Every year, hundreds of millions of HVAC filters are discarded — most made from plastics that persist in landfills. Traditional high-efficiency filters improve indoor air quality but also increase energy use and generate plastic waste.
The Braden nATUR™ line solves this problem with an innovative biobased, biodegradable filter media. Built entirely from compostable polymers, nATUR captures fine particles down to sub-micron levels while maintaining low pressure drop and compatibility with legacy HVAC systems
Three-Layer Composite Design:
Layer 1 – Biopolymer Nonwoven: Prefiltration & pleat support.
Layer 2 – Nanofiber Efficiency Layer: Biodegradable nanofiber captures harmful sub-micron particulates without efficiency loss.
Layer 3 – Protective Layer: Light biopolymer layer shields the nano for stable performance during processing and operation.
This structure eliminates the need for wire backing, making the filters easier to process on standard pleating equipment.
MERV 13 & 13A (per ASHRAE 52.2) Efficiency: Verified by independent labs.
Size Range E1 = 53.2%
Size Range E2 = 85.2%
Size Range E3 = 96.3%.
Low Pressure Drop: Designed to maintain airflow and energy efficiency in existing systems.
Durability: Stable pleat geometry and long service life life.
Biobased polymers derived from plant starches.
Biodegradable & compostable under proper conditions.
Carbon sequestration potential if disposed in non-degrading sites.
Reduces plastic waste & microplastic pollution from air filters.
