Air pollution is an important issue in China, particularly in Shanghai. When I became CEO of Beaumanoir Garments in China, almost two years ago, I quickly decided to equip our offices with air purifiers. 400 people work in 2000m² of office space, and it is the responsibility of the company to protect them and guarantee their well-being at work. We launched an invitation for tenders from a number of companies specialised in the sector and, utimately, selected TEQOYA for 3 reasons: their ionization technology – soundproof and not very visible compared to devices with filters -, their extremely low operating and maintenance costs, their support and commitment. Preliminary results are most encouraging since air pollution has been divided by three, which is remarkable for large high ceiling spaces. My teams are fully satisfied, and so am I.
