Here’s how it works

Illustration - allergen exposure
Allergen exposure is high during sleep

While at rest in bed, your mouth and nose are in close contact with pillows, mattresses and duvets that can contain large amounts of irritating particles and allergens such as house dust mites and pet dander. During sleep your body causes an upward air flow, concentrating these airborne particles and allergens to the breathing zone.

Illustration - clean air
Air4 provides 99.5% clean air in the breathing zone

The Air4 delivers filtered and slightly cooled air that descends towards the breathing zone in a laminar manner. The clean laminar airflow counteracts the allergen-rich body convection flow.

Your body has the opportunity to rest and recharge

With the Air4 placed next to the bed and used every night at least 99.5% of particles are blocked from your breathing zone all through your sleep. This allows your airways and the immune system to rest and recuperate overnight.
