What temperature actually kills bacteria?

Facilities such as hospitals, laboratories and food (handling) organizations require an absolutely clean working environment. The most common and effective anti-microbial agent is High Temperature High Pressure Steam. When we guarantee a 99, 9% bacteria (almost) free result, what temperature is required?

As we known, there are a big range of different bacteria groups. Most commonly known bacteria cannot live in temperature exceeding 140 degrees Fahrenheit (or 60 degree Celsius). In some cases, such as hospitals, the steam temperature has to go up to 250 degrees Fahrenheit (or 120 degree Celsius) in order to make sure a wider range of bacteria got killed. “Anything that is heated to over 120°C should be enough to kill all bacteria and even spores” (Dr. Jodi Lindsay)

Outside of hospitals and food industry, the DRY Steam is also getting popular as a cleaning method, mainly because it is efficient and environmentally friendly. In daily household, to limit hazard chemicals or at least decrease the detergent usage amount to minimum is a fair request for the sake of health.

The highly heated steam kills viruses, bacteria, allergens, mold, mildew as well as dust mites and their eggs. However, to make sure (upholstery) furniture such as mattresses and cushions are getting properly sanitized, High Pressurized Steam is another necessary factor. Pressure equal or greater than 15PSI is recognized as most effective.

With the help of high pressure, vapor steam can reach into even the smallest cracks and crevices where other cleaning tools cannot reach. As conclusion, it is the combination of heat and pressure that destroys the organisms.

In the end, there is a brief specification of what AllerX Steam Cleaning System V8 offers.

  • Operative pressure 5 bar (72 PSI)
  • Steam reaches temperature of 150 °C (300 degrees Fahrenheit)

** How many PSI in 1 bar? The answer is 14.5

How many degree Fahrenheit in 1 degree Celsius? The answer is 1.8
