UV Light Air Disinfectant - Inactivate All the Airborne Pathogens and Inhale Healthily

Published on : 2nd January, 2021


Ultraviolet (UV) light has been used historically to clean water, surfaces, and the air. You may wonder if this device works well against the airborne microbes or in any way helps increase the home's air quality. Here’s everything you need to know about UV light for air purification.


What are UV light Air Purifiers?

UV air purifiers utilize the power of short-wave ultraviolet light (UV-C light). The airborne contaminants and microorganisms such as mold, bacteria, and viruses can be inactivated using the power of UV-C light. The air purifier has the same overall aim: to reduce indoor air contaminants. The technology used is known as UV germicidal irradiation or UVGI air purifiers.
UV-C wavelength is responsible for the main disinfectant activity of UV-C air purification systems. UV energy destroys the molecular bond of the RNA/DNA that absorbs it, making the microbes incapable of replicating .

What are the different forms of light?

Light is made up of photons. As the light travels, it vibrates back and forth to trace a wave in space. The faster and quicker they vibrate, the shorter would be the distance traversed between each wave. Depending on the overall molecular makeup there are different materials in the world that reflect and absorb the different wavelengths of light.

  • Visible light has a wavelength of between 400-700 nanometers, which is the range that affects your eyes' light receptors.

  • Infrared light is longer, which you can sense as heat (700 to 1M nanometers).

    • Ultraviolet, at 100 to 400 nanometers, which you can’t detect or see, is shorter than visible light. There are 3 sections for Ultraviolet light :
    • UV-A radiation: 315-400 nanometers of photons that vibrate slightly more rapidly than visible light.
    • UV-B light: 280-315 nanometers, with photons vibrating even more rapidly.
    • UV-C light: 100-280, with the fastest vibrating and most energy-carrying photons.

How UV light for Air Purification uses UV-C Light?

UV-C light is responsible for the main disinfectant activity of UV-C air purification systems. Microorganisms around the UV lamp are bombarded by ultraviolet light and the UVC damages the DNA/ RNA of microbes.
Since bacteria are only one cell, they rely on their DNA in order to survive. This is the concept behind air purifiers for UV illumination. If the DNA of a bacterial cell is sufficiently harmed, it causes a process to self-destruct, rendering it harmless. This is how UV-C light for the air purification system works.

How do Ferroplast UV Air Purifiers Clean the Air?

Ferroplast UV-C Air Disinfectants intakes the air with the help of the fan installed at the bottom. The air passes through the chamber containing powerful UV lights. The device is designed to optimize the fan speed such that the air inside the chamber is exposed to sufficient dosage of UV-C. The UV-C destroys the microbes and clean air is then released from the top. The polycarbonate coating ensures that the UVC remains inside the chamber, making it safe to be used in human presence.

How is the efficacy of the Ferroplast UV-C device tested ?

Multiple tests have been conducted by NABL accredited labs as well as labs approved by the Ministry of Health of Russian Federation. The tests showed that the device is capable of destroying 99.99% bacteria & viruses in air in minutes.
