aircon sanitizer

We're all too familiar with Singapore's hot and humid climate; that's why aircon units are the most important and the biggest electric consumer at home.

With summer being the only season all year round, optimal performance from your aircon unit is a must-have to provide you with the comfort you desire.

But did you also know that apart from giving fresh and conditioned air, your aircon unit can also help you to be safer, especially with the threat of the pandemic?

Yes, you read that right!

Air sanitising features used to be mostly available only in portable room air cleaners, but with the threat of Covid-19 everywhere, it has become increasingly popular. As a result, it is featured in many newer AC systems.

But what if you want an air sanitiser upgrade without buying a whole new aircon?

Well, keep reading to find out how that's possible! In a hurry? 338 Aircon would be the best AC installation company in Singapore that you can engage for this aircon upgrade.

Firstly, let's explore why it matters:

Air quality, indoors and outdoors, is crucial to our overall health and well-being.

The amount of indoor and outdoor air pollution we breathe directly impacts our respiratory system and can have long-term effects on our physical and mental health.

Poor indoor air quality directly impacts our daily lives as we spend a significant amount of time indoors, whether at home or in the workplace.

Indoor pollutants, such as volatile organic compounds (VOCs), formaldehyde, and radon, can also be emitted from building materials, cleaning products, and furniture.

Inadequate ventilation allows these pollutants to accumulate, increasing the risk of respiratory problems, allergies, and other health issues.

Additionally, mould and dust mites thrive in damp and poorly ventilated environments, exacerbating respiratory conditions like asthma.

On the other hand, outdoor air quality is determined by factors such as vehicle emissions, industrial activities, and natural sources like pollen and dust.

Pollutants such as particulate matter, nitrogen dioxide, ozone, and sulfur dioxide can be present in high concentrations in outdoor air, especially in urban areas.

The worst part is that inefficient ventilation systems can also lead to polluted outdoor air coming indoors, increasing the risk of developing chronic conditions such as lung cancer, stroke, and respiratory infections.

Are air sanitizers and purifiers the same?

First, let's get to know the difference between air purifiers and air sanitisers since they have many similarities:

  • reduce indoor air pollutants

  • reduce any symptoms of allergies

  • reduce complications from asthmatic conditions

  • lessen respiratory issues

  • improve sleep quality

Ultimately, the difference lies in the type of air pollutants removed and how they are removed.

Air sanitisers excel at eradicating viruses, bacteria, and mould from the air through UV light sanitizing systems.

On the other hand, air purifiers employ sophisticated air filtration systems to minimize dust and pollen particles indoors effectively.

When addressing concerns related to illnesses, air sanitisers hold the advantage.

Adhering to the adage "prevention is better than cure," UV sanitization systems treat indoor air, effectively eliminating a wide range of harmful substances, allergens, and even unpleasant odours caused by pets.

How can air conditioning systems act as air sanitisers?

Air conditioning units have become more than just devices for cooling or heating indoor spaces.

With the growing emphasis on maintaining a healthy environment, many modern air conditioning systems are equipped with features that actively make the air cleaner.

These advanced functionalities aim to improve indoor and outdoor air intake and quality by reducing contaminants and creating a safer and more comfortable living or working environment.

However, if you want to upgrade it with even better features, like a UV aircon sanitizer, it's best to leave it to the professionals!

It takes approximately 5 minutes to install a UV sanitization system that includes UV LED and photocatalyst, but many more considerations come behind it.

How do UV air sanitisers improve indoor air quality?

UV-led air sanitisers combine a forced-air system with UV light and a secondary filter, typically a HEPA filter, to effectively clean the air.

The device draws ambient indoor air into the unit, which is then directed through a chamber containing UV-C light bulbs.

Furthermore, you won't have to worry about the negative effects of UV rays with UV sanitisers.

Although the emitted light falls within the visible spectrum, you won't see it due to the casing surrounding the bulbs. Additionally, UV-C lights used in germicidal purifiers operate silently and are typically odourless.

How effective is UV aircon sanitizer?

UV LED technology can potentially deactivate harmful microbes, but its effectiveness within portable air sanitiser units warrants further examination.

These compact devices are commonly marketed as capable of reducing dust mites and mould allergens, but the actual disinfection power of UV LED relies on several crucial factors:

Contact with UV LED light

The effectiveness of UV LED in disinfecting the outdoor air enters part depends on whether the pollutants come into direct contact with the emitted light.

If the outdoor air flows or circulates in a way that prevents particles from reaching the UV LED source, the disinfection process may be compromised.

Cooling effect of airflow

The airflow within a portable air sanitiser unit can cool down the UV LED light.

This cooling effect might diminish the potency of the emitted UV rays, potentially reducing their ability to deactivate microbes effectively.

Material of the UV LED bulb:

The material composition of the UV LED bulb used in the portable air sanitiser unit can influence its disinfection capabilities.

Certain materials may emit UV light at wavelengths less effective in tackling indoor air pollution, while others may generate more powerful UV rays.

High dosage of UV light:

UV LED disinfection often requires a sufficiently high light dosage to neutralise air microbes effectively.

Achieving the appropriate dosage within the confined space of a portable air sanitiser unit is crucial for optimal disinfection performance.

Duration of exposure:

The duration for which pollutants are exposed to the UV LED light also affects its effectiveness.

If the contact time is insufficient, the disinfection process may be inadequate, allowing some microbes to remain active.

Different types of air sanitization systems in air conditioning units

Photocatalyst: Titanium Dioxide (TiO2)


In the context of sanitization or the elimination of viruses, a remarkable process occurs, employing a method known as photocatalysis.

This technique harnesses the unique properties of titanium dioxide (TiO2). This material not only absorbs ultraviolet (UV) light but also amplifies its energy levels, effectively breaking down harmful substances.

Through the ingenious utilization of photocatalysis, UV light interacts with titanium dioxide, empowering it to neutralize and disintegrate a wide array of hazardous particles, promoting a cleaner and healthier environment.

The application of TiO2 as a photocatalyst extends beyond air sanitization and finds widespread use in various domains due to its exceptional photoactivity, remarkable stability, affordability, and, perhaps most importantly, its safety for both humans and the environment:

  • water purification

  • self-cleaning surfaces

  • renewable energy production

The captivating characteristic of titanium dioxide lies in its extraordinary durability, allowing it to persist for decades, ensuring that TiO2 continues to provide its sanitizing benefits throughout the entire lifespan of your AC.

Ultraviolet-A (UVA) and Ultraviolet-C (UVC) Radiation

UVA UVC Radiation

To improve indoor air quality, a UV sanitization system incorporates a comprehensive approach by harnessing the power of UVA and UVC radiation.

By utilizing both longer-wavelength UVA and shorter-wavelength UVC, this system effectively targets and eliminates harmful substances and pollutants, with a particular emphasis on combatting viruses present in the indoor air.

The system employs multiple UV LED strips strategically placed within the air conditioning unit to achieve optimal air sanitisation.

As the air circulates through the unit, it passes through these UV LED strips, where the combined UVA and UVC radiation work in tandem to sanitize and purify the air.

This thorough air treatment eliminates potentially harmful particles carrying indoor air pollutants and significantly improves the overall air quality, leading to a healthier and more comfortable indoor environment.

Another notable advantage of our UV sanitization system is the longevity of the LED components.

With a lifespan of approximately 10,000 hours, equivalent to around three and a half years of operation at 8 hours per day, the UV LED strips provide sustained and reliable air sanitization without frequent replacements.

This durability ensures consistent protection against common airborne viruses, such as hemolytic streptococcus (causes cough and pneumonia), salmonella (leads to acute gastroenteritis), and even formaldehyde (associated with respiratory diseases and cancer).

Why should you invest in a UV air sanitation upgrade?

Maintaining clean and healthy indoor air has gained significant attention in recent years.

With the increasing concern over harmful substances and allergens from indoor pollutants, it has become crucial for individuals to invest in air sanitisers.

By sanitizing indoor air, these devices effectively remove viruses and other contaminants and generate fresh air, ensuring a healthier and more breathable environment for residents.

Such a priority in protecting indoor air quality can significantly contribute to overall well-being.
