Birdie® is a Fresh Air Monitor™ that uses a Swiss‑engineered CO₂ sensor to detect indoor carbon‑dioxide levels and physically drops when concentrations exceed 1,000 ppm, prompting users to ventilate. The device runs up to eight months on a rechargeable battery, mounts silently on the wall, and is made from 70 % post‑consumer recycled plastic, offering a simple, visual cue for healthier indoor air without apps or alerts.

Problem
Many people spend the majority of their time indoors in spaces where carbon‑dioxide levels rise unnoticed, leading to headaches, reduced concentration, fatigue and long‑term health risks. Traditional air‑quality monitors often require apps, screens or complex data interpretation, making them impractical for everyday use.
Solution
Birdie® is a Fresh Air Monitor™ that provides an immediate, visual indication of indoor CO₂ concentration using a high‑precision Swiss sensor. When CO₂ exceeds 1 000 ppm for more than ten minutes, the device physically drops, prompting the user to open a window; it rises again once levels fall below 950 ppm. The product combines award‑winning Danish design with 70 % post‑consumer recycled plastic, operates for up to eight months on a rechargeable battery, and requires no sound, light or smartphone notifications. By turning abstract air‑quality data into an intuitive, non‑intrusive cue, Birdie helps occupants maintain healthier indoor environments with minimal effort.
Target Audience
Birdie is aimed at homeowners, office managers, and educators who need a low‑maintenance way to monitor and improve indoor air quality in living rooms, workspaces, classrooms, or shared environments.
