The Flow — Smart Ambient Air Quality Monitor

You cannot see bad air. You cannot smell CO₂ building up. You cannot feel VOCs accumulating. But your brain can — as slower thinking, flatter energy, and a focus that quietly drains away without explanation.

The Flow sees it for you.

A precision 5-in-1 ambient air monitor that sits on your desk and reads your environment in real time — CO₂, TVOC, formaldehyde (HCHO), temperature, and humidity — displaying the result as a continuous ambient LED ring that shifts from calm green to warning amber to critical red as your air quality degrades.

No app required. No dashboard to check. No subscription. The ring is the interface. When it turns amber, open a window. When it turns red, leave the room. Your air quality, communicated in one glance.

The science behind it

CO₂ above 1,000ppm — a level a sealed home office reaches within 45 minutes — reduces cognitive performance by up to 15% and creative output by 50%. Formaldehyde and TVOCs from furniture, flooring, and adhesives accumulate invisibly and contribute to headaches, fatigue, and eye irritation. These are not edge cases. They are happening in your room right now.

The Flow measures all five variables simultaneously, updates every 10 seconds, and alerts you the moment your environment starts working against you.

Built for the desk. Designed for focus.

The Flow's compact form fits naturally into any desk setup — beside your monitor, on a shelf, on a standing desk surface. The LED ring provides ambient feedback without demanding your attention. It is the only air quality tool designed to live in your peripheral vision rather than in your hand.

• Sensors: CO₂ (NDIR), TVOC, Formaldehyde (HCHO), Temperature, Humidity — 5 variables, 1 device
• Display: Ambient LED ring — Green (clean) → Amber (moderate) → Red (poor)
• Update rate: Real-time readings every 10 seconds
• Interface: Zero-app operation — LED ring reads instantly at a glance
• Power: USB-C powered — one cable, runs continuously on any desk
• Form factor: Compact desktop profile — fits beside any monitor without dominating the surface
• Who it's for: WFH professionals, biohackers, parents in home offices, anyone optimising their cognitive environment

Airthings charges $79.99 for a single-sensor CO₂ monitor with no ambient display. The Flow measures five variables and shows you the answer in one colour. You decide what's worth more.
