Today we use the free @phyphox app (https://phyphox.com/) to simulate a blower door test, along with a plastic baggie, a tiny hose, and a cardboard box. Are we destined for greatness and beauty, or is it just a brain fart? You decide, nerds.
I LOVE getting my mind blown, and blowing all of yours too- here's an app that unlocks the frankly unbelievable instrumentation we've all been carrying around in our stupid pants for years. Let's get to work. Thanks @chptech for showing me the righteous path.

This steam shower exhaust system was shown to me by a client who was almost fooled- here's a breakdown of what it is and whether it truly is 'an essential part of any luxury shower'.
Ryan N. is a client of mine with a special niche that's allowed him to see behind the curtain of new home builds. He's using what he's learned to design and GC his own family home renovation, and he's got advice for others seeking the same.
Get a full tour of every piece of an active make up air system like the Fantech MUAS 750, MUAS 1200, MUA Unitary 8, and Unitary 10, and watch the setup testing needed to fully program these systems.
