Australian innovation and excellence in residential and commercial ventilation systems

Expella is an Australian business specialising in healthy, architectural and effective mechanical ventilation solutions.

Founded on good design principles and practicality, Expella’s approach means that homeowners, architects, designers and builders no longer need to settle for unattractive grilles, squashed ducting and underpowered fans.

With Expella’s range of architectural grille designs and airflow system solutions, you have function and form. And our systems are more than just beautiful; wherever possible, our designs reduce noise, increase airflow and make installation simpler and more secure.

Our approach is best exemplified by our world-first odourless toilet. Odourless by Expella is a self-contained ventilation system that runs inside the toilet cistern to send odours straight to the sewer. No more putting up with toilet odour travelling up from the bowl and around the room before it reaches a window or extractor fan.

Expella products have provided years of health and comfort in commercial buildings and more than 13,000 homes around Australia.
