Don’t just trap, destroy
Clean air has never been more important. So we made hospital-grade air purifiers available to businesses.
99.97% effective, tested by independent laboratories.

Destroy 99.97% of airborne viruses.
Rensair’s design incorporates a powerful UVC lamp located in the centre of the cylindrical high-quality HEPA13 filter. The patented design ensures that the UVC light continuously disinfects the HEPA13 filter, resulting in a safer product.
Rather than merely capturing viruses and bacteria, Rensair’s UVC light kills them while they are trapped in the HEPA13 filter.





Scientifically developed by our engineers.
How Rensair air purifier works.
The Rensair air purifier destroys viruses and bacteria while most conventional air purifiers simply collect and trap.
- Rensair takes in surrounding air from the top and it travels through a pre-filter, trapping larger particles and dust. The pre-filter is easy to remove from the top of the Rensair air purifier to clean and will not have to be changed.
- A powerful fan (up to 560 m³/hour) pushes the air into a cylinder-shaped HEPA 13 filter below.
- As particles hit the inside surface of the HEPA 13 filter, bacteria, viruses and other airborne microorganisms are stopped. The continued air flow keeps the microorganisms stuck on the filter surface while the UVC lamp, in the centre of the cylinder, continuously illuminates the entire filter surface, thereby “disinfecting” the surface by destroying the DNA in bacteria, viruses, etc. Destruction on the filter surface further reduces the potential for contact with hazardous material during filter change.
- A large volume of clean air leaves the Rensair at 360 degrees.

How a Danish engineer created Rensair.
“My work as an engineer has always involved clean air”
– H. Hendriksen
– H. Hendriksen
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.
It is his life long experience with ventilation technology combined with a heartfelt desire to help relieve his son from a severe allergy that paved the way for the Rensair invention.
Today, a decade later, twin brothers Frederik and Christian Hendriksen lend their extensive background in business development and finance to the family business, bringing a technology they grew up with to the world.
Read the full story
Early in his career, Henrik created air ventilation technology solutions for the welding industry that went on to become the mandated government standard in Scandinavia and throughout multiple European-wide directives. The Norwegian Minister of Health challenged Henrik and his team to develop a new ventilation technology that would half the industry threshold. They did so with success, and as a result re-defined the industry expectations and requirements.
This achievement and expertise led him to be appointed representative of Norway at the European industry association EUROVENT for 5 years (the equivalent of ASHRAY in the USA and HEVAC in the UK).
Later made Chairman of the Board of Vestas Aircold and hired by BMW as its expert adviser on the subject, Henrik was involved in designing the ventilation systems for its German factory and for a variety of other industrial applications before happily retiring to raise his family.
When his son Christian developed severe allergies as a child, Henrik put his experience to the test. Significant investment went into product development and testing, and what started out as a quest to help his son, ended up developing into a medical-grade patented solution sold to hospitals, institutions and care homes across Scandinavia. Henrik had carefully combined hospital-grade equipment and the most advanced technology in a portable design. And with that, the Rensair technology was born.
Henrik explains that his invention is “a clean investment in health and care with UVC & HEPA13 filters, no biological air pollution, less risk for infections and spread of diseases, better indoor climate, and the highest product quality.” Not to mention, he is thrilled that he was able to help his son with his allergies so that he could grow up to be the healthy entrepreneur that he is today.
