Does the UV light used in the bathroom disinfection lamp work?
It can be used, but it should be noted that because ultraviolet
rays are harmful to the eyes and skin, it should be opened in the
state of no one in the room, about 30 minutes each time, and then
open the window for ventilation.
Ningbo Youwei Optoelectronics Standard UV lamps have a usage time
of 8,000 to 10,000 hours, and long-lived ones are 13,000 hours. The
lamp tube should be replaced after the usage time.
Another suggestion: the opening time should not be too long, it is
best to enable the UV lamp when no one is in the state, and the
window should be opened immediately after use for ventilation.
Is it useful to use ultraviolet rays for bathroom disinfection
lamps?
Ultraviolet disinfection technology has unparalleled sterilization
efficiency of other technologies. The sterilization efficiency can
reach 99%-99.9%. It generally takes 20 minutes to 1 hour for
traditional chemical disinfection methods such as disinfection and
ozone to achieve the sterilization effect of ultraviolet C.
Usually used for sterilization and disinfection in hospitals,
industries and other fields, the effect of application is naturally
no doubt! Due to the wide range of applications, we recommend that
you use the following situations at home
1. Someone at home (especially with infectious or respiratory
disease)
2, the elderly at home
3. There are infants and young children at home
4. I live in a basement or semi-basement, which is not ventilated
and rarely gets access to sunlight.
5. Have pets or other small animals at home
6. The resistance of the family members is weak, and it is always
easy to catch a cold or have diarrhea
7. Family members have skin problems." "How is UVC light currently
used to kill the new coronavirus?
Because it can effectively inactivate the new coronavirus without
using chemicals, UVC light is an attractive option for
disinfection. Special lamps that emit UVC light are typically used
for this purpose.
Currently, the use of UVC light for disinfection is mostly limited
to healthcare settings to disinfect things like:
surfaces
equipment
operating rooms
personal protective equipment (PPE), such as N95 face masks
What are the downsides to UVC light?
One of the downsides to UVC light is that it needs direct contact
to be helpful. That means that if an area is in shadow or covered
by dust, UVC light will be less effective at killing germs that may
be present.
While UVC light can quickly kill SARS-CoV-2, the Food and Drug
Administration (FDA)Trusted Source notes some additional risks for
using it at home:
The optimal length of exposure, wavelength, and dose of UVC light
for killing SARS-CoV-2 is yet to be determined.
Exposure to some types of UVC light can damage your skin or eyes.
The types of UVC light lamps sold for at-home use are often lower
in intensity. That means it may take a longer time to kill germs.
UVC light lamps can potentially contain mercury or produce ozone,
both of which can be harmful to humans.
It’s possible that prolonged exposure to UVC light can cause
materials like textiles, plastics, or polymers to degrade.
Far-UVC light may be a potentially safer option for disinfection.
ResearchTrusted Source has indicated that, unlike other types of
UVC light, it doesn’t appear to penetrate the outer layers of the
skin or eye. However, further safety studies are needed.
Scientists are exploring specific wavelengths of UVC light that are
safe for humans.
Most UVC lamps emit a broad spectrum of UVC wavelengths (200–280
nanometers) or a specific wavelength of 254 nanometers. Studies
have shown that shorter wavelengths of UVC light (such as 222
nanometers) can also inactivate airborne viruses (including
SARS-CoV-2) and other microorganisms. This wavelength of UVC light
is often referred to as far-UVC light and may be safe to use in
occupied spaces. In studies on mice and rats, no damage to the skin
or eyes was found from long-range UVC light. However, more research
is needed to verify that people can be exposed to this wavelength
for a period of time without harmful side effects." "Applications
