ABSTRACT:
An air purifier has a simply manufactured and assembled ionizer, which increases the charging efficiency for dust particles through maximally increased discharge spaces and prevents electrical accidents. The air purifier includes an ionizer and a collector. The ionizer includes two ground electrode units and at least one discharge electrode, the two ground electrode units each having one or more electrodes, each formed in a hollow semi-cylindrical shape, the two ground electrode units being joined to face each other, the at least one discharge electrode being placed in spaces formed between the hollow semi-cylindrically shaped electrodes of the joined ground electrode units, thus charging dust particles passing through the spaces between the hollow semi-cylindrically shaped electrodes. The collector is electrically charged with a polarity opposite to a polarity of the charged dust particles.
