What Does Ion Mean On A Fan?

A fan is a pretty simple device. It blows air and it osculates.

It has very few working parts aside  from what speed to run it on,

and a lever to keep the air moving in one direction or going from side to side across a wider area.

But once in a while you’ll find something you’re not used to looking at on the fan.

And that’s something in this article is an ionizer setting.

What Does Ion Mean On A FanWhat does ionizer mean on a fan?

Ion stands for ionizer or negative ion generator. an ionizer on a fan is there to help clean the air as it is cooling the air.

Ionizers emit negative ions into the air stream as a means of purifying the air of contaminants such as pollen, pet dander, dust mites, and mold spores, etc.

How does an air ionizer work?

Polarity. When negative ions are emitted into the air, they automatically,  through polarity, attract the positive ions in the air.

When the negative and positive ions snap together to become one,  they trap whatever pollution that is present in the air together with them into a cluster of ion’s and airborne pollutants.

This newly-formed particle is too heavy to float so as a result, it falls to the surface and out of the ambient air that you breathe. 123 knockout.

The Lasko Ionizer Fan

is the most popular fan with an ion setting. Nice fans. You can check them out here.

Negative ions also have the reputation of creating a freshness in the air. There are even claims that having an overabundance of negative ions in a room can create a feeling of well being.

The atmosphere that an overabundance of negative ions create can be compared to the after a thunderstorm feeling where everything is light and calm.


Negative ion generators are notorious for leaving the area around the ionizer dusty.

There is a term for it. “Grey wall syndrome”.

Because the walls tend to get the brunt of it.

Also anything that is already magnetized with static like a TV screen will attract the newly-formed dust particles more heavily.

And also the ionizer itself also can get super dusty. Which adds to the point that not only will you need to dust more often to keep the dust down, the ionizer will be less effective if it’s not kept clean so that the ions can freely leave the machine without being obstructed.

Are ionizing fans bad for you?

Ionizing fans are not dangerous because they do not create enough ozone to be so. And any ozone they create, dissipates quickly because it is blown away by the fan.

Ionic purifiers or ionizers are also notorious for creating ozone as a by-product.

You may have heard someone say or even said it yourself, that the air purifier has a weird smell. That smell is probably ozone.

If you haven’t seen it yet“, the
Clarifion Portable Plug-in Travel Air Ionizer
is a pretty sweet gadget that is getting a ton of great reviews.
You can see it here.

What does ozone smell like?

Ozone is said to have a fresh, after a thunderstorm scent. But some have described it as a pungent, antiseptic smell, similar to bleach.

Ozone oxidizes practically anything it comes in contact with including lung tissue. That is why it is dangerous to breathe substantial amounts of ozone.

Ionizers have been called out by the EPA because even though most create a very low level of ozone, even a small amount of ozone that is not regulated by making sure the level of ozone is compatible with the room size can be dangerous.
And since you cannot regulate how a consumer uses an ozone device once they have it in their possession, it poses a risk.

Ionizing fans have a very small needlepoint ionizer that creates little to no ozone. The machine is in no way considered an ozone generator and the product specifications do not indicate any level of ozone being created.

Ozone at a large level will dissipate on its own in about 30 minutes. And that’s without a fan.

With a fan built in, like on an ionizing fan, ozone does not have any chance of sticking around at any level that can be considered dangerous.

Verdict: Ionizing fans are safe to use.

Do fan ionizers really work

Do fan ionizers really work?

Unfortunately fan ionizers are limited both as a fan and as an ionizer.

They are limited as an ionizer because:

1. Ions have a very short shelf life. They dissipate very quickly.

Ionic air purifiers usually do not come with a fan or if they do it’s a very small fan comparable to the fan on a computer.

Generating negative ions and then blowing them across the room with a regular sized fan is not a technique that works for spreading delicate ions through an area.

Most will dissipate very fast when the fan hits them and do very little good to rid the air of contaminants.

Negative ion generators work best at cleaning the air directly around the air machine. Most do not recommend trying to clean an area more than a hundred or a 150 square feet. And that’s the absolute optimal.

That is one reason why personal wearable ionizers are popular because they ionize the air directly around your face and mouth. They are very small and meant only as a means of purifying the air directly in front of your face so that you are breathing in clean air.

 AirTamer A310

is the leading personal wearable air purifier on the market using cutting-edge technology to emit negative ions and push pollutants away from your breathing zone. See Reviews Here.

2.  Ionizing fans do not work great as a fan either because the lower speed settings are slower than typical standing fans to try to accommodate the short life of ions.

But even as at lower speeds, as stated before, ions dissipate much too quickly for a tower fan to work well as an ionizer,

And the lower speeds make the fan less effective at cooling air.

My opinion is that some technologies do not work particularly well together and two of those technologies that maybe should not be paired are ionizers and standing fans.

In both cases it would be much better to pick a machine based on its strengths.

There are some amazing air purifiers that clean up to 99% of airborne dust, pollen, dander, dust mites, odors and even viruses.

Likewise there are some really awesome fans available; they can create layers of airflow one upon another and effectively move across a large area without too much noise.


There are different settings on a fan that you may not recognize off
hand. The ion button may be one of them.

The ion button on a fan is there to engage a negative ionizer feature.

Ionizers are devices that clean the air by emitting negative ions. And through polarity creating dust particles that are too heavy to float.

Unfortunately the nature of ions as being very delicate make the use of an ionizing fan less-than-ideal for not only cleaning the air but for cooling the air either.

Though there is no danger posed by using the ionizer on a fan, there is also only a minimal amount of benefit that you can get from using an ionizer on a standing fan.

Air ionizers and tower fans are not two devices; they can be paired together to make a better machine.

My advice is to pick an air purifier based on its performance for cleaning air and pick a fan based on its performance for moving air and never the twain shall meet.

What Is an Ionizer Fan?

When you’re talking about a fan ionizer, you have to differentiate between a fan that has an ionizer feature and an ionizer that uses a fan. Also closely related to those is an air conditioner ionizer.

These are all very closely named products that make it very easy to get confused about what is what and what they do.

So let’s break it down a little bit.

What Is A Ionizer Fan?

A Ion fan or a fan ionizer is generally a tower fan that has a ionizer feature included.Its primary function is to blow and cool the air like any other fan but it comes with a small brush ionizer that can emit negative ions into the air while the fan is running. An ionizer with a fan is an air ionizer purifier that includes a fan as a means to help move ions further into a room. Its primary function is to clean the air in a room and it does nothing to cool the air.

Air Conditioner ionizer

An Air conditioning ionizer is an air purifier that goes inside of your HVAC air conditioner.

Its primary function is to clean the air inside of the ductwork and use the HVAC as a whole house air purifier.

How an ionizer works.

An air ionizer removes pollutants like bacteria, pollen, and odors from the air by adding a negative charge to molecules.

When emitted into the room, because of polarity, the negative molecules or ions attract the positive molecules (the pollutants in the air).

Then the newly-formed cluster of combined negative and positive ions become too heavy to float and fall to the surface.

This leaves the Ambient Air free of contaminants to breathe easier

but it also leaves the surfaces around the air purifier dusty.

Whether you have an ionizing fan that includes an ion feature or you have a air purifier ionizer, the premises the same. But the capacity to clean air between the two differs drastically.

Have you ever wondered what the ion setting on a fan is?

It is a button that activates a small ionizer or ionizing wire that is meant to clean the air as it’s blowing from the fan.

Does a fan with an ionizer work?

Yes but not very well. The reason is that negative ions have a very short life span  and need to be eased into the air rather than full-on blown.

A typical room fan is likely to cause the ions to dissipate much too rapidly before they have a chance to clean the air very well.

Compare that to a air purifier ionizer

A air purifier ionizer only has a couple of settings. Fan or no fan.

And the fan is very small and more like the fan on a computer than a fan that is meant to cool off a room.

Ionizers work best as simple negative ion generators that let the ions move at their own pace. Gradually making their way out into an area as a path is made.

When a fan is used on an air ionizer, it is there to help give the ions a little push to get a little more square footage out of a machine.

Cooling the air and cleaning the air are not the same thing and combining the two does not give the best results.

I honestly think that it is much better to use a fan to cool the air and a separate purifier machine to clean the air in a room.

Are ionizing fans bad for you?

All ionizers create negative ions through either electric spark or UV which causes a small amount of ozone to be created in the process.

The ionizer on a tower fan creates a very low amount of ozone, and then the fan blows it away on the spot. Ozone dissipates very quickly and with the fan right on it, it doesn’t have much of a chance to be a hazard.

I have yet to see a tower fan with an ionizer, that list any warning in their instruction booklet, or give any actual quantity to the amount of ozone being created by the ion feature.


An air purifier ionizer with a fan has a much larger chance of creating enough ozone to cause discomfort or irritation to your breathing.

Since the primary function of an ionizer is to create negative ions, the likelihood of ozone buildup is much higher.

Most ionic air purifiers create much less ozone than what is allowed by the EPA.

But not all  ionic air purifier manufacturers follow the guidelines perfectly.

Ozone can build up and you should be aware of it.

Ionizers that are too strong should be treated more like an ozone machine that is meant to be operated when there is no one around. That includes pets.

Many ionic air purifiers have a “while you’re away” setting.

That is another way of saying that the setting is there to create a higher level of ozone and you need to be out of the house or office when it is in use.

Also set a timer to turn the machine off a hour or so before you’re going to be home to allow the ozone to completely dissipate before you get there.

Air Conditioning Ionizer

Have you ever wondered what an ionizer on a AC is?

An air conditioning ionizer or induct air purifier is made to be placed into the ductwork of your HVAC system.

The ideal is that the inside of your ductwork is full of bacteria and germs, as well as dust mites.

By placing ionizers in the ductwork, you clean the air before it ever has a chance to distribute the contaminated air into your Home or business.

This is the safest and most effective way to get a whole house air purification effect out of a ionic air purifier.

Are ionizers good for you?

An air ionizer used in the right way can be a great benefit to your health.

not only do they clear the air of harmful contaminants,

They create a atmosphere of freshness that can have an energized and relaxing affect on your mood.

Are ionizers bad for you?

Though ion machines have some great benefits when they are used correctly, they also have their ugly side when their not.

Ionizers are meant to be used for the exact square footage they were purchased. Placing an ionizer that was meant to cover 300 square feet in a closet will create way too much ozone for the area.

This is the reason to EPA discourages the use of ionizers as an air purifier.

And also one of the reasons why California has banned the sell of air cleaners that create ozone as a byproduct.

Ionizers that create too much ozone should just be labeled ozone machines or ozone generators and be happy about it.

Why would you try to sell me something that’s going to be potentially dangerous when you could tell me right out that I should only use it when I’m out of the house?

If you need an air purifier to sleep with, there are types of air purifiers that use no ozone and would be a better choice in that type of situation.Also you can keep a fan on you while you’re sleeping and not affect the capacity of the air cleaner at all.

20 Ways to Lower the Humidity in Your House

Are you wondering how to lower the humidity in your house? You are not alone, as a lot of people feel a sense of discomfort and unhappiness when they deal with super high humidity levels. And that’s why it makes a lot of sense to find new, creative ways to lower home humidity as quickly as possible. With that in mind, here you have a few tips that will help in this situation.

1.Use a dehumidifier

A dehumidifier is one of the simplest tools you can use to keep the humidity levels as low as possible. It’s highly recommended to invest in a good dehumidifier since it allows you to ensure proper airflow circulation, all while eliminating any humidity from the air. Ideally you want to keep the unit away from furniture or any walls, unless it has air vent on the top.

2. Clean the downspouts and gutters

You want to do this because they will carry water away from your home. It’s a good idea because if you don’t do this, you will end up with high humidity levels in your home. Plus, it’s a good idea to restrict watering plants to bare necessities, just to be safe. The more restrictions you have in this situation, the better it will be as you do want to avoid complications.

3. Keep fresh-cut firewood outside

Why is this important? The most important aspect to consider is that freshly cut firewood has large amounts of water in it when you store it indoors. You want to leave the firewood outside so all that water will evaporate. If you don’t do that, then you will increase the humidity levels inside. Even if it doesn’t feel like a lot, in a situation like this, every little thing counts, so you might as well want to take that into consideration just to be safe.

4. Bring all your plants outside

Don’t keep plants indoors. They end up increasing the humidity levels and that’s the type of thing that you want to avoid. Ideally you want to keep them outside and you will be just fine. You could also keep them in a single room, however that room will have lots of humidity, so you really need to figure out what works for you here.

5. Keep the AC drip pans and drain lines clean

If you keep them clean and unobstructed, it will be a lot easier to avoid any humidity issues. The AC will remove all the humidity from your room. However, if the AC is not working properly, then you will have issues with this approach. You need patience to do this right, but it will be worth it.

6. Vent your clothes dryers outside

The reason you want to do that is that you end up generating a lot of humidity if you do this inside. There’s no real benefit coming with performing this activity inside anyway, so you have to figure out what works for you and how you can adapt to the entire process.

7.Add double-glazing to your windows

When you do that, you will have less humidity and that on its own can be a very important aspect to consider. Double-glazing really brings in front great results, and the best part is that you can avoid severe condensation without spending a whole lot of money. It’s the best of both worlds and you should totally check it out.

8.Aerate your attic and basement

Normally these are two of the places in your home where you will have a lot of moisture. If you start bringing in fresh air in there, you will start removing more and more moisture naturally. It’s one of the best approaches you can have and it does work really well if you do it right. We recommend you to test it out and perform this task often to avoid moisture and dampness in your home.

9. Use a fan in your kitchen

If you cook often, you will generate humidity in your kitchen. It makes a lot of sense to use a fan or anything that will bring in fresh air and push the humidity away too. This is an important aspect to think about, and it will offer you a very good experience every time. In a situation like this, you need to start easily, and this approach does make a lot of sense.

10. Open the fireplace damper

The fireplace damper allows you to push moisture away from your room. It’s a good way to lower the humidity naturally, and we believe that you should always consider it as one of the first things you can do when you deal with lots of humidity inside your home.

11. Open up the windows

This is simple, but it helps you push humidity away, all while bringing in dry air from outside. You have to figure out what approach works for you, and it all comes down to delivering the best results and having the right approach here.

12. Cover your food while cooking

Another interesting thing to do when you are cooking is to try and cover the food. This will keep the humidity under control. Alternatively, you could use a slow cooker, which brings pretty much the same experience and great results you would expect. It’s always a good idea to find alternative solutions, and it can be very well worth the effort all the time without any worries.
Lower your Humidity

13. Take cold, short showers

Hot showers will generate steam and that will obviously increase the humidity levels in your home. Not only that, but if those hot showers are long, then you are further increasing the humidity levels. You need to pay a lot of attention to this, because the more you take hot showers, the more humidity you are generating within the entire home.

14.Replace the carpet if it’s a model that retains moisture

Some types of carpets like the fluffy or very thick ones tend to retain a lot of moisture. They will also end up capturing dust mites and bacteria. It makes a lot of sense to replace your carpets with simpler ones. Make sure that you go with carpets that are not going to retain any moisture. And if you do that properly, it will be more than ok.

15.Add wrap or tubular insulation

Insulating tubing works great for the cold water pipes. It will help decrease sweating, and the best part is that you will have less humidity in your home. Even if it seems like a simple thing to do, it will make quite the difference.

16. Repair the door and window frames

When you have issues with the window and door frames, the first thing you want to do is to repair them. These frames can bring in moisture into your home, and that’s the last thing you want to have. Even some simple repairs can make quite the difference, and all you need is to give these a try, it will be well worth it in the end.

17.Insulate the crawl spaces

The best method you can use for insulating crawl spaces is through using a plastic vapor barrier. This is not that hard to do actually, and it will bring in front some pretty impressive results. The idea is to know how to perform proper insulation, and if you do it right, it will be a very good experience.

18. Waterproof the concrete basement walls

Waterproofing these walls will be a major way to deal with excess humidity. Most of the time concrete walls will bring in humidity to your home. That’s why waterproofing them is so important, and you should treat this as a priority to avoid any possible problems.

19. Treat the foundation with Hydroclay

Hydroclay is known for waterproofing tunnels. It’s a water-absorbing clay, and it will seal the basement where you have water infiltrations. Waterproofing your foundation with this will make quite the difference, and it will help you keep your home safe. Plus, you get to deal with humidity the right way, and that on its own can deliver quite the difference.

20. Vinyl wallcovering

Using vinyl wallcovering can be a very good idea. The trick here is that this type of wallcovering will help trap the moisture and basically keep it out. If you ignore this, it will lead to mold growth. So that’s certainly something to keep in mind.


It’s very important to find great, creative ways to keep the humidity levels as low as possible within the entire home. If you have low humidity levels within your home, you will breathe better, your skin will feel better, and you will have a great sense of well being. It’s important to take all of this into consideration, and the results can be very good every time. If you still have high humidity levels within your home, it’s a very good idea to hire a professional and solve this issue!
