Water Bottle Filter is made of food-grade, lead-free, and BPA-free materials. Uses 100% selected coconut shell carbon block from Sri Lanka, which ensures maximum filtration and cleaner water. This Water Bottle Filter is compatible with Brita BB06, 060258363241, and most hard-sided water bottles, including New Brita Sport soft-sided water bottles and stainless steel water bottles. (If you are not sure whether your water bottle is compatible, check the replacement filter model number at the bottom of the water bottle.) Enjoy fresh water by replacing your filter every 2 months or after 40 gallons, whichever comes first, depending on water conditions. Each Water Bottle Filter can replace up to 300 standard 16.9-ounce plastic water bottles. This helps reduce plastic waste and supports environmental protection. The Water Bottle Filter is easy to install without any tools. Note that installation methods may differ between hard-sided bottles and sport bottles.
