Can a simple DIY carbon air purifier remove VOCs as well as the more expensive consumer units? In this video, I build a DIY activated carbon setup designed specifically for VOCs (odors) and compare it to three well-known consumer air purifiers: Austin Air, AllerAir, and Airpura.

In indoor air quality discussions, I often hear these two perspectives:

1.) Why use an air purifier when you can just open a window (ventilation)?

2.) Don't open a window while an air purifier is running.

So who is right?

Are you aware that household products like air fresheners, cleaners, and paints are now a major source of air pollution in cities? In this video, I dive into how volatile chemical products (VCPs) contribute to outdoor pollution, surpassing even cars and factories in many industrialized areas. These products release volatile organic compounds (VOCs), which escape from our homes and react with pollutants, forming harmful particles and ground-level ozone.

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.

This is a build video in which I show you STEP-BY-STEP how to build my DIY air purifier. It is quieter and more powerful than a Corsi-Rosenthal box (aka Comparetto Cube).
