PurePower makes a line of off-grid power supplies that eliminate high levels of distortion on the utility power line. Today as never before, non-linear loads in our homes and businesses cause harmonic distortion on the electrical circuit.   Linear loads like lightbulbs and motors are not to blame, they are steady-state, meaning their demand for power is linear.   Non-Linear loads such as CFL lightbulbs and the switching power supplies that run our computers and keep our portable devices charged do cause harmonic distortion on the electricity throughout the house or building.  

Watch this video from Eaton, a leading provider of power quality solutions at the industrial level.  You will see how these non-linear loads damage the performance of any device, such as an HDTV or good audio system.
