziness, fatigue, tiredness
  • Itchy skin
  • Asthma irritation 

Long-Term Effects

  • Respiratory diseases
  • Trouble breathing
  • Heart disease
  • Cancer

Types of Air Filters

There are many types of air filters on the market, but which one is best for your specific HVAC system?


HEPA filters, or high-efficiency particulate air filters, have a uniquely designed filtration technology that is able to trap up to 99.97% of all particulates in the air in your home. Commonly used in hospitals and laboratories and other medical facilities, HEPA filters are not intended to be used on a lot of residential HVAC equipment, so be sure to check with your technician before trying to use one on your system.


Carbon filters are designed specifically to remove odors. Odors are often tiny gas particles that cannot be captured by normal air filters, or even highly efficient filters like electrostatic and HEPA filters. The carbon is treated with oxygen in a process that opens up millions of very tiny, highly absorbent pores that capture certain particles. Carbon filters remove smoke, gases, vapors, and even certain chemicals. They are perfect for people who have a problem with unpleasant odors.


A pre-filter goes before a system’s main air filter. Pre-filters capture large particulates that would usually clog the first filter a lot easier. They are great for keeping the main filter-free and able to efficiently trap smaller, more harmful microscopic allergens. This provides much longer-lasting filtration and improved filter performance. For the best air filtration results, pre-filters are always recommended.


This advanced air filter is made with charged material that acts like a magnet to draw oppositely charged air particles. This magnetic effect enables the filter to seize far more particles than the average filter, including microscopic pollutants like allergens, bacteria, and smoke. Pleated filters have a larger dust-holding capacity. This makes the filter longer-lasting and far more efficient. Electrostatic filters will still need to be changed regularly because the more pollutants they trap, the less of a charge they carry.
