UV Diffusers

Safe Air, Clean Air, Enhanced Ventilation

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

UV-C Air Disinfection
1. UV-C Irradiation

UV Diffusers clean 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.
*Disinfection percentage varies with the air volume passing through the diffuser

UV Diffusers use air filtration to clean the air
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.

Improved Ventilation Against COVID-19
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

Compatible with All Existing Systems

Unlike MERV-13 and HEPA filters, UV diffusers add very little pressure to the 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.

Energy Efficient Solution

UV diffusers disinfect the recirculated air from pathogens with an efficiency up to 99.9999%, which makes it unnecessary to increase the percentage of outdoor air. UV diffusers’ energy consumption is minimal, providing the benefits of using outdoor air at a fraction of the cost.

Air Disinfection Using UV-C Light in UV Diffuser by EffectiV HVAC

Safe for Building Occupants

A Safe and Reassuring Blue Glow

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

Safe Ventilation for Office Buildings With UVC Air Disinfection and Filtration
Office Buildings

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.

Safe Ventilation System to Prevent the Spread of COVID-19 in Schools
Schools

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.

UVC Air Purification System for Dentists to Disinfect the Air from Viruses and Bacteria
Dental Clinics

Dental offices are one of the most high-risk places to acquire airborne diseases. To ensure the health and security of employees, patients and professionals, proper ventilation is an absolute necessity and UV Diffusers are the solution for sanitization of the air to prevent the accumulation and recirculating of pathogens within clinics. UV Diffusers’ blue glow in the ceiling will reassure patients and staff that pathogen-free and filtered air is being delivered, allowing 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.

Preventing the Spread of COVID-19 Through Ventilation Systems in Commercial Buildings


SARS-CoV-2 is proven to be airborne and the virus particles are too small to be caught 100% by standard filters.

Some studies have shown that COVID-19 can spread from one room of a building to another through the ventilation system of commercial and institutional buildings.

UV Diffusers ensure clean and safe air in every room of the building, and can sterilize SARS-CoV-2 with an efficiency greater than 99.9999% depending on the amount of airflow passing through. They are the last object that the air passes through before entering the room. Once UV Diffusers are installed in a space, they act as a shield against pathogens and contaminants, protecting that room from the rest of the building.

UV Diffusers are effective against many other pathogens in addition to SARS-CoV-2, including Influenza and Legionella. They are not only a short-term solution against COVID-19, they will also help improve the overall health of building occupants in the long term and could help slow down future pandemics.

UV Diffusers can replace existing diffusers in the whole building, or be installed in a single space. Easy access to ceiling diffusers gives building owners and occupants a lot of flexibility in implementing this solution.

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.
