Filterless Air Cleaners Make No Sense: Airfree Lotus Air Purifier

Honestly, it's starting to piss us off that some of these marketing teams are combining their shocking lack of understanding of what they're selling, with an assumption that their customers won't be able to understand it either. Let's fix that right now, starting with this Airfree Lotus 'filterless air purifier'. Oh, and they make one specifically for baby rooms too, if this wasn't dumb enough already.

If you need cleaner air, use good filters, or dilute with outdoor air using something as simple and affordable as an AirCycler: https://www.aircycler.com/

Whole House Fan Mythbusting

You know what I don’t like? When people try selling one product across America with pseudoscience or vague claims about benefits in home physics, chemistry, or microbiology. Here’s my rebuke to one specific instance of this kind of over-stated marketing in the world of ‘cooling your house as cheaply as humanly possible’.

Home Ventilation for the 21st Century

There's a lot of mythology and misinformation about how to ventilate homes, and here Corbett shows, with the assistance of Phil Rivas from Fantech, how a perfect ventilation system gets built with 5 classes of HVI-certified equipment.

TOOL REVIEW: DG-1000 from Energy Conservatory and Minneapolis Blower Door

Corbett gives a crash course in the TEC’s DG-1000 used with Minneapolis Blower Door equipment (including the Duct Blaster, TruFlow Plate, and Exhaust Fan Flow Meter). TEC took away a few features like Equivalent Leakage Area estimation, but added the Tubing Assistant and firmware updating, which could endlessly add features based on user feedback.

OZONE: the Original Villain of Indoor Chemistry

Indoor Air Quality is being explored at breakneck speed with the HOMEChem Experiment, and not surprisingly, ozone (O3) is proving to be the original villain in the complex system of interactions that make the air we breathe much more worrisome than anyone guessed. Featuring HOMEChem scientists Marina Vance, Delphine Farmer, Charlie Weschler, and Richard Corsi.
