Air Cleaning Technologies That Don't Work (and Why) - Charles Nehme

In an era of increasing concern about indoor air quality, consumers are bombarded with promises of cleaner, healthier air through a bewildering array of purification devices and technologies. The global air purifier market has exploded to over $12 billion annually, driven by legitimate concerns about pollution, allergens, and airborne pathogens. However, not all air cleaning technologies deliver on their promises.

This book examines air purification technologies that either don't work as advertised, provide negligible benefits, or may even pose risks to health and safety. Through scientific analysis and real-world testing, we'll explore why certain popular air cleaning methods fall short and what consumers should know before making purchasing decisions.

Our investigation is not meant to dismiss all air cleaning technologies. Proven methods like HEPA filtration and proper ventilation have strong scientific backing. Instead, this book serves as a critical examination of the claims that don't hold up under scrutiny, helping readers separate fact from marketing fiction.
