(NAPSI)—Here’s an idea that can feel like a breath of fresh air: The U.S. Environmental Protection Agency (EPA) has discovered a key strategy for improving indoor air quality (IAQ). In a newly released fact sheet, the EPA outlines three core best practices: source control, improved ventilation, and effective filtration and air cleaning.

As IAQ takes center stage in conversations about public health and building safety, the National Air Duct Cleaners Association (NADCA) helps move the industry forward with science-based standards and field-tested methods. Its members don’t just follow best practices—they help define them.

Here’s how the association supports each of the EPA’s key strategies:

Ìý
Source Control—NADCA has long led the charge in advocating for source removal cleaning, the most effective method for eliminating contaminants inside HVAC systems. This approach is central to NADCA Standards, which provide detailed protocols for identifying and removing dust, debris, and microbial growth.Ìý

Improved Ventilation—Clean duct-work lets HVAC systems operate more efficiently, so fresh air can circulate freely throughout your house or office building. NADCA-certified professionals are trained to evaluate system airflow, identify restrictions, and offer solutions that improve ventilation and air exchange, key components of a healthier indoor space.

Ìý
Filtration and Air Cleaning—When HVAC systems are dirty, even the best filters can’t perform effectively. Cleaning the system helps restore filtration efficiency, reduces the chance of particle bypass, and supports overall performance. NADCA’s training addresses this dynamic directly, equipping professionals with the knowledge to make filtration more effective through system hygiene.

NADCA’s credibility is rooted in science, continuous education, and real-world application. NADCA Standards are maintained by a committee of subject matter experts and grounded in research, collaboration with affiliated standard-writing organizations, and decades of field experience. NADCA also invests in studies that examine the effect of clean HVAC systems on airflow, energy efficiency, and occupant health.
