ERVs and formaldehyde
In the Allison Bailes interview with Dr. Iain Walker http://www.greenbuildingadvisor.com/blogs/dept/building-science/intervie...
the emerging concerns about formaldehyde transfer (or non-transfer) are discussed at the end. As stated in the interview, it's hard for the purchaser to know the exact extent of the issue with particular units, but Dr. Walker does describe the 2 methods of exchanging moisture, wheel and membrane with the latter being preferred.
I will be using an ERV on a new build in Zone 4A and would be really interested to know which ones are currently using the membrane for moisture exchange. Or, conversely, specific models that do not.
Thanks in advance for any help or guidance you can provide.
