BWT E1 filter – as hygienic, conve­nient and safe as never before

There are many water filters on the market, and all models are of state-​of-the-art design to prevent parti­cles such as rust and sand from ingressing your home's domestic water supply system. The perti­nent stan­dards even make installing such a filter manda­tory for every home's domestic water supply system. But instal­la­tion of the filter alone is only half the battle, as all filters have one thing in common: the filter elements aren't back­flushed or replaced regu­larly because doing so is in many cases too complex a task. And this poses a major problem for hygiene in drinking water supply lines.

BWT has devel­oped an inge­nious solu­tion with its BWT E1 single-​lever filter – a protec­tive filter offering inno­v­a­tive advan­tages in terms of conve­nience and hygiene. Replacing the hygiene vault (the filter cup containing the filter element) is so easy that consumers can do it them­selves in a matter of seconds:

E1 Einhebelfilter EHF wechseln
E1 Einhebelfilter EHF wechseln
  1. Release the locking device, which also shuts off the water
  2. Raise the lever and eject the hygiene vault auto­mat­i­cally
  3. 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 the BWT E1 single-​​​lever filter

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.

Can corro­sion in water pipes cause damage to health?

Corro­sion processes can cause heavy metals of the pipe mate­rial to enter the drinking water and impair the water quality. These metals can lead to health impair­ments, espe­cially for infants, the sick and the elderly. It is always there­fore recom­mended to allow the water to run freely to drain for several minutes after periods of non-​use.

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.

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.

Can the soft­ening process be relied upon?

Yes, the ion exchange process has proven itself for decades in many millions of devices world­wide.

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.
