Is the Swine Flu (H1N1) Virus Killed by Ultraviolet light?
Viruses are not alive the way a plant or an animal is alive. They do not consume, excrete waste product, grow, or react to their environment. They do however reproduce themselves, but only in a host cell. A specific type of virus will only reproduce in a specific type of host cell. There are viruses that affect just about every type of organism. It may be better to think of viruses as active and de-activated rather than alive or dead.
Viruses are the cause of Swine Flu (H1N1), other types of influenza, ebola, HIV, rabies, herpes, common cold, measles, chicken pox, polio, and more.
Ultraviolet light used in water purifiers and air filters does deactivate or kill viruses. Ultraviolet light represents the frequency of light between 200 nanometers (nm) and 400 nm. You can’t see it with the naked eye. The most effective frequency for killing viruses and bacteria is between 254 nm and 265 nm.
The viruses are deactivated because the light causes genetic damage. The virus can no longer reproduce itself. Ultraviolet lights used in home filters need to be wiped off every six months. Some systems are closed and signal that the bulb needs to be changed. They use about the same amount of energy as a 40 watt incandescent bulb.
Should you use an air filter that uses ultraviolet light? That depends on how often you’re exposed to people who may be sick, how much the air in your home is circulated, and other factors. Many modern homes are virtually sealed air systems in the winter when the heat is on or during the summer with air conditioning. This closed system doesn’t allow the viruses to dissipate but keeps them trapped within your home
