One thing that has been discussed extensively, aside from face masks, during the coronavirus pandemic is whether or not air filtration indoors plays a big role.
According to the United States Environmental Protection Agency says on their website about air cleaners, HVAC filters, and COVID-19: "Air cleaners and HVAC filters are designed to filter pollutants or contaminants out of the air that passes thru them. Air cleaning and filtration can help reduce airborne contaminants, including particles containing viruses. Portable air cleaners (also known as air purifiers) may be particularly helpful when additional ventilation with outdoor air is not possible without compromising indoor comfort (temperature or humidity), or when outdoor air pollution is high."
Lydall is a global manufacturer of specialty engineered products and it's a supplier of the melt-blown filter for N95 masks and it makes filters.
Now, before we go any further, what is MERV?
MERV stands for Minimum Efficient Reporting Value, which--according to the CDC--helps to show "filter’s effectiveness to capture solid particulate as opposed to liquid aerosols. The 1999 standard rates particle-size efficiency results as a MERV between 1 and 20. A higher MERV indicates a more efficient filter."
Now, back to Lydall, which makes MERV-13 filters. CEO Sara Greenstein joined TheStreet to discuss MERV-13 filters and their importance.
