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.
For a list of the harmful effects positive ions can have on your health see the page on What are Negative and Positive Ions?. How Do Negative Ionizers Work? You do have one negative ion generator in your home already. Your shower, with its stream of hot water and steam, is a good producer of negative ions. Thatâs likely part of why so many people need a shower to wake up in the morning. Itâs not much use in the other rooms of your house though.
