Ionizers can also be combined with other air purification technologies, such as a HEPA filter for removing more particles from the air, or a carbon filter for removing volatile organic compounds VOCs , odors and other gaseous pollutants. Sometimes the filter is charged, so it acts as the collector plate in an electrostatic purifier. In the early s the Ionic Breeze ionizing air purifier was sold by Sharper Image in shopping malls across the U.
It was a new way of using technology to purify air, and for a while many people bought into the hype. But Consumer Reports tested the Ionic Breeze and found it ineffective at purifying air and later, potentially dangerous because it generated ozone. 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. Ionizers are not especially efficient anyway.
Fanless models clean a relatively small amount of air, and even models with fans have low clean air delivery ratings CADR. On the plus side, small, fanless models are very quiet and easy to move from room to room. Ionizers that use an electrostatic collector plate are more efficient—in fact, they are quite good at removing particles from the air.
However, this efficiency only lasts as long as the collector plate is clean. As it becomes saturated with particles, efficiency drops drastically. Electrostatic precipitators also draw a lot of electricity. 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. Should you decide you want to get an ionizer, the next step is finding the one that will work for you.

Here, we take a closer look at the difference between air purifiers and ionizers. If you're considering investing in either, we do have a guide to the best air purifiers right now.
Broadly speaking, air purifiers and ionizers perform the same function — they cleanse the air, removing allergens and pollutants. They can both remove particles measuring a thousand times smaller than a millimeter, but how they do it is very different. Air purifiers consist of one or more filters and a fan. How do they work? An internal fan pulls room air over the filter. Particles are then captured within the filter's many layers and pleats. Once that process finishes, clean air is recirculated in the room.
In contrast, air ionizers exploit the chemical properties of ions to remove particles and microbes from the air. Ionizers create negative ions using electricity and discharge them into the air.
If you are getting air purifier with an ionizer, you should check well for the range of probable ozone emission of the ionizer. As a matter of fact, air purifiers in this century has been constructed to taste, with the answer to your questions in mind of the producers.
They offer a wide range of purification options with some having air purifier with ozone generator that can be controlled and some others have no ozone generator.
You should be very careful of air ozonizers that are labelled as air purifiers. Amazon and the Amazon logo are trademarks of Amazon.

Air purifiers work based on the positive and negative charges, which are attracted to one another in such a way that: The moment you turn on your air purifier; voltage would be transmitted to some needle-like structure which then generates electrons that are sent into the air.
When these electrons attach with air molecules, negative ions are produced which may either be electrostatic or ionic. The ions which are produced then attach to positively charged impurities which are then trapped into the filter of the air purifier.
