Chesterfield, Missouri, July 21, 2022. Micron Pure is pleased to announce that its patented
ozone technology recently received Federal Drug Administration (FDA) 510(k) Class II
clearance for the CerroZone Mobile device as a recirculating air cleaner for eliminating airborne
Viruses and Bacteria.

Micron Pure has licensed the technology to Marmon Holdings, a Berkshire Hathaway Company,
who will be selling Air Purifying Devices under the brand name of CerroZone

Since the start of the COVID-19 pandemic, Micron Pure has been working on solutions to
combat the spread of airborne disease. The past two years have been devoted to tireless
innovation and third-party lab testing conducted at MRIGlobal, Lab for Infectious Disease
Research (LIDR) at the University of Missouri, ARE Labs, and others. Results showed that
Micron Pure’s ozone technology destroyed in a single-pass of 1.2 seconds 99.998% of actual
SARS-CoV-2 (Delta variant) and over 99.97% of gram-positive bacteria (MRSE).

“We continue to develop additional product lines focused on promoting and protecting human
health and the environment,” said John Bergida, President of Micron Pure. “As part of that
ongoing effort, Micron Pure is re-investing in the St. Louis area by expanding into a 25,000+
square foot R&D facility located in Fenton, MO creating manufacturing and engineering jobs.”

design, and ethically solve formidable problems” related to air purification and surface
