Research by electronics company Sharp has shown that positive and negative ions produced by their air conditioning systems can inactivate viruses including influenza. But the new study is the first to link such an effect to reduced infections in hospitals.
The Short Answer. Most ionic air purifiers (ionizers) are completely safe and not bad for your health. They emit negative ions into the air as a way to clean it which is harmless to you. They're often confused with ozone generators which emit high levels of ozone that can be bad for health.
Some types of electronic air purifiers, like air ionizers, may release small amounts of ozone as a byproduct. In that case, they're generally safe and can't make you sick or cause issues, but they're simply not effective and are not worth the money in my experience.
Yes, ionizers do kill germs. According to research, both negative and positive ions have bactericidal effects (i.e. kills bacteria). The ions that ionizers produce create oxidative stress which reduces bacterial survival.
Air Ionization. The electric field causes the surrounding air to become separated into positive ions and electrons -- the air is ionized. Keep in mind that the ionization does not mean that there is more negative charge (electrons) or more positive charge (positive atomic nuclei / positive ions) than before.
Ionizers cause particulate pollutants to clump together because of the electrical charges the purifier gives them. Moreover, odors are caused by molecules of gaseous pollutants in the air, including volatile organic compounds (VOCs).
Some critics believe that air ionizers give off dangerous levels of ozone which is not only harmful to the environment, but can be equally as hazardous to your health. When inhaled in high enough doses, ozone can have harmful effects– including damage to your lungs, chest pain, coughing, or shortness of breath.
The major difference between an Ionic air purifier vs HEPA air purifier is how each product removes impurities from the air. An Ionizer operates by sending out electrically charged ions into the air that bond with harmful impurities. Once a bond is made, these particles become too heavy to stay in the air.
A built-in independent ionizer helps to trap airborne particles and more efficiently clean the air in your home. This may help you breathe better, as long as you are vacuuming and dusting frequently. However, an ionizer's usefulness can be hampered if you don't change the HEPA filter often enough.
An ionizer would remove spores from the air, however the spores are not usually the source of the mildew smell. According to the EPA, “Some compounds produced by molds have strong smells and are volatile and quickly released into the air. Ionizers will not remove these odors, although the ozone smell might mask them.
Should you use an ionizer? Given their general lack of effectiveness and the potential hazards of generating ozone in your house, we do not recommend using an ionizing air purifier if someone in your house has asthma or other respiratory problems. The EPA also cautions against generating ozone in your house.

The ionizer does nothing to kill or destroy the mold spores, it just makes them settle out of the air faster. Thus the answer to our question is: No, ionizers do not kill mold spores. They also will not have any effect on mold growing in your house.
Ionization Test Kit
Hold the meter approximately one foot (30.5 cm) in front of the ionizer. Monitor the display. The value displayed is the offset balance of the ionizer, which is the difference between the number of positive and negative ions being emitted.They do work, in that they do what they are designed to do, but that may or may not line up with your expectations for an air purifier. Other types of car air purifiers work by generating ozone, which is a whole different can of worms.
In the case of air ionizers, these negative ions aren't naturally occuring, but instead are created through a method called “electric-discharge”. During the process of electric discharge, the negative ions that are produced may give off ozone, which can be a very harmful and toxic gas.
HEPA filter air purifiers
They will remove the visible “smoke” elements of cigarette smoke and may slightly reduce the smell. However, they are not effective against VOCs, and the toxic gases in cigarette smoke are potentially the worst part of it.Ionizers will not remove these odors, although the ozone smell might mask them. Cooking smells – Much like smoke, cooking smells are made up mostly from VOCs released by the food when it is heated, along with some particles. An ionizer will remove the particles, but will mostly not affect the odor.
Leave your air purifier on all the time.
If you're concerned about energy usage, turn the fan speed to low. (Luckily, most air purifiers don't require very much energy only about the same amount as your computer.) You cannot run an air purifier for a couple of hours and expect your air to remain clean.The regulations require air ionizers to produce fewer than 50 ppb of ozone by air volume. However, these purifiers rarely include statistics to let consumers know how much ozone they generate. As ozone is a potential danger, air ionizers may not be safe for your pets or anyone else in your home.

Water ionizer. A water ionizer (also known as an alkaline ionizer) is a home appliance which claims to raise the pH of drinking water by using electrolysis to separate the incoming water stream into acidic and alkaline components. The alkaline stream of the treated water is called alkaline water.
Headaches, sore throat, coughing, Asthma attacks, and difficulty breathing are a few of the symptoms that can be brought on by some air purifiers. Yes, that's right. Your air purifier may actually aggravate many of the health issues you hoped it would solve.
Negative Ions (Anion) abundant in the nature, the God blessing gift, put our body in alkaline and in alkaline, bacteria, virus, cancer cells can't develop; can cure even incurable cancers, diseases. Negative Ions, “Nature's Battery Chargers”, are a major natural element that provides energy to the human body.

Instead of relying on fans to move air through filters, the machines release a steady stream of negatively charged ions that electrify the bits of dust, dander or other flotsam. The airborne particles pick up the negative charge and become strongly attracted to positively charged collection plates inside the machine.
Ionization or ionisation, is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.
An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle.
Ionization or ionisation, is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.
Although some research supports some positive effects of exposure to negative ions, there is no evidence-based medicine that supports negative ion therapy. So don't bother getting any home negative ionizers. They can produce dangerous indoor ozone and just waste space and electricity.
