FAQs

Ultraviolet light is a type of electromagnetic radiation; Electromagnetic radiation comes from the sun and is transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic (EM) spectrum.

There are three main types of UV rays they are UVA, UVB, and UV-C.

UV-C light is GERMICIDAL - it deactivates the DNA of Bacteria, Viruses, Mold and other pathogens and thus destroys their ability to multiply and cause disease.

Prolonged, direct exposure to UV-C light can cause temporary skin redness and eye irritation, IVAS Facilities Services Ultraviolet Systems are designed with safety in mind and, when properly installed by a professional contractor, do not allow exposure to ultraviolet irradiation and allow for safe operation and maintenance. 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. At no time do germicidal lamps cause any permanent damage.

No, our machines are equipped with motion sensors that will turn off the machine immediately if any motion is detected.

Yes, your pets will need to stay with you during the UV-C process.
Yes -germicidal UV-C lamps kill up to 99.9% of most viruses, airborne bacteria and mold spores.
In UV-C sterilization applications, direct exposure to 254nm UV-Cradiation, given appropriate exposure time, will inactivate the DNA and RNA of microorganisms (such as bacteria, viruses, mold spores, yeast, and protozoa), rendering them "sterile" (unable to reproduce), which, in biological terms, results in a "dead" microorganism.
Yes. Germicidal UV-C lamps will kill up to 99.9% of mold and help prevent future mold growth.
The exposure of germicidal Ultraviolet is the product of time and intensity. High intensities for a short period and low intensities for a long period are fundamentally equal in lethal action on bacteria. The inverse square law applies to germicidal ultraviolet as it does to light the killing power decreases as the distance from the lamps increases. The average bacterium will be killed in ten seconds at a distance of six inches from the lamp. {see our spec sheet for UV-C Irradiation Dosage Table}. An acceptable kill rate is determined by the total amount of UV-Cenergy a microorganism "sees." This is a "dosage." Dosage is a product of the intensity of UV-C radiation (expressed in micro-watts per square centimeter) and exposure time to that radiation. You can find the necessary dosage for most common mold spores in the following table. Mold spores are generally much more difficult to kill than microorganisms and viruses and, thus, require a much higher dosage of ultraviolet light. The values shown under the percentage kill are in micro-watts per square centimeter of UV-Cenergy.
No. Germicidal UV-C sterilizes only what it comes in contact with.
Because UV-C rays have the shortest wavelength, and therefore highest energy, they are capable of killing bacteria and viruses, also called pathogens. UV-C light has a wavelength of between 200 and 400 nanometers (nm}. It is highly effective at decontamination because it destroys the molecular bonds that hold together the DNA of viruses and bacteria, including "superbugs," which have developed a stronger resistance to antibiotics. Specifically, UV-C light cause's damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA the formation of such bonds prevents the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.
It all depends on the size on the room & the distance from the surface to the UV-C light source. However, unlike liquid cleaning agents, no contact with the surface or device is required when sanitizing with UV-C light. It does not leave a residue or cause discoloration after the process. There is no downtime after sterilization - the area or equipment can be used immediately after disinfection. It is important to consider that the longer the surface, area or device is treated by the UV light, the higher the disinfection rate. This is because more thymine dimers are generated in the DNA of the virus. Furthermore, the UV light should be intense to ensure thorough disinfection. The effectiveness of the light will decrease, as the distance from the light is increased.
UV light has been tested as an effective solution against a myriad of viruses. According to an article published in Journal of Virological Methods, SARS caused by the corona virus (SARS-CoV) is eliminated through exposure to UV light in the 254 nm range. UV treatment has also been found to kill MERS or MERS-CoV, a type of corona virus that emerged in 2012. In a study published in the US National Institutes of Health's National Library of Medicine(NIH/NLM), UV-C light deactivated MERS-CoV within 5-10 minutes of exposure.When it comes to the latest outbreak of COVID-19, UV light has been confirmed to be effective in eliminating the virus by Juan Leon, an environmental health scientist at Emory University, and Dr. Lena Ciric, an associate professor at University College London. UV-C treatment is already proven to work on previous strains of the corona virus, i.e. SARS-CoV and MERS-CoV, as mentioned above. Therefore, it makes sense for the light to be used against COVID-19.

We have quantifiable Dosimeter Cards that are calibrated for the disinfection of the Bacteria MRSA & C-diff. Bacteria require significantly higher dosage of UV-C than Virus & therefor we know that if we achieved a level of disinfection that will inactivate MRSA & C-diff we know that we have also inactivated Corona Virus. The Dosimeter Cards are used with every treatment & are scanned & emailed to the customer after every treatment.
In order to achieve Hospital-Grade Disinfection, a daily multi-barrier approach must be implemented. Remember that there is no "Magic Bullet" when it comes to disinfecting. Different surfaces require different treatments. Examples of treatments include electrostatic chemical disinfection and UV-C disinfection.
