Review on Air Formaldehyde HCHO DIY Test by Doug Layman

I really appreciate that this test has a color scale that makes it pretty easy to tell how much formaldehyde is in the air. We noticed that some of the new furniture in our office was smoking. Since it turned out to be 0.30ppm, we know that meets OSHA guidelines. We delayed the use of people running a fan to speed up the gasification process and everything is fine. This avoided the much higher cost of determining which drug needed to be manufactured. AFTER THINK: If you're having trouble identifying shades of blue, ask someone to help you rate the scale. This is clear to those who see the blues without problems.
