Indoor Carbon Dioxide Detector Birdie 🐦 After much deliberation, this product finally arrived at my home just as I was planning to buy one. Except for my daily commute, I work from home constantly, and my routine involves sitting at my desk for over 11 hours. So, I run my air purifier all day long, but I've heard that standard air purifiers can't measure carbon dioxide. That's why I think using them together is better. The design is cute, so it looks like a decorative item wherever you place it. It's easy to install and move around, so I've been using just one unit in various spots lately. Key Features The World Health Organization recommends ventilating every 1,000 mps of carbon dioxide. If the reading stays above 1,000 for more than 10 minutes, Birdie goes down, and then goes back up once the reading returns to an appropriate level after ventilation. It's even better because it operates silently, relying solely on motion. It uses USB-C charging and lasts for 8 months on a single full charge. . . #CornSoupRecordBook
