Ionizers are devices that use negative ions to remove certain particles suspended in the air. The purpose of an air ionizer is to help these particles settle and accumulate in the air, thus improving indoor air quality. The basic principle behind an HVAC ionizer is to release charged ions into the air stream. These ions must give up or absorb an electron to become neutral.
As a result, they are attracted to particles that float in the air and stick to them. Sick Building Syndrome (SBS) is a condition that affects people while they are in an affected building. Symptoms of SBS include headaches, dizziness, and fatigue. Fortunately, these symptoms disappear as soon as the person leaves the building.
This condition is common in commercial buildings, classrooms, and offices. When workers suffer from SBS, their morale and productivity suffer. They take more days off work, resulting in losses for businesses. An ionizer for an oven does not filter Volatile Organic Compounds (VOCs).
Instead, it interacts with them, breaking down the compounds and effectively neutralizing them. This method does not require the replacement of carbon filters like those required in a traditional air purifier. There are two types of air ionizers: electrostatic precipitators and ion generators. Both types give an electrical charge to polluting particles.
Charged particles, or ions, are attracted to oppositely charged particles (because science). The charged particles will then stick together. The difference between electrostatic precipitators and ion generators is how they charge the particles and what happens to the particles after they are changed. Electrostatic precipitators use high voltage to charge particles and then collect them on a plate or filter.
Ion generators use a low voltage to charge particles and then release them back into the air. An official website of the United States Government Use of official websites.

Ion generators work by charging particles in a room so that they are attracted to walls, floors, tables, curtains, occupants, etc.
Abrasion can cause these particles to be resuspended in the air. In some cases, these devices contain a collector to attract charged particles back to the unit. While ion generators can remove small particles (e.g., dust), they cannot remove larger particles such as pollen or pet dander. They also cannot remove VOCs or other gases from the air.
Although some have suggested that these devices provide a benefit in rectifying a hypothetical ion imbalance, no controlled study has confirmed this effect. Ozone, a lung irritant, is produced indirectly by ion generators and some other electronic air purifiers and directly by ozone generators. While the indirect production of ozone is a cause for concern, there is even greater concern with the direct and intentional introduction of a lung irritant into indoor air. There is no difference, despite the claims of some vendors, between the ozone present in outdoor smog and the ozone produced by these devices.
Under certain conditions of use, ion generators and other ozone-generating air filters can produce levels of this lung irritant well above levels considered harmful to human health. A small percentage of air purifiers that claim to have health benefits may be regulated by the Food and Drug Administration (FDA) as medical devices. The FDA has set a limit of 0.05 parts per million of ozone for medical devices. While ozone can be used to reduce odors and pollutants in unoccupied spaces (such as eliminating smoke odors from homes affected by fires), the levels needed to achieve this are above what is generally considered safe for humans.
Ionizers emit negative ions which remove some particles and pollutants from the air. Using a plasma ionizer can alleviate some problems and improve air quality. It's important to know what this device can and can't do, plus some of the potential negative aspects of installing one in your home. There are some benefits and some drawbacks to consider when installing an HVAC ionizer in your HVAC system.
It generates ions that are injected into the stream. Installing a common ionizer air purifier for an oven takes 2 to 4 hours depending on its location, ease of access, your level of experience, and other factors - such as The Home Needlepoint ionizer (Pure-Plasma Air 600), which is easy to install and cleans areas of up to 2400 square feet - more than enough for most homes in Canada and North America. Research has shown that furnace ionizers installed as part of an air conditioning system and air purifiers located in shared building spaces help eliminate viruses and pollutants from the air including mold, bacteria, and allergens. If you have an ionizer or plasma ionizer with ozone production it is very important to control the ozone level. Ozone levels should be monitored regularly with an ozone monitor or detector.
