How Corn Is Powering a Cleaner Future - One Air Filter at a Time

In the Corn Belt, we know that innovation starts in the field. Today, it’s taking a powerful new form: corn-based air filters that not only clean indoor air, they open new markets for American farmers and strengthen our rural economy.

At Aerterra, we’re proud to put U.S.-grown corn at the center of a sustainability story that’s reshaping the future of everyday products. Our filters are made from PLA (polylactic acid), a renewable material derived from corn, offering a homegrown alternative to petroleum-based plastics.

And it all starts with the hard work and stewardship of our nation’s corn farmers.

A Cleaner Choice, Backed by Better Materials

A recent Life Cycle Assessment reveals that Aerterra filters made from corn-based PLA require significantly less energy to produce and emit substantially fewer greenhouse gases than conventional filters made from fossil-derived plastics or fiberglass.

While many air filters rely on materials from non-renewable sources, Aerterra’s filters are part of a new generation of plant-powered products designed for a better environmental future — one that starts in our soil.

A New Market for Corn: Beyond Food, Feed, and Fuel

For growers across the Corn Belt, expanding into bio-based products like air filters opens the door to:

• 🌽 New demand for corn outside of traditional markets
• 💼 Greater crop value through climate-smart applications
• 🇺🇸 Pride in products that are Made in America, Grown in America

Every corn-based filter presents an opportunity to demonstrate that agriculture is driving the next wave of innovation, not just in food or energy, but also in everyday consumer goods that people use in their homes.

Cleaner Air. Stronger Roots. Brighter Future.

Choosing Aerterra filters isn't just about better indoor air — it’s about investing in farm-driven innovation, renewable materials, and a stronger future for rural America.

Next time you change your filter, you could be doing more than protecting your family’s air — you’re helping expand markets for corn and support a cleaner, more resilient economy.
