Everything about UV care technology

UV care technology has recently gotten popular among consumers. If you or someone in your household suffers from respiratory problems, a high-quality UV filtering system is a must for your HVAC system.

UV filtering systems are capable to deactivate a wide range of viruses, bacteria, and other dangerous germs such as mold. This not only maintains the air in your house free of hazardous airborne particles but it may also help your HVAC system last longer.

What is UV care technology?

Ultraviolet light, often known as black light, exists outside of the visible light spectrum and can only emit light when reflected off other colored surfaces. Shining a UV light on hues like orange or white, for example, will give them a lovely shine. The sun produces UVA photons which account for up to 95% of UV radiation reaching the earth’s surface. UVA radiation is hazardous to humans, causing skin damage and contributing to wrinkles. UV radiation may also be used to fight against bacteria and viruses such as COVID-19. When pathogens are exposed to UV light, they are disintegrated and become harmless moisture.

The location of the UV lamps to destroy mold and germs will be determined by the size of the HVAC system. The germicidal UV light bulb will be positioned within the evaporator coils in most residents. This is where microorganisms thrive and cosmic combat will take place. The germs that were traveling through your air ducts, will be blasted apart by the powerful UV light at this moment.

How does UV care technology work?

UV lamps, unlike other forms of particle-catching air filtration systems, destroy the cell structure of microorganisms, rendering them inactive and preventing them from replicating. While an air filter may trap germs and keeps them from moving in your home’s air, UV lamps sterilize microorganisms’ DNA and render them inert.

UV light purifying systems are divided into two categories:

  • Cleaning the coils: Near your evaporator coil, UV light purifiers are mounted. Because your evaporator coil is the element of your AC system that dehumidifies your house, this is a great spot for UV light. Your evaporator coil is a wonderful growing habitat for organisms like mold since it has condensate on or around it all of the time. The UV light shining on your evaporator coil can help keep germs, mildew, and viruses at bay.
  • Cleaning the air: Cleaning the air UV lamps are often installed at the opening of your return ducting to clean the air before it is cooled by your air conditioning system.

UV lamps might be installed in one or both of these areas, depending on your system or the type of UV purification system that you install. Our recommendation is to consult with an HVAC specialist to evaluate which solution is the best for your house.

UV lights for HVAC systems are made to emit a certain wavelength of light 254 nanometers that is absorbed by microbial DNA. The organisms are unable to synthesize the proteins. They are required after being exposed to UV radiation. Although the UV light does not destroy the bacteria right away, it disables their potential to cause damage and significantly reduces their lifespan.

UV radiation, when correctly applied, is quite effective in killing nearly all of these hazardous chemicals. Installing the UV HVAC system in your condensing unit, also known as the air handler, is a cost-effective way to clean all of the air that flows through the system.

Difference between dual defender & UV care technology

Dual defender technology has a combination of an ionizer and antiviral filter. The three-layer antiviral filter contains varieties of natural and synthetic ingredients that can prevent the virus, bacteria, and odor particles as well as remove fine particles up to 0.3 microns. This filter has another layer of antioxidants that can remove free radicals and other harmful elements from the air and provide fresh air to your room.

On the other hand, UV care technology is a radiation approach for neutralizing bacteria that uses a specific wavelength of ultraviolet light. UV-C light is germicidal which means it disrupts the capacity of microorganisms like bacteria, viruses, and other pathogens to reproduce and deactivates their DNA. Germicidal irradiation, UVGI, and UV-C radiation are all terminology that is used to describe UV-C light technology. All of these words relate to the same thing. Ultraviolet-c light stops infections from spreading.

Why UV care technology is demandable in Bangladesh

UV care technology is safe and has several additional advantages. For that reason, UV care technology is demandable in Bangladesh.

  • Keeping your evaporator coils clean easy is one of these advantages. The grille covers the coils is frequently blocked with dust and mold, causing your air-conditioning system to underperform. If it is not cleaned, as a result, your HVAC system’s efficiency will be poorer and it will have to work more and consume more energy. This incurs to increase in power expenditures, particularly during the summer when house temperatures are at their maximum. Easy cleaning makes the total hefty process easy.
  • UV light for air conditioners improves efficiency and can help you save money on your energy costs. When your cooling system consumes less energy, it not only saves you money but also benefits the environment.
  • Another advantage is that you won’t have to use harsh chemicals to clean your evaporator coils. When the grille and coils get filthy, a foaming agent is used to clean them. Many toxic compounds, such as diethylene glycol monomethyl ether, 2-butoxyethanol, and liquefied petroleum gas are included in some of these cleaning solutions. Avoiding such toxins would be extremely advantageous to the home’s occupants. Nobody knows how long it takes for these compounds to leave the cooling system completely.
  • The UV light will act as an air purifier for the air in your house, ensuring that your system remains clean and efficient for many years.


You may be asking whether UV care technology is worth it for your house now that you understand how they function, and the benefits of installing UV care technology. If you or someone in your household suffers from respiratory problems, a high-quality UV filtering system for your HVAC system is a must. Because it combines UV radiation with a high-MERV filter, the UV filtering system differs from the UV purifying system.

UV lights inactivate a wide range of bacteria, viruses, and fungi and the MERV filter captures the sterilized germs in a UV filtering system. If you have respiratory problems, the UV filtering system that sterilizes and releases fresh air that makes it well worth of money.
