Can Air Purifiers Make You Sick? Potential Disadvantages of Air Purifiers

    can air purifiers make you sick

    Air purifiers are becoming increasingly popular in many homes, particularly among those who suffer from allergies, asthma, or other respiratory conditions. These devices can effectively remove dust, pollen, smoke, and other airborne particles from your indoor air, improving its overall quality. Additionally, air purifiers can help reduce odors, neutralize harmful chemicals, and even kill bacteria and viruses. However, despite their numerous benefits, there are also some potential drawbacks. One question that often arises is: Can air purifiers make you sick?

    How Do Air Purifiers Work?

    Air purifiers work by drawing in air from a room, passing it through one or more filters to remove particulates, and then circulating the cleaned air back into the room. The specific way an air purifier works depends largely on the type of filter it uses.

    The most popular filter types are High Efficiency Particulate Air (HEPA) filters, activated carbon filters, and ionizers. It is well known that HEPA filters can eliminate 99.97% of particles as small as 0.3 microns. On the other hand, activated carbon filters are fantastic at getting rid of odors and dangerous gases. Ionizers use electricity to charge particles in the air, which are then attracted to a collection plate or other surfaces in the room.

    How Can Air Purifiers Make You Sick?

    While air purifiers are generally safe and beneficial, they can potentially make some individuals sick due to a few reasons:

    1. Filter Problems

    The effectiveness of an air purifier relies heavily on the condition and placement of its filter. If the filter is not properly installed or is still inside a plastic bag (which is sometimes the case upon purchase for preservation purposes), the air purifier may not effectively clean the air. This means that instead of filtering out pollutants, the device may simply circulate unfiltered air. 

    Over time, this could lead to an accumulation of airborne particles in your indoor environment, potentially triggering respiratory issues such as coughing, wheezing, or even an asthma attack.

    2. Type of Filter Used

    An air purifier’s safety can also be affected by the type of filter it uses. Ionizers and other types of air purifiers work by releasing charged ions into the air. These ions cling to airborne particles, causing them to become heavy enough to fall to the ground. 

    This process, however, can produce trace amounts of ozone, a gas that can cause respiratory problems, particularly in people who already have asthma or COPD. Exposure to ozone can cause chest discomfort, coughing, throat irritation, and shortness of breath in healthy people.

    3. Incorrectly Sized Air Purifier

    The size of the air purifier you use should correspond to the size of the room it’s placed in. If the air purifier is too small for the space, the air will not be effectively cleaned. This is because the device may not have the capacity to filter the volume of air in the space adequately, leading to persistent airborne pollutants. 

    Over time, these pollutants can accumulate and potentially cause or exacerbate health problems, particularly respiratory issues. Symptoms can range from minor irritations like sneezing and nasal congestion to more serious conditions like chronic cough or bronchitis.

    How to Prevent Getting Sick from Using Air Purifiers

    To ensure the benefits of using an air purifier outweigh any potential drawbacks, it’s important to use them correctly. Here are some steps you can take to minimize the risk of getting sick from an air purifier:

    1. Ensure the filter is properly installed and not wrapped in plastic

    When you purchase a new air purifier, it’s common for the filter to be wrapped in plastic to keep it clean and free from damage during shipping. However, if the filter isn’t unwrapped before use, the air purifier will simply circulate unfiltered air. Always check and ensure the filter is properly installed and free from any packaging before using the air purifier.

    2. Choose air purifiers with HEPA filters, which do not produce ozone

    The industry standard for air purification is High Efficiency Particulate Air (HEPA) filters. They are capable of trapping 99.97% of particles as small as 0.3 microns, including dust, pollen, and smoke, without producing harmful byproducts like ozone. By choosing an air purifier with a HEPA filter, you can effectively improve your indoor air quality without worrying about potential health risks associated with ozone exposure.

    3. Select an air purifier appropriately sized for your room

    The effectiveness of an air purifier largely depends on the size of the room it’s placed in. A small air purifier may not have the capacity to adequately filter the air in a large room, resulting in suboptimal air cleaning. When purchasing an air purifier, be sure to check its Clean Air Delivery Rate (CADR), which indicates how much filtered air the device can deliver. Choose a model with a CADR rating appropriate for the size of your room to ensure effective air purification.

    4. Regularly clean and replace filters according to the manufacturer’s instructions

    Filters in air purifiers can become clogged with particles over time, reducing the device’s efficiency. To keep your air purifier running smoothly, clean or replace the filters on a regular basis according to the manufacturer’s instructions. Neglecting this maintenance task can result in the accumulation of pollutants, which the air purifier will then circulate back into your indoor air.

    5. Avoid using ionizing or ozone-producing air purifiers, especially if you have respiratory conditions

    While ionizing air purifiers are effective at removing particles from the air, they also emit trace amounts of ozone. Ozone can cause respiratory problems, especially in people who already have asthma or COPD. If you have a respiratory condition, or want to minimize your risk of developing one, it’s best to avoid ionizing air purifiers and opt for a model that uses a HEPA filter instead.

    By following these steps, you can enjoy the benefits of cleaner, healthier indoor air while minimizing the risk of potential health issues associated with air purifiers.

    Weighing the Use of Air Purifiers

    The decision to use or not use an air purifier in your home or workspace is a personal one, largely dependent on your specific needs and circumstances. On the one hand, air purifiers can significantly improve indoor air quality by removing allergens, dust, smoke, and other pollutants, which is especially beneficial for people who suffer from allergies, asthma, or other respiratory problems. 

    On the other hand, improper use of air purifiers can potentially lead to health issues. Therefore, if you’re considering getting an air purifier, it’s crucial to do your research and choose a model that suits your needs. 

    In essence, air purifiers can be a valuable tool in maintaining a healthy indoor environment when used correctly. However, they should be part of a broader approach to air quality that includes good ventilation, regular cleaning, and reduction of indoor pollutants. If you are not sure whether an air purifier is right for you, talk to a healthcare provider or an indoor air quality expert before making a decision.

    Remember, the goal is to create an environment that supports your health and well-being, and the decision to use an air purifier should align with that objective.
