How To Fix An Air Purifier That Is Emitting A Burning Smell

When you acquire an air purifier, you expect it to improve the air in your environment. It's beneficial for those with respiratory issues. It can therefore be frustrating when it starts producing a burning smell. 

But, instead of worrying too much, it's best to know what is causing this so that you can solve the problem. Some of these problems are:

Faulty Wiring

If the wires are broken, or the coating has come off, it may give off a smoke-like smell. Stripped wires rub against each other, causing them to heat up and produce a burning smell. An electrical fault may also occur if something is blocking the fan's rotation in your gadget.

To find out if the wires are faulty, open up the appliance and inspect the wires. Replace all those that are damaged. Also, during your routine cleaning, always inspect the wires to ensure they are in good condition.

System Overheating

Without adequate ventilation, the air purifier may not cool off. This can lead to the electrical parts in your gadget overheating and producing a burning smell. Before taking it to a technician, try improving the ventilation in your home and see if the smell will disappear. 

Faulty UV Light 

If the UV light in your appliance is damaged, a burning smell will be emitted each time you turn it on. During cleaning, ensure the light is still in good condition. 

Saturated Carbon Filter

You can find this HEPA filter combo pack on Amazon.

The carbon filter is responsible for removing gasses. But, if these gasses accumulate on the filter, it will start to emit these gases, which smell like something is burning.  

To clear the smell, clean every 3-4 months by rinsing under water that's running gently. Vacuuming it once a month and replacing it once a year is recommended. 

Off-Gassing Plastic

If your appliance has a plastic covering, and it happens to overheat, the plastic can produce a burning smell. If burning plastic smells persists, your appliance may have faulty wires or a short circuit. Call a technician to check it.

Sweet Smell

Plastic Smell

If you have recently purchased your air purifier, there is a high chance that it will smell like plastic, like a new car. When you start using it, the parts inside warm up and release a plastic smell. However, don't confuse warming up with overheating. The former will produce the smell of plastic, while the latter will produce a burning smell. 

Your appliance will produce this smell for only a few days and eventually disappear. But, if it persists, you may have to contact your dealer to check what could be wrong.

Musty Smell

A musty smell from your appliance means it has gathered a lot of dust. The air filters are responsible for blocking out dust, debris, and foreign particles. If they are not cleaned as per their schedule, the air purifier may start releasing these particles producing a dusty smell. 

Smell Of Chlorine

Air purifiers that use ions and ozone to clean the air produce a chlorinated smell. Ionization is a technology that emits ions, which render contaminants in the air harmless. They remove mold, bacteria, odors, and more. Ozone is a strong oxidant that eliminates pollutants from the air.  

Wet Dog

Air purifiers can clean the air in humid areas. But, if the humidity levels are extremely high, your gadget may release a smell like that of a wet dog. If you live in such an area, you may have to buy pellets that absorb humidity. 

Sour Smell

Some air purifiers are designed to remove formaldehyde from the air. Due to this, your appliance may produce a sour smell. 

How To Maintain An Air Purifier

An air purifier is a gadget that helps improves the quality of the air you breathe. But, for it to work efficiently, your input is required by doing the following:

Ensure Your Area Is Clean
