我就这个问题真正的调查过,而不是像某些人那样,没有调查,却先入为主,无端进行人身攻击。

There is no real concerns with having the intake air being drawn from the inside of the structure.... in most cases. As long as your house does not severely go into negative pressure you will be fine. This will depend on how tightly your home is constructed. Most new homes do not come with the intake piped to the outside either. I have worked for many many large home builders, and when you are putting up 1000 homes, all they care about is saving the $100 dollars on each house.9 U( ?. ]5 k8 }7 ^. w, r* ~
