Because of it’s filtering efficiency, you have to change the filter on a regular basis. By prolonging the change, you risk making the filter a breeding ground for the micro-organisms that are in it. It’s also more expensive than the other filters.
Air ionizers work by charging airborne particles or ions and emit these in the air to combine with impurities such as dust, bacteria, and other allergens. Once these particles clump together, they become too heavy to float in the air and thus settle on furniture or on the floor.

When choosing among air purifiers, you should also consider the installation requirements as well as the costs that come with maintenance and cleaning. Still, the benefits may outweigh the disadvantages especially where your family’s health is concerned.
