Prevent the Spread of Viruses and Bacteria Through Ventilation Systems
UV Diffusers act as a shield removing pathogens and allergens from the air coming from the ventilation system before it enters the room. The purified air is then mixed with room air with high efficiency in order to reduce the concentration of contaminants. UV Diffusers improve indoor air quality and ventilation efficiency to prevent the spread of airborne diseases.
A Three-in-One Solution
1. UV-C Irradiation
UV Diffusers treat the air using UV-C light to neutralize airborne pathogens like viruses, bacteria, and fungi. Thanks to our special plenum which integrates an ozone-free UV lamp and its design to increase air contact with UV-C rays, we manage to neutralize up to 99.9999%* of SARS-CoV-2, SARS-CoV-1, Tuberculosis, Legionella and many other pathogens.
*Irradiation performance varies with the volume of air passing through the diffuser
2. Air Filtration
A MERV-9 filter catches and traps all types of airborne particles including viruses, bacteria, dust, mites, spores and pollen. Filtering the air at the very end of the duct line prevents any re-contamination of the air after the filtration process. A common example of re-contamination is dust accumulation in the duct over time, which can create allergic reactions when the air conditioning system is running.
3. Improved Ventilation
Improving air mixing is what EffectiV HVAC diffusers are designed for. AXO high induction and PLAY adjustable diffusers provide better mixing of the new air with room air, resulting in a faster and more efficient removal of contaminants. Another benefit is a significant improvement of occupants’ thermal comfort. Better air mixing can also help optimizing the performance of the HVAC system and reduce the energy consumption.
Important: the use of this device is a supplement to and not a substitute for standard infection control practices; users must continue to follow all current infection control practices, including those related to the cleaning and disinfection of environmental surfaces.
Compatible with Older Ventilation Systems
Unlike MERV-13 and HEPA filters, UV Diffusers don’t add a lot of pressure to the ventilation system. This makes them compatible with existing buildings without needing expensive system upgrades. UV diffusers can replace most existing diffusers without issues, and even improve air distribution performance in the process.
Did you know that in most commercial and institutional buildings, up to 90% of the air is recycled and recirculated in all the rooms? Also, many of these buildings only filter the 10% of outside air added to the recycled air. We do this in order to save energy. However, many recent studies have demonstrated that this is the main cause of between-rooms transmission of airborne viruses like SARS-CoV-2. UV diffusers neutralize the microbes present in the recycled air with an efficiency up to 99.9999%.
Efficient Air Treatment

Safe for Building Occupants
UV Diffusers do not produce UV-A nor UV-B, only UV-C rays and blue light. They are designed to contain UV-C rays inside the diffuser and to let only blue light pass through in order to create the safe and reassuring blue glow you can see, symbolic of clean and safe air. The subtle blue glow is also an indicator that the system is working and actively purifying the air.
A Perfect Solution For Commercial Buildings, Including
Safety is one of the main concerns when it comes to employees returning to the office. UV Diffusers help ensure their safety and also reassure employees. They can see that measures are being taken to make sure the air they are breathing is safe. Commercial real estate is facing new challenges and upgrading your office spaces with UV Diffusers can lower energy consumption and operation costs, while increasing occupancy and building value.
Children’s education must continue and precautions are being taken such as limiting children interactions between classrooms. This helps contain potential outbreaks within one classroom only, preventing the virus from spreading between classrooms. There is, however, a risk of airborne viruses spreading through the ventilation system, but we must keep the systems running in order to ventilate the rooms and avoid high concentrations of virus particles in the air. UV Diffusers are designed to stop the spread from room to room and are compatible with existing school ventilation systems.
Dental clinics must take airborne diseases seriously. To ensure the health and security of employees, patients and professionals, proper ventilation is an absolute necessity and UV Diffusers are a perfect solution for air treatment in order to prevent the accumulation and recirculating of pathogens within the clinic. UV Diffusers’ subtle blue glow in the ceiling will reassure patients and staff that microbe-free and filtered air is being delivered, allowing them to breathe with more confidence.
Based on technologies that are proven safe and effective
UV Diffusers ingeniously combine the three proven methods recommended by ASHRAE to ensure safe indoor air quality: good ventilation, filtration, and UV-C germicidal irradiation.
UV Diffusers are not an additive air cleaning technology. They do not emit any harmful particles.
The PLAY-UV diffuser has been selected by a panel of highly respected HVAC experts.
PLAY is the only diffuser providing a full 360-degree horizontal adjustment of the airflow. Each round sector can be manually rotated from the face to redirect the airflow exactly where we need it.
PLAY allows us to also reach parts of the room which would normally lack proper ventilation, either because of the room configuration, the diffuser location, obstacles, or other factors.
PLAY also allows us to improve thermal comfort by redirecting the air away from people feeling drafts, or towards sources of heat gain/loss like large windows.
Thanks to the PLAY diffuser, HVAC technicians can shape the air circulation in the room with precision, ensuring an almost perfect ventilation in any room configuration.
