Does Rensair Air Purifier Kills Corona Virus? How it Works

Clean air for every space. Portable hospital-grade air purifier developed for Scandinavian hospitals, and trusted by businesses globally.

Rensair removes 99.97% of airborne viruses and pollutants

Clean air has never been more important.

The Rensair air purification technology was developed decades ago for Scandinavian hospitals, meeting strict air quality requirements.

Today, the Rensair air purifier is trusted by some of the largest companies globally as we continue to pursue our mission of bringing clean air to every space.

Trusted by businesses globally

  • Hospital-Grade Technology

    Originally developed for Scandinavian hospitals, the Rensair patented solution uses the most advanced air purification technology. Each air purifier consists of a germicidal ozone-free UVC light placed in the center of a cylindrical high-quality H13 HEPA filter. This captures and also inactivates viruses and bacteria trapped on the filter surface.

  • Tested by Independent Laboratories

    Independent worldwide leaders in science and technology have extensively tested the Rensair air purifier technology incl. Eurofins, Norconsult & Oslo University Hospital.

  • Large Cleaning Capacity

    Rensair cleans up to 560 m³ air per hour. This means that one Rensair air purifier can clean a room of 230 m² with normal ceiling height per hour. Use a combination of multiple Rensair air purifiers in larger spaces to maintain the same efficacy.

  • Effective Air Circulation

    Rensair’s patented design and powerful fan create effective air circulation ensuring all air in the room is purified, as documented by the independent consultancy Norconsult.

  • Easy to Use

    It takes just one person to set-up Rensair and no installation is required. Just turn it on to start purifying the air. Operate Rensair with controls on the machine or by using a remote. Wheel mounting makes it possible to maneuver the air purifier between locations.

  • Low and Safe Maintenance

    You only need to change the HEPA filter after 9000 hours of continued use (1 year).
    Rensair’s patented design featuring continued germicidal UVC illumination of the filter surface keeps the filter clean from pathogens and is therefore safe to change.

How does it work?


The Rensair air purifier sucks in the surrounding air from the top inlet perforations. Air travels through the removable pre-filters placed at the top of the machine, which catch and trap larger airborne particles and dust.

2. FAN

A powerful fan pushes the pre-filtered air down into the cylindrical shaped H13 HEPA filter located in the middle of the unit. The fan creates a high static air pressure in the cylinder which is a necessity to allow for sufficient air flow through the high quality H13 HEPA filter and enables a large air cleaning capacity.


As air hits the H13 HEPA filter, bacteria, viruses and smaller airborne particles and pollutants become trapped on it’s inner surface.


An 18w UVC lamp placed in the center of the cylindrical drum continuously illuminates the entire filtration area. This UVC light breaks down the DNA and RNA of pathogens and thereby inactivates them. This continuous disinfection process ensures that the Rensair air purifier is always safe to operate and maintain.


Large volumes of clean air travels out of the unit via the lower perforations. The cylindrical shape of the Rensair Air Purifier allows air to flow out in every direction thereby making it suitable for almost all locations.

Invented in Denmark, decades ago

The Rensair air purifier was developed decades ago by Henrik Hendriksen, a Danish engineer and inventor. For five years he represented Norway at the indoor climate association EUROVENT, helping to set the industry standard for truly clean air. His life-long experience with ventilation technology, combined with a desire to help relieve his son’s severe allergies, led to the development of the Rensair air purifier.

Today, Henrik’s twin sons Frederik and Christian Hendriksen continue to manufacture and distribute this technology worldwide.
