Air sterilizers and purifiers help minimize the number of germs we may inhale day in and day out.
But... if those devices are not maintained well, they can actually worsen the problem.
Scientists, however, believe they may have found a solution to lessen the maintenance process.
Kim Hyun-bin reports.
This is an air sterilizer installed in an elementary school classroom.
The filter is full of all sorts of dust and germ particles.
It′s a problem that schools, hospitals and a whole host of public facilities are faced with.
If the filter is not maintained, the germs will multiply at a rapid rate.
But a group of international scientists, including Korean experts, has developed a specialized air filter that aims to make the process easier.
The key is its silver nanotechnology that coats the filter′s surface, sterilizing and killing E. Coli and other germs that can cause health problems.
The effect can be seen through a microscope.
"The nanotechnology is similar in size to the bacteria and as soon as contact is made,... the germs are ripped apart."
To test the filter,... researchers blew in the germs at a speed of 2 meters per second,... but the nanotechnology wouldn′t budge.
"Even with the A/C on full blast, the filter continued doing its job,... killing all the germs that passed through."
Germs can lead to any number of diseases, but this breakthrough is increasing hopes that their spread can be mitigated.
