Sustainability Score

62%

While FilterBuy manufactures domestically and uses some recycled materials, they lack transparency in their environmental reporting and ESG metrics. Their packaging could be more sustainable, and they don't publicly share comprehensive data about their carbon footprint or energy usage. Though they maintain fair labor practices, there's room for improvement in their environmental initiatives and corporate sustainability reporting.
