Frequently Asked Questions
How often do I change my ÖKO filter?
The lifespan of your filter greatly depends on the quality of the water you filter through it. The more contaminated the water, the shorter the life of the filter. We suggest you change it every 50 gallons for best tasting water, but it should be fine for up to 100 gallons with most tap water.
Based on 100 gallons of water, you will get:
- ÖKO-550 (0.55L) Small Bottle – 750 Refills
- ÖKO-650 (0.65L) Adult Bottle – 580 Refills
- ÖKO- 1000 (1L) Jumbo Bottle – 375 Refills
How do I know its time to change the filter?
As a general rule, if water does not look clear, taste clean or if the flow seems to be slower than usual, the filter should be replaced.
How can I tell if I have a level-1 or level-2 filter?
If you purchased your bottle on January 2013 and onwards, check the color of the silicone ring on top of your filter. Red means you have a level-I filter and clear means you have a level-II filter.
Will my ÖKO filter fit in other ÖKO bottles?
ÖKO filters work with all ÖKO bottles regardless of size and color. Note: This does not include the ÖKOPURE product.
Can I drink juice, coffee or tea from my bottle?
ÖKO bottles are designed for filtering and drinking water. You can use the bottle without the filter to drink juices or your favorite drinks, but it is not recommended for hot beverages. Make sure to rinse the bottle thoroughly before you use it again with the ÖKO filter. Juices or beverages other than water damage the filters.
What happens if I use my ÖKO bottle and filter for drinking juices?
Sugar, salt and other substances present in juices, tea and other beverages clog up the filter quickly and will damage it permanently.
How do I clean my ÖKO filter?
You shouldn’t! Unlike basic, simple carbon filters, the ÖKO filter media is made of a high-performance and sensitive material. Subjecting the filter to harsh detergents or soapy or hot water will not only loosen its pores and reduce its performance level but may impair its function permanently.
How do I clean my bottle?
Depending on how hot your dishwasher gets, the bottle is machine washable. NOTE: the filter is NOT machine washable and will be permanently damaged if put through a dishwasher. To extend the life of your water bottle, we recommend washing by hand to avoid potential damage, especially to the threads that screw the cap on. To wash the water bottle, remove the cap (and the filter), place in dishwasher top rack, or use lukewarm water and light detergent. Rinse thoroughly. Repeat if needed.
Can I wash the bottle cap?
Yes. To do this, you should disconnect the filter and Ö-ring carabiner, hand-wash the cap with mild detergent. Be careful that the seal inside the cap does not slip out. If the silicone seal slips out during the wash, follow these steps:
- Carefully place the seal back into the cap. Be sure it stays flat.
- Put the cap onto the bottle and close tightly to secure the seal
If you notice a leak from the bottle when drinking, repeat steps 1 and 2.
What happens if the seal from the cap comes off?
In rare occasions the seal in the bottle cap may slide out due to excess pressure and vacuum created when closing the bottle. Should this occur, please write to us from the Contact ÖKO page for instructions on re-installing the seal.
What if my bottle is defective?
You may return a defective product to us for replacement within 30 days of purchase. Please use the Contact ÖKO link for further instructions. Due to the nature of the product and health and hygiene issues, we do not offer refunds.
