Filtering water with Filbec

Tested quality

Bacteria in drinking water pose a major health risk 

Bacteria can enter drinking water in a variety of ways and pose significant health risks. From diarrhea caused by E. coli to severe pneumonia, many things can happen. Antibiotic-resistant bacteria pose an additional danger, especially for people with weaker immune systems. It is therefore essential to declare war on bacteria in drinking water. Peacefully, with a very good water filter. With filbec.  

Although drinking water in Germany is generally very well monitored microbiologically, bacteria can enter tap water in several ways. First, they originate from raw water, i.e., groundwater or surface water, from which waterworks extract drinking water. Natural bacteria, such as coliform germs, can be present in the water, especially after rainfall or flooding, but are largely removed through treatment and disinfection (e.g., chlorine, ozone, UV). 

Pipes and domestic plumbing can also contribute to contamination. Bacteria can settle on the inner surfaces of pipes as biofilm, especially in plastic pipes or when water stands for long periods of time. Deposits in tanks or fittings and rarely used pipes, such as in vacation homes or garden sheds, also promote the growth of germs. Examples of bacteria that can be found in tap water includeLegionella, which mainly multiplies in hot water systems above 25°C,coliform bacteria or E. coli, which indicate fecal contamination, andPseudomonas aeruginosa, which is particularly relevant in medical facilities. 

Our filters remove all bacteria from your tap water.

Bacteria in drinking water

How do bacteria get into our tap water? 

Bacteria can enter tap water from various sources. In principle, tap water in Germany is very well monitored microbiologically, so the risk to the general population is low. Nevertheless, there are ways in which bacteria can enter the water:

Raw water / water source

  • Groundwater and surface water: Waterworks extract water from rivers, lakes, or wells. 
  • Natural bacteria (e.g., coliform bacteria) are present in water, especially after rainfall or flooding.
  • Waterworks use disinfection (chlorine, ozone, UV) to eliminate these germs. 

water treatment 

  • As a rule, filters, UV systems, and disinfection remove most bacteria. 
  • Technical malfunctions or failures in the treatment process can result in some germs getting through. 

Pipes and domestic plumbing

  • Biofilm formation: Bacteria can colonize the inner surfaces of pipes, especially in plastic pipes or when water stands for long periods of time. 
  • Pipes, tanks, or fittings: deposits or water storage tanks that are not cleaned regularly can harbor germs. 
  • Stagnant water: Bacteria can multiply more easily in pipes that are rarely used (e.g., vacation homes, garden sheds). 

Examples of bacteria in tap water 

  • Legionella bacteria: These can multiply in biofilms, particularly in hot water systems (above 25°C). 
  • Coliform bacteria / E. coli: Indication of fecal contamination, very rare in Germany. 
  • Pseudomonas aeruginosa: Relevant in medical or sensitive facilities, rarely found in normal tap water.

In a study in which tap water was collected via filter membranes, a microbial community and cultivable bacteria—including antibiotic-resistant bacteria—were found in "normal" tap water. Although the water met legal requirements, bacterial DNA was detectable.

How can bacteria be removed from drinking water?

In the private sector, only high-performance filters such as ours are currently capable of removing 99.99% of such substances from the water.

Activated carbon block filter
(adsorption of organic compounds)
Ion exchange filter
(Binding of charged PFAS molecules)
Membrane filtration
(physical separation at the molecular level)
