Foul odors: detection and elimination

Let us uncover the reasons behind air purifier odors for you and equip you with ways to keep your indoor air smelling as fresh as a spring breeze.

It’s time to clear the air about those perplexing smells emanating from your trusty device while ultimately an air purifier helps in sustaining pure fresh air in your home.

Plastic smell

This strong plastic smell can be both perplexing and concerning. Why does your air purifier smell like that? Don’t fret, we’re here to dissect the reasons behind this phenomenon and offer practical solutions.


#1. New air purifiers: when you first bring home a brand-new air purifier, it’s common for it to release a plastic smell. This odor arises from the materials used in manufacturing the unit and may linger for a short while as the device “breaks in.”

#2. Activated carbon filters: many air purifiers employ activated carbon filters to trap odors and volatile organic compounds (VOCs). However, these filters can emit a plastic-like scent when they are new or exposed to high humidity.

#3. Burning plastic smell: in some cases, when the air purifier smells like strong plastic, the smell may indicate an issue within the air purifier itself, for example, from a failing UV light filter. Overheating or malfunctioning components can lead to a burning plastic odor, a UV light filter being one of the most common ones.


Allow for ventilation: if your new air purifier emits a plastic odor, allow it to run in a well-ventilated space for a few days. This can help dissipate the initial bad smells.

Replace carbon air filters: if the smell is coming from the activated carbon filter (HEPA filter), consider replacing it with a fresh one. A carbon filter is effective at removing odors, but it can absorb them, leading to a scent buildup.

Check for malfunctions: if you suspect a burning plastic scent, immediately turn off the air purifier and unplug it. Check for any visible issues or overheating components. If necessary, contact the manufacturer for professional assistance.

While a plastic smell from your air cleaner may be disconcerting, it’s often a temporary issue with straightforward solutions.

By understanding the reasons behind the air purifier smell and taking appropriate steps, you can ensure that your air purifier not only improves your indoor air quality but does so without introducing any unwelcome awful smells into your living space.

Burning smell

Understanding the potential reasons behind this alarming odor and taking appropriate action can help resolve the issue safely.


#1. Overheating components: one of the most common reasons for a burning smell from an air purifier is overheating components. This bad smell can occur due to various factors, like dust buildup.

#2. Worn out or damaged parts: aging or damaged parts within the air purifier, such as wiring or electrical components, can generate a burning odor.

#3. Foreign objects: foreign objects or particles may find their way into the air purifier, coming into contact with the internal components.


Immediate shutdown: if you detect a burning smell, it’s crucial to turn off and unplug the air purifier immediately.

Inspection: carefully inspect the air purifier for visible signs of damage, foreign objects, or overheating components.

Regular cleaning: to prevent future burning smells, perform regular cleaning and maintenance of your air purifier. This includes cleaning filters, removing dust and debris, and ensuring proper ventilation around the unit.

While the burning smell may be due to a range of factors, addressing the issue promptly and appropriately is essential for safety and continued effective operation.

Ozone smell

Ozone, a molecule composed of three oxygen atoms, is known for its distinct and somewhat sharp smell. Why can an air purifier smell like ozone?

While some air purifiers produce ozone as part of their air-cleaning process, others are not.

If you detect an ozone odor from your air purifier and don’t expect it, it’s essential to understand the reasons behind it and how to address this situation.


#1. Ozone-producing air purifiers: certain air purifiers, known as ozone generators or ozone-producing air purifiers, intentionally release ozone into the air as a means of neutralizing odors and airborne contaminants. This is a deliberate design feature of these specific models.

#2. Unintentional ozone emission: in some cases, an air purifier not designed to produce ozone may emit trace amounts of it as a byproduct of its operation, particularly if the device includes ionization or plasma-based technologies.


Check your air purifier model: first and foremost, determine if your air purifier releases ozone. Consult the user manual or product specifications to confirm its ozone-producing capabilities.

Adjust settings: if you own an ozone-generating air purifier and the ozone odor is too strong or undesirable, consider adjusting the settings to a lower level or disabling the ozone-producing feature if possible.

Ventilation: ensure proper ventilation in the room where the air purifier is operating.

Adequate airflow can help disperse any ozone and reduce its concentration in the air.

Understanding whether your air purifier is designed to produce ozone and taking appropriate measures to adjust settings or consider alternative models is crucial to ensure that the air you breathe remains clean and odor-free according to your preferences.

Wet dog smell

Few odors are as distinctive and unpleasant as the musty wet dog smell. If you’ve ever detected this air purifier smell in your home, and your furry friend isn’t to blame, your air purifier might be a surprising source. Why does your air purifier smell bad?


#1. Moisture accumulation: air purifiers that use a water-based filtration system can sometimes accumulate moisture in the device. This moisture, when left unchecked, can create a damp environment conducive to mold and mildew growth resulting in an air purifier smell being like that of a wet dog.

#2. Dirty air filter: filters in air purifiers can become clogged with particles and contaminants over time. This accumulation in an air filter can lead to the development of air purifier smells, including those resembling a wet dog scent. An awful smell, indeed.


Clean and maintain water-based systems: if your device uses a water-based filtration system, be diligent about cleaning and maintaining it to prevent awful smells

Change or clean air filters: for air purifiers with standard filters (e.g., HEPA filters), replace or clean the filters in the air purifier regularly to avoid a bad smell.

Monitor humidity levels: keep an eye on the humidity levels in your home. If they are consistently high, consider using a dehumidifier to reduce moisture.

Ventilation: ensure proper ventilation in the room where the air purifier is placed. Adequate airflow can help disperse odors and maintain a fresh-smelling environment.

You can eliminate this undesirable odor and continue to enjoy the benefits of cleaner, fresher indoor air.
