How important is filtration on an ERV?
We are building a home in the metro Detroit area (climate zone 5). Last fall, I stumbled across GBA while researching mold in homes on the internet. I heard an interview of an author Rob Dunn who wrote “Never Home Alone” (which was reviewed by Peter Yost recently https://www.greenbuildingadvisor.com/article/never-home-alone). This prompted the question, how do you build a home that is healthy to live in?
I read the book and it prompted my net search on mold, and I came across Martin Holladay’s “Common Sense On Mold” https://www.greenbuildingadvisor.com/article/common-sense-mold.
Lots of reading and altering our construction plan later, I’m now choosing an ERV and lately I’ve been thinking that filtration must be important – but then I remembered “Never Home Alone”. The gist of the book is that the inside of homes is an environment and trying to alter it and clean it tends to eliminate most of the non-disease causing germs/bacteria and encourages more disease causing bacteria to thrive.
Ventilation makes sense to me – fresh air sounds logical. What should our mind set be on filtration? Is more filtration better? Should I choose an ERV that has high filtration (and uses as little energy and has high SRE)? Maybe fresh air is fresh air and filtering it doesn’t help at all…
Thanks for any responses in advance,
