How to Choose a Filter for Healthy Home HVAC: Capturing Particles vs. Chemicals

Explained using the three most available high quality filter types (MERV 11, 13 and 16), I offer a quick tour through the size range of the invisible stuff you don't want to breathe. The black carbon filter is an Aprilaire 413CBN (https://shop.aprilaire.com/collections/carbon-odor-reduction-air-filters).

Central Vacuum System with HEPA Filter: Performance Testing for a Healthy Home

For our forever home, we chose the NuTone PurePower 650 central vacuum, which I piped, wired, and installed myself (not very difficult, though parts are hard to get ahold of in a hurry, if you run out).

As a preview of the full kitchen exhaust system demonstration, here's a how-to on the hood liner, silencer, and wiring alone. As a first-time installer, I had quite a learning curve, but Fantech's tech support knows my name by now- thanks to Daniel over there for being patient with me.

Advanced Blower Door Testing Tips for Historic Home Renovation

Demo is starting soon on this 1920's home in Atlanta, and as an introduction we test the most important aspect- air leakage. This turned out to be the leakiest house I've ever tested (the test DOES include all attic spaces, since we're wanting to compare the same test before and after, and these attics will be a lot less confused when they're officially inside the house).
