Air Quality

Wonder why you always feel sleepy at work? Do you want free focus boost every day? Imporve the air quality of your workplace.

As I complained from my last gig that office we rented at WeWork is too small and we fit 5-6 people in there. I constantly feel uncomfortable. I dig into why.

Coworking spaces, cafes, modern home are sealed properly so the room can stay warm efficiently or stay quiet. Recently there is a trend to introduce these small phone booths or offices:

This is very bad for your health due to Formaldehyde Poisoning.

CO2 over certain amount in a closed room can be bad for us. You will have symptons like headache. The temperature and humidity also come into play. So basically we want fresh air flows in and out of our workspace.

CO2 effects to health


  • 250 - 400 ppm: background (normal) outdoor air level.
  • 400 - 1,000 ppm: typical level found in occupied spaces with good air exchange.
  • 1,000 - 2,000 ppm: level associated with complaints of drowsiness and poor air.
  • 2,000 - 5,000 ppm: level associated with headaches, sleepiness, and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present.
  • 5,000 ppm: this indicates unusual air conditions where high levels of other gases could also be present. Toxicity or oxygen deprivation could occur. This is the permissible exposure limit for daily workplace exposures.
  • 40,000 ppm: this level is immediately harmful due to oxygen deprivation.

If you’re a employer and want your people to work better, improve your workplace! To measure you can buy AWAIR. To improve you can buy ALEN or Dyson’s Air Purifier.

I hope to see a future employer promote their opening and say:

Great place to work. We keep CO2 under 1000ppm per hour at our office!
