Why Aerterra

At Aerterra, we believe you shouldn't have to choose between performance and sustainability. Our air filters are engineered to protect your home’s air quality—and the planet. Crafted from renewable, plant-based materials, Aerterra filters are a high-performance, eco-forward alternative to conventional, petroleum-based filters.

Performs Where It Counts

Aerterra filters are MERV 11 rated, capturing airborne particles like dust, pollen, pet dander, and mold spores—making them ideal for homes with allergies, kids, or pets. You get the same filtration strength as major brands, without the environmental cost.

Made from Corn, Not Crude

Unlike traditional filters made from synthetic, oil-derived plastics, Aerterra filters are made using PLA—a renewable biopolymer derived from American corn. It’s a smarter use of a homegrown resource that supports sustainable farming and reduces reliance on fossil fuels.
