UV Air Purifiers – How Does Ultraviolet Work?

We often think of air purification as an amenity. Unfortunately, the increasing emissions and urbanisation of this planet has result in an unprecedented compromise of air quality. More people are suffering from autoimmune deficiencies that were almost unheard of prior to Europe’s Industrial Revolution.

Air purifiers are by no means a breakthrough invention. They clean the air by sucking it into its vents, through several layers of filters that catch the pollutants and allergens, and then blowing it back out into the room. They rely on filters and airflow to help clean the indoor air.

But a newer, more advanced air purification technology is promising even greater air purification, allowing homeowners to enjoy legitimate automated sanitation for the first time.

We’re referring to UV air purifiers combined with TiO2 filters – a new technology that employ a new kind of air filtration system entirely. In fact, these systems no longer rely on filters or airflow whatsoever. The devices employ oxidisation technology; deploying blankets of oxide particles that don’t only cleanse the air but also surrounding surfaces in the room.

What is UV light?

UV is short form for Ultra-violet light radiation. This is defined by light that is between 200 nanometers (nm) and 400nm. These distances are so small that they are invisible to the naked eye.

The three different types of UV light are simply determined by the distances of these bands: UV-A, UV-B, and UV-C. Also classified as long-wave UV light [between 315nm and 400nm], UVA is sometimes referred to as “black light”.

Germicidal UV light [200nm to 280nm] should be the only kind of UV light that matters to people who are looking to rid their homes of harmful air contaminants. This is provided, they ensure they take the government’s recommended measures to prevent sun damage caused by UVB rays [280nm to 315nm].It is officially classified as UV-C.. Believe it or not, germicidal lamps that employ such UV bands are the most effective means to control these microbial outbreaks.

What does UV light do?

By using a UV light solution, consumers can substantially reduce indoor pollutants that stick and breed within various HVAC units and residential installments. When it comes to getting rid of moulds, yeast colonies, harmful bacterial cultures, and viruses; UV TiO2 Purifiers are in a class of their own.

While odours are a somewhat accurate indicator of air cleanliness, they are only the tip of the iceberg. Most microbial pollution cannot be viewed by the naked eye and a microscope is required to make out these pathogens, bacteria and mould culture. Even if you get your home professionally inspected, it could still be home to thousands of these microorganisms.

UV technology inside an air purifier ensures that even the air filters inside the unit will be rid of any bacteria and viruses, promising that only totally clean and healthy air is introduced back into your home.

How does it work?

UV-C destroys air pollution similarly to how UV-B rays causes sun burn in humans. However, they do so on a much smaller scale and thus, are proven to be safe for use in residential and office environments.
The light is strong enough to penetrate the cell walls of the organism. This disturbance results in damage of the organism’s DNA. As such, its activity is neutralised and in some cases, becomes sterilised. A microbe’s susceptibility to break down correlates with an increase to higher expose UV-C light rays.

Do I still need an air filter?

Before you rush an install UV TiO2 lights it’s important to ensure that you install the full system. This entails that you have a conventional dust filter already installed. By filtering out the major dust particles first, the UV TiO2 will not only be kept safe but will be optimally efficient. This is the most economic solution for protecting your home from indoor pollution.

Could you benefit from healthier air?

Everyone suffers from the adverse effects of air pollution. The degree to which they’re affected depends on variables such as immune system genetics, allergies, autoimmune deficiencies, and age. Specifically, children and elders are the most sensitive to poor indoor air quality.

While it may not be on the radar to the same extent as climate change or serious air pollution, poor indoor air quality is very much a universal problem, especially as we spend 90% of our time indoors.

People with autoimmune deficiencies allergies, and asthma benefit the most from proper air filtration initiatives. We are humbled to be able to provide real air filtration solutions and look forward to vastly improving the quality of life for families with young children and senior citizens.
