BISSELL strives to offer you safe and healthier products to clean up life's messes. And we design all of our products with environmental sustainability in mind. BISSELL's cleaning formulas for portable and upright deep cleaners, as well as most BISSELL sprays and foams, contain biodegradable detergents and have no phosphates, dyes, optical brighteners or heavy metals. Most BISSELL machine formulas carry the EPA's design for the Environment (DfE) certification, which recognizes safer chemistry.
