The OKO water filter bottle is reusable, BPA free and portable giving you the freedom to enjoy filtered water wherever you go.

The OKO water filter is a state-of-the art Level II advanced filter originally designed by NASA for use in space stations. ÖKO level-2 filter lab tests reflect removal of 99.994% of e-coli, 99.9999% of cryptosporidium and giardia lamblia, the most commonly found bacteria and microorganisms in lakes, streams and international water sources. A stack of over 400 such pores in the 0.8mm thickness of the filter create a “tortuous path” which a harmful agent would have to travel through in order to make it across the filter membrane.

It is an ideal choice for everyday use, travellers, adventurers, hikers, yogis, runners, and anyone who needs convenient access to clean, clear, crisp water. Suitable for use in over 140 countries worldwide.

Please note: replacement filters are only available for online purchase and not in our Brisbane stores.
