The Birdie C02 Monitor 2.0 is a small physical sensor that monitors bedroom air quality by tracking CO2 levels. The bird tilts down when CO2 rises and lifts back up as the room ventilates, providing immediate visual feedback without requiring an app or screen.

A breath of fresh air for your home
Birdie is more than just a CO2 monitor; it is a stylish and effective way to improve your indoor air quality. The minimalist design seamlessly blends into any space. What I love most is the design and simplicity. No complicated apps or settings. Just plug it in, and it starts working. The battery life is impressive.

An eyeopener working from home
Easy ordering, quick delivery, easy installation. The Birdie works fine and it has been an eyeopener how often during the day working from home you should refresh the air.

Kids love watching Birdie go back up
My kids love watching Birdie go back up when we have achieved fresh air levels again. Easily hung on the wall, charging was a breeze and I just love it. If you are a visual person and want to monitor your air better, get this.

My wife thought it was a waste of money
I purchased the Birdie and as we already had a carbon monoxide detector my wife thought it was a waste of money. On the first night it was installed we had the wood burner on and as the evening went on the Birdie started to drop. We opened the window and within minutes it came back up. Now my wife is a convert.
