Most HEPA Air Purifiers Are A SCAM (There's A Better Option)

Video Description

Free email course: 5 mistakes I made that worsened my home's air quality, and what to do instead. Sign up here: https://renegadeairquality.com/ In this video, I present a staggering amount of evidence demonstrating that HEPA air purifiers are not as effective as Corsi-Rosenthal Boxes and other DIY air purifiers. I also talk to Wayne Westerman and Rob Wissmann, co-founders of the company Clean Air Kits that sells air purifiers that are quieter, more powerful, more energy efficient, and cheaper than commercial HEPA air purifiers. This video is a journey. By the end of it, you'll learn exactly how to dramatically improve your indoor air quality by using air purifiers (AKA air cleaners). You'll also learn why you should. You'll learn about a better metric to evaluate air purifier performance so you can never be scammed into buying an ineffective unit again (Clean Air Delivery Rate, or CADR). UPDATE!
