I saw this on Monday via reddit and because I children in my home I was really concerned. I first noticed that the meter used for this testing was a low grade tester. I decided to tackle this head on and find a reputable place I could rent a higher grade tester. I found Pine Environmental.

This is the meter I rented. I ran numerous tests. One thing to note is that a test sample for this higher grade unit requires 60 seconds before it displays a PPM reading. The user in the other video was walking around was a lower grade unit by comparison. I am working on uploading videos now but overall this is FUD. No high levels whatsoever on my A3 or my L3+s. Readings right at the fan exhaust were .06 ppm and at 1 foot away from the exhaust fan .02 ppm. My wood floors had higher levels of HCHO than my miners did.

Stay tuned for the videos.

do you have a minimum? What do you define as bulk?
