We are dreaming about the world without PET bottles
We became terrified by the amount of PET bottles and bottled water. We decided to do something about it and therefore we invented a perfect alternative to that – LOKNI. We are dreaming about the world where anybody can draw fresh sparkling or still water into their bottle, anywhere and anytime.

8 good reasons
why to drink with LOKNI

Better taste
LOKNI filters the water, which means it rids the water of bacteria, impurities and microplastics (bigger than 0.5 nm), chlorine as well as potential smells.

Cheaper than the bottled one
The price is always favourable, for 1 CZK you can get up to 3 litres of water. With the sponsored tariffs it is for free.

100% care
We take good care of the LOKNI network. We regularly exchange the filters and sanitize the devices.

Wide network
The completely installed network will offer more than 120 filtration devices all over the Czech Republic. However, that is not the end of the story.

Fresh and healthy water
Sparkling or still – our water fulfils the criteria of the National Institute for Public Health.

Saving plastic
When drawing water into your own bottle you help Nature. Together we have helped to save 7 million PET bottles. One device saves about 2 830 kilograms of plastic per year.

Water in motion
LOKNI is connected to the water mains and so the water does not stay in it.

LOKNI app
Thanks to the application you get an overview of your water intake as well as of the saved plastic. You will be pleased by the personal as well as community statistics. You can download it from Google Play or App Store.
