They both agree that proper medical-grade HEPA filtration is an excellent solution to capture viruses, bacteria and other contaminates.
As our team traveled back from the Realcomm conference outside of Denver, on a Delta Airlines flight, they were reminded the carrier uses medical-grade air filtration technology to keep their customers and employees safe.
Breathe easier knowing your air is clean on all Delta flights. Delta's air filtration system recirculates the air through industrial-grade HEPA filters. The air is cleaned every two minutes through a HEPA filtration system.
According to ASHRAE: “Ventilation and filtration provided by heating, ventilating, and air-conditioning systems can reduce the airborne concentration of SARS-CoV-2 and thus the risk of transmission through the air.”
Minimum Efficiency Reporting Values (MERV) ratings are a measure of a filter’s ability to capture particles 0.3 to 1.0 microns. MERV values are not standard and will vary from one brand to the next, so it’s important to check brand, system and compatibility.
High Efficiency Particulate Air (HEPA) filters are a type of mechanical air filter and can theoretically remove at least 99.99% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns. The diameter specification of 0.3 microns responds to the most penetrating particle size (MPPS).
