What Does Ion Mean On A Fan? Get the Facts Right

Fans are typically pretty easy to understand. You turn the fan on, and it blows air to cool you down, right? The only thing you need to worry about is what speed setting you turn the fan on.

However, sometimes you might run into a fan with something on it that you aren’t familiar with.

What Does Ion Mean on a Fan?What Does Ion Mean On A Fan

When you see an ion on your fan, it stands for an ionizer. An ionizing fan is supposed to help easily clean the air in your room when it is turned on. air ionizers create negative ions into the air to purify from pet dander, pollen, dust mites, mold, dust particles, or airborne pollutants.

When you turn on the ionizer built-in to your ionizing fan, it will work to clean and freshen the air in the room. You will have fewer dust particles like pet dander circulating in the air, leaving you with fresher feeling air.

How Does an Air Ionizer Work?

air ionizers emit negative ions into the air that attract all of the positive ions. When the negative and positive ions combine and become one, they work to trap any pollution that might be roaming in your air. The ions then become one big cluster of positive ions, negative ions, and whatever pollutants they grab along the way.

Negative ions that are released into the air can create freshness in the clean air. It is also said that if there are enough negative ions in the air, it can even let off the feeling of well-being. However, negative ions generators might leave the area dusty,

The ionizer can also capture particles, so if you are not cleaning it enough, it will not work as efficiently as you would like it to. 

Ion Fan Setting

If your ionizing fan has an ion setting on it, you can choose whether or not you want to use it. There are benefits to using the setting that you might enjoy, but you are not required to use the setting if you don’t want to. 

The ion setting will help theair purifier to purify your air, relieve tension, and even improve your sleep. If you don’t want to use the setting all the time, try using it just at night to see if it helps you sleep better. 

Do Ionizers Really Clean the Air?

There is some debate on whether or not ionizers clean the air in the room or not. Do they clean the air? There have been several scientific tests on air purifier and ionizer, and they have not shown promising results. 

Most air ionizers have shown no noticeable change to the number of floating particles in the air. Most ionizers are too weak to have any effect on your air. 

It is important to note that these studies have shown that very strong ionizers affect the particles in the air like dust mites. However, the ionizers in these tests are much stronger than the ionizers in your average ionizing fans. They are also much stronger than any ionizer available for sale.

Do Ionizers Kill Viruses?

With the recent pandemic of the Coronavirus, you are probably wondering if the ionizer on your fan can kill viruses. When appropriately used, ionizers can reduce the number of airborne virus particles in your home or small office space.

However, an ionizer by itself is not enough to protect you from any virus, the Coronavirus included.

Are Ionizing Fans Bad for You?

Ionizing fans are not dangerous or bad for you to use. They do not create enough ozone generator for it to be damaging to your health. Any ozone they do create will disappear quickly because it is being blown away by the ionizing fans. 

Ionizing fans have a very tiny needlepoint ionizer that ensures little to no ozone generation is released into the air. These ionizing fans are not considered an ozone generator, and if any negative ions is released, it will dissipate within 30 minutes.
