It has been proven in a study conducted by Marie Hagbom that ionizer devices are effective in the prevention of the airborne transmitted influenza A virus infection. An active negative ionizer prevented 100 percent of guinea pigs from the infection. Additionally, the device effectively captured airborne transmitted calicivirus, rotavirus, and the influenza virus and had recovery rates of 21 percent after 40 minutes in a 19 m³ room.
The ionizer generates negative ions that render airborne particles and electrostatically attracts them to a positively charged collector plate. The trapped viruses are identified by reverse transcription-quantitative real-time PCR. This device enables unique possibilities for the rapid and simple removal of viruses from the air and offers the possibility to simultaneously identify and prevent the airborne transmission of viruses.
Currently, there is an urgent need for simple, portable, and sensitive devices to collect, eliminate, and identify airborne viruses. This is needed to rapidly detect and prevent outbreaks and the spread of infectious diseases. The most common infectious diseases are spread by the droplets created from coughing, sneezing, and vomiting.
Ozone gas has been proven to inactivate norovirus and can be used in empty rooms for the decontamination of surfaces, however, it is toxic around humans. Generating negative ions has been previously shown to reduce the transmission of the Newcastle virus and several kinds of bacteria in animal experimentation.
A negative ionizer does not produce detectable levels of ozone gas, therefore, it is safe to use in any environment.
The negative ionizer is an effective way to collect and eliminate cat allergens from the air. Rotavirus, calicivirus, and influenza virus particles exposed to the ionizing device were attracted to the collector plate and subsequently identified by electron microscopy and reverse transcription-quantitative real-time PCR techniques.
