Copenhagen cleantech startup Everyday and architecture studio BIG have designed a minimalist home air purifier called Air.
Described by Everyday as a complete "home climate system", Air brings together heating, cooling and air purification for the home.
The startup worked with BIG to create a purposefully subtle design defined by clean, architectural lines.
The minimalist indoor system includes a rectilinear, wall-mounted fan with a magnetic exterior. Interchangeable oakwood finishes can be snapped into place on the box via the magnets, creating a customisable product.
Users can adjust the temperature of the room using a sleek, circular control panel, which is fitted with EverydayOS – the startup's home intelligence technology that learns unique routines, patterns and preferences.
An outdoor system was also created as part of the project, contained within blocky black hardware.
Everyday co-founder Kaave Pour explained that Air was designed to give special aesthetic attention to residential cooling and heating systems, which are often overlooked as purely practical.
"For decades, designers have made the inside of the home more beautiful, more liveable, more considered," said Pour.
"But the systems running it have been left to another era – engineered, specified, and hidden, but never designed," he added.
"Working with BIG has been about asking what happens when you bring genuine design intention to those systems – the same intention you'd bring to architecture."
Air was debuted during last week's 3 Days of Design festival in Copenhagen, where projects on display ranged from an exhibition of furniture and lighting by young creatives, a series of shows centred on Japanese design and a presentation of bathing and sauna-related products.
Everyday was co-founded by Pour and and Morten Meisner-Jensen in 2025.
Established in 2005 by Bjarke Ingels, BIG is responsible for global architecture projects including the Amager Bakke ski slope-topped power plant and New York supertall skyscraper The Spiral.
