Next generation air purification system

The Airofresh BCU (biological control unit)
is an award winning, globally patented air purification technology which is now distributed around the world

Developed by a team of Australian Scientists, the AiroFresh BCU employs a completely different approach to air purification.

Launched commercially in 2015, the AiroFresh BCU has received numerous awards including the coveted ARD National Environment & Sustainability Innovation Award in 2017.

Mode OF Action

Traditional Air Cleaners

Traditional air purifiers often rely on cartridge filtration systems to capture and store pollutants. The inefficiencies of this approach mean that regular expensive filter changes are needed. Multiple filter units are required due to the low air flow rate inherent in these systems.

AiroFresh BCU Air Purifier

The heart of the BCU system is the patented “High Intensity Oxidation Module” (HIOM) which creates an intenesly reactive gaseous oxidation chamber.

The gaseous mix that populates this chamber has an unusually high oxidation potential and destroys physical, biological and gaseous contaminants on contact.

The efficiency and effectiveness of the oxidation module mean that high volumes of air can be absolutely purified very rapidly.

Practically this means that many settings only require  1 or 2 units for comlete air purification, and costly regular filter replacements are not required.

Three Way Protection

The AiroFresh BCU is a commercial grade, chemical free air purification system which effectively eliminates airborne chemical, physical and biological contaminants.

These contaminants are rapidly and completely eliminated from the atmospheric air as it passes through the oxidation module.

The AiroFresh BCU is designed to purify an enclosed atmosphere wherever people work, rest or play. It has been highly successful in a wide variety of industries:

Early learning and child care centres

Fitness Centres

Food production and storage facilities

Cold rooms


Staff and customers in these centres report a significant improvement in air quality within the first weeks following installation. They particularly comment on the removal of stubborn and unpleasant odours which they had previously been unable to control.


Other significant benefits of air purification include a reduction in hay fever and asthma symptoms and a lowering in transmission of airborne infections.
