Best UV air purifiers in the markets are mostly allocated for killing the germs and purifying the air on industrial sides.
Mostly in the laboratories and medical-based conditions. Even though they have got a higher level of effectiveness and better performance, UV air purifiers lead a set of common beliefs around them without having proper awareness in the community.
Therefore, from today’s Know Your Facts, we decided to talk about what are these UV air purifiers, how they operate, and the 6 best UV air purifiers on the market. Stay tuned. Read and enjoy.
What is Ultra Violet?
Ultraviolet aka UV is radiation with a lower wavelength (high energy) in the electromagnetic radiation spectrum.
Other than ultraviolet sources, UV radiation comes from the sun. With classification, this UV spectrum has been divided into three separate categories, given as UV-A, UV-B, and UV-C.
When most harmful UV-C rays are absorbed by the upper atmosphere, skin burn causing UV-B is controlled by the ozone layer.
Other than sunlight there are several kinds of artificial UV generating sources.
- UV LEDs
- UV lasers
- VUV – Vacuum ultraviolet
- Gas discharge lamps
- UV air purifiers
- ” Black lights”
- UV lamps
Harmful side of the UV light
UV light is a sort of keyword which gives to our mind that its open exposure is quite harmful. As mentioned earlier, UV-B from the sunlight harms our outside organs. For examples:
- photo-keratitis (eye condition caused by painful UV exposure)
- skin redness
- skin cancers
Other than these, the higher energy of the UV light accelerates some reactions.
For example, the reaction between volatile organic compounds and nitrogen gases (NOx) develops the ozone which is an extremely health-hazardous compound to humans.
This reaction can easily be enhanced by UV light.
Benefits side of the UV light
Even though we assume UV only represents the beneficial side too. Because on one hand there is a sort of UV requirement for the body to keep our metabolisms.
1. Fulfill our vitamin D requirement
As our school says exposure to a bit of morning sunlight increases your body’s vitamin D factor which is obviously covered by ultraviolet radiation.
This vitamin booster maintains our body’s calcium metabolism, insulin secretion, blood pressure, immunity, and cell propagation like several activities.
This obviously reduces blood pressure, diabetes, and any blood circulation systems-related health issues. So it’s the best free vitamin supplement you can have.
Other than that UV light maintains skin melanin and Serotonin levels.
2. Mood up
3. Increase body energy level
4. UV radiation therapy
5. Air purification
Other than these there are several scientific and industrial beneficial sides of ultraviolet radiation have too.
What is Air Purification by UV light?
Other than these, UV light is especially applied in the air purification process.
Unlike general air purification systems, UV air purifiers do not trap air-borne contaminants through their trapping filters.
UV air purifiers are using UV – C light-generating lamps inside the purifier. As mentioned earlier, UV-C radiation is harmful and damages living beings’ DNA.
This technique is used to remove and inactivate airborne pathogens and microorganisms like mold, bacteria, and viruses in the indoor atmosphere.
Even though we assume that purifications are just the process of switching ON there are several factors behind this:
- Contact between UV light and pathogens
- Power of the UV light
- Exposure time period
- Speed of airflow
- Material of the UV source
But the practical issue is, that UV purification systems cannot handle indoor air pollutants with a single hand.
Most UV air purifiers are combined with high-efficiency performance air (HEPA) filters too.
Who often uses UV air purification?
The main purpose of the UV air purification system is to eradicate micro-scale living pathogens. Other than using air purifiers, HAVC systems also use UV sources.
There are several kinds of industries that use UV sources in purifications. Some of them are:
- Food and beverage storage
- Medical and biological laboratories
- Water bottlers to sterilization
- Wastewater treatment plants
Normally, domestic areas do not use UV air purifiers more often. Due to the risk of health-hazardous potential (even though minimized by the latest technology).
Why UV air purifiers are not commonly used in domestic areas?
As previously mentioned harmful side of the UV light applies to air purifiers too. UV light becomes a helpful source of developing Ozone in indoor areas.
Mainly UV-C radiation has higher involvement. But portable air purifiers with UV purification system has been limited up to a certain level.
Therefore, the most recommended UV-purification locations are the industrial and medical purposes which are the places having a higher level of alive air contaminating pathogens.
