Why Is It Important To Have Quality Air Filters?

Having good air quality filtration is not only important for eliminating airborne contaminants and improving your IAQ, but it can also help you save money on repairs and energy costs. Good quality air filtration that reduces contaminants can also improve the energy efficiency and life of your HVAC system(s). 

Because many air filter types exist, determining which one is best for the needs of your facility or building can be challenging. There are many types and sizes of air filters on the market. It is important to ensure that you’re using the right kind of filter for your HVAC system, otherwise you risk health concerns and costly repairs. Air filters that are too big may allow allergens and contaminants into your air. Likewise, if a filter is woven too tightly, it can restrict airflow, use more energy, and even break your system.  

HEPA Filter


Understanding what the HEPA and MERV acronyms mean will make you more knowledgeable on the conditions and specifics of how your facility is capable of creating good indoor air quality conditions that allow employees and visitors to breathe healthy air.

HEPA stands for high efficiency particulate air and is a type of pleated mechanical filter commonly used in hospital and healthcare facilities. Most HEPA filters can eliminate up 99.7% of airborne particles down to 0.3 microns.  HEPA filters have recently seen usage in combatting the spread of Coronavirus, as SARS-CoV-2 droplets are only 0.125 µm. 

MERV stands for minimum efficiency reporting values, which are numbers used to report a filter’s ability to capture large particles. The higher the rating, the better the filter is at trapping certain particles. Many find the MERV rating helpful when comparing the performance across different filters. MERV ratings are derived from a testing method developed by ASHRAE. MERV values range from 1 to 16. Based on the current metrics surrounding MERV ratings and the particles they are capable of catching, filters with a rating of MERV-13 or higher are best in fighting SARS-CoV-2 and coronavirus.

Polarized Filtration Systems

Additionally, polarized filtration systems, such as the Purity Low Profile filters offered by EcoGroup USA, use a polarized charge to attract particles of all sizes (down to 0.1 microns). Once these small particles are clumped together, they are easily captured by the replaceable filter media without restricting airflow. Purity Low Profile filters also reduce odor-causing VOCs by 30% per pass, come with a lifetime system warranty, and only need to be changed every 4 to 6 months on average.

Commercial businesses such as office buildings and hotels can especially benefit from having good air filters because of their ability to protect furniture and décor. By removing airborne dust, you can avoid staining of surfaces and having to wash items such as pillows and curtains, which can increase their lifespan.

Creating Clean Air

Under the right conditions, air cleaners may help reduce the health effects of some of the invisible particles in the air. However, air cleaners cannot remove particles that have landed on surfaces unless they re-enter the atmosphere by being disturbed. Technology like UV-C lamps are capable of preserving cleanliness of these surfaces where particles have settled. Air cleaners without special media are not effective at removing or protect humans from gaseous pollutants, such as radon.  

Combining quality air filtration with disinfecting technologies like UVGI (ultraviolet germicidal irradiation) can have massive benefits for the air quality of your facility. UV-C lamps kill buildups of mold, biofilms and fungi that form in humid conditions that sometimes form in the filtration systems found in HVAC infrastructure. By combining multiple IAQ technologies that work alongside each other to create the safest air possible, your facility can remain a safe place for employees to work – reducing absenteeism and promoting productivity.
