Germicidal Light

How long does it take for Germicidal UV-C lamp to kill germs (I have a 36 watt light)?

Do the UV-C lights in my furnace actually work at killing germs/bacteria or are they like most things, to good to be true and cost big $. I know that UV-C does actually kill germs but its not instantly in most cases. I'm trying to figure out if the air in an air duct passing by the light would actually be enough time to really kill germs. Any educated input on the matter would be appreciated.

Different germs required different amounts of time under the light. For example, some viruses can be killed after only a few seconds or minutes, while most bacteria require at least 20 minutes to kill.

The air in a duct passing under the light (if the air is constantly moving) would kill some germs, but not most.
I work in a microbiology lab, and we leave the UV light on for at least 20 minutes when we want to decontaminate something.

I would not spend a bunch of money on such a light for my home, just get a really good filter instead. Additionally, most of the germs in your home that would make you sick will be found on surfaces (door knobs, light switches, etc), unless someone in the house currently has a respiratory infection (including the common cold).

The Ultra-violet lamps of a water treatment by UV produce UV-C. No UV-C rays from the sun ever come into contact with life on earth, they are completely filtered by the atmosphere. However, man produced UV-C rays do. The UV-C lamps are used in biology laboratory for the effects of germicides. Those UV-C have a radiation with an intensity far greater than the sunlight and are used in the treatment of water to sterilize it.

The UV filter can kill most bacteria and viruses in water. However, this type of water treatment does not completely purify water. Indeed, it does not treat the water against chemical pollutants, for example. The installation of systems ultra-violet water purification are therefore combined with other system of water purification, UV light generally has no impact on chlorine, heavy metals and other chemical contaminants.

How UV water treatment system works?

The water purification by ultra-violet uses a UV light source (lamp), which is enclosed in a transparent protective sleeve (usually quartz). The lamp is mounted in such a way that water passes through the filter by a room flow. The water is then exposed to UV-C rays. When harmful microbes are exposed to UV rays, their nucleic acid absorbs UV energy, which blurs the structure of DNA. The cell is rendered sterile and can no longer reproduce. The cell is now considered dead and no longer a threat.

Why use an ultra-violet water purification system?

UV water purification technology is probably the most cost-effective and most efficient on the market today. It allows homeowners and business owners to remove a range of biological contaminants in their water supply. The UV water treatment offers many advantages over other forms of water treatment for microbiological contaminants. Most importantly, it leaves no chemical in water, it produces no by-product, and it does not change the taste, pH, or other properties of water. Consequently, in addition to producing safe drinking water, it is not harmful to your plumbing and septic system.

The UV treatment is an excellent choice for eliminating biological contamination of most waters. If your home or business requires an additional filtration or if you have a source of private untreated water (rainwater, lake water, wells etc.). The unique objective of UV water treatment system is to kill harmful biological contaminants.

No microorganism can resist to Ultra Violet, unlike the treatment of water with chlorine. The UV is known to be highly effective against bacteria, viruses and algae. In practice, bacteria and viruses are the cause of many diseases carried by waters. Of these viruses, the hepatitis virus and Legionnaires have demonstrated ability to survive for considerable periods to treatment with chlorine, but are easily removed by a UV treatment. For most microorganisms, the effectiveness of UV against microbiological contaminants such as bacteria and viruses generally exceeds 99.99%.

The UV water treatment is very effective (+ 99.99%) against; salmonella (typhoid fever), Salmonella enteritidis (gastroenteritis), vibrio cholerae (cholera) ), mycobacterium tuberculosis (TB), Legionella pneumophila (Legionella), influenza virus, polio, and Hepatitus.
