Medwyn Davies says:. "This showerhead has been a revelation. The shower experience is as good if not better than when I was using a showerhead with twice the flow."   

Stephen Kay, Managing Director, Cambridge Water PLC says :"I have tried a number of water efficient shower heads but this is the first to be completely acceptable to all my family!!!" 

Danny Davis, Senior Technical Officer, Chartered Institute of Plumbing and Heating Engineers says: "I have been very impressed with the Nordic Eco Shower, it not only saves water, but the technology behind it means that the reduction in water consumption is not to the detriment of the showering experience"

"We reviewed the Nordic Eco Shower for the magazine and loved it so much we decided to keep it! It's great to know that our lovely relaxing showers now use significantly less water, there is no limescale build up and they are very reasonably priced "

No Sieve Plate
For a bacterial culture to establish, it needs to anchor to a suitable surface. This can either be the biolm left as water cools across the face of the showerhead, the rubber nipples on traditional anti limescale heads or nooks and recesses in the layers at the face of some heads. The key to the Nordic Shower regarding this issue is that the only point where a biolm can potentially grow is at the face of the showerhead on a smooth metal surface, which is a fraction of the surface area when compared to the expanse of most showerheads. Metal surfaces do not encourage biolm growth.

Nutrition
Limescale contains many nutrients such as calcium, manganese and iron which will settle on certain areas of a showerhead when the water cools, most likely at the face. These layers of deposited materials are termed as biolm. Biolm and limescale tend to remain behind when the water evaporates.

Pooling of water in the recesses of a sieve plate type head and the nal drops from rubber nipples type heads tend to exaggerate biolm build up. As this pooling and cooling/evaporation occurs repeatedly, the layers of biolm deepen, embedding bacteria within, an ideal nutritional for growth and spore formation. Showerheads are ideal locations in a water system for this deposition of biolm to occur as most are aerobic and will have access to air here. These biolm deposits are reduced dramatically with the Nordic Shower.

Moisture
All organisms require water for survival and growth. Pooling of water in the shower head encourages such growth. Water will pool in the recesses of a sieve plate type head and sit until it evaporates or the shower is reused. This warm tepid pool provides an ideally environment and temperature for microbial growth.

Aeration
Aside from the majority of problematic bacterium being aerobic, the most common problem bacteria associated with water systems, Legionella, needs to be inhaled into the individual's lungs to cause an eect , so atomization caused by aeration or inner turbulence at the shower head provides the ideal conditions for transfer by inhalation. Unlike aerated-type ow controls, laminar ow does not draw ambient room air into the water stream, reducing dramatically the volume of airborne bacteria.

In summary, Nordic Eco Shower has a unique design and mode of delivery that reduces the suitability of an environment for pathogen. By using a metal contact area at the exit point makes for reduced risk of biolm build up. Without multi layers or sieve plates a non aerosoled and large droplet ow is obtained providing a healthier shower.
