Freshness of Pannonhalma in a Refillable Bottle
The Oonly exchange bottles are filled with naturally crystal-clear, velvety, soft-tasting mineral water, straight from Pannonhalma. The exceptional quality mineral water, naturally high in metasilicic acid (33 mg/l) and magnesium (54.5 mg/l), comes from the Oonly mineral water well, 136 meters deep, originating from the Alps' catchment area.
For our body, magnesium is one of the most important minerals, essential for the health of muscles, joints, and bones, while metasilicic acid is cell-regenerating: it promotes the renewal of hair, nails, and skin, and nourishes them.
Oonly benefits not only you but also nature: our innovative system allows us to reuse the bottles before recycling them – thus their lifecycle is much longer than that of single-use PET bottles. You don't have to give up exceptional quality mineral water to be environmentally conscious!
You return it, we refill it!
The Oonly mineral water exchange bottle can be refilled on average 25 times. [1] This means that a single bottle is suitable for consuming up to 37.5 liters of water, and in the case of an exchange bottle, more than 80% less plastic is used over a full lifecycle compared to a single-use PET bottle. Moreover, the carbon footprint of refillable exchange bottles like Oonly is smaller due to multiple uses. [2] Sounds good, right?

How does reuse work in practice?
You also play an important role in the Oonly cycle.
1.) A deposit is charged at the time of purchase - this is the same for both still and sparkling Oonly.
2.) A Kifli courier will collect the empty exchange bottles from you. You decide the fate of the deposit: it can be credited to your account (this is useful if you want to order Oonly again), but Kifli.hu can refund it to you at any time upon request.
3.) Once the bottle is back with us, we disinfect it with our high-temperature, germ-free cleaning process, refill it, and the process starts over.
