merv-13 upgrade takes the scare out of the air for nyc schools

MERV-13 filters have been shown to reduce students risk of transmission and protect students from contracting SARS-CoV-2 virus because the filter is more efficient at capturing the virus than more used window air conditioning filters.  Images courtesy of Eneref Institute.
Only few viruses have ever become endemic, among them are ebola, flu, swine flu, MERS, Rift Valley, SARS, West Nile virus, Zika virus, and COVID-19. Influenza is also respiratory infection and causes more hospitalizations among children than any other disease.
Early in COVID-19, Friedrich Air Conditioning Co recognized its standard window and through-the-wall air conditioner lines were already built with the necessary headroom to expand filtration from MERV-6 to MERV-13 filter...
We talk about the cleaning and all those things with parents, and I think sometimes we do not go into the air conditioning and those types of details with them, said Lavonne Gaston, parent coordinator, Boys, and Girls High School..
While HVAC filtration system reduces exposure to airborne pathogens, the more robust filters also increase resistance to airflow inside the air conditioners.
Four months later, December 2021, New York State Education Department sent out its own directive from Office of Facilities Planning, recommending high-efficiency MERV-13 air filters as proven and method for removing pathogens and other contaminants with HVAC system...
Friedrich employs numerous technologies to protect the coils from restrictive airflow, including forward-curved blowers, the performance of the compressor and heat exchangers, the overall design, and the shape of the filter to fit for optimal performance..

According to Centers for Disease Control and Prevention, MERV-13 filters are significantly more efficient at capturing particles of concern.
