Yes, Ultraviolet (UV) Sanitizers for pools do work. They use the same wavelength of UV light (254nm) that has been used worldwide for over 60 years to purify drinking water. For a more specific explanation of how they work see below.

The UV254 Sanitizer uses Ultraviolet Technology at a wavelength of 254 nanometers (nm) which does not produce ozone. Basically, ultraviolet light (UV) reacts with the DNA and RNA of living things to destroy the activity of these important molecules.

In particular, the UV254 Sanitizer produces ultraviolet radiation at a particular wavelength (254 nanometers or 253.7 more precisely) which is a good match for inactivating the DNA or RNA of pathogens - the various kinds of microorganisms that do us harm.

In a bit more detail, physics tells us that ultraviolet radiation is a form of electromagnetic radiation. One basic characteristic of this radiation is its wavelength which is often measured in nanometers (one billionth of a meter, abbreviated nm). The different wavelengths of radiation form what we call the electromagnetic spectrum. The spectrum can be pictured as consisting of visible light waves in the middle with infrared, microwave and radio waves having longer wavelengths and ultraviolet, x-ray and gamma rays having shorter wavelengths.

The visible light we see with our eyes varies from the violet with a wavelength just above 400 nm to red which has a wavelength up to 700 nm. Ultraviolet is called just that - it's beyond violet with wavelengths below what we can see. There is a relationship between the wavelength of light and its energy … shorter wavelengths have more energy. That's just a fact that we won't get into here.

The ultraviolet part of the spectrum is conveniently labeled divided into different parts labeled UVA (wavelengths from 400 down to 315 nm), UVB (315-280 nm), UVC (280-200 nm) and extreme UV (below 200 nm). This means that the shorter wavelength UVC rays have a higher energy than the UVA or UVB radiation. The UV254 Sanitizer works right in this higher UVC range.

Now consider a bit of Biology. Living things are made up of complex molecules. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are two of these. They are involved in providing the genetic code and important cell protein manufacture essential to living things. A molecule, including DNA and RNA, is a string of atoms held together by what scientists call chemical bonds. Each chemical bond is associated with a particular energy.

It is an accident of evolution or just bad luck but the energy of some chemical bonds in DNA and RNA matches that of the UVC radiation. The energy from the radiation is just right to break some of the chemical bonds. It's like breaking a twig - we put our energy into bending the twig until it breaks.

The result is that the microorganisms can not reproduce and may be killed. The UV254 Sanitizer uses radiation at 254 nm wavelength, right in the middle of the UVC part of the spectrum so is effective in inactivating the wide variety of pathogens that are important to pool owners.

What are the pros and cons of ultraviolet pool sanitizers?

Ultraviolet sanitizers work by creating ozone, which is far more effective than chlorine as a sanitizer. However ultraviolet does not produce as much ozone as carona discharge systems. With ozone you will use less chlorine. I don't know a downside of using ozone.

Alcohol based or Non-alcohol based Hand Sanitizers work well?

Hi, well I recently did a science fair project and with my results I found that non-alcohol based sanitizers work better then alcohol based sanitizers. However, they do not work that well, hand sanitizers only kill the germs, consequently, they are still there, dead or alive. Almanza, associate professor of restaurant, hotel, institutional and tourism management, says "the typical hand sanitizer, which is usually alcohol-based, strips the skin of the outer layer of oil, which normally prevents resident bacteria from coming to the surface." Hopefully this helps! ;)


Can ultraviolet sanitizers be used on food to prevent food poisoning?

Ultraviolet sanitizers only help kill off organisms on the surface of the food where they can be exposed to the ultraviolet light. Since many types of organisms that cause food poisoning are mixed into or are on the side of the food away from the light, the ultraviolet light cannot reach them and they remain intact and able to cause their nasty effects. Gamma radiation, which, like ultraviolet light is a form of electromagnetic radiation, can penetrate food and kill even organisms that are deep inside. As a result, irradiation with gamma rays is sometimes used to sanitize/sterilize food. Since ultraviolet light can kill those organisms that it can shine on, it is still useful for providing a more sanitary environment than one without it. It can sanitize surfaces where food is placed so that the food will not pick up germs, parasites, etc. from the surface. It won't totally prevent food poisoning, but it can lower the risk some.


Do sanitizers contain dog drool?

No. Sanitizers can not contain any type of dog drool because it is made of bacteria from the mouth.

What do common sanitizers use?

Commercial hand sanitizers, such as Purell, use isopropyl alcohol (rubbing alcohol) as their active ingredient.

There are several classes of industrial sanitizers, including chlorine-based, quaternary ammonia-based, and acid-based.


Why does hand soaps and sanitizers prevent the growth of bread mold?

Hand soaps and hand sanitizers prevent the growth of bread mold because bread mold is a bacteria and the PH level of soap and the alcohol in hand sanitizers can prevent the growth of the bread mold.
