The air we breath, free from virus & bacterias with our Upper Room UVc fixtures

Unique disinfection system which avoids infections among persons

Eliminating  virus and bacteria in the air we breathe with our Upper Room ultraviolet disinfection fixtures.

With our fixtures we get full indoor air disinfection while people is present, with no need to interfere in building normal activities.
This is specially relevant in offices, schools, hotels, restaurants, shopping centers, as in any other indoor space where persons gather.

How it works?

Our Upper Room Air Purification Fixtures are installed on the upper side of rooms, delivering Ultraviolet C Light precisely just in this upper zone.

The Indoor Air we breathe carries pathogens coming from people coughing, sneezing, talking and breathing in that indoor space. Furthermore, Indoor Air moves up and down in the room in a convective way, contributing to virus, bacteria and fungus dispersion all over the room.
When this infectious air goes up, it reaches the UVc Light emitted by our fixtures at the upper zone, inactivating airborne microorganisms in just seconds.

Safe system suitable with people

Our Upper Room Air Purifier Fixtures, emit Ultraviolet C Light with efficacy and safety, just in the Upper Zone, inactivating airborne viruses, bacteria and fungus, in seconds, and with no affection for people present indoor. No need to take people out while disinfecting the air.

Unique system which avoids airborne infections among people

Indoor Airborne Viruses and Bacteria, which come from infected persons, can be breath by non infected persons sharing the same indoor space, with subsequent risk of infection development. Examples of this fact are found in Airborne Diseases as Influenza, Measles, SARS Coronavirus, MERS, Tuberculosis, Chickenpox and Pneumonia, among many others.
Our Upper Room Ultraviolet Fixtures, purify the whole Indoor Air Volume directly and continuously, reducing contagions between persons by providing Healthy Indoor Air.
