Solution of the drinking regime with LOKNI in grammar schools

In September, four LOKNI Office filtered water stations were installed in South Bohemia at the J. N. Neumann Bishop's Grammar School. With this initiative, the school addresses the hydration needs of its students, providing free filtered sparkling and still water.

František Křižík Gymnasium and Elementary School in Pilsen has also taken proactive steps to address the hydration needs of its students. Prior to the new school year, the institution unveiled a surprise for its students: two LOKNI Office filtered water stations  providing chilled sparkling and still water. Students can conveniently refill their bottles for free.

testovali jsme novou čtečku

We tested a new scanner

During May and June we tested our new scanner at the University of Economics and Business. You can just place the phone into the scanner and you can start drawing water immediately. Apart from more precise scanning of the QR code you have got one hand free, which was much appreciated by the students. We would like to install the new scanner at most places in September.

Ceremonial opening of LOKNI. The whole TBU drinks for free.

Good news for anybody who likes microfiltered water and at the same time wants help Nature and save unnecessary plastic. Tomas Bata University has got the water filtering device for you. It is called LOKNI  and you can draw either sparkling or still water of the top quality from that. What’s more, the water is FREE for all the users from 6th April.

We would therefore like to invite you to the ceremonial opening that will take place on 6th April. You can meet there the representatives of the school, the operators of BEZPETEK and also people from the LOKNI company. You will enjoy the speeches, get some useful information and taste the still as well as sparkling water.

P.S.: The first 25 people with the LOKNI app will get a glass bottle for a few drinks here and there around the university.

The best waste is the one that does not even come to existence

LOKNI represents an alternative to bottled water and it helps save PET bottles because you can draw the water into your own bottle. One filtration device saves approx. 2.83 tons of plastic per year and the whole LOKNI community has already saved more than 6,500,000 PET bottles.

How does that work?

Students download the LOKNI application, register and choose a tariff in the application – Sponsored TBU. After opening the application there is a QR code that can be easily scanned by the LOKNI scanner and then the students can immediately draw either still or sparkling water for free.

How to use LOKNI? (Video tutorial)

Advantages of drawing with the app?

Everybody has got a perfect overview of their water intake and the daily limit is 3 litres of water. They can see their personal statistics – how many kilograms of plastic they have saved, PET bottles, amount of CO2, which would have come into existence if the bottled water had been transported.

Why to draw from LOKNI?  

Thanks to the complex filtration through the activated carbon filters, LOKNI rids the water of all the undesired tastes and smells and removes all the particles and impurities bigger than 0.2 micron which can be normally found in common tap water. Thanks to the special treatment of the water using the UV light, the device also liquidates the undesired bacteria and microorganisms.

Unfiltered beer into your own bottle!

We have answered the pleas of students and from May on there will be a new type of LOKNI available at universities – NOFILTER.

„Glassmakers, paddlers as well as cyclists all have their light beers but students have been neglected. They also deserve to have beer within their grasp! They will appreciate this wholesome ionic recovery drink namely during the exam period when their performances get heroic. We believe that in this case a lot of PET bottles will be saved as well,“ mentioned Martin Nepil from LOKNI

We want to do a good thing

We became frightened by the amount of PET bottles and bottled water. We decided to try and do something about it and so invented an alternative to bottled water – the filtration device LOKNI. We are dreaming about the world where anybody can draw fresh (sparkling or still) water into their own bottle, anywhere and anytime.


One bottle is enough

When we started 7 years ago, we had no idea how popular LOKNI will become. Nowadays you can find us in tens of schools and companies. At universities we are within the reach of about 100,000 students. The whole LOKNI community has already saved more than 10,000,000 PET bottles. If even this number seems to be too abstract for you, try to imagine for example 200 fully loaded trucks that never started their journey.

It seems unbelievable but every minute a million of PET bottles is sold in the world. However, not even half of them gets recycled...

Our mission

We are doing a good thing not only for people but also for the environment. We would like to build a large network of LOKNI and thus save hundreds of tons of plastic every year. When we teach people to drink healthy water from their own bottles, they will not need to buy bottled water.

The stronger the community connected to LOKNI, the more plastic will be saved.
Thank you for caring about the environment and saving plastic.
