When people became aware that transmission of SARS-CoV-2 was primarily through the air, reducing airborne exposure in buildings immediately became a high priority. 

Standard 241 was developed to reduce the risk of infectious aerosol transmission in buildings.

Boys and Girls High School in Brooklyn, one of 1,859 New York City public schools, was an early adopter of MERV-13 filtration for its numerous window air conditioning units.

The lingering aftermath of COVID-19 represents the historic calling of ‘sink or swim’ through the reengineering of air quality and filtration technologies as we envision sustainable ways of living indoors.

Recognizing the role of nature in airborne disease transmission is a major step in the path to comprehend the past and address the future.

The study was conducted over 30 months with more than 100,000 patient-days. Following implementation of advanced air purification technology, HAIs at St. Mary’s went from an average of 11.9/1,000 patient-days to an average of 6.6/1000 patient-days — a 45% reduction.

The idea that we can’t afford the cost of infection control is no longer valid. There’s too much at stake.

This study presents a comparison of computational fluid dynamics (CFD) models of different room configurations with different airflow rates and patterns, in order to uncover the optimized HVAC air distribution design that can effectively control the spread of COVID-19 and similar diseases.
