That is why on this blog, we look at certain appliances and their most likely problems.
For instance, we looked at problems that your pure enrichment humidifier is likely to experience.
In yet another post, we looked at possible reasons for your dehumidifier blowing cold air, and the solutions.
In this short post, we look at why your air purifier smells bad; the different smells and what causes them.
Air purifier smells bad: 8 causes
When your air-purifying unit starts making these nasty smells, you need to dig deeper and find out whether it is possible to stop them:
1. Air purifier smells like burning
For any appliance that runs on electricity, the smell of burning can happen and it can be such a big cause for concern. However, this does not always mean that it is burning.
The possible causes of the burning smell could include burning itself. Thus, if you notice that your air purifier smells like burning, first, unplug it.
Do not panic!
The dust that stays on the unit during packaging can smell like burning. Also, the smell could actually be the newness burning off.
But just in case it is a real burning smell…
Once you unplug it, smell the plug. If the device smells like burning, check the fuse. Smell the power cord. It is possible for a cable to burn and fall apart inside the coating.
Though rarely, the air purifier could actually be burning. If it is coming from inside the unit, you need to open it up and check it.
If the wiring was of poor quality, actual burning is possible.
2. Air Purifier Smells like Fish
If you think that your air purifier unit smells like fish, your olfactory senses are not failing you. It is indeed smelling nasty.
The possible causes for the fishy smell are mold and mildew growing on the filters. Yeast and bacteria are also notorious for causing such a nasty smell.
The remedy is to open up the appliance and check the filters. If your air is too damp and you do not run a dehumidifier, mold can certainly grow on the filters.
Change the filters as often as possible, of course depending on your air pollution. In some places, you might need to change the filters once a week.
3. Air purifier ozone smell
If you have been asking: what does ozone smell like air purifier? It has a sharp and pungent smell, it is not exactly like ammonia or chlorine, but it is sharp.
If you experience such a smell, just know that your air purification unit is discharging ozone. But please note that not all types of air purifiers produce ozone.
Open the windows and doors so that the ozone can dissipate. But that is counterproductive because then, the air purity drops.
Thus, it is just better to shelf the ionizing unit and get a HEPA filter unit.
4. New air purifier smells Like Plastic
If you have a new unit, it is quite alright for it to smell like plastic. After all, the casing is mostly plastic, so if it is new, the device will have a plastic or chemical smell.
But that should dissipate with time. Depending on some things though, some may take longer to lose the smell.
Since the plastic odor is not harmful, we would say there is no need to worry about it.
5. Honeywell air purifier smells like wet dog
If your air purifier smells weird, say fishy or like a wet dog, there is yeast, fungi, bacteria or mold involved.
Thus, if you notice that your unit smells like a wet dog, it means the filters have mold. When you switch it on, it starts sucking air inside and blowing it out after passing it on the filters.
This is when you will experience a more pronounced wet dog smell.
When your air is too polluted and the humidity is high, grime and grease might form on the filters. This will cause a wet dog smell.
Many sources say that too much mold on the filters is the main culprit of the wet dog odor in your house.
So before you kick your canine friend out of the house on a hot summer day, smell the air purification unit to find out whether it is responsible for the odor.
6. Air purifier smells like dust
Since dust is one of the most common pollutants that you find almost anywhere, it is only logical to expect that some time; you will get a dusty smell from your unit.
Usually, this happens when the filters are too dirty and they are not doing their work correctly. If it has been some time since you last changed the filters, you will experience dusty air.
7. Vinegar odor from air-purifier
This is a weird odor from an air purifying unit, but some customers have reported it. Well, if you experience such a smell when the unit is new, you could be confusing the new chemical or plastic smell with vinegar.
In any case, it would be better to call the manufacturer or supplier because no unit is supposed to smell like vinegar.
8. Air Purifier Smells Like Smoke
If you notice the smell of smoke in the air coming from the purifier, there are possible causes.
One of them is that the air going inside has smoke and so the unit is not doing a very good job. Maybe the filters are not removing the smoke from the air.

Well, it could smell like cigarettes if it has been used in a house with one or more smokers.
Tobacco smoke has that habit of lingering behind on clothing and other surfaces. However, it should dissipate after some time.
