After testing this for a while, I wanted to share this new air intake system for my lab, which is working well, in case anyone else is interested.
A 6-inch hole was drilled through the wall to the outside, and ductwork went to the filter box:

At the end was placed a heated duct fan called a "Hotpod."

The Hotpod includes a thermostat. It raises the cold air (during some parts of the year) quite a bit. (Or the fan can be run without heat.) It will take some time to install this system. It needs to be wired to a dedicated 15-amp breaker, plus the thermostat needs to be placed and wired. But it has been well worth it.

Re: fresh air intake for lab
Thank you for sharing.
So you have air intake and "outtake" in your lab? From what I understand this blows new and warmed air into your lab, and I suppose you have an air extraction somewhere?
Thank you

Re: fresh air intake for lab
Thanks. Yes, I already had an output duct with two duct-fans in tandem, which removed air from the lab, directly to the outside. In a colder area such as mine, this involved a lot of heat loss, which was expensive due to my electric baseboard heaters. I think a simple opening to the outside would work about the same, which would allow the incoming air to exit the lab easily. How air-tight the lab is would make a difference. If air can escape fairly easily, and I assume it can in most labs, then it might not be necessary to add an output duct.
