The deeper pleats of the filter offer lower pressure drop, less strain on HVAC equipment, and much longer filter life!

Sustainability Score

62%

While the company offers products that promote water conservation and air quality, their corporate sustainability practices show room for improvement. They provide limited transparency about their supply chain and manufacturing processes. Their recycling program for used filters is commendable, but packaging could be more eco-friendly. Labor practices and worker conditions in manufacturing facilities lack detailed public documentation. The company has made some progress in reducing their carbon footprint but falls short of industry leaders in environmental commitments.
