Eco-Air refills outperform gels, wicks, and aerosols using unique fragrances that are designed for consistent and powerful 30-day performance. The Eco-Air is freshness made simple. The refill is a solid that has been infused with natural fragrance oils so the air you breathe is chemical-free and there's no messy gels or liquids. Eco-Air works great in conference rooms and entryways, in restrooms and trash rooms. Simply mount it on the wall near a door so the natural airflow can spread the fragrance throughout the space. Built with sustainability in mind, Eco-Air refills are part of Fresh Product's closed-loop recycling program and are 100% recyclable.
