We all know just how important it is to have clean fresh air in your home. That’s why many people consider purchasing air purifiers to keep the air in their homes clean.
However, what most people aren’t aware of is that air purifiers can actually pose a different type of risk to one’s health. Some air purifiers put out EMF radiation at levels that are considered to be unsafe.
Luckily, some brands of air purifiers do not put out nearly a much EMF radiation as the others, so today we are going to be taking a closer look at those.
So what are the best low EMF air purifiers? We recommend finding an air purifier that contains HEPA filters since those types of filters are able to remove up to 99.97 percent of indoor air pollutants. Ensure that the design of the air purifier results in low EMF emissions, best tested with an EMF meter.
Let’s go over the pros and cons of having an air purifier, as well as which ones put out the least amount of EMF radiation.
Why Use An Air Purifier?
First of all, you may be wondering if you even need an air purifier at all. The short answer to this is that you more than likely would benefit from one.
Air purifiers are really great products that help filter out dust and allergens from the air that would normally be circulating freely throughout your home.
We may not think that the air in our homes is really that unclean, but you would be surprised at what many studies have found.
There’s been a lot of research into this that says that the air inside of our homes can be much more harmful than the air outside at times.
According to the United States Environmental Protection Agency (EPA), the air inside of our homes can be up to five times more polluted than the air outdoors.
This is because the air that’s inside of our homes is not circulated as much as the air that’s outside. There’s no wind to carry off harmful pollutants and bring in the fresh air.
Since the air isn’t circulated, many of these pollutants are able to stick around and thrive within the home. An air purifier can help keep the air in your home circulating more often and mimic the role of what wind would normally do.
Air purifiers work to refresh stale indoor air and reduce the chances of your family developing health issues due to a lack of clean air.
Some of those potential health impacts include respiratory infections, neurological problems, or increased symptoms in those who already suffer from asthma.
If you have a good quality air purifier, you reduce the risk of developing these negative health effects.
A good quality air purifier with HEPA technology filters should be able to remove up to 99.97 percent of airborne pollutants in your home.
By removing this much of the pollutants in your home you should be able to notice an immediate impact on the quality and freshness of the air as well as benefit from many long-term positive health improvements.
Benefits Of Air Purifiers
Having clean air inside of your home can give you a better quality of sleep (which we know is critical for overall good health), and can even increase a person’s life expectancy.
For those who have asthma, having an air purifier can improve and reduce the severity of asthma-related symptoms. People dealing with asthma have inflamed bronchial tubes.
Indoor pollutants that can cause the bronchial tubes to become inflamed also include hair, dust, and pet dander, all of which tend to float around and linger in the air of homes without air purifiers.
Reducing the pollutants within the air can in turn reduce the amount of inflammation in the bronchial tubes, and reduce the overall symptoms a person with asthma would normally experience.
The good thing is that most air purifiers on the market do contain HEPA filters that are designed to capture all of the aforementioned air pollutants so that you can breathe fresh, clean air inside of your home.
Having an air purifier can also cut down on the spread of cold and flu viruses. These are airborne diseases that can linger around in the air of your home.
That’s why in most cases when one member of the family gets sick, some of the other members of the household end up getting sick as well. There’s a higher likelihood of this happening if everyone is breathing in the same uncirculated air.
Air purifiers are able to capture these harmful bacteria and viruses and prevent them from recirculating into the air of your home. When you remove the number of bacteria and viruses in the air, you reduce the likelihood of your family getting sick.
This is especially important for those who live with children, elderly people, or anyone with a weakened immune system.
Why Indoor Air Pollution Is Dangerous
Indoor air pollution not only has an impact on your respiratory system but your cardiac system and the neurological system as well.
Chemicals and gasses that are emitted from common household cleaning products can accumulate in the air in your home and enter your body as you breathe them in.
The airborne particles are so small that they can penetrate the blood-brain barrier and have a negative impact on your brain and cognitive functioning. This can lead to issues such as developing Alzheimer’s and other neurological diseases.
It can also can a decrease in your overall life expectancy. Having a good quality air purifier can help trap these particles, providing you with better air quality, and improving your life expectancy.
How Do Air Purifiers Emit EMF Radiation?
First, we have to remember that there is more than one kind of electromagnetic field, in fact, there are 3: electric field, magnetic field, and radio frequency. All three kinds are a form of EMF radiation.
On this site, I often find myself talking about radio frequency (RF) radiation because that is what is emitted with things like cell phones, WiFi, 5G, and much more.
Although some modern home air purifiers are now coming out with “smart” features that let you control them wirelessly (and thus would emit RF radiation) most do not have this feature, and therefore only emit electric and magnetic field radiation.
To put it simply, air purifiers emit EMF radiation from their electrical motor. This is the motor that powers the unit. The electric motor is powered by an alternating current which is used to turn the fan and move the air while cleaning it.
An electric board is what regulates how much power is applied to the fan which is how different fan speeds are possible. Both the motor and the process itself generate EMF fields around the unit when in use.
This is the case for all air purifiers, however, there are some that emit less EMF radiation than others, and this is what we’re going to focus on.
How Much EMF Radiation Do Air Purifiers Emit?
The amount of radiation emitted from air purifiers varies quite wildly, and unfortunately, unlike cell phones that have to report the radiation levels emitted (see SARs), air purifier companies do not have to report these numbers.
Some people have taken it upon themselves to test air purifiers out, such as one gentleman who wrote about his experience on a tech forum. He tested three different models, and all three maxed out the magnetic field readings of his meter (at 200 mG). Even at 2 feet away, he found that they emitted up to 63 mG of radiation.
Now, we had an air purifier at home, and I tested it myself with various meters and found that at the closest possible distance, it emitted far more than this, upwards of 500 mG, which is far above safe limits.
Now, there is no circumstance in which you would have your body touch an Air Purifier for long periods, and the radiation levels fall off pretty quickly with distance.
So, if you do have an air purifier, and you're worried about the emissions, just be sure to leave it in the corner of the room away from where you spend the most time and this should reduce your risk some.
In addition, you can use this list to find great air purifiers that also emit lower levels of EMF radiation.
The 5 Best Low EMF Air Purifiers
Now that we’ve gone over why you might want to use an air purifier for your home, let’s talk about which ones are the safest to use.
As we mentioned, not all air purifiers are created equal when it comes to safety. Some of them emit higher levels of EMF radiation than others.
When looking for a new air purifier for your home, you’ll want to look for one that puts out the least amount of EMF radiation, which can be just as harmful, or more on your health than the issue of having unclean air.

Here are a few of the top related questions that I wanted to quickly cover.
If I didn't answer your question here, please feel free to comment below and I'll do my best to help!
Where should I place my air purifier to reduce EMF exposure?
Place the air purifier in a corner or an area away from where you spend the most time.
EMF radiation decreases significantly with distance, so positioning the unit a few feet away can further minimize exposure.
Try not to place the air purifier near your head or body, especially in places that you'll be sleeping or spending long periods of time.
How do I know if an air purifier emits low EMF radiation?
Look for air purifiers that are marketed as “low EMF” or have been independently tested for EMF emissions.
Check the manufacturer's specifications or test results, and opt for models with lower electric and magnetic field readings.
Or, get a quality EMF meter and test the air purifiers yourself.
If this is the route you want to go, I'd recommend reading my article on the best EMF meters, and then once you have one, take a look at my article on What is a High EMF reading, as it will guide you through testing devices yourself.
Do low EMF air purifiers use smart features like Wi-Fi or Bluetooth?
Most low EMF air purifiers avoid smart features like Wi-Fi or Bluetooth to reduce radiofrequency (RF) radiation.
If you’re concerned about RF exposure, choose a model that has just the essential functions, and avoid all the smart features and connectivity.
