Ionizers use high voltage to give an electrical charge (usually negative) to either particles that move through the ionizer, or to molecules in the air. These charged molecules are called ions, and the ions will then stick to particles. In either case, the end result is particles with an electrical charge.

Charged particles are attracted to particles or surfaces with the opposite charge. This causes the particles to clump together, forming larger, heavier particles that settle out of the air onto nearby surfaces. Alternately, particles can be attracted to, and stuck to, charged surfaces like carpet or curtains that have gained a positive charge through static electricity. Electrostatic air purifiers take advantage of this fact by providing a positively charged collector plate that attracts particles. Regular ionizers do not have a plate, so the particles end up on the floor or stuck to the curtains somewhere else in the room.

There are two types of pollutants you need to deal with to improve your indoor air quality: particulate pollutants and gaseous pollutants. To determine if ionizers are effective, we need to address both types.

The process of using an electrical charge to generate ions also creates ozone gas. Ozone can be used to decontaminate and sterilize indoor areas, and is often used for that purpose. However, at effective concentrations, it is very dangerous. Ozone is toxic and is a lung irritant even at low concentrations. It can also react with gaseous pollutants, but there is no way to predict what other chemicals this reaction will create (ozone reacts with some common household pollutants to create formaldehyde, for instance). Generating ozone in your house is a major drawback for ionizers.

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.

If you want to remove particles such as dust, pet dander, pollen or mold spores from the air in your home, HEPA filters are a decent option, known for their efficiency and track record. If you have problems with gaseous pollutants, including fumes from paint or out-gassing from carpets or furniture, or simply want to get rid of bad smells, a carbon filter will do a good job for the most part. However, carbon filters also need regular changing, and are not effective against particulate pollutants. There are units on the market that contain both HEPA and carbon filters. Molekule even offers ozone-free air purifiers.

Our solution for indoor air pollution, the Molekule air purifier, contains PECO technology, that goes beyond trapping particles on filters to destroying particulate and gaseous pollutants, so it could be an excellent option for removing pollutants in your home.

Most of the major air purifier companies use ionizers in their air purifiers, including Xiaomi, Blueair, Levoit, and many more. The reason is simple: a cheap ionizer can slightly improve the efficiency of the HEPA filter. This way, air purifier companies with little added costs can market a higher CADR (metric measuring the effectiveness of air purifier), making it a cheap way to get a boost in CADR. Unfortunately, much of the time the user is unaware an ionizer is being used and unaware of the possible harmful effects.

Ionizers can create a variety of VOCs, including those produced by the Global Plasma Solutions bipolar ionizer in schools: acetone, ethanol, toluene, butyraldehyde, and acetaldehyde. Furthermore, an academic research study found that ionizers can actually create formaldehyde.
