Your commercial HVAC unit uses filters to clean the air that travels through your office’s heating and cooling system. An air filter will not only provide clean air for your employees, but it also protects your HVAC equipment from dust and particles to prevent potential issues and breakdowns.

Because of this, it’s crucial to find the one that’s right for you. Find the appropriate size, design and level of effectiveness in removing particulate matter that’s needed to improve your Indoor Air Quality, worker health, and productivity.

Which MERV is right for you?

HVAC system air filters are rated based on a Minimum Efficiency Rating Value (MERV) between 1 and 20. The higher the MERV number is, the more dust and other particulate matter it is able to remove from your business’s air.

Filters with a MERV 1-4 filter the least amount from the air, but they are able to keep larger contaminants out of the system. Commercial facilities generally benefit from MERV 8-10 to keep air clean and filtered for employees.

High-Efficiency Particulate Air

High-Efficiency Particulate Air (HEPA) filtration has the highest filtration ability with ranges from 17-20 MERV. These filters are reserved for facilities such as hospitals that need specialized HVAC equipment to prevent the spread of bacteria and diseases, as they can remove at least 99.97% of contaminants up to 0.3 microns in size.

Contaminants of concern should be carefully evaluated to determine the level of filtration efficiency required for the contaminant size. The size of contaminants is measured in micrometers (microns). For facilities that need to filter even the smallest of contaminants, a HEPA air filter may be the best choice.

The Importance of Your HVAC Technician

With increased heating and air conditioning filtration efficiency comes a higher resistance to airflow and an increased need for proper sizing and design of equipment. You’ll need an experienced commercial HVAC contractor to ensure your industrial HVAC equipment is working at optimal levels for your company. If the technician fails to install filter seals and gaskets properly, air can find its way around the filter, rather than passing through it.

“A 10 millimeter gap (less than ¼ inch) between filters can lower a filter’s MERV rating by at least two levels, thereby taking a high efficiency filter and moving it to a medium efficiency filter.” – National Air Filtration Association
