What types of contaminants can potentially show up in my tap water?
In many parts of the world, tap water is increasingly contaminated with the following substances:
- Bacteria and viruses
- Drugs and hormones
- Pesticides and herbicides
- Toxic heavy metals
- Volatile organic compounds
Do note that this is not an exhaustive list. For more details, read these blog articles on Tap water: Do you know what’s in your drinking water? and The microplastics threat and what we’re doing about it.
Why do I need a water purification system at home?
Before tap water is delivered to your house, the public water system treats it in an effort to remove chemicals, particles, and bacteria. They do not always succeed as some contaminants are particularly hard to eliminate, such as pharmaceuticals, BPAs, hormones, and microplastics.
In addition, even if some substances do get removed by public water treatment systems, this doesn’t mean your water is completely pure, only that the levels of any present contaminants don’t pose any serious, immediate health risk.
Furthermore, the municipal water is only guaranteed until the point of entry to your house, so there are still possibilities for drinking water to be contaminated despite regulations and water quality standards. For instance, if the pipes in your house are contaminated or made of lead, the water that was previously clean will be contaminated due to leaching again.
Thus, it is best to take your drinking water quality into your own hands, control your drinking water, so you can know for sure that you are drinking safe and healthy water*.
How effective is Mitte in removing pollutants from tap water?
Mitte uses our proprietary distillation technology that is inspired from the natural water cycle to purify tap water. We remove contaminants such as bacteria, viruses, organic and inorganic compounds, pesticides, pharmaceuticals, hormones, microplastics and more.
Used by the World Health Organization as an indication of water quality, we refer to the Total Dissolved Solids (TDS) present in water. It is the total amount of mobile charged ions – minerals, salts or metals – that are dissolved in a given volume of water, expressed as parts per million (ppm). The smaller the TDS value, the purer the water.
To benchmark mitte’s performance, tap water has an average TDS value of 350 ppm while pure, distilled water is at 1 ppm. After purification, Mitte water has a TDS value of 3 ppm.
How is Mitte different from other water purifiers in the market?
1. Purity of water
Our distillation technology stands out from the crowd because of its high performance and efficiency. We provide water that is 60X cleaner than simple filtration and 5X cleaner than reverse osmosis systems. No parts of the machine allows for contaminants to re-enter the water.
2. Personalized enhancement
Other solutions remove both harmful contaminants and beneficial minerals in water via their “catch-all” purification process, while Mitte does not just purify water; we also enhance it with natural minerals that are essential for health. There are different mineral cartridge options available, with varying levels of different minerals that you can pick for your needs and lifestyle.
3. Long-term consistency
Our foolproof machine and fail-safe mechanisms also ensure consistent performance over time. For example, if a membrane in a reverse osmosis system is damaged, the user has no way of knowing about that even though the water quality is impaired. Mitte, on the other hand, constantly monitors the quality of the water that it produces via our built-in sensors. If one part of the machine breaks down, there will be no water output at all to ensure your safety.
4. Smart and connected
The mitte machine is part of a connected ecosystem that can be synced up with our mobile app to further improve user experience and give you more control over the water that you drink.
5. Energy efficiency
Due to our patented water purification technology, we are also the most energy efficient countertop distiller in the market.
What’s the difference between bottled water and Mitte water?
Typically, bottled mineral water contains health benefits because of its rich mineral compositions. However, due to regulations limiting treatment to bottled water, we cannot be fully certain that it is clean or safe. In fact, bottled water is less regulated than tap water.
So by first purifying tap water and enriching it with minerals afterwards, you can be certain that Mitte water is both safe and healthy*.
How do I personalize the water that is dispensed from the machine?
We offer three different types of mineral cartridges with varying mineral ingredients and mineralization levels, allowing you to personalize and create mineral water that suits your lifestyle and taste. They are:
- Mitte Balance – A soft water with a balanced neutral taste and zero sodium, Mitte Balance is an everyday water, perfect for baby food preparation and tea or coffee brewing.
- Mitte Vitality – A crisp drinking water with a high mineral content and complex flavor profile, Mitte Vitality is great for those looking to benefit from essential minerals for improved physical and mental performance.
- Mitte Alkaline – A high-PH water rich in minerals and antioxidants, Mitte Alkaline helps combat acidity and fights free radicals in your body. It also eases recovery after intense physical activities, leading to increased energy levels and better health.
You can check out this page for more information on our mineral cartridges.
What minerals are there in the cartridges and what are they good for?
Each mineral cartridge comes with different mineral types and levels, you may refer to the compositions, ingredients and health benefits of each cartridge on this page: https://mitte.co/personalize-your-water/
What minerals in water can contribute to dietary nutrition?
These are some of the top important dietary minerals in the diet and water that are essential for nutrition and wellbeing (taken from this blog article):
|Mineral||Its functions||Deficiency symptoms||Benefits in water|
|Iron||Iron is necessary for normal body functions such as oxygen transport, metabolism of neurotransmitters, and DNA synthesis.||Impaired mental and motor development and altered behavior.||Significant when dietary intake of iron is low.|
|Zinc||Zinc is required for growth, normal development, DNA synthesis, immunity, and sensory functions.||Growth retardation, delayed sexual and skeletal maturation, and impaired resistance to infections.||Significant when dietary intake of zinc is low.|
|Copper||Copper is responsible for infant growth, host defence mechanisms, bone strength, red and white cell maturation, iron transport and brain development.||Anaemia, neutropenia, and bone abnormalities are the main manifestations of copper deficiency.||Significant for most of the population.|
|Calcium||Besides being the primary structural constituent of the skeleton, calcium is also important for the regulation of enzymes and hormonal responses, blood clotting, nerve transmission, and muscle contraction/ relaxation.||Calcium deficiency leads to a decrease in bone mineral content and mass, leading to increased risk for bone fractures.||Significant for most of the population.|
|Magnesium||Magnesium is essential for the mineralisation and development of the skeleton, and also plays a role in cellular permeability and neuromuscular excitability.||Deficiency of magnesium has been implicated in hypertension and type II diabetes, while low magnesium intake has been associated with an increased risk of cardiovascular diseases.||Significant for most of the population.|
|Sodium||Sodium helps control blood pressure and electrolyte balance, and regulates the function of muscles and nerves.||Cramps, weakness, confusion and seizures.||Minimal, as sodium levels in drinking water are minimal compared with those in the diet.|
|Potassium||Potassium is crucial to heart function and plays a key role in skeletal and smooth muscle contraction, making it important for normal digestive and muscular function.||Muscle weakness, cramping, diarrhoea or vomiting.||Significant when dietary intake of potassium is low.|
What are the sources of ingredients for the mineral cartridges?
We take the greatest care to make sure that the best ingredients are used. First and foremost, we are only using ingredients that are FDA (Food and Drug Administration in US) approved and are certain and certified to not include any harmful substances.
For sourcing and quality control we have been working with Doehler, one of the world’s largest natural ingredient provider based in Germany. Doehler has over 500 food scientists and nutritionists. In addition, we have been working with great institutes and laboratories in Germany (e.g. Institute Kirchhoff in Berlin) to make sure that our products reach the quality we strive for.
To make sure that our machine and cartridges also comply with microbiological risks (e.g. fungi and bacteria growth) we are also working with a laboratory in Barcelona focused on such long term tests.
This is also complemented by self testing at the microbiological laboratories at our manufacturing partner in Taiwan.
The safety of our cartridges will also be visible and accounted for by a voluntary NSF certification, which is based on rigorous testing.
Can Mitte be used without a mineral cartridge?
Based on resources such as this report from the World Health Organization, drinking distilled water could potentially pose major risks for your health. This is also the reason why in Germany, all distilled water sold in bottles come with a warning on the label, stating that it is “Not suitable as drinking water!” (direct translation). At Mitte, we strongly believe that healthy water* is not just pure, but also enriched with essential minerals, and this cascades down to all aspects of our solution. Thus, the mineral cartridge is required for Mitte to do its job.
Which cartridge should I choose?
All three mineral cartridges are designed to give you the best experience with water, and they are all suitable for everyday use. You should choose a mineral cartridge based on your health, lifestyle, and taste preference. For example, if you lead an active lifestyle, go for the Vitality cartridge that helps to hydrate and recover electrolytes quickly. If you have a baby, choose the Balance cartridge for preparing baby formula, as it is the safest option for babies’ digestive systems. And if you’d like to restore pH balance in your body and drink water with antioxidant properties, go for our Alkaline cartridge.
How often do I need to replace the mineral cartridge?
Each mineral cartridge is good for mineralizing 250 liters (almost 66 gallons) of water. Thus the cartridge lifetime depends on how much water your household consumes. For example, if each person in a two-person household consumes 2 liters of Mitte water per day, the cartridge will last about two months.
How do I know when my mineral cartridge lifetime is up?
You will be notified by both the LEDs on the machine and the Mitte app when your mineral cartridge needs replacement.
If I don’t finish a cartridge in one go, can I use it again at later? What is the expiry date of a cartridge?
You can use the cartridges for up to 6 months after the first use. Mitte will detect if the cartridge that you have hasn’t been used in a long time, and it will automatically trigger a flush of the first round of water (it will go directly to the waste tank). This is to ensure that you always drink the freshest and healthiest water possible. Also, if a cartridge is expired, you will get an LED notification on the machine and also a notification in your app indicating that your cartridge needs to be replaced with a new one.
How do I buy a new mineral cartridge?
You can set up demand-driven automatic ordering of mineral cartridges on your Mitte app. Each cartridge comes with an RFID tag, allowing the system to track usage, and automatically deliver you a new cartridge when your current one is running low. The process is based on actual usage, thus reducing wastage while ensuring that you’ll never run out of water. Otherwise, cartridges can also be purchased individually in our webstore.
How does this automatic ordering feature work?
Sensors inside Mitte monitor cartridge life so a new one will be delivered to your doorstep via automatic ordering (on the app) just before the current one runs out.
As the automatic ordering process is based on actual usage, you’ll only receive a new cartridge when you actually need it. You can change, pause and cancel your subscription anytime.
Can I purchase mineral cartridges without signing up for automatic ordering?
Yes, you can purchase mineral cartridges individually in our webstore without signing up for automatic ordering.
What are the machine dimensions?
How much water does Mitte provide at any time?
Mitte uses our proprietary purification method based on distillation, which removes more contaminants from water than any other methods, with more consistent performance in the long term. Thus, the purification process takes some time. The machine purifies one liter of water every two hours (with a maximum purification rate of 12 liters or about 3 gallons per day).
The purification process is always ongoing (unless the storage tank is full) to ensure a ready supply of drinking water.
With smart sensors in the system, the machine and app will also remind you to refill the input water tank when needed, so that the purification process can always be carried out as soon as there is space available in the four-liter storage tank.
How much energy does Mitte consume?
Mitte is designed to be very energy efficient. It consumes on average 0.12kWh while purifying. Since one liter takes 2 hours to be produced, the total energy consumption of the machine for the production of 1l of mitte water is 0.24kWh.
(Please take into account that this is calculated for the typical use case, and that the actual energy consumption can slightly vary depending on your ambient conditions.)
What is the difference between the plumbed-in machine and the non-plumbed-in version?
Both versions work exactly the same in terms of purifying and enhancing water.
The only difference is that the plumbed-in Mitte is constantly connected to your main water line so you will not have to refill the input water tank and empty the waste tank over time; these processes happen automatically. You will most likely have to drill a hole into your kitchen countertop to install this version. Our optional plumbed in kit will contain all the parts necessary to set it up.
On the other hand, setting up the non plumbed-in version is more straightforward. You just need to set it upon your counter and plug the machine into a power socket. Simple! You will, however, have to refill tap water and empty waste water manually as and when it’s needed.
How should I clean and maintain Mitte?
Maintenance includes wiping the storage and input water tanks with a cloth and adding salt from time to time just like you would for a dishwasher. We have an automatic resin regeneration feature that softens the input water before reaching the distillation stage, reducing the possibility of limescale forming on the unit. So all you’ll have to do is to add salt for machine maintenance without having to acid descale your Mitte with descalers or cleaning agents.
You will be notified by the LEDs on the machine and in the app when it’s time to do so. We are still running long term tests to determine how frequently that needs to be done, and in what quantities. More details will follow. This information will definitely be included in your usual manual as well.
What type of materials are used in the production of Mitte?
We have chosen our materials carefully based on quality, costs, manufacturability and of course safety. The plastics that we are using are high grade food grade like PP, and do not leach unhealthy compounds into the water. The heating parts consist of stainless steel 316 and high grade food grade aluminium.
Can Mitte work without internet connection?
Not connecting your Mitte to the internet won’t prevent you from using basic functions such as dispensing water. The system is designed so that you don’t need the app to use the machine.
However, we’d strongly encourage you to take full advantage of this is connected device. The hardware in itself has all the basic functions you need to operate the machine, but using it with the app gives you extra features and the best user experience. For example, you can choose the exact volume of water you want to dispense, check the quality of water, monitor machine performance, receive maintenance notifications, and get support while setting up the system.
Why do I need the Mitte app?
The mitte app gives you more functionalities and control over the machine. For example:
- It sends you reminders when the machine needs some kind of maintenance.
- You can set up automatic cartridge ordering, allowing you to receive mineral cartridges based on usage. So you get fresh new cartridges just when you need them, only when you need them.
- You can actively monitor the machine when you are not home and check the water quality in real time, giving you a peace of mind.
- It tracks the amount of water dispensed from the machine, and consequently, the amount of water donated to the developing world via our partner, Water.Org.
Why is Mitte connected to the internet?
Connecting Mitte to the internet allows you to use extra features offered in the app, such as the automatic ordering of cartridges that ensure you’ll never run out of water and tracking your own personal social impact based on usage.
Why am I automatically donating water to a developing country?
We developed a 1-for-1 program based on our guiding vision of improving life with better water.
Right now, 159 million people in the world are getting water from untreated surface runoff and streams. A further 663 million people lack any access to safe water. With our 1-for-1 guarantee, we want to help change some of these shocking figures and tangibly improve more lives with better water.
We have designed Mitte so that it tracks usage and every time you dispense a liter of water, a donation to a water project in developing countries is made. We are making you the promise that for every liter of Mitte water you drink, someone in need will get his yearly requirement of clean water too. This happens automatically and is built in. You are not paying any extra money for this project, and no extra action is needed on your part.
Why can I not choose to whom and how much I am donating?
With our NGO partner, Water.Org, we have selected the project that can generate maximum positive social impact, to truly realise the vision of improving lives with better water.
When will you start shipping Mitte?
We are moving to production stage right now and will be shipping in June 2019.
We have been working on Mitte for over two years to create a connected eco-system: our hardware, app, mineral cartridges, and cloud back-end. Mitte is currently moving from prototype stage towards ready-for-mass-production with our manufacturing partner.
The mass manufacturing process goes like this until shipping:
– Enter product specification discussion
– Carry out detailed optimization of machine design and structure for mass manufacture
– Review outcome of design, finalize and order parts for next stage
Prototyping and tooling:
– Build 1 prototype based on DFM process outcome so as to confirm that the design matches the specification
– Craft 2D drawings needed for tooling and preparations
– Tooling creation
– Assembly line setup
– Tester box building
– Produce first Mitte samples of 20 – 30 units
– Test samples, carry out inspections, attain certification and evaluate production
At this stage, if we can assure the performance, reliability and quality of these first samples, then we can move ahead with getting everything ready for production and shipping. However, if there are issues with these samples, we’ll have to go through iterations and modifications to fix them. We will keep you informed as we go along.
How did you decide on the shipping fee?
We calculated the cost based on current volume estimates, weight of the machine, method of shipping, and location from where we are shipping from (Hong Kong). In addition, the shipping fee includes custom duties and import tax so you won’t have to worry about that.
Why do you not ship to my country?
We are positively overwhelmed by the interest coming in from around the world. However, aside from a one-time shipping of the Mitte machine to users, we have to consider other issues such as setting up long term supply chain and delivery of mineral cartridges to thes, and the establishment of partnerships in the region so they can support and repair Mitte machines if any issues arise in the future. We are definitely looking into expanding the countries for which Mitte is available in, and we will keep you updated on our progress.
What is the warranty of Mitte?
We will have a standard warranty of 2 years as required by law, but everything is engineered with great care to last at least 5 years under highest usage. We will also provide after sales support in the countries that we ship to, so that if anything goes wrong, the issue can be solved within your home country.
Take control of your
We appreciate your interest in Mitte.
We’re a young startup driven to reinvent the way we drink water at home. We are in the production phase now, and will release Mitte in limited batches to ensure the quality and performance of each unit.
