At Natural-Breeze we focus on producing Eco-friendly products that our customers love and will reuse over and over again. We are an innovative driven company, continually looking for new ways to improve our products! Our filters are designed from a synthetic polymer known as Dura-Ester. This is a durable material that allows customers to rejuvenate their filters simply by washing them with cold water. Our focus is providing families with an inexpensive solution to putting humidity back into their homes.
