Air purifiers are important home devices for many people because they help to filter out dangerous airborne pollutants and aggravating allergens. However, most air purifiers also give off small levels of EMF radiation.

Many people want to know whether or not EMF is dangerous and whether or not it will impact their overall health. The short answer is that low levels of EMF radiation are safe and air purifiers are safe. The Internet is filled with misinformation about EMF radiation, so we will cover that today in our air purifier guide.

EMF radiation stands for electric and magnetic field radiation. EMF radiation can be safe and can be dangerous. Exposure to high levels of EMF radiation is hazardous and should be avoided because even short-term exposure can have disastrous consequences. Low forms of EMF radiation, however, are safe.

For example, you can find low levels of EMF radiation in many household appliances such as microwave ovens, WiFi routers, and cellphones, as well as power lines. Most air purifiers actually use only 12-55W of power and create very little EMF compared to these other household appliances.

  • Electric field
    An electric field is one part of EMF radiation. Electric fields occur due to power voltages. The strength of the voltage is determined by the volume. Higher voltages are stronger. Home appliances have both an electric field (voltage volume) and a magnetic field (current/charge flow).
  • Magnetic field
    A magnetic field is the other part of EMF radiation. Magnetic fields occur due to the current or the charge flow. The more powerful the current is, the stronger the magnetic field will be. Some of the home appliances that have both electric fields and magnetic fields are air purifiers, electric razors, vacuum cleaners, TVs, clocks, fridges, and washing machines.
  • Radio Frequency
    Radiofrequency is a low-energy form that uses radio waves. Cell phones and WiFi are two examples of radiofrequency radiation. Radiofrequency radiation can also be found through the sky and the sun. Microwave ovens also use radiofrequency radiation. This frequency is safe because it is a low level form of radiation.

Do Air Purifiers Give Off Radiation & How Much?

Air purifiers can emit low levels of EMF radiation. Whole-house air purifiers give off EMF radiation and give off low levels of EMF; however, air purifiers with ionizing components or ozone-generating air purifiers give off higher levels of EMF radiation. If you are concerned, we recommend sticking with a HEPA filter air purifier without ozone generation.

According to the EPA (Environmental Protection Agency), the recommended level of EMF radiation is between 0.5 mG to 2.5 mG. You may have to contact the air purifier company directly if you want to find out the EMF levels. Why? Most manufacturers do not advertise these levels on their packaging.

One of the best ways to protect yourself from EMF radiation is to position your air purifier in a corner room. EMF radiation falls off dramatically within as little as two feet. If you can manage to stay more than two feet away from your air purifier throughout the day, then you will dramatically reduce the amount of EMF radiation you receive from your air purifier.

This is also true of other electronic devices that you possess. This is why bloggers often point to keeping your phone on the opposite side of the room to lower your EMF radiation levels (even though the EPA and WHO have said that cell phones are in the lower, safe limits of EMF levels).

Can EMF Radiation Make You Sick? 4 Known Symptoms

EMF radiation can affect the human body, but only at high levels. High-level exposure to EMFs comes through the sun and x-rays. The best way to protect yourself from sun EMFs is to wear sunscreen and spend time indoors during the midpoint of the day. The best way to protect yourself from x-ray EMFs is to limit the number of x-rays you get.

The American College of Radiology recommends that people have no more than 100 mSv of radiation exposure from x-rays throughout their lives. This comes down to approximately 10,000 x-rays but only 25 CT scans. If you experience the following EMF radiation symptoms, we recommend limiting the EMF appliances in your bedroom and living room. We also recommend setting EMF appliances 2-5 feet away from where you spend most of your time.

Affects sleep

High levels of EMF radiation can affect your sleep. The primary problem is that EMF has the ability to alter your circadian rhythm, and this leads to a lack of quality sleep. If you find your sleep affected, try moving your air purifier to the other side of the room while you sleep.

Affects mood

High levels of EMF radiation can affect mood by altering neurotransmitter function when it comes to serotonin and dopamine, two neurotransmitters responsible for mood and memory. However, studies have shown mixed results on long-term effects, with some studies showing slight disruptions and other studies showing no negative effects.

Affects attention

When exposed to high levels of EMF radiation, people can experience a lack of focus. This difficulty paying attention to daily life can be a symptom of EMF radiation. According to Science Direct, the amount of time students spent on the phone impacted their ability to concentrate. The longer they talked with the phone near their head emitting EMF, the harder it was for them to focus.

Affects fertility

EMF radiation has the ability to compromise fertility in both males and females. If you are trying to get pregnant, we recommend making sure that your air purifier is more than five feet from you during the day and at night.

Lowering your EMF radiation levels by keeping your phone a minimum of two feet away throughout the day is also a good idea. The further away from EMF radiation devices you can be, the better your chances of conceiving.

Are There Low EMF Air Purifiers?

Yes. There are low EMF air purifiers. These air purifiers, however, are not advertised as low EMF. Most of the air purifiers that we tested for low EMF fell below 2.5 mG when tested from 2-3 feet away.

The best way to find low EMF air purifiers is to look at the features that come with the model. Low EMF air purifiers will not generate ozone, for example, and they will also not be ionizing. Some air purifier models come with an ionizer setting, but as long as you do not use this setting, the EMF levels will remain low.

People Also Ask (FAQ)

What are some other common sources of EMF radiation in the home?

There are many common sources of EMF radiation in the home. If you have too many devices in your home, you may reach higher levels of EMF radiation, and that may have an effect on your health. However, most medical professionals agree that this cumulative amount would need to be quite high to have an adverse impact. The most common forms of EMF radiation are:

  • Cell phones
  • TV and radio
  • Microwaves
  • WiFi signals

Again, these EMF sources of radiation should emit low levels, which are not harmful to human health.

Do air purifiers emit low radiation?

Yes. Air purifiers do emit low levels of EMF radiation. If you are concerned, you can check the EMF reading of your air purifier to ensure it is below the EPA (Environmental Protection Agency) recommendation of 0.5 mG to 2.5 mG.

Can you filter radiation from air?

No. An air purifier will not filter radiation from the air. Low levels of EMF radiation exist in your home appliances and can safely exist in your air purifier as well, so this should not be a concern.

What is the first sign of too much radiation?

People who experience radiation sickness may experience fainting, confusion, and muscle weakness. They may also experience bleeding from the nose, gums, or rectum.

Radiation sickness most commonly develops when people go through cancer treatments that involve radiation. During a radiation cancer treatment, the body is given high levels of radiation that are not safe (but are designed to kill the cancer).

Which is better, an air purifier or ionizer?

Air purifiers and ionizers do different things for your home. Air purifiers are more effective at cleaning the air compared to an ionizer because they use HEPA filters (typically) and can remove smaller particles from your air.

However, ionizers tend to be cheaper. Ionizers will not remove chemical odors or gasses and have difficulty eliminating allergen particles such as house dust or pollen. Furthermore, many air purifiers come with an ionizer setting, so you can use both (ionizer setting would save you money throughout the day).

How can I test my home for radiation?

You can test your home for EMF radiation by using an EMF meter. These devices can be purchased online, or you can hire a private company to come in and test your home.


Air purifiers do not give off a dangerous level of EMF radiation. You can feel confident in purchasing an air purifier and bringing it into your home. If you are concerned, you can test the EMF radiation levels and ensure they are below the 2.5 mG recommended amount with an EMF meter.

You can also check the manufacturer’s information to see what level of EMF each air purifier gives off. Most air purifier units available today fall well below the EMF radiation level and will provide you with clean air at home.
