Setup and First Use
Before using your AQUAPHOR City Bottle filter for the first time, follow these steps:
- Unpack the Filter: Carefully remove the new filter from its packaging.
- Rinse the Filter: Rinse the filter under cold running tap water for approximately 30 seconds. This helps to remove any loose carbon dust.
- Install the Filter: Insert the rinsed filter firmly into the designated slot within the AQUAPHOR City Bottle lid. Ensure it is securely seated to prevent leaks and ensure proper filtration.
- Fill the Bottle: Fill the bottle with tap water.
- Prime the Filter: Take a few sips of water through the filter. The first few sips may contain some carbon particles; this is normal and harmless. Discard the first full bottle of filtered water to ensure the filter is fully primed.
