HEPA filter installations in HVAC Units

The quality of air within your workplace is challenged every day by the materials, processes, and people that pass through it. Production and manufacturing processes generate a substantial number of particulates that can linger for hours and days in the air. Add to that newly arrived stock and materials along with employees and customers in your workspace and the probability of the spread of germs and viruses grows exponentially.

For the best level of protection against these airborne threats, an HEPA filtration system that works in concert with your HVAC is essential.


HEPA, which stands for High-Efficiency Particulate Air, is an extremely effective method of filtering, cleaning, and purifying the air inside your workspace. High quality HEPA filters capture and remove microorganisms, airborne particles, and other pollutants. The HEPA filters we recommend are almost 100% effective at filtering out airborne contaminants of 0.3 microns or larger, including:

As well as, other tiny contaminants. Some types of HEPA filters that have activated charcoal or carbon inserts can also filter out odors and fumes.

Particles and contaminants are removed by HEPA filtration by:


HEPA Filter Diagram

1. Interception

Particles that are close to the filter, adhere to it.

2. Impaction

Particles are moved by the airflow, causing them to come into physical contact with the filter material and stick to it.

3. Diffusion

Very small particles (of 0.1 micron or smaller) collide with other tiny particles such as air molecules, causing them to be deflected into the filter and trapped by impaction or interception.

Why not regular HVAC filters?

A HEPA filtration system provides a level of indoor air filtration that traditional HVAC filters cannot. HVAC filters are rated according to a Minimum Efficiency Reporting Value (MERV) that range from a fairly ineffective 1 to a relatively high filtration level of 16. HEPA filters, by contrast, clean air at MERC levels of 17 to 20.

HEPA filters are especially ideal for environments in which air quality is critical, such as:

What can HEPA filters remove?

Airborne Contaminants

A HVAC system with HEPA filters removes biological and inorganic material that enters the facility through doors, windows, and its own intake. This includes matter produced by activities and materials and within your workplace including:

HEPA filters are especially ideal for environments in which air quality is critical, such as:


A Reminder

Because HEPA filters are dense and thick, they can adversely affect airflow in your HVAC system. We work with you to ensure your heating and cooling systems can tolerate the stresses caused by HEPA filters before installing them. HEPA filters must be checked and changed on a regular basis to ensure the air cleaning possible is maintained.

Depending on the type HEPA filter installed, replacement should be from between 3 months to two years. It is essential they are checked on a regular basis to ensure high quality airflow.
