Hello! We're Strl Biosystems. 

We make Strl® AIR™. It destroys pathogens such as the Novel Coronavirus continuously in the air. 

COVID-19 is airborne.

Leading public health experts and global institutions all agree that COVID-19 is airborne. The need for continuous indoor disinfection has never been higher.

"The virus can spread from an infected person’s mouth or nose in small liquid particles when they cough, sneeze, speak, sing or breathe. These particles range from larger respiratory droplets to smaller aerosols."

The principal mode by which people are infected with SARS-CoV-2 (the virus that causes COVID-19) is through exposure to respiratory droplets carrying infectious virus.


"transmission of SARS-CoV-2 is higher indoors than outdoors and is substantially reduced by indoor ventilation. Both observations support a predominantly airborne route of transmission"

What are sterile zones?

Sterile zones are areas where there are virtually no germs present. This can be achieved by many methods including fumigation using chemicals, exposure to UV radiation and also by using tools like Strl® Air Continuous Disinfection Systems.

Until now Sterile Zones were maintained only in very critical areas such as Hospitals, Biological Laboratories or Pharmaceutical Factories due to high cost factor. 

Now, with our breakthrough product Strl® AIR™, it is now possible (and affordable) to create a Sterile Zone right in your spaces.
