The advent of the COVID-19 pandemic has presented a new and formidable challenge to the air conditioning sector as a whole. Since the novel coronavirus is particularly contagious and has been seen to spread even through air conditioning ducts and air flow, sitting in an air conditioned space along with other people - such as in an office, mall, showroom or cinema - has become worrisome.
As a pioneer in air conditioning solutions, Blue Star met the challenge head on and through new design and testing, has within a few months of the advent of the pandemic, introduced many innovative technologies into the market that help neutralise the coronavirus effectively, thus making air conditioned spaces safe again.
One of the innovative products launched by Blue Star is the Special Filter with Virus Deactivation Technology that can be retrofitted into existing ducted systems to make the cooled air pure and virus-free.
The Special Virus Deactivation Filter is essentially a combination of a special filtration material coated with a patented chemical for use in ducted systems.
When the cooled air passes through this special filter, viruses including the novel coronavirus and harmful bacteria are effectively neutralised, ensuring that the air passing into the cooled space is safe to breathe and does not spread infections like COVID-19, TB, chickenpox, or even the common cold and influenza, etc.
Since the filter is easily retrofitted in most ducted systems, this is an ideal and practical solution to quickly make commercial spaces customer-friendly again by replacing all filters with the Virus Deactivation filter.
HOW DOES THE TECHNOLOGY WORK?
Virus Deactivation Technology, powered by Livinguard Technology, has been proven to be very effective in removing air-borne viruses and bacteria. Researchers at the Free University of Berlin at the Institute for Animal Hygiene and Environmental Health, for example, have been able to demonstrate that textiles treated with Livinguard Technology can destroy 99.9% of SARS-CoV-2 (the virus that causes COVID-19).
The underlying principle of Livinguard Technology is the ability of the surface treated with a special chemical to deactivate microorganisms including bacteria, viruses, and several types of fungi, and to do so without leaching.
The inactivation mechanism of viruses is based on the distortion of the protein capsid by adsorption of negatively charged proteins to the positively charged surface, finally leading to the release of non-infectious RNA.
When a filter is coated with a chemical that must act on the microbes, it is important that the chemical does not leach, or wear away, over a period of time, or on washing the filter.
That is why Blue Star’s special deactivation filter is coated with a chemical that does not use traditional metal based antimicrobial agents like silver, copper, zinc, etc. to inactivate bacteria and viruses, and maintains properties even after multiple washes, and is safe for the skin as well.
FEATURES & BENEFITS
AVAILABLE IN ALL SIZES
Blue Star’s special virus deactivation filters are being manufactured to all standard sizes, so that they will fit almost every AC unit already in operation. Thus, retrofitting is easily possible.
For large volume special requirements, contact us for custom sizes as well.

Why is Duct Cleaning important?
Most people do not realise that airborne contaminants are drawn into your air conditioning ducts, and once they enter the air conditioned space, they end up polluting the indoor air. Duct cleaning helps eliminate bacteria and mold which form inside your ducts over a period of time. Regular duct cleaning ensures that the occupants breathe clean and pollution-free air. The National Air Duct Cleaners Association (NADCA), the Air Conditioning Contractors of America (ACCA), and the US Environmental Protection Agency (EPA) recommend that the complete HVAC system should be cleaned to prevent re-contamination. This is achieved by removing the contaminants all the way from the entry of air to its exit including all internal surfaces of the airstream - air handling units, fans, coils, mixing boxes, variable air volume boxes, heat exchanges, condensate drain pans, ductwork and components in which air travels through or across.
Regular duct cleaning also improves the efficiency of the complete air conditioning system, extending its life, and ultimately saving energy and money.
How does Duct Cleaning work?
Advantages of Duct Cleaning by Blue Star
Blue Star is a certified member of NADCA. Thus, strict guidelines and standards set by NADCA are followed by us for all our services. Our Air System Cleaning Specialist (ASCS), certified by NADCA, renders efficient service every single time regardless of the complexity of the project. Our service technicians have immense knowledge of the tools and tackles. They use equipment ranging from the widest range of brushes, innovative brush adapters and gears to achieve the best results, all in line with NADCA’s standards.
Strengths of Blue Star’s Duct Cleaning Services
Unique Solutions from Blue Star
Robotic HVAC Duct Cleaning: The HVAC ducts are inspected and decontaminated using the robotic system ensuring maximum efficiency.
Disinfection: We use a Hydrogen Peroxide (H2O2) based chemical to disinfect the facility after the duct cleaning activity thereby killing all the unseen viruses, bacteria, fungi and other pathogens in the facility. This chemical releases nascent oxygen which will kill all of them resulting in a safe and healthy space. The area should not be used for 3 to 4 hours after the application of the chemical.
Most often, the spread of COVID-19 from person-to-person is believed to happen due to close contact with someone infected (about 6 feet or 2 metres). This spread is thought to occur mainly via respiratory droplet nuclei produced when an infected person coughs or sneezes, like how influenza and other respiratory pathogens spread. These droplet nuclei can land in the mouths or noses of people who are nearby or possibly be inhaled by them into their lungs.
For the most effective microbial control, UV germicidal emitters are installed on the supply side of an HVAC system, downstream from the cooling coil and above the drain pan. This location provides more effective biofilm and microbial control than in-duct UVC installations.
The recirculating air in HVAC systems creates redundancy in exposing microorganisms to UVC, ensuring multiple passes so the light energy is effective against large quantities of airborne microorganisms.

UVC Emitter for a Ducted System
Hand-held device for decontamination of surfaces infested with mold, bacteria or viruses:
The user slowly passes the device closely over the contaminated surface area, allowing the energy from the high output UVC Emitter to decontaminate surfaces. An aluminum safety shield prevents direct exposure to UVC energy, while also adding reflectance that increases the light’s effectiveness.
Steril Wand- A Hand-Held Device for Disinfection of Surfaces
Portable air and surface disinfectant
The mobile unit equipped with high output UVC Emitters provides a safe and effective way to decontaminate surfaces infested with mold, bacteria and viruses. The user wheels the mobile unit into the infested area, leaves the room and turns on the unit remotely, allowing the energy from high output UVC Emitters to decontaminate walls, table tops and other surfaces. UVC technology uses no chemicals, produces no ozone or other toxic contaminants.
