    Air quality and it's bacteria can be a serious concern. If you are one of those who suffer from allergies or asthma respiratory conditions you know that clean air is the most important. Not being able to breathe is truly scary. Germicidal UV can make the difference. Environmental Protection Agency (EPA) frequently reported that indoor air can be more polluted than the air outside. Whether you have a health condition or not, you could definitely benefit from breathing cleaner air with UV purifiers for your home.   How do these devices work? Germicidal UV cleaners use filters and Ultraviolet light to purify the air inside your home. You might be surprised but microscopic allergens like dust, mold, mildew, pet dander and pollen live in the same indoor area as you do. Air pollutants come from any source, furniture, rugs, carpets, toys, pets you name it and even the household cleaning product.   Maybe you are not one who suffers from these health conditions...

  Have you ever heard that ultraviolet (UV) light can be a biocide for living things? You can find the answer within the following info.   Starting with the history, the study on UV rays and its biological effects began around 1888 when Neils Ryborg Finsen decided to analyze this matter. He proposed that UV rays could kill bacteria. This discovery motivated other inventors to perform further analysis on this subject, including the mechanism of UV rays on microorganisms and applications in biology, medical sterilization, also air and water treatment.   UV (ultraviolet) light is part of electromagnetic spectrum which ranges from gamma rays to radio waves. The short wavelength and high frequency gamma rays are more energetic than radio waves which have long wavelength and low frequency. Therefore radio waves do not give bad effects no matter how long you are exposed to it. On the other hand, the short waves from gamma rays will be dangerous, even deadly.   Of the electr...

  It has been known more than 100 years ago that Ultraviolet (UV) light has a germicidal effect. The natural source of UV light is the sun. It emits about 10% of its energy in the UV region. However, since it is mostly blocked by the earth's atmosphere it has no germicidal effect in our immediate environment, like our home's indoor air quality or our water systems. Ultraviolet is a spectrum of light just beyond the visible range. UV light is divided into four ranges of wavelengths: (1) Vacuum UV from 100 to 200 nanometers, (2) UV-C from 200 to 280 nanometers, (3) UV-B from 280 to 315 nanometers, and (4) UV-A from 315 to 400 nanometers. The UV-C spectrum (200 to 280 nanometers) is the most lethal wavelength for microorganisms, because it disrupts the chemical bonds between the atoms which, in biological terms, results in a "dead" microorganism. This range of wavelengths is also known as the Germicidal Spectrum. The germicidal spectrum is used to destroy bac...

  COVID-19 (Coronavirus Disease 2019) is the disease caused by the novel coronavirus, SARS-CoV-2, which is the cause of a viral outbreak that led to a devastating global pandemic. Public health systems and economies worldwide have been ravaged by this virus and many people are asking the question, “Does UV light kill Covid?”. As of December 31, 2021, the pandemic is experiencing a surge with the new Omicron variant and a total death toll of 5,439,895 globally, with more than 825,816 deaths in the United States.   We put together a compilation of several studies showing the effectiveness of UV light for COVID, although according to the Food and Drug Administration, FDA, as of February 2021 there is still a limited amount of published data on the required dose, wavelength, and duration of UV light necessary to kill the SARS-CoV-2 virus that causes COVID-19.   Types of UVC Lamps Effective in Killing Covid   Ultraviolet (UV) light is a type of UV radiation f...

  Start Breathing Easier in Your Home There are numerouskinds of UV lights on the bazaar today, especially with the current concerns about living healthy and germ-free. However, it's hard to know which ones you can confidence with your family's well-being and which ones are fake and ineffective. What are UV lights? Ultraviolet (UV) light is a constituent of the electromagnetic spectrum that decreases in the region between visible light and X-Rays. UV light includes the wavelength range of 100 nm to 400 nm and can be additional subdivided and categorized into four separate regions: 100 nm to 200 nm: Far UV or vacuum UV (these wavelengths only propagate in a vacuum) 200 nm to 280 nm: UVC – valuable for disinfection and sensing 280 nm to 315 nm: UVB – valuable for curing, tanning and medical applications 315 nm to 400 nm: UVA (or “near UV”) – valuable for printing, curing, lithography, sensing and medical applications How does UVC disinfection w...
