The Negative Effects of Ionizers

Ionizers employ negatively or positively charged ions to take dust and odor out of the air. The charged ions attach themselves to particles in the air, which then causes them to return to the ionizer or stick to other surfaces. The capabilities of ionizers are often overstated; and, in fact, the devices can cause negative effects when in use.

  1. Turns Walls Black

    • When a dust particle becomes charged from an ion, it seeks to attach itself to something. Often, the particle is collected on a charged plate inside the ionizer, and therefore is removed from the air. Sometimes, however, the dust particle will stick to other objects, such as a wall or table. This is especially true of charged particles that are further away from the ionizer. As a result, excessive dust can build up on walls over a period of several months, turning them black and grimy.

    Can Exacerbate Asthma

    • Ionizers are often marketed as reducing the symptoms of asthma, but research suggests that the devices can make it worse in some cases. Some small-charged particles end up not being collected or attached to a surface, allowing them to remand suspended in the air. Breathing in these charged particles can exacerbate asthma symptoms. Ionizers also produce ozone as a byproduct of use, which tends to worsen respiratory problems, including asthma.

    Can Cause Sore Throats and Headaches

    • The production of ozone is one of the most alarming aspects of ionizers. Although it is relatively harmless in small doses, overuse of ionizers can produce enough ozone to cause sore throats and headaches. At higher levels, the gas is toxic. Some consumers fear that improper use of an ionizer or a malfunctioning device can lead to ozone levels that are not safe. Excessive ozone can also damage the lungs and cause severe respiratory problems.

    Does Not Kill Bacteria or Mold

    • One the biggest misconceptions of ionizers is they make the air safer by killing bacteria and mold. In truth, an ionizer can only remove them from the air, at best. Some particles, such as pollen, tend to be too big to be affected. Use of an ionizer may make people complacent to overlook the necessary precautions used to prevent the spread of infection, such as properly sanitizing the household or cleaning it effectively.
