Comparetto DIY Air Cleaner Filtration Rig

Corbett Lunsford

My friend Neil Comparetto came up with a very effective, very inexpensive way to clean air for less than $100. It's not fancy, but it works as well or better than many high-end air purifiers and filtration products 'they' are trying to sell you. The important thing is that it's a fan and a filter, which is all you should ask for in an air purifying device- nothing that 'destroys', 'eliminates', or 'sanitizes' using 'electronics', 'UV', or 'plasma'. Neil Comparetto's a great HVAC expert if you happen to be in Virginia: https://www.facebook.com/comparettocomfortsolutions/

Healthy Homes for Multiple Chemical Sensitivity (MCS)

Corbett Lunsford

Tonight I interviewed Corinne Segura (https://www.mychemicalfreehouse.net/), one of my Mastermind students who helps people with Multiple Chemical Sensitivity (aka MCS, or Environmental Sensitivity), which she also suffers from herself. We discuss how home building and home improvements need to adapt to people with this condition, applied specifically to the TinyLab and our new 3,000 sq ft house that's almost finished.

Testing the Air Handler Cabinet Leakage

Corbett Lunsford

Mastermind student Treondras and I isolated the air leakage built into my Mitsubishi heat pump’s air handler cabinet using a Retrotec Duc Tester 300 and DM-32 gauge. Turns out I made the right decision with Mitsubishi! Their 5 cfm at 25 Pa beats Neil Comparetto’s 6 cfm record. Good job guys.
