EPB Offers Recommendations to Improve Customers’ Indoor Air Quality and HVAC Efficiency

Chattanooga, TN (November 16, 2016) – As the smoke from wildfires in the Tennessee Valley continues to degrade air quality, EPB is recommending several ways customers can improve air quality inside their homes while ensuring that HVAC systems continue to perform efficiently.

First, EPB recommends that all customers check and seriously consider replacing their HVAC air filters because smoky conditions will likely degrade filter effectiveness more quickly than normal. In addition to air quality concerns, clogged air filters cause HVAC systems to perform at less than peak energy efficiency. Even if the wildfire smoke is no longer evident, residents should strongly consider changing air filters that may have become clogged during the previous smoky days.

“Keeping doors and windows closed as much as possible is your first defense against fine particulates in smoke,” said EPB manager of Energy Services John Watts. “Additionally, we recommend that people change their air filters more frequently and consider upgrading their HVAC system with more efficient HEPA filters, such as those that contain activated charcoal or other absorbents that can enhance filtration.”

Because higher efficiency air filters may reduce the amount of airflow through an HVAC system, Watts suggested that homeowners consult their HVAC contractor for recommendations on air filters that are compatible with their system.

To further reduce the impact of smoke on health and indoor air quality, people can add an indoor air cleaner that filters at least two or three times the room volume per hour.

“Until the weather pattern changes and the wildfires are extinguished, there’s nothing we can do about the smoke that is blanketing the Chattanooga area,” Watts said. “But we hope our customers will consider a few ways to improve indoor air quality while ensuring that their HVAC systems continue to work as efficiently as possible.”
