Expella Wins Gold at Good Design Awards

We are honoured to have been recognised with a prestigious Gold Accolade at the 2021 Good Design Awards – the highest honour for design and innovation in Australia.

Our Shadowline Diffuser was a winner in the Product Design category, impressing a jury of more than 70 local and international experts including designers, engineers, architects and thought leaders.

So what is it?

The Shadowline Diffuser is a discreet ventilation solution for bathrooms and laundries, as the exhaust diffuser is housed inside the ceiling at the ‘shadow line’, or the junction with the wall. The concept was also recently adapted for use in air conditioning systems, making it even more versatile and effective product.

The Good Design Awards Jury commented on the Shadowline Diffuser saying, “this is a great innovation that achieves the design intent of being nearly invisible after installation, without compromising on ventilation.”

Wes Quick, Managing Director of Expella, said he was thrilled to see Expella’s hard work on the Shadowline Diffuser recognised.

“At Expella, we’re passionate about creating healthy home environments for our customers, so it’s an honour to see our product praised by the wider design industry,” he said.

“We know that the health of a dwelling is drastically improved by effective ventilation to control condensation, mould, indoor humidity and other pollutants, resulting in improved air quality.

“The Shadowline Diffuser ensures that you can still achieve the best possible design outcomes, without compromising on ventilation performance.”

On that occasion, it was the Milu Odourless toilet that received a ‘Best In Class’ Accolade for Product Design Hardware in the Building category, while the Humidity Sensor received a Good Design Award Gold Accolade in the Product Design, Hardware and Building category.
