Air purifiers with UV lights have emerged as a promising solution to sanitize the COVID-19 corona virus. These are also known as ‘sterilization lamps’ and they are certainly able to kill 99.9% of viruses. Usually, ultraviolet abbreviated as UV light has been widely used to disinfect water, different surfaces, and the air for ages. If you are looking for the Whole Home Duct Air Purifier in USA, you can be assured of the fact that this specific technology works against airborne microbes and it certainly improves the air quality of your home and office.
What are UV light air purifiers?
UV air purifiers are designated to use short-wave ultraviolet light also known as UV-C light to nullify the effect of airborne pathogens and microorganisms such as mold, bacteria, and viruses. As, it is quite evident that the major goal of all air purifiers is to decrease the number of air pollutants in home or in office. The specific technology is also attributed to as UV germicidal irradiation, or UVGI air purifiers. Hence, it differs greatly from other air purifier technologies that usually contain UV light technology, but never use it directly against air pollutants. You can easily look for the best HVAC duct mounted UV light air purifiers online and keep your premises free from bacteria and viruses.
Different forms of light
Light consists of small particles known as photons. As they travel, they vibrate backwards and forward, and track a wave in space. Usually depending on their molecular makeup, varied materials in the world display and absorb varied wavelengths of light:
- Visible light has a wavelength usually between 400-700 nm long.
- Infrared light is longer comparatively usually between 700 to 1M nm.
- The wavelength of Ultraviolet is shorter than visible light usually at 100 to 400 nm.
Ultraviolet light: UV-A, UV-B and UV-C
Ultraviolet light is split into majorly three sections:
- UV-A light: 315–400 nm
- UV-B light: 280–315 nm
- UV-C light: 100–280 nm
The UV-C light air purifiers are designated to use UV lamps that can likely amend the DNA of microorganisms and sanitize or destroy them. The light may be blueish or may not be seen by naked eyes and it usually depends on the material of the emitter such as phosphor or quartz.
How effective are UV air purifiers?
The effectiveness of UV-C light in sanitizing the air depends on a number of factors that generally include:
- If the pollutants come into direct contact with the UV light
- If the light is constrained by the cooling effect of airflow
- The material used in making of the bulb emitting UV light
- The amount of light needed
- How long the pollutant is made public to the light
UV air purifiers vs. microorganisms
If designed properly, the UV filtration process can certainly kill a number of bacteria and mold and usually offer a small decrement in viruses, but little decrement in bacterial and mold spores. Usually, bacterial and mold spores are contrary to UV radiation and need a high dosage of UV light.
UV air purifiers vs. allergens
UV purification never mitigates allergens, chemical fumes, dust, pet dander, cigarette smoke, or mold completely from the air. Hazardous gases and a number of solid particles are generally invincible to UV radiation.
UV air purifiers vs. VOCs
A number of harmful pollutants are guileless by UV-C light. UV light can never destroy buoyant organic compounds, or VOCs generally found in household products, starting from paint and embellish to cleaning, sanitizing, and cosmetic solutions.
