Can Air Purifiers Cause Headaches? Find Fact!

There are plenty of things that can cause you to experience headaches, including allergies, stress, sinus infections, and even poor sleep quality. 

Can air purifiers cause headaches?

Yes, air purifiers can cause headaches. This happens when the machine is over-purifying the air in a room and causing airborne irritants called VOCs (volatile organic compounds) to build up. These VOCs can cause allergic reactions as well as headaches.

Air purifiers are usually used to clean the air in your home or office. But have you ever wondered if the air purifiers can also cause headaches and migraines?

According to an article by The New York Times, air purifiers can be one of the causes of headaches. In this post, we’ll look at how air purifiers can actually contribute to the problem. 

We’ll also explore how air filters can help improve your health, along with the potential hazards of using them. So, whether you’re thinking about getting one, or are already using one, read this post for all the details.

How can you tell if air purifiers can cause headaches?

Air purifiers can cause headaches, but it’s rare. They can cause headaches if the purifier is too powerful for the room you are trying to clean. 

If you find yourself getting headaches from your air purifier, then try moving it closer to a window where more fresh air will enter the room.

Air purifiers can cause headaches in some people. If you’re feeling lightheaded or getting headaches, it could be a sign that you’ve got an air purifier that’s too powerful for your home. 

People with allergies that are sensitive to dust or pollen may find that an air purifier aggravates their allergies and can get headaches from the air purifier.

Some people have reported getting headaches when they use air purifiers and while the scientific studies are inconclusive, it’s still good to be aware of this possibility.

Why does an air purifier cause headaches?

There are a few reasons why air purifiers could lead to a headache.

  1. The first is because of the sensitivity of your nose.
  2. Your sense of smell is closely linked to your sense of taste and if you’re sensitive to certain scents, then you might be sensitive to the scents that air purifiers emit.
  3. Some of the most common sources of indoor air pollution are things like fragrances, insecticides, and air fresheners. This is because they contain volatile organic compounds (VOCs) that can irritate the eyes, nose, and throat.
  4. When you first bring an air purifier home, it’s normal to experience some symptoms such as headaches, dizziness, and nausea. This is because after removing the pollutants from the air, it may seem like there’s not enough oxygen in the room. As your body starts getting used to the cleaner air, these symptoms should disappear.
  5. Many air purifiers have a strong fan to push the air, which can cause headaches if you’re in the room for too long.
  6. The other main reason people experience headaches from air purifiers is due to the smell of the purifier.
  7. In the process of removing volatile organic compounds, an air purifier releases small amounts of ozone. Ozone is a compound made up of three oxygen atoms, instead of the two in the oxygen we breathe. This extra oxygen atom makes ozone very reactive.
  8. Another reason why an air purifier can cause headaches is because of the technology that’s used in the device. Air purifiers work by using a fan to blow air through a filter. The filter contains activated carbon, which absorbs compounds like odors and volatile organic compounds.
  9. An air purifier that is being used to help someone with allergies or asthma might make them feel worse. This is because the air purifier will suck up some of the allergens or pollution in the air and then release them back into the room. This can cause a build-up of allergens and make someone feel worse in the long run.
  10. An air purifier can cause headaches if it leads to a stuffy nose or changes the temperature of the room. If the air purifier is too close to a person’s head, it may change the temperature and humidity levels in the room. This will cause the air to become stuffy which can lead to headaches.

How to know whether an air purifier should be used?

It’s important to note that not all air purifiers work the same. Some are meant to remove dust, while some others are meant to remove odor. Before you invest in an air purifier, it’s important to find out what kind of air purifier you need.

The Environmental Protection Agency reports that indoor air pollutants can be up to five times higher than outdoor pollutants.

The most common pollutants in the home are dust, dander, mold spores, and pollen, according to the EPA. Allergens, bacteria, and odors are also common culprits. So when you feel difficulty breathing it’s time to use an air purifier. 

Also, the easiest is to look at the air quality in your room. If it’s bad, then you need an air purifier.

How do you use air purifiers effectively?

First of all, you want to make sure you get a HEPA filter. A HEPA filter stands for High-Efficiency Particulate Air. These filters have a very dense weave, which allows them to remove more particles from the air than typical filters.

Then you should find out if your air purifier has a timer function that automatically turns the machine off. If it does, you should set the timer to turn it off after a couple of hours at night, so it doesn’t bother you as you sleep.

For an air purifier to be effective, you must pay attention to the size of the room you’re trying to deodorize. 

You need to know how much square footage you have and get an air purifier that is appropriate for your space. Also, air purifiers need to be replaced once every year or two because the filters become less effective over time.


Air purifiers can be very useful in many homes. But it’s important to understand the risks and side effects of air purifiers before you decide to buy one. Having learned that air purifiers cause headaches, we should seek and implement ways to alleviate them.

Also, make sure to choose the right air purifier for your needs. The right air purifier will not only make your life better, but it will also help you save money in the long run.
