The science behind The OZO DUO

Air filter systems remove solid particulates such as dust, pollen, mould, and bacteria from the air. The OZO Duo uniquely combines UVC and HEPA air filtration technologies. The OZO DUO uses UVC light to decontaminate viruses and bacteria. This is achieved by destroying the molecular bonds that hold together the DNA.  UVC is frequently used to disinfect surgical tools and hospital rooms and is commonly used in NHS England.


The OZO Duo draws air into its vents and through medical grade HEPA 13 filters which traps any larger contaminates.  HEPA air cleaners, clean the air by removing microscopic contaminants. HEPA 13 filters create cleaner, fresher air for you and others to breathe in your space. Any remaining bacteria or viruses pass through the high intensity UVC chamber which neutralises the most resistant coronavirus ever studied with a dose of 240J/M3.

The OZO Duo uses a high-power fan to eradicate class-leading 2000m3 of air per hour.   To illustrate further, this would allow for 9 new air cycles per hr in an average 50 person office. These air filter systems are gaining momentum with organisations as a proven way to create cleaner workspaces and environments.

How does ozone gas sterilise surfaces?


The OZO Duo replaces the need for sterilising surfaces with bleach or disinfectant. Although you can neutralise bacteria and viruses with bleach these substances cannot be used on some surfaces and are not as effective as ozone gas.  Ozone gas can penetrate hard-to-reach areas, fabrics and rough and uneven surfaces. 

The OZO Duo uses 4 high-powered ozone discharge plates to create and disperse the ozone gas, fully sanitising the room.  The ozone gas is released only when the room is empty and no-one is around.  Once the ozone generator has completed its cycle, the OZO Duo switches back to UVC mode to convert ozone back to oxygen.
