- our canaries - 

in December of 1986, a mining tradition dating back to the early 1900’s ended - the use of canaries in coal mines to detect carbon monoxide and other toxic gases before they hurt humans.


technology replaced the canaries with a new device called an “electronic nose”.


the nose sniffed the air and provided a digital readout showing the levels of toxic gases. in spite being unemployed, canaries could be heard throughout the land rejoicing over the news.

at 340 fairfax, we have our own set of electronic noses. they continually sense our indoor air for harmful pollutants such as:


  • Carbon Monoxide (CO)

  • Carbon Dioxide (CO2)

  • VOC’s such as formaldehyde, toluene and benzene

  • Particulates down to 2.5 microns

the best thing about our noses is that they provide feedback when there is a concern.


since most of this stuff is invisible, we would never know when we have a problem. now we know! 


if we forget to turn on the exhaust fan when we cook, guess what happens? we get a text or email saying, “pay attention!"  particulates and VOC’s are too high so do something to reduce them.


in other words, our noses teach us how to operate our home to best protect our health.

they also provide continuous feedback. so we can look at the levels anytime we want.


this is one of our feedback screens on a smart phone that is showing levels of VOC’s, CO2 and Fine Particles inside 340 fairfax. and it’s exactly what we like to see.

the number in the center is called a Global Index.


it represents a general summary of the overall healthiness of our air based on the pollutants sensed.


a zero here is as good as it gets.


you can see our number is 1. we were especially pleased to see this since it was the same day we moved in all our furniture!
