Summer is Tough on Air Filters:  Here’s How Commercial Buildings Can Prepare

11–13 minutes to read

When summer hits and temperatures soar, our air conditioning systems work overtime to keep us cool. What many people don’t realize is the significant strain on our buildings’ air filters that this causes. Between increased A/C usage, wildfire smoke, and heightened vehicle traffic, summer air quality takes a hit, leaving your filters to handle more dirt, dust, and pollutants than during any other time of the year.

This article explores how summer affects the performance of your air filters and why upgrading to high-quality filters is a crucial step to protect the health of your building and its occupants.

Increased Airflow from Constant A/C Usage

Global temperatures in the summer of 2024 were the hottest on record in the last 175 years, according to NASA, and 2025 is forecasted to be similar. [1]

Your building’s HVAC system keeps employees and guests safe and comfortable during the summer heat, cycling a continuous flow of air to maintain a cool indoor environment. However, this boost in airflow means your air filters have to work harder than usual due to:

• Constant Air Movement: Even if the outdoor air is relatively clean, running your A/C throughout the day pushes a much higher volume of air through your system. That means filters are exposed to more particles simply due to the increased airflow.
• More Wear and Tear: This constant movement of air doesn’t just bring more dirt; it also reduces the lifespan of your filters as they work to trap an...
