BARs (Barometric pressure) is the force your espresso machine exerts on the grounds of coffee while pumping high-pressure water. 9 BARs means that the espresso machine is forcing heated water through the ground coffee at 9 times the Earth's current atmospheric pressure.
The pressure of your machine is crucial because it allows water to pass through the coffee grounds at the correct speed and intensity. If the pressure is too low, the dissolved oils and flavors aren't extracted properly. If the pressure is too low the dissolved flavors and oils won't be extracted properly.
The pressure of your espresso machine can be controlled by adjusting the screw on the espresso pump. Commercial machines and top-end home machines come with pumps that rotate with adjustable pressure. For home machines that are less expensive that utilize a vibration motor, it's impossible to alter the pressure with DIY hacks. However, companies such as Cafflano are working on technology that uses Pascal's Principle to maintain pressure within the portafilter during the beer making process.
Temperature
Temperature is one of the most important aspects in a perfect espresso shot. Too hot water can burn the coffee grounds, resulting in bitter drink. The ideal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all of the desired coffee flavors without burning the grounds or over-extracting.
The top espresso machines include a thermoblock which will heat the water, and keeps it at a stable temperature throughout the whole extraction cycle.

It is recommended to use a filter which does not use chlorine and adds a small amount (TDS) of total dissolved substances to provide calcium and magnesium. This will result in an optimal balance between alkalinity and hardness and reduce the necessity of decalcifying your machine.
Using a high quality filtered water is crucial for your machine's long-term health as well as the flavor of the coffee it produces. Based on the usage and hardness of your machine you should use descaling products regularly. They are available in tab, liquid, or powder form at most hardware stores.
