What is point-of-use?

Point-of-use (POU) filtration is literally filtration at the point where water is used.

This means that the water is being purified for bacteria at the water outlet – just at the moment when the clean water is needed.

Point-of entry (POE) filtration is the process of filtrating the water centrally, at the point where the water enters the building.

Even though clean water enters the building and a point-of-entry filter is in place, there might be a risk of contaminated water, which can be caused by build-up of biofilm in water pipes or a central water installation. The point-of-use filter is therefore the ultimate solution to ensure clean water to the users.

Why point of use?

We recommend the useage of point-of-use filters as a permanent solution in hospitals and care homes against pathogenic waterborne bacteria that could be life-threatening to immunosuppressed patients and residents.

In case of increased bacteria contamination the fastest way to solve the problem is to install a point-of-use filter, which will provide an immediate and safe protection of the users. Additionally this solution will also avoid closing down the facility, which may be both costly and annoying for the users. At some locations a point-of-use filter product is used as an intermediate solution until the root-cause has been identified and solved.

When to use

  • As an interim safeguard where control measures have been ineffective e.g. laboratory analysis results confirming the presence of harmful micro-organisms in the water system, loss of temperature control, loss of disinfection application or control.
  • As a long-term safeguard where there is no effective alternative or where additional protection is required for vulnerable patients, residents or building users e.g. in augmented care areas or residential care homes.
  • During engineering remedial works
  • Where high levels of disinfection of water systems may dislodge biofilms
  • Seasonally unoccupied buildings, that are not drained down or decommissioned
  • Where there is a confirmed or suspected infection from the water system
