Can Air Purifiers Make You Sick?

Our Thoughts: From what we understand, air purifiers are designed to clean the air around us. They remove airborne particles like dust, allergens, smoke, bacteria, viruses, mold spores, pet dander, and airborne chemicals. By doing this, they can actually reduce our chances of falling sick from inhaling these harmful contaminants.

Air purifiers have been a hot topic in recent times, with a lot of mixed press surrounding them. This has led to a surge in questions like, “Can Air Purifiers make you sick?” or “Can it cause a sore throat, cough, headache, or even a nosebleed?” This article aims to dispel the confusion and misconceptions about air purifiers and their impact on health.

Understanding Air Purifiers

Air purifiers are devices designed to cleanse the air in your surroundings, making it healthier to breathe. They achieve this by eliminating airborne particles that can potentially cause illnesses. These particles include dust, allergens, smoke, bacteria, viruses, mold spores, pet dander, and airborne chemicals. By removing these harmful contaminants, air purifiers can actually reduce your chances of falling sick or developing an illness related to inhaling these pollutants.

The Role of Air Purifiers in Health

Air purifiers play a crucial role in maintaining a healthy indoor environment. They are particularly beneficial for people with allergies or asthma, as they can significantly reduce the amount of allergens in the air. A study by the National Institutes of Health (NIH) found that using an air purifier at home improved the overall quality of life for people with allergic rhinitis.

However, it’s essential to note that while air purifiers can reduce the concentration of airborne pollutants, they are not a cure-all solution. They should be used in conjunction with other methods of air quality control, such as regular cleaning and proper ventilation.

Can Air Purifiers Make You Sick?

Can Air Purifiers Cause Health Issues

While air purifiers are generally beneficial, there is one type of air cleaner that can potentially exacerbate existing respiratory conditions like asthma and Chronic Obstructive Pulmonary Disease (COPD). This is the “ionizer.”

Ionizers work by emitting charged ions into the air. These ions attach to airborne particles, making them heavy enough to fall to the ground and be removed from the air you breathe. However, these ions can irritate the lungs, causing discomfort for people with respiratory conditions. If you have such a condition, it’s advisable to avoid ionizers.

Types of Air Purifiers and Their Effects

Type of Air PurifierHow It WorksPotential Health Impact
HEPA FilterTraps particles in a complex web of fibersBeneficial for most people, especially those with allergies or asthma
IonizerEmits charged ions that attach to airborne particlesCan irritate the lungs of people with respiratory conditions
Activated Carbon FilterAdsorbs odors and gasesBeneficial for removing odors and gases, but not effective against particulate pollutants
UV LightKills bacteria and viruses with UV lightEffective against microorganisms, but not against particulate pollutants or gases

Will Air Purifier Makes Me Dizzy?

Will Air Purifier Makes Me Dizzy

Air purifiers are designed to clean the air by removing pollutants such as dust mites, allergens, and smoke. However, some people report feeling dizzy after using an air purifier. This could be due to several reasons.

If the air purifier uses an ionizer or produces ozone, it could potentially cause dizziness. Ozone is a type of oxygen molecule that can cause a variety of health problems, including dizziness, when inhaled in high concentrations. While most air purifiers on the market are designed to be safe and produce minimal ozone, some models may still produce it in small amounts.

If the air purifier is removing a large amount of pollutants from the air, it could cause a temporary increase in air quality that your body is not used to. This sudden change could potentially cause dizziness, especially if you have been living in a polluted environment for a long time.

The dizziness could be a symptom of an allergic reaction to something in the air purifier itself, such as the filter material or any chemicals used in the purifier. If you’re feeling dizzy after using an air purifier, it’s important to consult with a healthcare provider to rule out any underlying health conditions.

Do Air Purifiers Cause Cancer?

There is no direct evidence to suggest that air purifiers cause cancer. However, certain types of air purifiers that emit ozone can potentially contribute to the development of respiratory diseases, which in some cases could lead to cancer.

Ozone is a powerful oxidant that can cause damage to the lungs and respiratory system. Long-term exposure to high levels of ozone can lead to chronic respiratory diseases like asthma and COPD, and these conditions can increase the risk of developing lung cancer.

However, it’s important to note that most modern air purifiers are designed to be safe and produce minimal, if any, ozone. If you’re concerned about ozone, look for air purifiers that are certified by organizations like the California Air Resources Board (CARB), which sets strict limits on ozone emissions.

Can Air Purifiers Make the Air Dry?

Air purifiers do not directly change the humidity level in the air. They work by filtering out pollutants from the air, not by removing moisture. However, if you’re using an air purifier in a room with already low humidity, it may feel drier simply because the air is cleaner.

If dry air is a concern, consider using a humidifier in conjunction with your air purifier, or look for an air purifier with a built-in humidifier. Always ensure that the humidity level in your home is comfortable for you, typically between 30% and 50%.

Can Air Purifiers Cause Breathing Problems?

Air purifiers are generally beneficial for people with respiratory conditions, as they remove pollutants from the air that can trigger symptoms. However, certain types of air purifiers can potentially cause or exacerbate breathing problems.

As mentioned earlier, air purifiers that emit ozone can cause respiratory issues. Ozone can irritate the lungs and throat, leading to coughing, wheezing, shortness of breath, and other symptoms. If you have a pre-existing respiratory condition like asthma or COPD, exposure to ozone can worsen your symptoms.

Additionally, if the air purifier’s filter is not changed regularly, it can become a source of pollution itself. A dirty filter can harbor mold, bacteria, and other pollutants, which are then released back into the air.

If you’re experiencing breathing problems after using an air purifier, it’s important to consult with a healthcare provider. It’s also a good idea to ensure that your air purifier is properly maintained and that it does not produce ozone.


In conclusion, air purifiers are generally beneficial for health as they reduce the concentration of airborne pollutants. However, certain types, like ionizers, can potentially cause discomfort for people with existing respiratory conditions. Therefore, it’s crucial to choose the right type of air purifier based on your specific needs.

Remember, the best way to maintain good indoor air quality is to combine the use of an air purifier with regular cleaning and proper ventilation. Always consult with a healthcare provider or an air quality expert if you have specific health concerns related to air quality.
