COVID-19 & SecureAire

SecureAire’s Effectiveness on Airborne Pathogens Including COVID-19

As you can imagine, we have been inundated with questions about SecureAire’s effectiveness on airborne pathogens, with specific mention of COVID-19, otherwise known as the Coronavirus.

This letter will summarize our research and experience with SecureAire® technology and its effectiveness at capturing and destroying airborne pathogens in any occupied space.

What the Center for Disease Control says about how the Coronavirus is spread.

The virus is thought to spread mainly from person-to-person.

  • Between people who are in close contact with one another (within about 6 feet).
  • Through respiratory droplets produced when an infected person coughs or sneezes.

These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.

It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but the principle mode of transmission is by way of airborne droplets.

How easily a virus spreads from person-to-person can vary. Some viruses are highly contagious (spread easily), like measles, while other viruses do not spread as easily. Another factor is whether the spread is sustained, spreading continually without stopping.

The virus that causes COVID-19 seems to be spreading easily and sustainably in the community (“community spread”) in some affected geographic areas.

What is the difference between a virus and bacterium?

Viruses are not living thingsViruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, such as human cells, viruses would not be able to multiply.

Bacteria are a major group of living organisms. Most are microscopic and unicellular, with a relatively simple cell structure lacking a cell nucleus, and organelles such as mitochondria and chloroplasts. Bacteria are the most abundant of all living organisms.

Viruses are smaller than bacteria and can’t survive without a living host. A virus attaches itself to cells and usually reprograms the cells to reproduce itself. Also, unlike bacteria, most viruses do cause disease. Common examples of virus-caused diseases include the common cold, AIDS, herpes, and chickenpox.

Why normal household filters won’t remove and destroy pathogens like viruses and bacteria.

There are two reasons why normal household filters are not effective at removing and/or destroying airborne viruses or bacteria:

  1. Viruses, bacteria and the smallest, health-threatening airborne particulates are so tiny, with so little mass, that they essentially remain permanently suspended in the air unless something makes them larger and heavier enough to be caught up in the airstream and brought back to a filtration device.
  2. Normal air filtration devices can’t trap small particles like viruses and bacteria, neither do they have a mechanism for destroying living organisms like bacteria.

How SecureAire’s technology removes and destroys airborne pathogens.

First, SecureAire® uses ACTIVE™ Particle Control to cause all airborne particles, including viruses and bacteria, to attract and bind to each other, making them larger and heavier so they get caught up in the normal household airstream and are then returned to our air purification cartridge.

Second, once captured in the air purification cartridge, all particles are collected on millions of individual fibers and held there with strong ionic bonds, where they will remain until the cartridge is removed and thrown away.

Those pathogens that are captured are subjected to a high-intensity energy field that will cause cellular stress and destroy any living organisms, including the toughest bacteria that are found in hospitals and critical care facilities.

Viruses, including the coronavirus, are relatively easy to capture and are retained on the air purification cartridge, removing them from the air and eliminating them as a health threat.

Along with airborne particulates and pathogens, airborne chemical compounds are caught up and absorbed in the air purification cartridge, also eliminating them as a health threat.

SecureAire’s effectiveness is further support by the recently released article published in the “American Journal of Infection Control”

What can be said regarding SecureAire’s Air Purification System capability of removing the Coronavirus from your home?

We cannot stop someone from bringing the Coronavirus into your home or spreading it by close contact with others.

What we can say, with confidence, is that SecureAire’s technology is proven in operating rooms and certified test laboratories to remove and destroy airborne pathogens, including bacteria and viruses, from the air that you breathe.

The “PACT” Effect

SecureAire Technology

SecureAire’s Technical approach is based upon a proprietary combination of Particle Conditioning and Particle

Collision Control better known as Particle Accelerated Collision Technology (PACT). PACT is the only Technology available in todays’ marketplace which makes airflow the dominant transport mechanism for small particulates, such as bacteria, viruses, allergens, TVOC, gases and odors. SecureAire’s unique system is applied to improve indoor air quality in a building or home, reducing or eliminating harmful particulates which can either cause sick building syndrome or worse, the spread of dangerous airborne pathogens. SecureAire is the only device that simultaneously increases the overall filtration efficiency (the capture rate of particulates/pathogens in the air) and has the potential to kill or inactivate these same dangerous organisms.

The company latest Technology Development is called Particle Guide Technology (PGT), which addresses the costly issue of static pressure, associated with today’s mechanical filtration systems.

SecureAire’s technology will prove to be an industry leader in the years to come as it has the ability to be applied to a wide variety of applications previously bound by the application of standard mechanical filtration, ion generation and other electrically enhanced technologies.

In summary, SecureAire is well positioned with its current Product and Technology Platforms and also continues to develop future “break-through” technologies in the air purification space.

Sensor Calibration

Sensor Calibration – Accurate Sensors Require Calibration:

Sensor Calibration

According to an article in the January 2016 ASHRAE Journal, Applying Demand Control Ventilation, “CO2 sensors are subject to calibration drift and accuracy issues over time. A field study on a campus building with CO2-based DCV found that differences between the commercial CO2 sensors used in buildings are significant. Periodic maintenance is essential to keep the readings of CO2 concentration accurate over time.”

At Aircuity, we couldn’t agree more and our bi-annual sensor exchange is a core element of our solution’s long-term accuracy. The Calibration Laboratory at our headquarters calibrates over 6,000 sensors annually. A team of 6 calibration technicians follow a regimented calibration process, which with a calibration verification phase when sensors are run for 1 to 5 days to eliminate programming or out of box failures. The newly calibrated sensors are shipped to Aircuity-certified technicians around the world who install them at local customers’ facilities.

Our sensor calibration process means fewer headaches for customers and a solution that building occupants and constituents can count on!
