UVC Air purifier against Corona (Covid-19) virus

So far, 2020 has been a year with many challenging obstacles and unprecedented changes due to the pandemic. Recent reports have suggested that it will take several years until a vaccine is available. Until then, we have to find a way to eliminate the virus from the air. One of them is with UVC light which wavelength is the most effective for killing microorganisms, like the Corona (Covid-19) virus.

UVC Light can destroy the Corona (Covid-19) virus

Researchers first reported the Corona (Covid-19) virus in December 2019. Then the World Health Organization categorized it as a pandemic in March 2020. 

Despite great efforts to contain the spread of the disease, it has spread worldwide, costing the lives of countless people and crimping the health infrastructure of dozens of countries. 

Researchers believe that the transmission of the virus to be both through direct contact and airborne routes. Studies suggest that the virus' survival in aerosols can last for at least 3 hours. Given the rapid spread of the Coronavirus, we must explore practical reduction strategies to destroy the virus in public places and thus reducing the contamination rate.

One of them is with ultraviolet C (UVC) light exposure, which is a direct antimicrobial approach. UVC light is a known disinfectant for air, water, and other surfaces. UVC radiation has been used for almost 100 years to reduce the spread of bacteria, such as tuberculosis and to decrease infection rates after surgeries.

More recent studies have shown that UVC light can destroy the outer protein coating of the Coronavirus. The destruction ultimately leads to the destruction of the virus.


The unprecedented widespread mortality and morbidity caused by SARS-CoV-2 (the virus that causes Covid-19) have encouraged several renowned universities and intuitions. Boston University and RIVM have shed some light on the respiratory illness.

UVC air purifier protection against aerosols

The main cause by which people get infected with SARS-CoV-2 is through exposure to respiratory droplets - aerosols - carrying the infectious virus.

People produce aerosols when they breathe, speak, sing, cough, and sneeze.

There are many strategies to reduce the spread of the airborne virus that's in aerosols. But one goal must be to decrease or preferably destroy the viral components in the air.

As a result, we need to consider the impact of ventilation and UV radiation. While the easiest way is by opening a window or through sunlight, these methods depend on infrastructure and mother nature. Thus, limiting our options.

UVC air purifier: ViroPower

Luckily, there UVC air purifiers, like the ViroPower, that draws in the surrounding contaminated air and kills airborne viruses like the Corona (Covid-19) virus.

The ViroPower is a mobile UVC light air purifier device with Dust and HEPA filters.

First, the ViroPower draws in the surrounding contaminated air. This air goes through the Dust filter and HEPA filter to get rid of dust mites, pollen and pet dander, and other allergens.

Then the air goes through a special, isolated compartment that houses UVC lamps, where the light coming from these tubes destroys the airborne pathogens and microorganisms like, Corona (Covid-19) virus.

Indoor spaces are a breeding ground for viruses and bacteria. But can be reduced by eliminating the virus that's in the aerosols with air purifiers that contain UVC light, like the ViroPower.

What about devices with ionizer sterilizers?

An air purifier with an ionizer sterilizer can work to trap viruses from the air. There is indeed scientific evidence to support that it works against viruses. However, an ionizer produces ozone (O3: three oxygen atoms). And that is poisonous to humans and animals. As a result, the UVC lamps inside the ViroPower don't contain ionizer sterilizers and thus making them are ozone-free.

UVC air purifier vs Plasma air purifier

People are increasingly concerned with providing their loved ones, employees, and customers with the cleanest indoor air possible. Thankfully, technology is keeping up with that demand, mainly due to the Corona (Covid-19) virus. Among the latest developments are plasma and UVC air purifiers. They're an option to consider if you're looking for ways to improve the indoor air quality.

A plasma purifier forms ions as air circulates over the ionization tubes. The ions that the plasma purifier produces purifies the air by reducing particles in the air, sterilizing bacteria and mold, and control odors.

Plasma purifiers can remove most household pollutants and allergens. So, they compare quite favourably to other types of air cleaners and purifiers.

A UVC air purifier draws in the air and kills 99.9% of viruses and bacteria. Not only that, UVC air purifiers, like the ViroPower 6000 have dust and HEPA filters that remove pollen and dust.

In the end, plasma air purifiers do indeed remove contaminants and allergens from in the air. However, a UVC air purifier does the same, and it goes the extra step to destroy microorganisms, like mold, bacteria and viruses.
