Can Air Purifiers Make You Sick? (Headaches & Sinus Problems)

by Josh M

You have been down with flu-like symptoms, and you have been wondering where you got the flu. Even worse, the symptoms get worse when you have your air purifier is running. So, your mind is always wondering: Is there a connection between the air purifier and your illness?

Can air purifiers make you sick? Read along; we have an answer for you.

Air purifiers remove contaminants from the air in a room. Air purifiers also remove dust, pollen, mold, smoke, and other airborne particles. Air purifiers can also effectively remove certain chemicals and gasses from the air.

Most air purifiers use filters to trap particles, while others use ionizers to charge particles so magnets can catch them.

Clean air free from contaminants is essential in our homes. Air purifiers perform this function for us, but they tend to negate this over time if not well maintained.

Can An Air Purifier Cause Sore Throat?

The answer is yes. While air purifiers clean the air around us, some air purifiers also emit ozone, a gas that can harm your health. Ozone is a powerful oxidizing agent that can irritate your lungs and eventually cause sore throat due to corrosion.

Do Air Purifiers Cause Sinus Problems?

There is no simple answer, as it depends on various factors. One possibility is that the air purifier is not sized correctly for the room. If it is too small, it will not be able to filter all of the room’s air, which can lead to sinus infections.

Another possibility is that the air purifier is not powerful enough to remove all particles from the air. Eventually, this leads to sinus problems.

Finally, it is also possible that the air purifier is causing dryness in the air, which can irritate the sinuses and lead to problems.

Can An Air Purifier Cause Headaches?

Some experts argue that air purifiers can aggravate headaches in certain people. The theory is that when air purifiers remove contaminants from the air, they can also reduce the level of oxygen in the room. This can lead to fatigue and, ultimately, headaches.

Can An Air Purifier Cause Dizziness?

If not adequately ventilated, an air purifier can cause a buildup of carbon dioxide that can make you dizzy.

Additionally, the air filter in the air purifier may be dirty. A dirty air filter can restrict airflow and cause the unit to work harder, resulting in higher noise and vibration levels. If you are experiencing dizziness from your air purifier, try cleaning the air filter.

Can Air Purifiers Cause Breathing Problems?

During the air purification process, air purifiers emit ozone, a gas that can be harmful to lung tissue. Ozone gas irritates the lungs and causes eventual shortness of breath.

In addition, some air purifiers generate negative ions, which can attach to dust and other particles in the air and make them easier to breathe in. Unfortunately, all these eventually lead to breathing problems.

Can An Air Purifier Cause Cough?

While air purifiers can effectively reduce the concentration of these contaminants, they can also cause some harmful side effects.

One of the most common is coughing. The draft created by an air purifier can irritate your throat and lungs.

Can An Air Purifier Cause Nose Bleed?

The use of an air purifier may cause nosebleeds in some people and exacerbate existing conditions. However, the air purifier most likely removes irritants from the air that could trigger a nosebleed.

Can Dirty Air Purifier Filters Make You Sick?

Cover air purifier filters prevent your family from breathing in harmful contaminants. But can they also make you sick? It’s possible.

If the filter becomes very dirty, it can release contaminants back into the air, negating the purpose of the purifier. In addition, if the filter is not changed regularly, it can become a breeding ground for mold, bacteria, and other microorganisms.

These microorganisms can then be released into the air, causing illness. Therefore, it is essential to regularly change your air purifier filter to avoid these problems. Most experts recommend changing the filter every three to six months. However, if you have pets or live in a particularly dusty environment, you may need to change it more frequently.

One should wear protective gear while changing the cover filter to avoid inhaling the contaminants in the filter. In addition, slight agitation of the filter will cause the dust to go air-bone which is dangerous if you breathe in.

How To Make Sure That Air Purifier Won’t Make You Sick?

Since air purifiers can make you sick over time, there are several things you should consider to prevent possible illness in the future.

What is the best kind of air purifier to use?

When choosing an air purifier, it is essential to consider the specific needs of your home. For example, if you suffer from allergies or asthma, you will want an air purifier specifically designed to remove allergens from the air.

On the other hand, if you are looking for a way to reduce dust and pet hair in your home, a standard HEPA filter will suffice.

Can an ionizer air purifier make you sick?

Can an ionizer make you sick? The simple answer is yes; they can. First, however, it is vital to understand how and why this happens. Ionizers work by releasing charged particles into the air.

These particles then attach themselves to dust, pollen, and other airborne pollutants, making them heavier and causing them to settle out of the air.

While this can help reduce the number of harmful particles in the air, it can also lead to problems if the ionizer is not maintained correctly.

If the unit is not cleaned regularly, the buildup of charged particles can create an electrostatic field that can attract more pollutants to the unit rather than trapping them.

How to properly use the air purifier?

Proper usage of an air purifier depends on the specific device being used. Nevertheless, if you want your air purifier to work correctly, there are some general tips.

First, it is vital to place the device in the correct location. Ideally, the device should be placed in an area with good airflow, away from obstructions such as furniture or curtains. Second, it is crucial to run the machine for the recommended time.

What are the correct settings of air purifiers?

The most crucial setting on an air purifier is the fan speed. The higher the fan speed, the more influential the device will be at removing particles from the air.

Another setting to consider is the filter life indicator. This feature will help to remind you when it is time to change the filter.

How long should you use an air purifier?

How long should you use an air purifier? The simple answer is: as long as necessary to clean the air in your home or office. However, there are a few factors to consider when deciding how long to run your air purifier. For example, the size of the unit will affect how quickly it can clean the air.

Additionally, the type of air purifier you choose will also play a role in determining how long you should run it. Some units are designed for continuous operation, while others need only be used for short periods.
