The creation of Rensair started decades ago.

Henrik Hendriksen is a Danish engineer and inventor. An expert in the field of ventilation, he represented Norway at the industry association EUROVENT for 5 years, helping to influence the standard across Europe for what it means to have truly clean air.

“My work as an engineer has always involved clean air.”

H. Hendriksen

The Rensair technology was born of a life-long experience with ventilation technology combined with a heartfelt desire to help allay his son's severe allergies. Today, a decade later, twin brothers Frederik and Christian Hendriksen lend their extensive background in business development and finance to the family business to share this technology with the world.
