Inside the Air We Breathe

We take around 20,000 breaths every day, yet most of us never think about what’s actually in the air we breathe.

According to the U.S. Environmental Protection Agency (EPA) and the American Lung Association, indoor air can be two to five times — and sometimes even up to 100 times — more polluted than outdoor air.


It’s filled with microscopic particles 30 times smaller than a human hair, created by everyday activities like cooking, cleaning, burning candles, or using scented products.


These ultrafine pollutants called PM2.5 can enter the bloodstream and reach the brain, contributing to fatigue, brain fog, sleep problems, and long-term cognitive decline (PMC, Indoor Air Quality in Buildings: A Comprehensive Review, 2021).

After years of researching the connection between air quality and brain health, Dr. Austin Perlmutter — an internal medicine physician, global health educator, and NYT bestselling author — discovered that 95% of air purifiers on the market fall short of their promises:

Why Other Purifiers Fall Short

1. Many are marketing inventions, capitalizing on consumer hype with “filter” terms that don’t exist in science and aren’t third-party verified


2. Some use ionizers or ozone generators to pull in dust — a method that can produce harmful ozone, which irritates the lungs and airways (EPA Ozone Generators That Are Sold as Air Cleaners, 2021)3. 


3. Others are small, underpowered units that purify only a single room, failing to clean the air throughout the home.
