Most education debates focus on curriculum, class size, and technology. One of the most cost-effective levers gets overlooked because it doesn't fit the usual framework: the air students breathe.

The 74 makes the case well. The standout evidence comes from Aliso Canyon, where a 2015 gas leak led to air purifiers being installed in classrooms within a five-mile radius. Schools just inside that line got filters; demographically similar schools just outside didn't. The result was a natural experiment — and the students in filtered classrooms saw measurable gains in test scores.

That tracks with everything we see in the research: cleaner air means faster thinking, better recall, fewer errors, and fewer absences. It's not a metaphor. It's measurable.

For schools weighing where to put limited dollars, clean air belongs in the conversation alongside the interventions we traditionally fund. It's affordable, it's proven, and the health benefits come free with the academic ones.

Stay safe! Tip: when inside, keep outdoor air from coming in and run a HEPA air purifier to remove the fine smoke particles to keep your indoor air environment a safe space.

Multiple wildfires burning across Southern California are impacting air quality and spreading smoke and ash across several communities, prompting health warnings from officials.

Clean air may sharpen your thinking.

A new randomized study in Scientific Reports found that adults 40+ who ran a HEPA air purifier at home for one month performed 12% faster on tests of mental flexibility and executive function — compared to using a sham unit with no filter. Researchers say the effect is comparable to increasing daily exercise.

Add it to the growing list of reasons indoor air quality matters: cardiovascular, respiratory, and now cognitive.

Study: Pellegrino et al., Scientific Reports, April 2026.

HEPA air purifiers can slightly boost brain function in adults 40+, potentially reducing pollution-related cognitive decline. Using a HEPA air purifier for one month may modestly improve cognitive performance in adults over 40, particularly in areas like mental flexibility and executive function.

Coconuts that clean your air? 🥥

Most people don't realize that coconut shells are one of the best raw materials for activated carbon filtration — with up to 50% more micropores than coal-based alternatives.

We use coconut shell granular activated carbon in our TrueCarbon™ filters to tackle smoke, VOCs, and heavy odors that HEPA filters simply can't touch.

Here's how it works 👇

There are two trusted and efficient air cleaning methods. One uses HEPA filters and targets fine particles like dust, pollen, and pet dander. The other method uses carbon filters (like ours made from coconuts!) and targets gasses, VOCs like formaldehyde, and heavy odors.
