As humans, we each breathe over 20 thousand times each day.  Without breathable air, a person can survive only 3 minutes.

The emergence of novel pathogens, an increase of airborne pollutants, growing urban populations, and the rise of international travel requires new technologies to provide clean air and surfaces without exposing people to harmful chemicals.

The Micron Pure™ technology inside of CerroZone™ air purifiers uses ozone and a novel catalyst to inactivate 99.97% of airborne SARS-CoV-2 (the virus that causes COVID-19) on a single-pass through the machine.  Zero ozone is released to the room allowing for continuous use inside occupied spaces.

Americans spend 90% of their time indoors.
Airborne viruses can remain contagious in the air for up to 3 hours.


According to the CDC, there are now multiple SARS-CoV-2 variants circulating globally. These most notably include B.1.1.7 in the United Kingdom (UK), B.1.351 in South Africa, and P.1 in Brazil.

The B.1.1.7 mutated version quickly became the most common version of the coronavirus in the UK, accounting for about 60% of new COVID-19 cases in December of 2020.

Preliminary scientific evidence points to new variants, including B.1.1.7, binding more tightly to human cells. The effectiveness of currently authorized vaccines against these and new coronavirus variants is still being determined.


Micron Pure: 

The Micron Pure™ device is designed to reduce airborne bacteria, viruses, and fungal spores to decrease infection rates from airborne pathogens. For this study, the Micron Pure™ device was challenged using aerosolized MS2 bacteriophage which has been historically used as a surrogate for influenza and is now being considered as a surrogate for coronaviruses such as COVID-19 due to the size similarity to influenza and RNA genome.


The CDC estimates that the influenza virus is responsible for 140,000 to 810,000 hospitalizations and 12,000 to 61,000 deaths annually. This study evaluated the efficacy of the device against aerosolized MS2 bacteriophage as well as various sizes of polystyrene latex microspheres (PSL) in a stainless steel bioaerosol chamber.



The Micron Pure™ device can help to slow the spread of COVID-19.  Reduces airborne contamination from person-to-person, periodically helps to inactivate pathogens left on objects that become airborne from an infected person.  Can Help to Flatten the Curve. Complements measures already in place to lower impact. Enhances the effectiveness of social distancing.  Can be Done Quickly and Effectively. Can help reduce infection while vaccines and medicines are developed and tested.  ​Reduces Contamination.  ​Increased Protection. For high risk and high contamination areas such as hospitals, nursing homes, airports, etc.
