Older low flow shower heads simply restrict the flow of water coming out of your shower, this has lead some people to believe that all low flow shower heads are the same and produce an inferior shower experience. It is important to note that the Methven Kiri Satinjet uses completely different technology to a normal shower.
What technology you might ask?
As the name suggests the technology is called Satinjet. Satinjet technology is based on the Venturi effect, where air is sucked in to the shower head through special breather holes to create large droplets of an air/water mixture with maximum surface area for minimum volume. The Satinjet head produces 150,000 of these droplets per minute.
So instead of most of the warm water simply flowing off your skin without imparting any warmth, as it does in a normal shower, the Satinjet covers your skin in a warm cloud of smaller droplets imparting maximum warmth to you even though the flow of water is much less than a regular shower. In short the Methven Kiri Satinjet is much better and more efficient than a regular shower head, which has to drench you in water to get the same warming effect.
