WHOLE HOUSE FILTERS
FILTRATION
A "must" in every household - for optimum protection and maximum quality in mains water installations
On the long journey from the water treatment plant to your home, particles such as dirt, sand or rust can get into the water supply and thus into your domestic water installation. This can be as a result of new connections or maintenance work on the public supply system. If you get your water from your own well or spring, the problem of impurities can be even greater in some cases. A drinking water filter as part a total drinking water solution enables you to protect your home against water-borne foreign particles and help ensure a supply of fresh hygienically untainted water.
No more unwanted intruders
Installing a whole house drinking water filter makes sense because it forms a barrier against the undesirable elements that can spoil the taste and quality of your water around your home.

How does a drinking water filter work?
How it works
In whole house filters, the filter element works like a fine sieve: dirt particles and suspended matter larger than the openings in the sieve are held back on the filter surface and can no longer get into the water pipe. The water is cleaned mechanically. The performance of the filter is specified in μm (micrometres). BWT standard drinking water filters have a performance rating of 90 μm. By way of comparison: the average diameter of a human hair is approx. 100 μm while the BWT range of replaceable 10” cartridges can be specified with filtration levels from 25 to 1 micron.
But not all whole house filters are the same! A distinction is made between replaceable filters and backflush reusable filters.
Replaceable filter
In the case of replaceable filters, cleaning is carried out by replacing the filter element. To ensure a high degree of drinking water quality the filter element should be changed at least every six months.
In the E1 single-lever filter, BWT has developed a completely new type of filter. Thanks to its unique design and the single-lever operation, changing the filter unit is extremely convenient and easier than with most any other filter.
Backflush filter
In the case of backflush filters, cleaning is triggered by opening a flushing valve. Part of the filtered water is diverted and flows through the filter element in the opposite direction. So the particles of dirt are loosened and flushed out via the drain. Depending on the model, backwashing can be triggered automatically or manually and should be done every two months.
All BWT backflush filters - such as the BWT R1 - work with 2-phase back flushing: Coarse particles are washed out in the first phase, while the fine filtering of the filter element takes place in the second phase.
Frequently asked questions about drinking water filters
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.
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.
