Research setup air cleaning in fitness room

Ventilation and air purification allow gyms to open safely

The combination of ventilation and air cleaning is very effective in reducing aerosols containing germs in gyms and fitness rooms. This has been shown by research conducted by TU Eindhoven.

Shortly after the outbreak of the coronapandemic, TU Eindhoven and Sports Innovator of the Ministry of Health, Welfare and Sport launched a study to discover how gyms could safely reopen.

Research on mobile air cleaners

Professor Bert Blocken of TU Eindhoven studied the effectiveness of mobile air cleaners for filtering aerosols from the air. These very small droplets spread virus particles over a long distance through a room.

Air cleaning in fitness areas

His first research took place in a gymnasium where 35 people were actively exercising. Ventilation alone does not remove aerosols, was Blocken's first conclusion.

Even if the ventilation is set to maximum, aerosols remain in the room, he told EenVandaag. This is especially true when exercising intensively.

The combination of ventilation and air purification proved effective. With it, he achieved reductions of 80 to 90 per cent.

Plasma air purifier

For the study, Blocken used a plasma air purifier with an effectiveness of 98.5 per cent.

This is lower than the air purification capacity of AIR8 air purifiers, which remove 99.97 percent of viruses, bacteria, fine dust, odours and harmful gases from the air. This result is achieved by a medical-grade HEPA filter in combination with a number of other filter technologies, which render the filtered particles harmless.

Ventilation standards insufficient

In addition to the techniques used, it is also essential to install air cleaners of the right capacity. Since the corona pandemic, it has become clear that the ventilation standards in the Buildings Decree are insufficient to sufficiently remove pathogens and harmful substances.

The Buildings Decree from 2005 states that every person must have at least 3.5 litres of clean oxygen per second per cubic metre at his or her disposal. For gyms, this is in any case insufficient. The NOC*NSF uses 10 to 15 litres of clean air per second.

Determining capacity

Blocken says that the combination of ventilation and air cleaning can clean between 20 and 40 litres of air per second.
