Side Effects of Air Purifiers: Common Risks and Health Concerns

Do you know about the potential negative side effects of air purifiers? Unfortunately, many modern air purifiers may do more harm than good, making them less effective in reducing air pollutants and allergens.

Quick Summary

  negative Side Effects of Air Purifiers: Common Risks and Health Concerns

Air purifiers, also known as air cleaners, are becoming an increasingly popular way to filter the air, remove pollutants, and improve air quality in homes and other spaces. While air purifiers can be beneficial for reducing allergens, particles, and other pollutants, there are certain risks and health concerns associated with their use.

The most common side effect of air purifiers is that they can cause a type of irritation or respiratory irritation in people who have asthma or allergies. People who are sensitive to airborne particles may experience shortness of breath, coughing, sneezing, or irritated eyes after spending time in a room with an air purifier. In some cases, people with allergies may experience an increase in their symptoms if the air purifier doesn’t contain the right filter and traps too many pollutants.

Ozone air purifiers may also contribute to health concerns. While ozone is powerful in cleaning air, it can also be dangerous when inhaled in high levels. Ozone is known to irritate the respiratory system, including the nose, throat, and lungs, and can negatively affect those with asthma and other respiratory diseases. Additionally, ozone air purifiers should not be used in unventilated rooms, as the high ozone levels can be harmful.

In conclusion, air purifiers can be beneficial for improving air quality, reducing allergens, and other pollutants. However, it is important to be aware of the potential risks and side effects associated with air purifiers, especially ozone air purifiers, to minimize health concerns.

Negative Side Effects of Air Purifiers: Common Risks and Health Concerns

Air purifiers are becoming increasingly popular due to their ability to reduce irritants and pollutants in the air. While they are generally beneficial, there can be a few negative side effects to be aware of. Here are some of the more common risks and health concerns associated with air purification.


When a new air purifier is used, it may emit what is known as off-gassing. This is a chemical reaction that occurs when volatile organic compounds are released from the air purifier’s components. These compounds can include acetone, formaldehyde, and other hazardous chemicals. While the off-gassing risk is minimal, those with pre-existing respiratory issues may suffer from increased difficulty breathing and other health concerns.

Ozone Emissions

Ozone is a gas that can provide a variety of benefits when used correctly. Unfortunately, when ozone is emitted from air purifiers, it can cause a number of health issues such as eye irritation, lung irritation, and other respiratory irritation. To ensure safe use of your air purifier, be sure to check the manufacturer’s instructions and emissions rating.

Compromised Indoor Air Quality

While air purifiers can often improve indoor air quality, the wrong type of filter or replacement filters can actually cause the opposite to happen and cause your indoor air quality to worsen. To ensure that your air purifier is not causing any harm, be sure to buy the right type of filter and replace it when needed.

Allergen Build-up

Many air purifiers rely on filters to capture contaminants, but if the filters are not replaced regularly, the contaminants can begin to build up on the filter’s surface. This build-up can then be circulated back into the air, releasing the same allergenic particles that the air purifier was trying to remove. To protect against this, regular filter replacements are necessary.

Dry Sinuses

Air purifiers can remove moisture from the air, leading to dry sinuses which can cause irritation and discomfort. To combat this effect, use a humidifier in conjunction with the air purifier to maintain a comfortable humidity level.


If you opt for a more powerful air purifier, the motor and other components can create a significant amount of noise. This noise can be bothersome if you are in the same room as the air purifier, so make sure to test out any potential air purifiers before purchasing.


Air purifiers can be extremely beneficial, but it’s important to be aware of the common risks and health concerns associated with their use. By being mindful of these potential negative side effects and taking the proper precautions, you can ensure that your air purifier is providing you with the best air quality possible.

Personal Experience

Can air purifiers have a negative effect?

Having worked in air purification technology for many years, I have seen firsthand the potential negative side effects resulting from using air purifiers in certain situations. For example, air purifiers can produce ozone as a byproduct, which has been linked to an increased risk of respiratory problems. In fact, prolonged exposure to ozone can lead to permanent damage of the lungs and is especially dangerous for young children and the elderly.

Furthermore, poorly manufactured air purifiers can be loud and disruptive, making it difficult to focus and sleep even when running at the lowest fan settings. Additionally, high-powered air purifiers consume a large amounts of electricity, and this can be a costly strain on your energy bills. In general, these purifiers are also expensive and require regular maintenance and filter replacement.

Lastly, air purifiers that filter air by producing ions and/or ozone may reduce the efficiency of certain electronics; this is because the release of ions affects the charge that can build up on the exposed surface. In addition, the use of chemically treated filters can also release volatile organic compounds (VOCs) into the air, which can cause headaches and other respiratory ailments.

In conclusion, while air purifiers of all types can help to create a cleaner and healthier environment by removing harmful particulates, they also have a number of potentially negative side effects. Therefore, it is important to take into account the particular type of air purifier and its potential effect on your health when selecting the right unit for your home.
