Guide to Changing Commercial HVAC Air Filters

How Often to Change Them

Generally, you should change filters in an office space three to four times a year. However, a few factors will influence how often you should change them. If you have construction in the office that kicks up dust, for example, then you should replace them immediately. Likewise, if people bring their dogs into the office, they bring in hair and dander that will clog up the filter so it will require replacement more often. You may also need to change it more frequently during allergy season if you have employees who suffer from seasonal allergies, asthma, or other respiratory issues.

Why It’s Essential

Clean air filters serve a significanthvac purpose for your office. They allow air to move freely through the HVAC system, so it functions more efficiently, thus keeping your office comfortable and your utility bills reasonable. A clean filter does its job in catching contaminants to improve your indoor air quality. This process keeps your employees healthier, your air smelling fresher, and your office cleaner. It will keep dust and other debris out of your electronic equipment such as computers and printers, to prevent them from overheating.
