Regular cleaning and proper maintenance are essential to ensure the long-term performance and hygiene of your ÖKO Filter Bottle. This guide outlines how to care for your ÖKO bottle and both filter types—Level-2 and Level-3—to keep your water clean, safe, and great-tasting.
Bottle Cleaning
Your ÖKO bottle is made from durable, food-grade materials that are BPA- and phthalate-free. To keep it fresh and ready for use:
How to Clean the Bottle:
- Frequency: After every few uses or whenever needed
- Method:
- Hand wash with warm water and mild dish soap
- Use a bottle brush for thorough interior cleaning
Rinse well to remove all soap residue
Important: Remove the filter before cleaning the bottle
Dishwasher Safe?
No — The bottle is not dishwasher safe to preserve material integrity and filter compatibility
ÖKO Level-2 Filter Maintenance
The Level-2 Filter uses advanced electro-adsorbent nano-filtration and is designed for high-efficiency daily use. To keep it functioning at peak performance:
Regular Maintenance:
- Never use soap, hot water, or detergents on the filter
- If flow decreases, gently rinse the filter exterior with clean water to remove sediment or buildup
- Let the filter air-dry completely before reinstalling, if not used regularly
When to Replace:
- After filtering 380 liters (100 gallons), or approximately every 3–4 months
- When you notice reduced water flow, indicating filter clogging
- If you’ve used the filter with water containing high sediment levels, consider replacing it sooner
Tip: A slight dark tint in the water during first use is harmless carbon residue—flush it by squeezing clean water through the filter.
ÖKO Level-3 Filter Maintenance
The Level-3 Filter uses a 0.1-micron hollow fiber membrane designed for rugged conditions and extreme filtration. With proper care, it can last up to 3,000 liters.
Regular Maintenance:
- After use, rinse the filter thoroughly with clean water—especially if used with murky or sediment-heavy water
- Store in a dry, cool place
- Do not use soap, hot water, or dishwashers, as these will damage the membrane
When to Replace:
- After 1,000 liters of use under normal conditions, or up to 3,000 liters with regular rinsing
- If you experience significant flow reduction, it's likely time for a replacement
Direct Suction Users:
If you're using the Level-3 filter as a straw (outside of the bottle), be sure to:
- Blow out residual water after use
- Keep the straw and adapter clean with warm water rinses
General Care Reminders
- Do not expose any filter to freezing temperatures or high heat—this can damage the filtration membranes
- Never use bleach, vinegar, or alcohol on filters
- Do not use filters with saltwater or chemically contaminated water (e.g., industrial runoff)
