windo® 2025 annual review

2025 was a year of trust for us. We would like to express our sincere thanks to all our customers and partners who have accompanied us on our journey toward cleaner air in restaurants, indoor playgrounds, and company lobbies. None of our projects would have been possible without you.
For 2026, we wish you full houses: full restaurants—such as Koogi in the Main Taunus Center—and enthusiastic guests in your indoor playgrounds.
