Thermal Filter Bottle dafi SOLID Steel COLD 500 ml — insulated water bottle with built-in filter, blue

Dafi SOLID Steel COLD 500 ml is an insulated water bottle with an integrated filter, designed to provide cooled, filtered drinking water while on the move. The bottle combines a vacuum-insulated stainless steel body with a built-in filtration element to reduce impurities and deliver a steady chilled temperature for liquids. With a 500 ml capacity and a screw-top lid, this blue bottle is intended for everyday travel, commuting, sports and short trips where filtered and temperature-stable water is preferred.

Advantages

The double-wall vacuum insulation keeps liquids cool for extended periods without external condensation, while the stainless steel construction offers durability and resistance to impacts and odors. The built-in filter reduces common contaminants and improves taste without requiring a separate filtration device. The ergonomic shape and 500 ml size make the bottle easy to carry and store in backpacks, bike cages or car holders.

How to use

Rinse the bottle and the filter element before first use according to the manufacturer’s care instructions.

For best thermal performance, pre-chill the bottle or add chilled water and keep the lid closed between uses. Disassemble the lid and filter when cleaning and allow all parts to dry completely before reassembly.

Usage recommendations

Replace or service the filter element as recommended by the manufacturer to maintain filtration effectiveness. Avoid using the bottle for acidic or carbonated beverages that may affect the filter or sealing components. Hand wash recommended for the lid and filter components; the stainless steel body can be rinsed and wiped dry to preserve insulation performance.
