Poor indoor climate

Atmospheric dust samples taken by the University of Minnesota show that 98% of all particles in the air are below 1µm and weigh only 3% of the total weight.

Particles of this size are not moved by draughts or wind: they can travel through our airways and into our bloodstreams, causing harm. 

Air treatment

The particles are transported into our buildings via ventilation systems, open windows or from people and animals. We can reduce particles of a size <3µm by up to 90%, and fight viruses and bacteria with up to 99.50% of airborne aerosols.

Surface treatment

In addition to treating the air and making it healthy and safe, our NPBI ionisation can treat any surface in a room and render, for example, SARS-CoV-2 harmless with a proven efficacy of up to 99.98%.

There's something in the air

90% of our entire lives are spent indoors

Do you want to be in an office, a shopping centre, a treatment room or an educational institution with a heavy indoor environment including airborne and unwanted viruses? - I guess not! Indoor air can be up to 5 times more polluted than outdoor air.

Limit the amount of particles

Limiting outdoor pollutants and eliminating indoor pollutants is an easy way to improve air quality. Keeping doors and windows closed during the pollen season, choosing non-toxic cleaning products and regular vacuuming can have a positive impact on indoor air quality. 



Adding fresh air to your indoor space can help dilute the concentration of pollutants and improve air quality. 

Unfortunately, this method can also contribute negatively, depending on the weather or outdoor pollutants, such as mould, pollen or vehicle exhaust.


Treatment of the air

By controlling the amount of harmful particles that enter through the ventilation system, our NPBI Ionisation can reduce large amounts of external particles and contribute to a significant reduction of internal nuisances, such as VOCs, odours, viruses and bacteria, thereby ensuring fresh, healthy and safe indoor air.

Our biggest problem is the smallest particles
