Either by direct destruction or the alteration of the organism's DNA or RNA. Either way ensures a halt to the pathogen's* ability to reproduce and infect.

UV light kills the bacteria by attacking the DNA of a cell preventing cellular division. It attacks the RNA in viruses (preventing replication). Ozone ruptures the cytoplasmic membrane in bacteria cells "lysing" the cell wall. It attacks the RNA in viruses (preventing replication). PHI cells combines both methods.

UV-C is the invisible, ultraviolet, C-band radiation that makes up part of the sun's light spectrum. By altering the DNA and RNA and effectively sterilizing the organisms, the UV-C light prevents growth and germination of microorganisms. Once sterilized, they cannot reproduce and with their short life cycles, they are successfully killed.

Bacteria are single-celled organisms usually found all over the inside and outside of our bodies, except in the blood and spinal fluid. Many bacteria are not harmful. In fact, some are actually beneficial. However, disease-causing bacteria trigger illnesses, such as strep throat and some ear infections. Viruses are even smaller than bacteria. A virus cannot survive outside the body's cells. It causes illnesses by invading healthy cells and reproducing.

Kleenex Anti-Viral Tissues are a facial tissue product and are designed to kill common cold and flu viruses* that are expelled into the tissue from a runny nose, a cough or a sneeze. Therefore, this product was not tested against bacteria.

Ultraviolet (UV) rays are located just past the violet portion of the visible light spectrum; sunlight is the main source. UV light is broken into three different types: UVA, UVB and UVC. UVA has longer wavelengths and passes through glass easily; experts disagree about whether or not UVA damages the eyes. UVB rays are the most dangerous, making sunglasses and sunscreen a must; they don't go through glass. UVC rays do not reach the Earth because its atmosphere blocks them.

Most people think that they're only at risk when they're outside on a sunny day, but UV light can go right through clouds, so it doesn't matter if the sky is overcast. The sun's rays are strongest between 10 am and 2 pm. Glare and reflections can give you trouble, so have your sunglasses ready if you'll be around snow, water or sand, or if you'll be driving (windshields are a big glare source).

All Sterilight systems are rated for a 4-log inactivation of bacteria, viruses and protozoan cysts under specific conditions. This rating is at a specific flow rate, and water quality. It is a good idea to have your water microbiologically tested prior to installing a UV system.

Several safety measures protect service technicians and homeowners from eye or skin UV exposure, including a lamp shutoff switch, and a sight glass for safe and easy lamp inspection. A protective cover with a safety interlock switch immediately deactivates the lamp before the service technician or homeowner can access or service the unit. The effectiveness of germicidal UV-C is limited once molds, which are more resistant to UV energy than airborne bacteria, have already formed on surfaces.

The purpose of UV light is for bacterial disinfecting. UV light itself loses much of its effectiveness after the first 6 months of usage and should be replaced often, which is of course an expensive proposition. Also, the glass tube that the water travels through in order that it can be exposed to the UV light develops a film on it after only a few months, which greatly lessens the effectiveness of the UV light on the water that passes through the tube.

Most definitely. The EPA and Homeland Security have tested the Bio-Wall and on a single pass, it killed 93% of anthrax surrogate, 99.97% of spore-producing bacteria and 99% of a common hospital virus.

Firstly, viruses and bacteria are filtered and impregnated in the silverised activated carbon filter compartment. Through Ionization, the bacteria and viruses are further eliminated and finally they are not able to survive in the abundance negative-charged ions Alkaline Antioxidant Water.

A virus is a poison and the term is applied to a group of infective agents which are so small they are able to pass through the pores of collodian filters. They are responsible for some of the most important diseases affecting mankind, e.g. influenza, poliomyelitis, smallpox and yellow fever. A virus is normally not treatable with antibiotics. Viruses are transmitted both by physical contact as well as through the air. They are normally invisible.

Ultraviolet light kills potentially dangerous organisms and pathogens by disrupting the DNA structure of their cells. The Halo UVX Ultraviolet Vacuum and its patent-pending UV-C bulb chamber essentially deactivates the DNA of dust mites, viruses, mold and bacteria, quickly killing them.

UV does not kill microorganisms like chlorine does, but instead UV inactivates them. UV light at a specific wavelength of 254 nm is readily absorbed by the genetic material of microorganisms. The DNA strand is coded with a specific sequence of something called base pairs. The sequence of these base pairs codes for certain characteristics. UV light at 254 nm is readily absorbed at the point on the microorganism's DNA strand which codes for reproduction.

Yes. People with cataracts (or who've had cataract surgery), macular degeneration, and retinal dystrophies should be extra careful. Read more about these conditions in our Eye Problems and Diseases section.

Yes, the fabric provides a complete block from UV rays. Our optional items, our Solar Shield and "Weather Wrap?", will provide the same protection for the screen runs.

UV-C is part of the Ultra-violet light spectrum that is filtered out by the earth’s atmosphere. The “C” stands for the particular frequency of UV light that kills germs.

Hepatitis A virus is spread from person to person by putting something in the mouth that has been contaminated with the stool of a person with hepatitis A. This type of transmission is called "fecal-oral." HBV is spread when blood from an infected person enters the body of a person who is not infected.

Micro-organisms carry a negative charge while TiO2 coated surface carries a positive charge. This creates an "electromagnetic" attraction between the microbe and treated surface. Once contact is made, the microbe is oxidized and dies instantly.

This product is not bacteriacidal or mildewcidal. SafeNow? Bathroom cleaner used with proper cleaning techniques will remove most soap scum, hard water, and some bacteria and mildew.

Both chlorine and chloramines kill bacteria by bonding with and oxidizing the organic compounds of which bacteria are made in a free radical process.

Transitions lenses block 100% of harmful UVA and UVB rays, providing UV400 protection. In fact, Transitions lenses meet all internationally recognized standards for UV blockage including ANSI Z80.3, ISO 8980-3, EN 1836 and AS/NZS 1067. In addition, Transitions lenses were the first to receive the American Optometric Association's Seal of Acceptance for UV Absorbers and Blockers and the World Council of Optometry Global Seal of Acceptance for UV Absorbers/Blockers.

Three types of UV rays exist, including UVA, UVB and UVC. However, only UVA and UVB rays cause damage to our skin and eyes. Fortunately, UVC is absorbed by the atmosphere and never reaches the ground. Cause eye damage and are a suspect in the development of cataracts, macular degeneration and aging of the retina

Tiffen lists a wide variety of filters in the 86C size, but not a UV Protector. The closest filter available would be the Sky 1-A, a popular general use filter that will also protect your lens while absorbing about half the UV radiation, a bit more than the UV Protector. The Sky 1-A has as slight pinkish tint that adds a touch of warmth that's especially helpful when shooting in open shade or on overcast days.

far as we know - no. Only InfinityGLARE Plus can filter out the harmful ultra violet rays. All of the other waxes, polishes or sealants cannot shield your car from the harmful ultra violet rays. Waxes and polishes can even oxidize and break down under constant exposure to sun.

Antibiotics are designed to specifically target the workings of the bacterial cell. Viruses are not even similar to bacteria so the antibiotics simply don't work.

By using my hands as a way of measuring the frequency of the invading pathogens, I use the reciprocal frequency of those pathogens to neutralize them. From there, they pass out of the body harmlessly.
