The term ultraviolet means “beyond violet” (from Latin “ultrabeyond”) and violet is the color of the shortest wavelength of visible light. Ultraviolet disinfection technology was first scientifically proven in controlled investigations over 140 years ago. Scientists discovered that if you exposed microorganisms (pathogens) to UV light, their reproduction was limited. They found that wavelengths between 200 and 300 nanometers (NM) are categorized as “germicidal” meaning this range was most effective in eliminating bacteria and viruses.
What is the UVC dose for killing or disabling the COVID-19 virus?
UVC light (energy) technically doesn’t “kill” bacteria and viruses, but rather it inhibits replication, or sterilizes it, by damaging the DNA. UVC energy is absorbed by the DNA and RNA contained in the cells, and this creates dimers or a “double bond” between adjacent nucleotides (i.e. thymine). The formation of these dimers is what inhibits the ability of the chain to replicate, which in turn leads to the death of the colony.
The effectiveness of UVC light is based on the variables of time (length of exposure), intensity of the source (how “bright” the “light energy” is), and distance (how far the source is from the target). In addition, because different pathogens require different levels of UVC to deactivate them, there is not one answer about how long it takes to kill all bacteria and viruses. The good news is bacteria, and viruses, are very susceptible to UVC energy. While some biological activity may still exist, cell replication is impossible; the microbe is no longer viable. Simply, the subject microbe cannot multiply, rendering it harmless! StAIRilizer® depends solely on direct powerful UVC energy that causes quick inactivation to rid homes, offices or enclosed rooms in larger spaces of airborne virus and bacteria's impending harm.
How long does it take to inactivate bacteria and viruses?
Because the COVID-19 virus (SARS-CoV-2) is so new, the scientific community doesn’t yet have a specific deactivation dosage. However, we know the dosage values for comparable viruses in the same SARS virus family are 10-20 mJ/cm2 using direct UVC light at a wavelength of 254nm; this dosage will achieve 99.9% disinfection (i.e., inactivation) under controlled lab conditions. In real-life, the virus is often hidden or shaded from direct UVC light, reducing UVC energy effectiveness. To compensate when treating surfaces, researchers are applying dosages of 1,000 - 3,000 mJ/cm2 to ensure 99.9% deactivation, the current CDC disinfection goal.
Influenza (Flu) and the common cold are both respiratory illnesses and they are caused by different viruses that UVC light energy and the StAIRilizer® inactivates.
What about the penetration of UVC light through “normal household” items or the StAIRilizer® box?
Prolonged, direct exposure to UVC light can cause temporary skin redness and eye irritation, but does not cause skin cancer or cataracts. If you are exposed to direct germicidal light, it can burn the top surface of your skin. If your eyes are exposed, it would be similar to a “welder’s flash”, and your eyes can feel dry or gritty. There is essentially zero penetration of UVC into any solid material that doesn’t otherwise transmit it – it would all be absorbed within a few microns. Cardboard is as good as a brick wall.
The StAIRilizer® is made of one-half inch cabinet grade plywood, overlapping air vents and box openings prevent direct UVC light from exiting the box. In short, designed in such a way that it protects people, pets and plants from ever being exposed to the harmful effects of UVC light.
What are the differences and similarities of virus and bacteria?
Bacteria and viruses are microbes (germs) which are very different to each other in structure and function. Despite the important structural and cultural differences, both bacteria and viruses can cause disease in similar ways: they invade and multiply within the host by evading the immune system.
Viruses are smaller than bacteria. In fact, the largest virus is smaller than the smallest bacterium. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can’t survive without a host. They can only reproduce by attaching themselves to cells. In most cases, they reprogram the cells to make new viruses until the cells burst and die. In other cases, they turn normal cells into malignant or cancerous cells.
How does the StAIRilier dose air throughout my home?
HVAC systems and ceiling fans that keep air either cooled or warmed in your home is how the StAIRilizer doses air throughout. Most of the rooms in your home are the same temperature and that is proof that air is circulating. The StAIRilizer system uses the systems that are already in place to disinfect the air.
Unfortunately this same air circulation results in people being infected while indoor, enclosed spaces even with social distancing procedures.
The fan in the StAIRilizer is rated for 23 cubic feet of air per minute. In a ten hour period of running time it will move the air in a 1,725 square foot home with an eight foot ceiling one time.
What makes the StAIRilizer different than other UVC devices?
StAIRilizer is a discreet enclosed box designed to let people and pets stay in the area while it quietly operates. This design also keeps UVC light from harming furniture and plants that are in the area. StAIRilizer damages airborne virus and bacteria that are more likely to be inhaled and infect people.
StAIRilizer is plugged into a common grounded outlet in you home and set up by you in less than fifteen minutes. No permanent expensive installation costs and can be moved to different rooms in your home.
Devises that use direct light to disinfect surfaces in a room are unable to be effective in the shadows or behind objects in the room. The distance from the light (energy) makes even objects that are in direct light to far from the light to be disinfected without hours of exposure.
StAIRilizer's multiple safety devices eliminate someone being accidentally exposed to the disinfecting procedure. Devises that are left running in an empty room can't make this claim.
What colors are available?
StAIRilizer has four color options that are pure white, classic silver (gray), limousine leather (black) and espresso bean (brown). We use Behr Marquee one-coat enamel paint in an eggshell finish from Home Depot.
If you would like a different color, we can sell you the StAIRilizer unfinished.
Is the StAIRilizer box noisy?
The fan in the StAIRilizer box is designed for high-end audio-video equipment and has a noise level of 28 dBA and can be ran continuously for 67,000 hours (7.5 years).
What UVC bulb is used in the StAIRilizer?
The UVC bulb used in the StAIRilizer is stated to have a life cycle of 8,000 hours, if you ran the StAIRilizer for eleven hours per day for two years the bulb would have 8,030 hours of use. We recommend replacing the bulb every two years no matter how many hours it has operated. We do sell replacement bulbs on our site at a reduced cost to StAIRilizer owners.
The UVC bulb used in the StAIRilizer® is 254 nanometers and does not produce Ozone.
The dosage chamber was designed around the power and size of the UVC light bulb and the volume of air being dosed, those factors make the box a rectangle style.
