What Does an Ionizer Do On a Tower Fan? 

A tower fan is sometimes necessary to keep a moderately small area cool.

However, what good is a fan when it keeps you cool but continues to blow around all the impurities in the air around the room?

This is why many tower fans nowadays include something called an Ionizer.

So, what does an Ionizer do on a Tower Fan?

Ionizers emit negative ions, which sounds bad but great for us. They do this by electrically charging the air molecules through the electrically charged wire inside the ionizer, thus creating negative ions.

Negative Ions help to purify the air by capturing even the most minuscule of contaminants, including pollen, mold, soot, dust, pet dander, and even odors, viruses, smoke, and chemical toxins.

Thus, a tower fan with an ionizer is aimed at those with any allergies, asthma, or chemical sensitivities. The ionizer unit is located within the fan. In addition to the purifying benefits these charged particles provide, they have also been found to reduce static electricity, fight fatigue, and improve overall mood.

We take in negative ions by large bodies of water while in the mountains or showering.

However, the possible contaminants in our everyday tap water may offset the benefits of the negative ions you receive while in the shower.

They have also been shown to improve sleep quality, decrease stress levels, and relieve symptoms of depression.

The negative ions released from Ionizers contained in tower fans also help to counteract the actually negative effect that positive ions can have on our health. Positive Ions are emitted from computer monitors and Wi-Fi signals, vehicle fumes, and more.

They alter our brain waves, produce feelings of fatigue, cause an increase in hypertension, and have a harmful overall effect on our health and, therefore, our moods.

When the negative ions released from the ionizer come in contact with the positive ions in the air, such as bacteria, dust, pollen, smoke, and other allergens, the two kinds of ions bond to one another, forming dense particles of dirt that cannot float in the air.

These heavy dirt particles drift to the ground to be swept up or vacuumed away, stick to surfaces within a room to be dusted away, or collect on an electrically charged collection plate near the ionizing system.

Though ionizers sound amazing, it is worth noting there seems to be conflicting information on whether they are beneficial, and often, people may not notice any tangible difference. Some ionizers produce ozone, which is detrimental to your health, so be sure to check if your tower fan ionizer does or not, and check out our guide to the best tower fan.
