NuWave said that an independent study conducted by the University of Minnesota Department of Mechanical Engineering has found that the company’s OxyPure Air Purifier reduces porcine respiratory coronavirus concentration in the air.
While recirculating air purifier units have been proven to remove dust, allergens, and pet dander from indoor spaces, NuWave sought to test OxyPure’s effectiveness against viruses, specifically porcine respiratory coronavirus, a known proxy for other coronaviruses (including SARS-CoV-2, the virus that causes COVID-19).
“The University of Minnesota has a long history of developing techniques to measure and monitor particle concentrations in the air, such as aerosols in the ambient air in indoor environments. UMN focuses their efforts on understanding the role particles play in influencing atmospheric chemistry, air quality, and developing techniques to remove pollutant particles from the air we breathe, including indoor environments,” said James Moon, general manager, NuWave.
Chris Hogan, professor of mechanical engineering at the University of Minnesota, said, “The research focus of my lab group is the testing of control technology to remove pollutant particles specifically including infectious particles with viable viruses in them from the air that we breathe.”
Hogan added, “On the OxyPure unit, we got an overall removal efficiency of 98% in our testing. The OxypPure unit can get a removal efficiency of 98% because it uses multiple control technologies in it. First, the airflow passes through an electrostatic precipitator, a device designed to first ionize particles, so that they’ll move in an electric field. Following the electrostatic precipitator, a high-efficiency particulate air filter is integrated with an activated carbon filter for particle removal; these two technologies together in the OxyPure unit are extremely efficient in combination and removing particles.”
The test, according to the company, proved that a single pass removed 98.24% of the PRCV concentration at a volumetric flow rate of 70 cubic feet per minute CFM (fan speed level at 1). Chris Hogan, and his team, were able to calculate that, in just under six hours, this would yield a 99.999% reduction of the virus in a 1,200 square foot room at a volumetric flow rate of 350 cubic feet per minute CFM (fan speed level at 6).
The OxyPure air purifier’s advanced filter system is designed to capture microscopic airborne particles as small as 0.09 microns and features a five-stage filter system. The air cleaner is available for $699 on NuWave’s website, Amazon and retailers nationwide.
