Does Flaska contain BPA?

Flaska is made of glass and contains no BPA. Glass is the best material for storing water as it does not leach any toxic substances.

Where is Flaska produced?

Flaska is a Slovenian product. The glass bottles are produced in Italy while the final production phases (including programming) are carried out at Zgoša near Begunje in Slovenia.

Does the Flaska bottle cap provide a good seal?

The Flaska bottle cap provides the perfect seal. In case of wear or if it is destroyed or lost please e-mail us at water@flaska.eu and we will send you a new one.

What material is the bottle cap made of?

The bottle cap is made of Expancork, which has obtained all the necessary certification for contact with food. For Cork Flaska models, the bottle cap is made of natural cork.

How to clean Flaska?

Do not wash Flaska in a dishwasher. Clean it using a regular bottle brush and kitchen detergents (if needed). We recommend using an eco-detergent.

Can Flaska be used for the consumption of juices or other beverages?

It can. Here at Flaska company, we promote the consumption of water. However, Flaska can also be used to consume juices, tea etc.

There are signs of scale on my Flaska. What to do?

Pour into the bottle one part vinegar and two parts water. Leave overnight and the scale will decompose.

Is Flaska suitable both for hot and cold beverages?

It is. The water vibrational structuring process never stops and the glass is robust and will not break. However, do not pour boiling water into Flaska.

How should I put on/take off Flaska’s protective neoprene sleeve?

If you take the neoprene protective sleeve off the Flaska in the wrong way, the “ears” may start to tear. See how to correctly put on/take off the protective neoprene sleeve in this short video.

How should I put on/take off Flaska’s protective silicone sleeve?

The easiest was to put on/take off the silicone protective sleeve is to make Flaska wet. See the short video How should I put on/take off Flaska’s protective silicone sleeve?

Is Flaska also suitable for fizzy drinks?

Because the Flaska bottle cap is in a form of a plug, the bottle is not suitable for fizzy drinks as the cap could be forced off the bottle.

I have lost my bottle cap. What to do?

Go to the accessories page of the Webshop there you will find replacement tops for all of the Flaska Products. 

The protective sleeve has torn. What can I do?

In our online shop, you will find alternative protective sleeves for all Flaska models.

How should I remove a broken cork cap from my Flaska?

Questions on water structuring

What is water structuring?

Water structuring, which happens inside Flaska, is the modifying of water’s vibrational structure to bring it closer to spring water.

What is glass programming?

Glass programming is a process composed of four phases. The most important is the TPS phase (technology of programming silicone). Read more about glass programming

Which or what kind of information is stored in the glass?

We use a programme consisting of various kinds of information from nature. This information is selected and harmonized with the aim of restoring the water’s original vibrational state.

Are you in possession of certificates which substantiate these assertions?

Tests which directly substantiate these statements may be accessed here.

How long does it take for the water’s structure to change?

The vibrational structuring of water begins immediately after the water is poured into Flaska – wait at least 5 minutes to ensure the full effect.

For how long does Flaska structure the water?

Flaška d.o.o. guarantees its products bought after 1.1.2019 will be fully efficient and will structure water during their whole lifespan.

Is the structure of the water from the Flaska destroyed if we boil it?

Energy-intensive processes, such as boiling, actually destroy the structure of the water from the Flaska. That is why we suggest making the tea first and then pouring it (but not boiling) into the Flaska.

What is the seal imprinted on the bottom of the bottle?

The trademark on the bottom of the bottle, or cosmogram, has been designed specifically for Flaska by the Slovene geomancer Robi Lavin. The cosmogram protects the glass programme from malevolent influences.

eFlaska - water structuring app

How does the eFlaska app structure the water?

The app works similarly to a common radio. The radio station (A) is broadcasting music all the time. When a person turns on his radio far away and tunes the frequency (B) he can hear music, good news, bad news, etc and this influences his mood (C). Similarly, our device Quantec is broadcasting water restructuring frequencies all the time (A). When a person opens the app, picks up the vibrational program and starts it (B), this program is influencing/programming water on picture (C). For an even deeper understanding of the mechanism behind an app, we advise you to read a trilogy of Tom Cambell My big TOE.

Is Flaska bottle more efficient than the eFlaska app?

We recommend Flaska for easy water structuring for daily use. For special vibration programmes or purposes, we recommend eFlaska.


Flaska and eFlaska complement each other.

What is the difference between Flaska water and water structured with the eFlaska app?

Flaska water has a universal spring structure, suitable for daily drinking in all circumstances. The eFlaska programmes are aimed at specific purpose areas and each user can choose what he or she wants.

Does the eFlaska app eliminate harmful substances from the water?

Like Flaska, eFlaska also neutralizes potential harmful substances in the water to the highest possible extent. One water to another water is different and it is not possible to talk about exact numbers.

Can I also structure other drinks and beverages, for example, alcohol, coffee, tea, or smoothie?

Of course. Pay attention to the changes in taste. For example it is easier to detect changes with lemonade than just water.

Can I use the app only for myself or also for family and friends?

The app works for the person activating it. If your friend wants structured water, you cannot activate the app for him or her, but you need to lend them a phone and they activate it themselves.

What happens if I take photo of a friend and start a structuring process?

Nothing. The app is made in such a way that it does not affect people and does not interfere with their free will.

Does the success of structuring depend on the amount/volume of water?

The app is intended for personal use. Structuring of a lake, for example, will be inefficient. However, we recommend the structuring of your home Jacuzzi.

How much water can I structure at a time?

As much as you reasonably need for personal use. 

How long does the water remain structured in a glass?

Maximum 1 day. 

Can we also use the app to structure water in a plastic bottle?

Of course. In general, the use of plastic bottles is not recommended and we recommend using a classic Flaska or other reusable glass bottles. However, if the use of a plastic bottle cannot be avoided, the eFlaska app is the right thing to have the best possible structured water.

I’m a little confused about how to use an app.

Please check our YT video https://www.youtube.com/watch?v=f5HScLjC1bM

Unfortunately, we can't embed video into the app.

Doesn't the EMF from a cell phone's wireless signal that it is broadcasting interfere with or negatively affect the structuring of the water?

EMF from cell phones can't negatively affect the structuring of the water. EMF from the phone which is in passive mode is very weak. There could be an influence on water, if we would leave the phone on, talk with somebody over the speaker for a long time and have a glass of water very close by. But that is something that nobody is doing, when we structure the water, we are concentrated on the procedure and not talking over the phone.

Can the app really structure all the water in a swimming pool?

The app can't structure the water in the swimming pool. Firstly, the body of water is too big. Secondly, there are (usually) other people in the pool. The app can't work for other people without them knowing about it.

If you take a pic of the water coming out of the shower head, the water is always new. Different water is coming out of the shower head, so anything that was structured would already be down the drain. How does the app work with shower?

The shower is tricky because is different from other functionalities, water is not in a container but flowing. Here it is not so much about the water flowing through the shower, but about programming the place, where a person using an app is having a shower.


Programming is done by the eFlaska app AND a person triggering it.

What difference does it make if the water is structured for pets/plants as opposed to people?

The vibrational program for the Flaska bottle is universal because it has to be efficient for young and old, women and men, for people from different places plus it is used for plants and animals as well. With an app, vibrational programs can be more focused, with an intention to bring the best-structured water for each specific group with their needs.
