Thermos brand NSF/ANSI 53 certified filtration bottle reduces contaminants such as: aesthetic chlorine, chloramine, atrazine and particulate class v contaminants, as well as bad tastes and odor, from water. The filter does not reduce fluoride. Achieving an NSF certification assures the product complies with all standard requirements by a well-respected certification organization. Thermos brand NSF/ANSI 53 certified filtration bottle features an innovative gravity-fed filtration method that allows water to pass through the filter naturally, and not by force, giving it increased contact time with the filter, resulting in contaminant-reduced water that is ready to drink.

Made from BPA-free Eastman Tritan polyester material, this 22 ounce bottle features an open spout that allows for great flow rate with no forceful sucking or squeezing required. It also features a hygienic, locking, push button lid with one-handed operation and integrated carrying loop. NSF/ANSI 53 certified filter lasts for approximately 20 gallons (128 full bottles) and is enhanced with DuPont licensed filtration. This thermos brand water filtration product is not designed to purify water. Do not use this bottle with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
