Wide Compatibility: Our straw lid fits all 2.2-inch wide-mouth insulated cups, including BUZIO models ranging from 22oz to 64oz, and is compatible with other brands like Hydro Flask, Simple Modern, and Yeti.

Upgraded Carbon Filter: Our carbon filters are made from natural activated carbon, featuring the 5th-gen technology with an increased size. They efficiently removes odors, chlorine, and impurities from water, delivering a smoother, cleaner drinking experience.

Safe and Sustainable: Our carbon fliters, lid, and straws are made from BPA-free, food-grade materials. Each filter purifies up to 48 gallons—about 3 months of use—reducing plastic waste by replacing about 300 disposable bottles.

Easy to Use: Our specially designed straws and carbon filters are easy to install and replace. Simply unpack the filter, rinse for a minute, and it's ready to use.

What You Get: 1 x straw lid, 2 x carbon filters, 6 x straws, and the the peace of mind that comes with BUZIO's worry-free after-sales service.
