Air disinfection
With UV-C

UV-C Disinfection of the air we breathe

Cleaning the air around us properly

If you have seen someone trying to “deep clean” a room with a spray bottle it is evident it is NOT cleaning the air! UV-C is used for air disinfection in virtually every application, because there are always situations where microorganisms in the air can cause a problem and make people ill. For example in offices and schools, public transportation, entertainment venues, but also in the food processing- and agricultural industry. Airborne microorganisms can easily and effectively be inactivated by UV-C light.

Our Philips UV-C disinfection upper air wall mount luminaires inactivated 99.99% of SARS-COV-2, the virus responsible for the COVID-19 disease, in the air of a room within 10 minutes. At 20 minutes, the virus was below detectable levels. Please find here the Innovative Bioanalysis report for more information on the results of UV-C disinfection in air.

Upper air luminaires

In rooms where people are present, upper air UV-C disinfection luminaires can be installed to continuously disinfect air. These systems are usually installed at a height of above 2,4 m. By making use of parabolic reflectors, and non-reflective lamellas, the UVGI can be concentrated in a zone. In this zone a high intensity UV-C is realized without having too high intensities below 2,0 m. Because of the presence of natural or mechanical ventilation in the room, the contaminated room-air will pass through the UV-C zone and thus will be disinfected. Our Philips UV-C disinfection upper air luminaires inactivate up to 99.9% of virus Coliphage φX1742 in air within 10 minutes in a room with sufficient air circulation.2  Please find here the Intertek report for more information on the results of UV-C disinfection in air.

Open UV luminaires

By installing open UV-C disinfection fixtures on walls or ceilings, the entire volume of air and the airborne microorganisms are directly exposed to high intensities of UV-C light. As a result, strong reduction in the number of microorganisms is achieved very quickly. An additional advantage is that directly exposed surfaces are also disinfected. In this form of air disinfection, no people or animals can be present without protective measures.

Air conditioning systems

In air conditioning systems, high output(HO) UV lamps will keep the cooling coil free from biofilm. Combined with photocatalytic oxidation they can also removes VCOs such as odors. Depending on the size of your system, this will require up to 150W of power in commercial applications, or up to 25W in residential applications.

So many applications

And don’t stop there ….. if there is air! Air disinfection can play an important role in a broad range of applications such as hospitals, schools, offices, industry, (food) retail and museums.
