Frequently Asked
Questions
What's the benefit of a squeezable plastic bottle?
We use soft plastic because it's the only material that delivers everything outdoor enthusiasts need: ultralight weight for long-distance hiking, impact resistance for rugged adventures, and the flexibility required for our FilterSure™ technology that provides fast, natural water flow.
How often do I change my ÖKO Original 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-750 (0.75L) Adult Bottle – 580 Refills
- ÖKO- 1000 (1L) Jumbo Bottle – 375 Refills
How do I clean my ÖKO filter?
Don'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, soapy or hot water will not only loosen its pores and reduce its performance level but may impair its function permanently.
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.
