Now that the isolation and social distancing rules are slowly being removed, it is very important that we take actions to minimize bacteria and viruses from infecting a lot of people in the same room.

According to studies, some germ-laden droplets expelled by people with bacterial or viral infections when they breathe, talk, cough, or sneeze can remain suspended in the air for up to two hours.  When inhaled these can potentially cause life threatening infections.

STL's newest VK series of air processors use powerful European made Philips Sterilamp® UVC emitters to kill over 99.9% of air borne bacteria and viruses (including coronaviruses) in the air processed. Minimal power consumption means the units can be kept running 24/7 to provide nonstop protection in the home, clinic, restaurant, school, shop, or office.

​

Bacteria and viruses passing through STL’s VK3000 are exposed to over 480 W s/m2 of UVC power (this number is known as the Effective Dosage). For reference, below are the Effective Dosages needed to kill 99.9% of several commonly found bacteria and viruses*:

• Dysentery: 65.8 W s/m2

• Tuberculosis: 181.8 W s/ m2

• E. Coli: 89.7 W s/m2

• Salmonella: 119.1 W s/m2

• Hepatitis A: 215.9 W s/m2

• Influenza: 107.9 W s/m2
