So, if I have to address this issue for my 1-st floor, what would be the most effective and sensible approach?
1. Tying it into the central air distribution system with inlet on the side of the house?
2. Standalone intake unit?
Though there are several challenges immediately arise
1. How to synchronize the operation with exhaust fan?
2. How to measure volume of required MUA?
What are the best DIY methods to measure natural infiltration
TIA for any insight on this matter
