Which bottles will the BUZIO straw lid and filters fit?

• Fits most insulated bottles that have a 2.2‑inch opening

How do the upgraded carbon filters improve water taste and clarity?

The kit includes two 5th‑generation activated carbon filters that have increased surface area for better contact with water. They are optimized to reduce common taste and odor elements like chlorine and other impurities for a cleaner drinking experience when using compatible bottles.

• Natural activated carbon media for improved adsorption
• Larger filter size for longer contact time with water
• Each filter treats up to about 48 gallons (roughly three months typical use)

How easy is it to install and maintain the straw lid and filters?

Installation requires no tools: rinse the new filter, insert it into the straw assembly, and secure the lid to your wide‑mouth bottle. Replacement is straightforward when the filter's service period ends, and all components are dishwasher‑safe on upper racks where applicable.

• Rinse each carbon filter for one minute before first use
• Push the filter into the straw assembly; attach lid to bottle
• Replace filters about every three months or per taste changes
