Formaldehyde levels in indoor air in homes depend on a number of factors including: Now formaldehyde levels in mobile homes are typically around 100 µg/m3 or less (2). According to the centers for disease control and prevention (cdc), acute and chronic health effects from exposure to formaldehyde vary depending on individual sensitivity.
These levels are in agreement with data found in the scientific literature. The best approach to protecting yourself from the harmful effects is by limiting exposure to vocs. There is evidence that some people can.
Formaldehyde is an extensively regulated material. In one study, formaldehyde levels in homes were associated with increased risk of atopy, after ruling out confounding from other indoor air pollutants (garrett, et al., 1999).in another study,. 50 µg/m³ (or 40 ppb) based on a.
Epidemiological studies on the effects of chronic formaldehyde exposure consistently found respiratory and allergic effects at levels below 123µg/m 3 (health canada, 2005). Long story short, our voc levels tested in the severe range at 7100 ng/l. This means that most people are coming into contact with some amount of formaldehyde.
In minnesota, outdoor levels of formaldehyde average about 2.0 ppb. These data are relied upon in this review as the basis for deriving an acceptable residential indoor air exposure limit for formaldehyde (i.e., 24 hours/day, 7 days/week). What are safe voc levels?
Areas were in the range of 11 to 20 parts per billion (ppb). Greater than 0.1 percent formaldehyde and materials capable of releasing formaldehyde into the air at concentrations reaching or exceeding 0.1 ppm.

Eye irritation, sore throat, nose burning, and headaches.
Awareness about the health risks of formaldehyde is increasing, and exposure exists for all housing types across america. Formaldehyde levels ranging from 0.10 to 3.68 parts per million (ppm) in homes. Safe indoor formaldehyde levels should not exceed 0.10mg according to this test.
High concentrations may trigger attacks in people with asthma. In 1997, a report by the u.s. The risk of developing cancer from formaldehyde levels found in canadian homes, however, is essentially zero.
After noticing a strong chemical like smell in our house, we ordered an indoor air quality / voc test. Formaldehyde levels are higher in new manufactured wood products such as flooring and furniture.
