Water concepts as individual as you.
As pioneers in drinking water refinement, we have been creating innovative concepts for refining tap water to the quality and taste of fresh mountain water since 2009. With us, water is being rediscovered as a source of new quality of life and water bottle waste is being reduced. Still and clear, boiling tea water at the touch of a button, chilled or sparkling - with LEOGANT, you can get everything you need straight from your tap. For our individual concepts for natural water refinement, we choose the best components from selected manufacturers and configure them with great attention to detail in Berlin. Get to know water in its most original form and discover our premium water filters - online in our LEOGANT store or in our Berlin showroom!

Natural water treatment for a conscious lifestyle.
Our water concepts combine premium activated carbon filters with effective vitalization technology to create holistic filter systems. Pollutants such as medicines, hormones, pesticides, heavy metals, lead, microplastics and much more are safely removed. Minerals and trace elements remain in the water. This is the only way to give the water a natural and authentic taste. Water enjoyment like from a spring in the mountains. Our holistic concepts for water refinement make a difference that you can feel and, above all, taste.

Frequently asked questions.
Are hormones, medications, heavy metals and microplastics filtered?
Yes. Our German activated carbon filter, which has been tested multiple times, is TÜV-certified and reliably removes unwanted residues and pollutants such as:
Hormones
Medications
Pesticides
Microplastics
Parasites
Lead
Copper
Chlorine
Chemical and organic residues
Does a LEOGANT filter change the TDS/microsims value?
No. The TDS value/µs value cannot provide any information about whether water is healthy or not. Only the conductivity is measured here. Our approach is natural water treatment, so minerals and trace elements remain unchanged in the water. Water with many minerals has a higher TDS value/µs value compared to water with few minerals. In nature, spring waters, depending on their origin, occur in different mineral concentrations, for example calcium, potassium, magnesium and sodium. Therefore, the TDS value/µs value depends on the region in which you live.
Does LEOGANT offer a money-back guarantee?
At LEOGANT, we are absolutely convinced of the quality and performance of our water filters. That's why we want you to share this enthusiasm with us. We are sure that you will also love the water. And not just for a moment, but for many years to come! The positive feedback from our customers confirms our quality and the incomparable taste of LEOGANT water.
For this reason, we offer a 4-week money-back guarantee. Try it out, drink the water, feel the difference and join our community of water fans.
Is a special faucet required for the filter system?
Our filter systems usually require special faucets. An exception is our AVAIO table filter, which is connected directly to your existing faucet. For systems that only supply still water, you can choose between 3-way faucets that replace your current faucet or a separate faucet, which requires an additional hole. The special drinking water faucets ensure convenience and hygiene by separating filtered and normal service water, preventing pollutants from getting back into the water. With our premium filter, which creates a flow rate of 4 liters per minute, the entire cold water can also be filtered in individual cases if you cannot part with your faucet. However, a special faucet is essential for systems with boiling water or sparkling water function, as it controls the devices electronically.
Is limestone also filtered?
No. A LEOGANT filter system is designed to restore the natural balance of the water. Our filter system retains minerals and trace elements in the water, including dissolved lime (calcium carbonate). Dissolved minerals can be metabolized, giving the water its regionally typical taste and stabilizing the pH value.
Lime has various functions in drinking water, such as:
Mineral source: Lime provides calcium
Taste: Lime is an important flavor carrier
Neutralization of acids: Lime is alkaline
However, our revitalization process changes the geometric structure of the lime in the water, so that it no longer adheres as strongly, and the water tastes fresh and soft.
What are the ongoing costs?
According to DIN EN 806, a water filter must be replaced after 6 months at the latest. Therefore, you need 2 filter cartridges per year for our standard filter systems.
One filter cartridge costs 129,- Euro. The follow-up costs are therefore 258,- Euro per year for up to 40,000 liters of water.
Our business concepts for e.g. larger productions, fitness studios or gastronomy can contain up to 4 filter cartridges and the annual costs are correspondingly higher.
How environmentally friendly is a LEOGANT filter system?
LEOGANT stands for sustainability and quality. Our filter systems are not only excellently manufactured, but also designed for longevity. Many of our customers have been using our products for more than a decade. When changing the filter, only the activated carbon cartridge needs to be replaced, and not the entire housing, as with many other providers. The activated carbon cartridge is made of coconut shells, a renewable raw material. The filter systems themselves work without electricity (except for kettles and sparkling water makers) and no waste water is wasted during filtering. This minimizes waste and protects the environment. When you choose LEOGANT, you are not only investing in a durable product and excellent water, but also in a CO2 and plastic neutral company that has environmental protection in its DNA. And of course, you'll reduce waste and water bottles when you use a LEOGANT filter system.
Can I install the filter system myself, or does LEOGANT offer an installation service?
We offer an installation service throughout Germany to ensure that your LEOGANT filter system is installed correctly and hygienically. If you would like to carry out the installation yourself, we supply our systems with all the necessary connection material and installation instructions. Please note, however, that different manual skills are required depending on the system. While you can carry out smaller installations in the private sector, we ask you to pay attention to hygiene and drinking water protection, especially when it comes to drinking water. Always check a few days after installation to make sure everything is really tight. Installations carried out independently are excluded from our liability, so we strongly recommend that laypersons commission a technician. A certified technician is generally required for professional applications.
