(RRP: 334.-, i.e. 167.- each)

This is TWO Airvida M1 - with a charger. 

Airvida M1 is the smallest air purifier in the world. It weighs only 20g and can be easily worn with a titanium necklace or a collar clip on everyday clothing. When placed on its charging station, Airvida M1 can become an elegant tabletop air purifier. Airvida M1 constantly generates 2,000,000 negative ions/cm3, 100 times more than the natural forest ion concentration, to clean PM2.5, pollen and smoke around your face. It is a perfect solution to improve air quality outdoors or in the office, car, restaurant, public transport, etc.

Titanium, which is often used in medical devices and known for its antioxidant and anti-inflammatory properties, can be worn with Airvida M1 in your daily life. Through the Airvida M1, 2 million negative ions are generated around your face that bind airborne particles (including PM2.5, formaldehyde (CH2O), allergic substances such as smoke, dust mites, pollen and pet hair), turning them into larger and heavier clumps and causing them to fall to the ground.
