Contrary to what many may believe, it is quite difficult to predict how long it takes volatile organic compounds (VOCs) to off-gas from new materials in a specific building.  Sure, you can do chamber studies under controlled conditions to determine emission or concentration decays, but how the material will behave in the real world can be quite different. On Friday I was hired to perform a follow-up assessment for a home under construction that is experiencing elevated VOCs from varnishes and paints applied almost 7 months ago.  One month ago I was in the home and found some very high levels based on measurements with a photoionization detector (PID).  While PIDs are not as accurate or detailed as other methods of measuring VOCs, they can be used as a good screening tool with immediate feedback.  I’ll write a blog post on the advantages and disadvantages of PIDs in the near future. During my follow up visit a month later, I saw a 40% reduction after he followed some of my recommendations listed in this blog post: Reducing VOCs.  

Unfortunately, this was still 4 times the outdoor levels.  We opened up some windows in a room and very quickly we saw a significant reduction.   aerus lux guardian air purifier reviewHere are a list of the problems:hunter air purifier model 30711 The home uses 2×6 “advanced framing” making the walls better insulated and tighter.  trion air purifier indiaHowever, the home is not bringing in mechanical ventilation.  Many states have laws requiring mechanical ventilation. The owner selected hardwood floor varnish and oil-based paints high in VOC content and emission. He should have used products listed in the GREENGUARD Environmental Institute Product Guide. The owner moved in before the home was complete.  

It would have been better to wait for the VOCs to dissipate more. So back to the question at hand… how long does it take?  We can find some answers in a recent article in the Indoor Air Jounal titled “Decreasing concentrations of volatile organic compounds (VOC) emitted following home renovations”.  The authors found a return to “normal” VOC levels after 2-3 months.  The research was based on “real life” studies in Germany, not chamber tests. Use the 2-3 month timeframe only as a guide, as my experience in the tight home with strong sources indicates it can take much longer. Looks like you didn't complete your reservation.

Germ Guardian 3-in-1 Air Cleaning System I like this product. Less than half an hour after cooking, the smell goes away Best price and high quality Hey guys I bought this product after doing my research and decide to buy it. I am so happy with my decision. Low noise and eliminate the air germs.

Breathing is better now than before. I would recommend this. gets the job done right I got this couple months ago, at the beginning it produced a plastic-like smell, but i went away quickly. It gets rid of odours very well, very useful when cooking or for the bathroom Smells toxic sometimes -- produced a chemical odor that gave me a headache. I put it in the bathroom overnight and it went away, but it's the last thing you want from something that is supposed to be for health. It doesn't really remove odors or stale air. Have no idea if it's doing anything besides making noise, actually.
