The common computer 'surge suppressors' stop 'surges' or momentary overvoltages. You also have an issue with conducted emissions or conducted susceptibility. Either the generator is generating power that it should not be generating (specifically, not at the right frequency), or the powered equipment has a crummy power supply that permits whatever is on the power line to pass right into the internal circuitry. Or both. Whatever you get for filtering will have an insertion loss vs. frequency characteristic. Products for overvoltage surges are rated for their energy dissipation. Various marketing people will dress it up and obfuscate it, especially for retail products. You have a couple of concepts confused.
