Installing a drinking water filter makes sense because it forms a barrier against dirt and particles entering your domestic water system. What many people don't know is a whole house filter is ideal for protecting drinking water supplies and appliances.
Product details
BWT E1 FilterThis filter is designed to provide high quality whole house filtration simply and safely by preventing particles such as rust and sand from entering your home's domestic water supply system. While there are many other filters on the market they all tend to have one thing in common - the filter elements aren't back flushed or replaced regularly because doing so is either time consuming or in many cases simply too complex. The BWT E1 filter is not only easy to install and effective in use, it’s ingenious design makes the age old problem of changing the filter child’s play.
The single lever operation shuts off the water supply, relieves any pressure and then releases the hygiene vault (the filter cup containing the filter element) in one simple action, allowing the filter element to be removed and recycled along with your domestic waste. A new filter can then be removed from its hygienically sealed wrapper and slipped back inside the hygiene cup. The single lever can then be pulled down, locking the new filer in place and switching the water back on. This revolutionary approach helps ensure that the filer is changed regularly, maintaining the integrity of the filter system.
- Release the locking device, which also shuts off the water
- Raise the lever and eject the hygiene vault automatically
- Insert the new hygiene vault. Lower the lever. Lock. Ready!
And all in less than 30 seconds.
BWT has effectively mitigated the hygiene risks associated with conventional filters, as you no longer have to touch any parts that come into contact with the water! What's more, the E1 prevents splashing when replacing the hygiene vault and the water pipe does not run dry.
The BWT E1 filter is available as the E1 HWS (domestic water station) including pressure reducer or as the E1 EHF (single-lever filter) for applications without pressure reducer.
Get your 10-year warranty!
With the E1 filter you no longer have to worry about forgetting to change the filter unit: An email notification tells you when the hygiene vault needs to be replaced. By registering your E1 single-lever filter you automatically receive a 10-year manufacturer's warranty.
Highlights:
- Easy replacement of the filter unit – no tools, no mess and no splashing
- Automatic shut-off of the water supply in a single action
- No touching of parts that come into contact with water
- Manufactured in compliance with HACCP food safety standards
- Filter element replacement reminder: via an email reminder service
- DVGW-certified

Frequently asked questions about BWT drinking water filters
What effects does too hard water have?
"Hard water leads to limescale depoits which can mean increased energy costs due to the reduced performance of boilers and hot water tanks.
The frequent need to descale of coffee machines, kettles and instantaneous water heaters.
Up to 50 % higher detergent consumption
Significantly more work to maintain the bathroom and kitchen.
The service life of water-bearing equipment can be significantly shortened, and premature failure more likely
"
Where can I get further advice and who assesses the need to add minerals to my drinking water?
In the first instance obtain a full water annalysis from an independent surveyor and the contact your BWT Customer service team who will guide you through your options.
Why does hard water make household work more difficult?
Hard water especially when heated leaves small deposits of scale around your home. These take many forms, spots on glasses and cutterly, unslightly stains on tap and shower screens and as scum when combined with soap. These build up over time and are difficult to remove without specialist cleaners.
How does hard water affect the skin?
Hard water together with soap forms insoluble salts, called scum. This scum deposits on skin and hair. Many people then feel a feeling of tension on the skin and complain about dull, lifeless hair. With soft water the skin feels softer and silkier, the hair is shinier and smoother.
Why can hard water pollute the environment?
With very hard water, up to 50% more detergent is needed to achieve the same cleaning effect as with soft water. In addition, aggressive cleaning agents are often used to remove limescale stains from tiles, taps and sanitaryware - both pollute the waste water. Not to forget: Even a limescale layer of 1 mm on heat exchanger surfaces increases energy consumption.
Which devices is the hygienic safe suitable for?
- BWT E1 single lever filter HWS
- BWT E1 Single lever filter EHF
- Cillit C1 single lever filter
How often does the hygiene safe have to be changed?
According to the standard, the filter element must be replaced every 6 months.
What does "inner pipe sealing" by mineral dosing mean?
BWT dosing units add a small amount (approx. 3 mg/l) of minerals to the drinking water in line with current water consumption. (Limit value of the drinking water ordinance: up to 5 mg/l). The minerals form a protective layer in the pipe which separates the pipe material from the water (inner pipe sealing). Existing sources of corrosion can be infiltrated and thus stopped. The inner pipe sealing can thus become a life insurance for your pipe installation, which is destroyed without appropriate protection and causes high consequential costs (pipe bursts, pipe replacement).
Does the sealing of the inner pipe also make sense with older, possibly already corroding systems?
Even already corroded pipe systems can be gently rehabilitated by mineral dosing. The protective layer prevents further contact of the aggressive water with the pipe wall.
Is it permissible to seal the inner pipe with phosphate minerals according to the "Food Codex"?
The mineral solutions from BWT (Quantophos) have food quality and the addition is permitted with tested dosing systems up to the limit value of 5 mg/l according to the Drinking Water Ordinance. Bewados dosing systems from BWT operate exactly in accordance with the requirements of the Drinking Water Ordinance and are precisely set at the factory.
How can corrosion processes in a domestic water system be identified?
In the case of galvanised pipe systems, the reddish-brown discolouration of the water is a problem.
On rust or sand-like particles in the tap sieves.
For copper pipes, the blue-green discoloration of the water and objects.
For new installations, the probability of later corrosion can be determined by an expert through analysis of your water.
Do the dosed minerals in drinking water have a detrimental effect on the taste of food when used in the preparation or cooking ?
No, minerals have no effect on the smell and taste of drinking water. This also means that the cooking and preparation of food is not affected. Minerals are basic elements for the structure and metabolism of the human body and are contained in thousands of higher concentrations in other foods.
What are the concentrations of minerals in water and other foods?
The food-safe BWT dosage active ingredients are based on valuable phosphate minerals. Phosphates are contained in many foods and in the human body. They are a bone component, necessary for the metabolism and indispensable for brain and muscle activity. The limit value for phosphate is 5 mg/l according to the Drinking Water Ordinance.
What does ÖVGW/DVGW-tested mean?
The DVGW is the German Association of Gas and Water Experts, which lays down, among other things, the guidelines for the construction, testing and use of plants for the treatment of drinking water. The ÖVGW is the Austrian counterpart. While WRAS does a similar job in the UK. Devices bearing these test marks comply to local standards and may be installed in drinking water installations without further measures. Only tested devices are subject to strict testing with regard to the materials used, and hygiene.
A GS mark, CE mark or similar alone are no proof of compliance with the applicable requirements with regard to hygiene and process success in drinking water.
What is rust / corrosion?
The chemical reactions that occur when metallic materials come into contact with water are called corrosion. Corrosion is therefore a natural process, the best known form of corrosion is the formation of rust in iron and steel. A form of copper corrosion, for example, is known as "verdigris".
What damage is caused by corrosion?
Corrosion can cause premature failure in pipework, valves to stick and reduced efficincy in radiators. In extreme cases corrosion can cause blockages and reduced flow rates distrupting boiler performance and increasing costs.
Microbiological impairment of drinking water (corrosion products are a habitat and food for dangerous bacteria, e.g. Legionella)
.
Stubborn discolorations on sanitary ware (partly not removable)
and discoloured garments when washing laundry.
What measures should be taken to protect against corrosion?
The affects of corrosion can be mitigated against through good system design and good installation practices such as rinsing through new lines before they are sealed. The use of a particle filter like the BWT E1 and corrosion inhibitors like the AQA Nano and BWT Combi Care. And the strict adherence to all local regulations.
How are the minerals added to drinking water?
Electronically controlled dosing systems with DVGW approval mark record exactly the current water consumption via a built-in water meter. The electronics directly controls the pump via the consumption data, which doses exactly the required quantity of minerals. Bewados dosing systems from BWT guarantee the correct addition of minerals and are therefore extremely economical.
How often do I have to service my drinking water filter?
According to the standard, the filter element of the E1 single-lever filter or a spin-on filter must be replaced every 6 months. For backwash filters, the filter should be cleaned every 2 months.

What is limescale ?
Read in the section "Worth knowing" in our magazine article what limescale is and how it gets into drinking water.
Are water suppliers obliged to provide clean water?
Your water supplier is the guarantor that you get drinking water delivered to your home. The strict principles for this quality are laid down in the Drinking Water regulations. However, in your domestic water network this quality can be lost through heating, different materials etc. - problems such as limescale and corrosion can develop. The responsibility for the drinking water changes when it enters your home from the supplier to the house owner. Thus the "operator of a drinking water system" is responsible and influence the quality of the water at the tap.
