[Strawbale] Comment on forced air systems and dust

[Robert Tom]

Geeze. That yakkety Don. Eh ?

I've often wondered how people with hydronically-heated SB houses without  
air-handling systems provide fresh ventilation air to every habitable  
space in the house and exhaust stale and/or polluted and/or contaminated  
air.

Perhaps "wondered" is the wrong verb.
"Speculated" is probably a better verb and as is always the case with  
speculation, there is always an answer self-ventured.

In any case, for the past few days there has been a "dust" related piece  
on the Globe & Mail website:

If you take a gander at the article, then you may also want to have a look  
at the readers' comments/feedback in the "Join the conversation" section  
on the right side of the page at the above link.
