After more than 75 years of innovating filtration devices for the auto and manufacturing industries, Mann+Hummel was seeing erosion in the business due to regulations and restrictions on internal combustion engines. By 2030, Mann+Hummel expects the auto oil filtration market to be completely obsolete.

Partnering with Interbrand, Mann+Hummel created a new line of products and services to focus exclusively on indoor air filtration. The OurAir brand provides clean air solutions for indoor spaces that combine world-leading filtration expertise, engineering innovation and a deep commitment to the well-being of customers.

Interbrand developed strategy, verbal and visual systems that would seamlessly integrate OurAir with the current Mann+Hummel masterbrand and create distinctiveness in the crowded filtration market. In addition to the rebranding effort, a series of digital tools were created to help customers monitor and manage air quality in real time.
