ÖKO Water Safety

By Country & Region

ÖKO WATER SAFETY BY COUNTRY AND REGION

ÖKO filtered water bottles may be equipped with our level-1 filters for municipal tap water filtration in US and other countries or upgraded to levels-2 or even level-3 filters for outdoor, international use or any environment where stronger water filtration may be required.

Drinking Water Around the World

With a large variety of contaminants and waterborne diseases present in various bodies of water, conditions vary greatly from source to source, and it’s impossible to be sure what’s in your water. Even though running water and tap water are generally considered cleaner and safer to drink, all water that’s piped or from open sources can potentially be contaminated with harmful substances and microbes. Personal judgment should always play an active role when you’re considering whether to drink water from a certain source.

About Our Rating System

Even though our water bottles with filters have been successfully tested for a variety of waterborne microbial agents, we feel that specific claims could mislead users into drinking potentially unsafe waters. Instead, we base our rating system strictly on the availability of safe water in each country. We carefully maintain our water safety rating system using available data on worldwide water conditions compiled from the WHO (World Health Organization), UNICEF, the UNDP (United Nations Development Program), The World Bank, and the (NRDC) National Resources Defense Council. If you live in or are thinking of visiting any country listed on the chart below, note the recommended ÖKO filter for the water conditions in that region.

ÖKO RATING AVAILABLE "Safe" Water(Relative to % of Population) ÖKO RECOMMENDATIONS ÖKO FILTER
••••• 99-100% Generally safe and regularly monitored municipal water in cities and rural areas. Water taste, odor, chlorine and mineral levels may be variable. ÖKO L1 filters are recommended to enhance the flavor of the water and provide extra protection. L1
•••• 96-98% Generally safe piped water, but some water may contain harmful agents —especially in rural areas. ÖKO L2 filters are recommended to protect against variable water quality. L2
••• 93-95% Questionable water quality. Even though locals may be drinking piped water, travelers must use caution and be selective with their choice of water sources in these countries. ÖKO L2 filters are highly recommended to improve water conditions. L2*
•• 89-92% Water deemed generally unsafe for drinking. Biological purification highly recommended. ÖKO custom L3 filters may be available in some countries. L3
• 88% & Below Not rated for ÖKO products. Does not meet potable water standards. All water used by travelers should be adequately treated before drinking. NR*

Every filtered water bottle is not the same. ÖKO water bottle filters come in 3 levels (2 levels available for US retail), so you can use the bottle everyday to reduce chlorine, taste and odor of tap water or switch to a stronger level-2 filter when outdoors or traveling. For more details and the right filter for where you are going, visit our ÖKO & Safe Water page.
