A new study reaffirms the role flooring has in improving indoor air quality (IAQ).

Research by The Carpet and Rug Institute (CRI) found that carpet flooring captures more particulate matter (PM) than other flooring types. With its fibers acting as an air filter, PM decay rates were greater in carpeting versus hard surface flooring. Moreover, contaminants can become further embedded into carpeting with increased foot traffic, reducing airborne recontamination risks.

According to the American Lung Association’s annual air report, 44 percent of Americans live in areas with compromised air quality. Although traffic and climate change effects remain the primary air pollutants, an increase in data center facilities also contributes to contamination. These external factors impact IAQ, making proper filtration and carpet care essential for commercial cleaning operations.

IAQ is a public health priority, making correct carpet cleaning critical for occupant well-being. The CRI recommends the implementation of vacuums with a high-efficiency particulate air (HEPA) filter. Frontline teams should be trained on vacuum frequency and technique, referring to the manufacturer's guidance as needed. If carpet is cleaned through encapsulation and/or steam cleaning, it is important to ensure the carpet is properly dried, or it can produce mold and mildew.
