Safety filter technology

A groundbreaking technology from UV Medico creates the safest Far UV-C lamp on the market.

The end of side-emissions

Far UV-C light of a 222 nanometres wavelength is an almost perfect tool for disinfection.
However, until recently one significant safety concern remained. 

The disinfecting potential of Far UV-C light has been recognized for years, but researchers and companies in the sterilisation industry have continued to struggle with one particular safety concern: even when a Far UV-C lamp is designed to emit Far UV-C light of 222 nanometres (nm) only, the nature of UV-C light is that the lamp will inevitably emit small amounts of secondary emissions in other wavelengths as well.

These secondary emissions in other wavelengths than 222 nm can potentially be harmful to human tissue and eyes.

However, with the patented safety filter technology, we are now able to eliminate that safety concern, making UV222 a major breakthrough in the market.

How the filter works

Its unique safety filter technology, Care222® from Ushio Inc., makes UV222 safer than any other disinfection lamp on the market. 

The safety filter technology in the lamp from UV Medico is a thin filter that only lets through light at around 222 nm and blocks all other unwanted radiation. 

It works much in the same way as sunglasses with UV protection, blocking the UV radiation from passing through and entering the environment, completely eliminating dangerous longer wavelengths and making the light from the lamp safe. 

First non-harmful Far UV-C light

The Far UV-C lamp UV222 from UV Medico is the first non-harmful UV lamp

UV222 emits a type of UV-C light that, when applied in the correct doses and in combination with the patented safety filter technology, is harmless to humans. 

▸ No penetration of human skin
Numerous independent research projects have demonstrated that Far UV-C light at 222 nm, when emitted in the correct doses, can deactivate pathogens while remaining unable to penetrate the outer layer of mammalian skin or the outer tear layer of the eye. 

▸ No harmful doses 
UV222 emits Far UV-C light at a wavelength of 222 nm in harmless doses. The lamp is in full compliance with local, European, and global guidelines. 

UV222 is, therefore, a key component in preventing infectious diseases from affecting individuals, organisations, and companies, and disrupting society as a whole. 


All of this is achieved with:
  • No risk of damage to human tissue. 
  • No risk of damage to human eyes. 
  • No risk of dangerous wavelengths thanks to the patented safety filter technology (Care222).  
  • No risk of harmful Far UV-C high doses – the lamp is controlled by UV Medico’s intelligent software and configured by a certified installer.
