Commercial Air Filter Installation and Replacement

To maintain healthy air quality, air filters for commercial buildings should be replaced quarterly, although this frequency may differ depending on the type of environment. In cleaner, office-like buildings, this schedule may be closer to 3–4 times a year, whereas, in more sensitive or polluted environments such as hospitals or factories, replacement may be needed monthly (or even weekly). HVAC sensors can help determine this schedule.

To determine the correct size air filter, you can look at your existing filter for measurements—typically listed on the outer edge. There should be three measurements: length, width, and thickness. However, if you plan to install or upgrade a filter, the thickness measurement may change. The best way to accurately size your filter and avoid HVAC damage is with professional services like Aire Serv.

To produce cleaner air and help remove harmful pollutants in your commercial environment, it’s recommended that you use filters with a higher MERV rating. For most commercial spaces, a rating of 13 is ideal. Ratings of 16–20 are typically found in medical spaces. However, there are also various types of filters, including fiberglass, washable, HEPA, UV, and more. An HVAC specialist can best determine the right fit for your building.

Standalone commercial air filters or HVAC air filters should be serviced regularly to avoid the buildup of harmful airborne materials and potential HVAC unit repairs. Professional service helps to prevent the buildup of harmful airborne particles and helps to identify potential damage to your unit before it’s too late.

Here are a few signs you may require more frequent air filter replacement:

• Increased allergens
• Higher heating and cooling bills
• Debris buildup around the filter, unit, or building
• Stale or musty smells
• Decreased HVAC unit efficiency

It's also important to frequently reevaluate your replacement schedule as you obtain new workers, tenants, or changing environmental conditions. It's possible that pollutants change or that those routinely visiting your building have more severe allergies. If so, filters may need to be upgraded or more frequently changed.
