Cold Plasma Technology

A Dynamic, Sanitary Solution

Cold plasma technology represents an incredibly versatile solution in bathroom hygiene. When properly implemented in the SANITIZE + DRY hand dryer, this technology is capable of near instant neutralization of 99.99% of all common germs as well as tested to successfully kill the following bacteria and viruses[1]:

  • Influenza A
  • SARS-CoV-2
  • Human Rhinovirus (HRV)
  • E-coli
  • Staph
  • MRSA
  • Norovirus
  • Enterococcus faecium

Cold plasma technology utilized in hand dryers can also be just as effective at sanitizing both dry and wet surfaces and even extend that sanitizing effect to things like jewelry, keys, smart devices, or anything else placed near the outlet of the dryer.

What is Cold Plasma?

Plasma is the fourth state of matter after solids, liquids and gases. Plasma can be thought of as highly energized gas, and the most well-known forms of plasma include the sun, or the energy produced during lightning strikes. 

Cold atmospheric plasma is super-energized air that includes electrons, ions, and short-lived reactive molecules that kill bacteria and viruses. It is specifically referred to as “cold” plasma because the energized air remains at ambient temperature.  

How Does Cold Plasma Work?

A cold plasma generator within the dryer energizes the air flowing through the dryer, raising it to the plasma state and producing special reactive molecules. It is these molecules that attack the structures and vital processes of viruses and bacteria, rendering them incapable of surviving or spreading.

There are several different approaches to generating cold plasma, and not all of them are equally effective at killing germs. With the right plasma technology, enough reactive molecules can be generated to eliminate bacteria  and viruses on contact with 99.99% efficacy: including antibiotic resistant bacterial strains. 

Reactive Molecules in Nature

Our environment already includes natural and manmade sources of some of the same reactive molecules found in plasma. As an example, plants produce reactive molecules during photosynthesis. Similarly, the human body also produces some of the same reactive molecules as part of normal metabolism and immune responses to help fight against infections.

1 Disclaimer: Kills 99.99% of common bacteria and viruses in the drying air and on exposed surfaces. Laboratory tests confirm 99.99% efficacy against Influenza A (H1N1), SARS-CoV-2 (COVID-19), Human rhinovirus (common cold), Escherichia coli (E. coli), Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus (MRSA), Norovirus and Enterococcus faecium. Results indicate broad efficacy, though effectiveness may vary against specific pathogens.
