A common question we continue to hear is about the PSI on a steamer for bed bugs. The PSI is measured not at the tip, but at the actual tank (where the water is held). Having a high PSI is a good thing as the higher the PSI or the tank pressure, the higher the steam temperature will be.
The next part of a steamer is at the tip where the steam comes out. Many people think that having a high PSI can be bad as it will just blow the bed bugs around, but this is just not true. Most higher end steamers have a steam control knob, which allows the user to adjust how much steam comes out. Even though the PSI in the tank is still high, the amount of steam can be limited. Limiting the amount of steam that comes out offers better control and stops the steamer from blowing the bugs around.
A final point to make is by lowering the steam that comes out, the tip temperature will not be impacted. The tip temperature may actually be higher if the pressure knob is turned down as the PSI will remain higher with less steam being emitted.
I hope this will help others as its a VERY common question that we hear.
