What does ion mean, anyway?

All it means is that the fan emits negative ions that then attach to positive ions in the air and works to neutralize them.

What Does The Ion Setting On A Fan Do?

Negative ions are beneficial to air quality because they reduce certain airborne irritants.

  • dust mites
  • gross smells
  • mold and mildew
  • pet dander
  • cigarette smoke
  • pollen

Clumps and Clusters

We’ve talked about how ionizing fans release negatively charged ions to trap impurities into clumps and clusters so that they will land on surrounding surfaces. 

  • carpets
  • floors
  • beds
  • shades
  • curtains
  • countertops
  • tables
  • shelves
  • ceilings (or shaky ceiling fans)

Once the particles have collected on those surfaces, you can wipe and clean them away.

Don’t just assume that the ionizing fan eats the bad stuff out of the air. You’ll have to do a little cleaning, or it will get swept back into the air.

Virus Protection

The helpfulness of an ionizer is likely over-exaggerated. But, in theory, ionizing the air does give some virus protection.

Some research shows that ionizers slow or stop viruses from growing. And they emit ozone that halts the spread in the air and on surfaces.

What is ozone?

You won’t find ozone in the periodic table, but it’s a gas released by ions with up to three oxygen atoms. Then, two particles attach for a moment, and the third drifts away.

It’s the free atom that does all of the work and cleans pollutants from indoor air.

But, many experts do warn against the release of ozone. It damages the environment and may have unknown long-term effects on humans.

Short-term side effects of ozone exposure can include eye, throat, nose, and lung irritation. If inhaled in high concentrations, it can even contract airways.

Do ionizer fans actually work?

Here is where it gets complicated – yes, and no.

In theory, ionizers emit negative ions that urge impurities to gather and stick to surfaces. But even the EPA concludes that fans with ion capabilities do little to reduce airborne particles.

You would need a huge air-ionizing fan to do the job that is often advertised. And, it would be insanely expensive and not energy efficient in the least.

Drawbacks 

Many fans come with the ion setting; in some cases, it’s a why not – a little help is better than some. But, there are cons to using the setting.

  • Ionizers don’t deal with certain pollutants like gas fumes.
  • It doesn’t work on large particles that affect asthma and specific allergies.
  • Ozone gas isn’t good for humans, especially for an extended period of time.

Maintenance

You’re not going to find a self-cleaning option on most fans. And, when particles clump and collect, it means they land on the fan and its components, too – including the ionization chamber.

Most ionizers don’t even use filters; when they do, you’ve got to clean them regularly. A dirty filter makes indoor air quality worse, not better.

Revisiting Ozone Emissions

The EPA hasn’t banned ionizers because they typically release as much ozone as an air conditioning unit. But that doesn’t mean they recommended running one for eight hours, either.

Ion Setting on a Fan: Risk vs Reward 

When you weigh the pros and cons, spending the extra bucks for an ion option is not worth it. It can affect your health, and it does damage the environment.

You’ve got options out there that purify the air far better.

Alternatives to Ionizing Fans

HEPA Filters

Honeywel HPA300 HEPA Replacement Filter R Compatible with Honeywell HPA300, HPA200, HPA100, HPA090 Series and HPA5300 Air Purifier, True HEPA Filter R (HRF-R3 & HRF-R2 & HRF-R1, 6 Pack)

  • A high-efficiency particulate air filter throws less dirt and dust mites into the air.
  • Reduces the allergens floating around.
  • A HEPA filter doesn’t release dangerous byproducts such as ozone.
  • You can find them in portable air purifiers, vacuum cleaners, and home air filtration systems.

Carbon Filters

  • Carbon filters are typically used in tandem with another filter.
  • The activated carbon air filters absorb better than the other options.
  • They capture gasses, smells, cigarette smoke, and most fumes.
  • Carbon filters don’t release byproducts into the air.

UV Light

UV light with electromagnetic radiation can work as an air filter. It breaks up pathogens so that the filters can kill certain particles using UV rays as they pass through.

  • Ultraviolet light destroys microorganisms – mold, bacteria, germs
  • The filter can help when preventing disease and sickness.
    • A UV light filter does not remove dust, allergens, gas, or cigarette smoke from the air.

Wrap Up

Pros of Ionic Filters

  • Air ionizing filters remove minuscule particles from the air.
  • It has the ability to sterilize smoke, viruses, and bacteria.
  • Ionic filters work quietly because they don’t have motors or fans.

Cons of Ionic Filters

  • Ionizing filters don’t remove particles and such from the air. Rather, it clumps them all together, so they fall on surfaces where you have to clean them. 
  • If you don’t clean surfaces after ionizing the air, you’re looking at quite a mess of dust, and the particles go back into air circulation.
  • Ozone is a dangerous byproduct that can harm humans and damage the environment.
