Yes. Proper wiring.
The problem here isn't your humidifier. The problem is the circuit it's on, or the building's service, can't handle the load.
Those aren't spikes, they're brownouts. A surge suppressor will do nothing.
This is probably a common consumer appliance and they are sized specifically to work well on ordinary consumer circuits (though they will dominate). So the problem is either
- a super defective circuit
- too much other stuff on that circuit
- this is revealing a serious problem with the building wiring.
So go shut the breaker off that powers this humidifier. Go see what else also turns off. (Save your files). It helps to have a night-light to stick in outlets. You may find your answer.
At this point it may be time to survey your entire house's receptacles as to which receptacles are on which circuit. Happens all the time where people stack every single load on the same circuit while three others go unused, they just don't know any better.
For bonus points, get a $20 Kill-a-Watt meter and test each of your appliances and see how much power they also draw. Make a chart of how many watts (better: VA) you are putting on each circuit.
If getting your circuits sane does not work, then you have a power problem. It is also possible this is a neutral problem, either within a multi-wire branch circuit or for the entire house. The giveaway here will be that your voltage is not 120 (or 230/240 in Europe) - and your Kill-a-Watt will tell you that. We use 120V in America.
At that point expect to see ratty old scary panels and wiring. These things will burn your house down, so it's maybe time to think about a rewire -or if your panel will take them, AFCI breakers.
