Effective against coronavirus

The Nordair air purifier protects you from the coronavirus and other pathogens. With its HEPA 14 filter, it removes over 99.995% of all particles from the air and is therefore not only effective against viruses, but also against bacteria, pollen, spores and fine dust.

The coronavirus and many other pathogens are transmitted through the air 1. When speaking and breathing, humans generate many droplets that can be contaminated with pathogens. Larger drops can be stopped with masks or fall quickly to the ground. However, the smaller droplets, also called aerosols, can linger in the air for several hours 2. Air purifiers like the Nordair Pure can filter these aerosols out of the air. There are essentially two key figures involved 2:

Volume flow and effectiveness.

With the Nordair air purifier, we offer a very powerful device at an unbeatable price.

Diverse fields of application

Air purifiers and filters must be installed wherever people have to stay in closed rooms for a longer period of time (dormitories, schools, old people's and nursing homes, care facilities, offices and other workplaces).

In the office

Working from home is not always the best solution - with the right security concept, you can also create a safe working atmosphere in the office. With the Nordair air purifier, you also protect your employees from indirect infection by fine aerosols.

At school

Education is important - that's why our children should be able to go to school safely. Regular ventilation can disrupt the lesson in bad weather or noise in front of the windows or is sometimes not even possible. The Nordair air purifier still provides you with clean air.

In care facilities

Many particularly endangered people live in close quarters in care and senior facilities. Effective measures are required to protect residents and employees. The Nordair air cleaner perfects your security concept beyond Corona.

What really matters

This makes room air purifiers with a large volume flow and high quality Class H14 filters From our point of view, it is a very useful technical solution to greatly reduce the indirect risk of infection from aerosols in schools, offices, shops, waiting rooms, community and club houses, lounges and dining rooms, etc.

Prof. Dr. Christian Kähler ²

High volume flow

The volume flow rate indicates how many cubic meters of air can be purified per hour. To be adequately protected, even in a room with several people, requires an air exchange rate of 6 - 10 per hour 2 3 4. This means that the air purifier flow rate should be about six to ten times the room volume per hour. The Nordair air purifier performs a volume flow of up to 1,100 m³/h.

HEPA 14 filter

The Nordair Pure uses high quality HEPA 14 filters. Filters in this class have been used for many years in medical facilities such as hospitals 5 6. They remove from the air over 99.995% of particles with a size around 0.3 μm, the most difficult particle size to filter 7. For smaller particles, a different physical effect takes hold. Therefore, particles of coronavirus size around 0.1 μm, or larger aerosols contaminated with coronavirus, are separated virtually 100% 2 8 9. This makes the Nordair air purifier effective against other pathogens, such as flu viruses, as well as particulate matter and pollen.

Very low costs

In addition to the low purchase price, the Nordair Pure convinces with exceedingly low running costs. With only about 70 watts in continuous operation, the device is extremely energy efficient. Our filters are significantly more durable and cheaper than competing products. This way you can save on expensive maintenance contracts.

Low volume

The school class examined by Prof. Curtius felt a volume of 48 dB (A) as not disturbing 4. This corresponds roughly to the background noise of a quiet apartment. The Nordair Pure can therefore quietly clean over 700 m³ / h. In order to achieve a sufficient air exchange rate even in large rooms, several air purifiers can be used.

No drafts, not even directly in front of it

The air flow from our air purifiers is laminar, which means that it exits the filter without turbulence. People especially feel eddies on their skin 2, which is why you can hardly feel the airflow. So you can work directly in front of the device without it pulling.

Very low maintenance

Our air purifiers are based on filter fan units. These devices are installed in the ceiling in the semiconductor industry and clean the air for highly sensitive applications. They were developed to run continuously for many years with little maintenance. Therefore you only have to change the main filter every 1-2 years. The pre-filter has to be cleaned every 6 months. That is about five minutes of work.

Effect is scientifically proven

Scientists led by Prof. Kähler at the University of the Federal Armed Forces in Munich have shown that air purifiers with a HEPA 14 filter can reduce the risk of infection 2 8 9.

In use for decades

Filter Fan Units have been used in the pharmaceutical industry for a dust-free and germ-free environment for many years.

We're rethinking these air purifiers.

I have been using Filter Fan Units in my laboratories for many years. They clean the air of all particles, coarse dust and small viruses. This not only helps me in my research, but also in offering my employees the best possible protection against pathogens.
