Virtually all particles in the air have a positive charge, while negative ions have a negative charge. In which case, negative ions and particles magnetically attract to one another. When there is a high enough concentration of negative ions in the air, they will attract to floating particles in large numbers.
Ions start to cross the membrane in the direction of the electrochemical gradient, further pushing the potential toward positive that opens even more channels. This proceeds explosively until all of the available ion channels are open, resulting in a large upswing in the membrane potential.
