There are normal air purifiers in the market, and then there are certain cleaners accompanied by special UV light technology. One distinct feature that makes these air purifiers so unique and worth buying is performing much better than the normal ones. The UV light installed in these purifiers helps kill harmful particles and pathogens in your home more efficiently.

UV light, or Ultra-violet light, is a part of the electromagnetic spectrum, consisting of several wavelengths of different variations such as light, x-rays, and radio waves. They are arranged as per their frequency. The UV rays are invisible to the naked eyes.

In layman’s terms, air purifiers with UV lights can help disinfect indoor environments, thus improving your family members’ health.

Types of UV Light Used in Air Purifiers

UV radiation is a kind of non-ionizing radiation that can be found in the sun’s rays and other artificial sources. Generally, there are three types or sub-categories of UV lights. These subcategories help provide distinctive features and specialties that make each one of them unique and differentiated. The three types of UV lights include:

1. UV-A

This is the most commonly used and known type of UltraViolet rays, which accounts for 95% of the sun’s radiation reaching the earth. This long-wave light is often used in tanning beds to penetrate through the skin’s second layer. When exposed to human skin for a long time, the UVA light can cause aging and wrinkling, and sunburns.

2. UV-B

When you walk out of your home during summers and find your skin turned red, this UV ray is responsible for that. Sunburns are also caused by UV-B rays when human skin is exposed to the sun’s rays for a long time. The UV-B rays have also been linked to some skin cancers. They also have the potential to damage the skin’s DNA.

3. UV-C

This is the most dangerous UV ray which is responsible for killing organisms and skin cells. But this type of ray never reaches the earth thanks to the ozone layer, which blocks the sun’s radiation. However, UV-C rays can be made artificially on earth. That is why many air purifiers have it in their system. They help purify the air as most organisms cannot survive after getting exposed to these rays.

How Do the UV Light Air Purifiers Work?

The efficiency and performance of an air purifier with UV light depends majorly on the following three factors:

  • UV-C Light Exposure Time: The total time length of exposure is a significant factor determining how many pathogens are being inactivated during filtration. In half a second, sufficient damage is caused to kill all the contaminants coming in contact with the UV lights.
  • Intensity and Wavelength: Apart from exposure time, the intensity and wavelength contribute to inactivate or killing the pathogens ultimately. The optimal wavelength for UVGI is 254 nanometers.
  • Proximity to the light: The pathogens or pollutants should stay close to the UV light if they do not come in direct contact with the light. This also disintegrates them.

A filter with UV light technology sucks in the air present in the room and passes it through a fine filter present inside. The air goes through an internal chamber where the UV light cleans the air of any remaining harmful pollutant, micro-organism, dust, pollen, etc.

How Are They Different from Normal Purifiers?

Air purifiers for home that come with UV light technology are not very different from the normal ones. The UV light is just another protective shield or filtration weapon used to eliminate the remaining microorganisms, pollen, pet dander, or pollutants left even after the air’s filtration. Even the tiniest microorganism or pollutant can be destroyed using the UV light, making the air healthier and safer.

Why Should You Buy Air Purifiers with UV Lights?

Air purifiers with UV lights are considered very effective in removing harmful particles and pollutants in the air, which even normal filters fail to remove. Since these filters use rays to kill and eliminate such pollutants, they leave very few or almost no harmful residue in the filtered air. Here are some of the benefits of air purifiers with UV lights:

  3. Complete cleaning: When you perform dusting or cleaning, some particles of the germs, dust, or microorganisms stay suspended in the air and later get deposited on the floor, hence beating the whole purpose of cleaning. A UV light air purifier helps you get rid of these pollutants as well.
  4. Removes mold spores: Humidity in the room causes molds to form in the area. These molds are invisible to the naked eye and can cause triggers to allergies and asthma. Air purifiers with UV are effective in eliminating these mold spores from the room.
