2. Setup
Follow these steps to prepare your Aqua Optima Oria Water Filter Jug for first use:
- Unpack and Clean: Carefully remove all components from the packaging. Wash the jug, lid, and hopper (the inner funnel) with warm, soapy water. Rinse thoroughly and dry. The jug is dishwasher friendly for convenience.
- Prepare the Filter: Remove the Aqua Optima Evolve+ filter cartridge from its packaging. Submerge the filter completely in cold water for approximately 5 minutes to remove any air bubbles.
- Install the Filter: Insert the prepared filter cartridge firmly into the opening at the bottom of the hopper. Ensure it is securely seated using the 'Bayonet Fit' feature for optimal performance.
- Assemble the Jug: Place the hopper with the installed filter into the jug. Ensure it sits correctly.
- Initial Filtration: Fill the hopper with cold tap water. Allow the water to filter through. Discard the first two filtered batches of water. This primes the filter and removes any loose carbon particles. Your jug is now ready for use.

3. Operating Instructions
Using your Aqua Optima Oria Water Filter Jug is simple:
- Filling: Open the slotted lid and place the jug under a cold tap. The 'pour through' lid allows for easy and instant filling without removing the entire lid.
- Filtration: The water will pass through the Evolve+ filter cartridge via fast flow filtration. The filtered water collects in the main jug reservoir. The jug has a filtered water capacity of 1.4 litres and a total capacity of 2.8 litres.
- Serving: Once filtered, pour the clean water from the jug as needed.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your water filter jug:
- Cleaning: Wash the jug, lid, and hopper regularly with warm, soapy water. The jug is dishwasher friendly. For stubborn limescale buildup, a limescale remover can be used.
- Filter Replacement: The Aqua Optima Evolve+ filter cartridge should be replaced every 30 days or after filtering 100 litres of water, whichever comes first. This ensures continued effective filtration.
- Filter Recycling: All Aqua Optima water filter cartridges are 100% recyclable. Participate in the free recycling program with Teracycle in the UK and EIRE. Visit the Aqua Optima website for details on local community collection points or how to send filters back directly.

5. Troubleshooting
If you encounter any issues with your Aqua Optima Oria Water Filter Jug, refer to the following common problems and solutions:
- Slow Filtration:
Cause: The filter cartridge may be clogged or nearing the end of its lifespan.
Solution: Ensure the filter was properly primed (submerged in water before first use). If the issue persists, replace the filter cartridge. - Water Taste/Odor:
Cause: The filter cartridge may need replacement, or the jug itself requires cleaning.
Solution: Replace the filter cartridge. Thoroughly clean the jug, lid, and hopper. - Water Leaking from Lid/Hopper when Pouring:
Cause: The filter cartridge may not be seated correctly in the hopper, or the hopper itself is not properly positioned in the jug.
Solution: Remove the hopper and filter. Re-insert the filter firmly into the hopper, ensuring the 'Bayonet Fit' is secure. Then, re-position the hopper correctly within the jug. Ensure the lid is also properly aligned. - Limescale Buildup on Jug:
Cause: Hard water deposits over time.
Solution: Clean the jug regularly with warm, soapy water. For stubborn deposits, use a descaling solution or a mixture of vinegar and water.
