What is the Difference Between an Air Purifier and an Ionizer?

Both the air purifiers and the ionizers clean the indoor air, but they act in a different way.

The air purifier operates using a fan and filters. The fan sucks air in the room and blows it through the filters. The air that passes through the filters becomes clean from particles, allergens, bacteria … etc.

The ionizer produces negative ions using electricity. The negative ions are attracted by the positive particles in the air – such as dust, tobacco smoke and smog that – really small with a size between 0.01 and 0.1 µm/microns. When the negative ions stick to the positive particles in the air, they become heavier and may fall on the ground. In this way the air gets cleaned from the unwanted pieces.

There other benefits of the negative ions. They may stop the growth of viruses. And also when they interact with the positive particles, ozone is generated that can kill bacteria, fungi, and mold.

But talking about the differences between the air purifiers using filters and the ionizers using negative ions, there are some more details to be considered.

The air purifies are efficient for a wider range of particles such as large allergens like dust and pollen as well as smaller ones such as pet dander, bacteria, and viruses. This means that they are suitable for the people with pet allergies, hay fever, and asthma.

The ionizers are efficient for a smaller range of particles, especially the ones with a smaller size – such as dust, tobacco smoke and smog with a size between 0.01 and 0.1 µm/microns. So, this means that the air ionizers may not be so good at eliminating the triggers of allergies and asthma and if you suffer from these – choose an air purifier.

But in addition – the air ionizers may stop the growth of viruses and may kill bacteria, fungi, and mold.
