> There have always been harmful particles in the air...
...but since the Covid pandemic, we’ve all been paying them a bit more attention than we used to. Vaccinations can stop you becoming severely ill with viruses like Covid and ‘flu, but they don’t necessarily stop you from catching them in the first place, and they can’t do anything about annoying pollen or dangerous bacteria.
> UV-C irradiation...
...is a highly effective way of combating airborne infections caused by contaminated aerosols. The technique has been known about for around 100 years, and has been used primarily in food production and medical settings. In recent times, the Covid-19 pandemic has inspired people to find new applications for this proven technology.
Dealing with viruses, bacteria, pollen and germs is a major challenge, especially indoors. Luckily, UV-C radiation is one of the most effective ways of getting rid of them. Exposing microbes to UV-C radiation breaks their molecular structure (i.e., their DNA and RNA), leaving it inactive.
Irradiating the air with UV-C light isn’t just effective, convenient, and environmentally-friendly, either. Since it requires no filters or chemicals, it’s also a highly affordable method of disinfection.

Exposing microorganisms to UVC radiation inactivates their DNA and RNA. Irradiation with UVC light has become an effective, convenient, affordable and environmentally friendly form of decontamination. UVC disinfection requires no human labour and consumes no chemical agents. Consequently, it is cost-efficient and ecologically sound. It also minimises the consumption of chemical disinfectants.
We use UV-C disinfection systems to purify the air.
They work by sucking the air into the disinfection unit using fans. The air is then channelled into the irradiation chamber, where it is exposed to a set dose of radiation.
Any microbes in the air that emerges from the other end are 99,9% deactivated (take a look at our test report for full details).
It’s also absolutely safe – the report proves there’s no risk of radiation leaking from the unit.
->Can other manufacturers say the same?
> Why not just use an air filter?
It’s true that a filter system with a HEPA-standard filter ought to do the job. But there’s a problem: in order to purify the required volume of air every hour, these systems have to be big and bulky – there’s just no getting away from it. Many of them are also pretty loud, and the filters need to be changed regularly. Human nature being what it is, people tend to forget to replace the filters the second or third time around. On top of all that, HEPA filters aren’t exactly cheap, either.
> Time as a factor in UV-C irradiation
The time factor is very important for UV-C irradiation of the air. UV-C irradiation of the extracted air is noiseless – you only hear the fans inside the housing. For the viruses and mutant forms that currently pose a threat to us, barely two seconds of intensive UV-C irradiation is required. The time element is absolutely critical, according to the experts. Most systems currently available on the market blow the air over the integrated UV-C tubes in little more than half a second. This is far too short a duration. The DNA structure of these viruses is not completely destroyed until just under 2 SECONDS have elapsed. This is the way to neutralise SARS viruses and their mutant forms. As a bonus, the system also eliminates the various influenza viruses that make their way to the northern hemisphere every winter.
Why the mutant forms as well?
Because they are variants of a virus, and virus elimination is our business.
> Of course, our competitors would say all this, too...
…but we can prove it. Our systems have been tested for effectiveness, airflow, noise levels and more by a team of researchers specialising in UV radiation, ventilation and virology, so we know they work.
