Air purifiers are designed to improve air quality, but they can sometimes emit unpleasant odours. A burning smell could indicate an electrical problem, such as faulty wiring, a clogged filter, or a burnt-out electrical component. In this case, it is recommended to unplug the purifier and consult a professional. Other causes of bad smells include poor-quality air filters, chemical contamination, clogged filters, and bacteria, mould, or yeast growth. To prevent odours, it is important to regularly clean or replace filters, ensure proper ventilation, and avoid operating in overly humid conditions.

What You'll Learn

Poor air purifier placement
- Avoid placing the air purifier near walls, corners, or behind/below furniture. Ensure it is at least 6 inches away from such obstacles, as this will hinder its ability to effectively clean the air in the room.
- Place the air purifier near the source of odors or pollutants. For example, in the kitchen, place it near the stove, and in the case of a smoking neighbor, place it near the vent or wall where the odor is most concentrated.
- Keep the air purifier away from heat sources and electronics. Some electronics, such as microwaves, stereos, and televisions, can be affected by the air purifier's operation and may cause interference.
- Avoid high-humidity areas, as moisture can damage the air purifier and affect the performance of its filters.
- Consider placing the air purifier on a raised surface, such as a dresser, to increase its floor-to-ceiling cleaning efficiency. However, ensure it is no higher than 5 feet off the ground.
- Ensure accessibility to power outlets. Place the purifier near a power source to avoid unsafe setups, such as having cords running across the room.
- For bedroom placement, it is recommended to position the air purifier 6-10 feet from the head of the bed, ensuring the air does not blow directly at your face.
- If you have pets, place the purifier close to where they spend most of their time, avoiding direct airflow towards them.
- Keep the windows and doors closed when using the air purifier. While it may seem counterintuitive, open windows and doors can allow outside particles to enter, reducing the purifier's effectiveness.

Electrical faults
If your air purifier smells like burning or electrical, it could indicate an electrical fault. This could be due to a short circuit or faulty wiring, which can lead to a burning smell. In such cases, you should immediately unplug the device and stop using it to prevent any potential fire hazards.
Another potential cause of electrical faults resulting in a burning smell is an overheated motor. This can be caused by clogged filters, which force the motor to work harder and overheat. Therefore, it is important to regularly clean or replace the filters, as per the manufacturer's instructions.
In some cases, the burning smell may be caused by a faulty UV light filter. The UV light may be damaged, causing a burning plastic smell. Regularly inspecting the air purifier and ensuring the UV light is functional can help identify this issue.
Additionally, the electrical fault may be due to the use of low-quality materials or poor manufacturing processes. This includes the use of volatile organic compounds (VOCs) in plastics or adhesives, which can emit a distinct and irritating smell.
If you suspect an electrical fault, it is recommended to seek professional help or consult an electrician for repairs. It is important to prioritize safety and not use the air purifier until the issue has been properly addressed.

Clogged filters
To prevent clogged filters, it is important to clean or replace them regularly. Some filters, such as carbon filters, can be rinsed with warm water every 3-4 months, while others, like HEPA filters, should not be washed with water and may need to be vacuumed monthly. It is important to avoid using detergents or soap when cleaning filters, as this can hamper their effectiveness. If the filter is not washable, it will need to be replaced.
If the filter is clean but the burning smell persists, it may be an issue with the motor or electrical components. In this case, it is recommended to unplug the air purifier and inspect it for any visible damage or signs of overheating, such as melted plastic or discoloured components. If the issue cannot be identified or resolved, it is best to seek professional help.
In addition to regular filter cleaning and replacement, proper placement of the air purifier is important to prevent clogged filters. The purifier should be placed in an area with good airflow and away from direct moisture sources to prevent moisture build-up, which can lead to mould or mildew growth and cause unpleasant odours.
It is also worth noting that some air purifiers use ionizers that produce ozone to clean the air, but high concentrations of ozone can be harmful to health and create an unpleasant smell. If your air purifier has ozone-producing parts, it is recommended to turn them off.

Faulty UV light filter
A burning plastic smell from your air purifier could be the result of a faulty UV light filter. The UV light in your air purifier can interact with Volatile Organic Compounds (VOCs) in your home, which are emitted from things like paint, furniture, and cleaning supplies. This interaction can sometimes create new, equally pungent byproducts.
UV light is also powerful enough to break down materials close to it, such as plastic, insulation, or ductwork. As these materials degrade, they can release unpleasant odors. A burning smell is a red flag that something is not right with the electrical components of your air purifier.
Faulty wiring, loose connections, or damaged wires can overheat and produce a burning odor. A failing ballast or power supply can also overheat and emit a burning smell before failing completely.
If you suspect that your UV light filter is faulty, it is important to contact a qualified technician or electrician to address the issue. Do not attempt to fix electrical issues yourself.

Poor-quality air filters
Another issue with poor-quality air filters is chemical contamination. During manufacturing or cleaning, the air purifier may come into contact with chemicals that release a plastic-like odour when heated. This can be mitigated by airing out the purifier and allowing fresh air to circulate through the unit.
Additionally, dust and debris accumulation on poor-quality filters over time can result in unpleasant odours. Regular cleaning and maintenance of the filters, as well as the exterior of the unit, are crucial to preventing this issue.
Poor-quality filters can also contribute to moisture build-up, creating an environment conducive to the growth of bacteria, mould, and yeast. This can result in a range of foul odours, including a ""wet dog" smell. To prevent this, it is essential to store the air purifier in a dry area and consider using filters with antibacterial and UV properties to inhibit the growth of microorganisms.
Finally, poor-quality air filters can lead to increased motor strain and overheating, potentially causing a burning smell. This issue may indicate a clogged filter, a malfunctioning motor, or a burnt-out electrical component. It is important to regularly inspect and replace poor-quality filters to prevent potential fire hazards and extend the lifespan of the air purifier.

Frequently asked questions
A burning smell could indicate a serious electrical problem, such as a short circuit, faulty wiring, or a clogged filter. Turn off the purifier and unplug it from the power source. Check for any visible damage, such as melted plastic or discolored components. If the burning smell continues, it may be an issue with the motor or electrical components.
The plastic smell is likely due to trapped plastic fumes or burning plastic inside the air purifier. Plastic molding produces strong fumes that are sometimes left trapped in the product during the initial process. When connected to an electricity socket, these fumes re-emerge. This smell should diminish with several uses, but if it doesn't, the purifier should be inspected.
The chlorine-like smell is likely due to ozone, which is a byproduct of some air purifiers. While it usually has a clean smell, similar to the scent after a thunderstorm, too much ozone can be harmful to your health.
An electrical smell could indicate an electrical fault. Take the purifier to an electrician for repairs.
