Why Your Air Purifier Smells like Ozone and How To Fix

Do you know why your air purifier smells like ozone?

Do you experience throat irritation, breathlessness or chest pains when the air purifier is or has been running? The cause of these symptoms is ozone being released into your indoor space.

The home appliances that we use daily produce certain smells that can alert you of a pending breakdown or an already serious problem with it.

The air purifier can develop many smells. For instance, it can smell like burning. It can also produce a plastic odor. In many cases, when the air indoors has been cleansed, the smells that you might experience are mostly the smells that have always been in the house.

But first …

When there has been a thunderstorm accompanied by lightning, there is usually a pungent smell. That is the smell of ozone. That is why it is also referred to as “after a thunderstorm smell.”

After a thunderstorm, the smell of ozone dissipates fast because there is more fresh air. However, if you have an appliance that is producing the O3 gas indoors, the smell of chlorine can linger for some time.

Many people also report their Honeywell air purifier has a weird smell. While these devices produce different kinds of smells, not all of them are bad.

It is best to try to identify the smell first so that you can know whether you need to take any action. The air purifier ozone smell is hard to miss because it has the same odor as chlorine.

When your unit is new, it is going to produce a plastic smell. There is nothing to be alarmed about because the plastic smell is actually the smell of newness.

Why does your air purifier smell like ozone?

It smells like ozone because it is ozone. Perhaps the question that you should ask here is: why does the unit produce ozone?

Mainly, there are two types of air purifiers. There are those that use HEPA filters and suction fans. These ones work by sucking in the air. The air then passes through the filters, which capture the pollutants.

The fans will whip the clean air out into your room, and that is how you enjoy fresh, clean air.

The second class is ionizer air purifiers. These ones use electricity to create negative ions, which they release into the air in your room.

The negative ions bond with the pollutants such as pollen, smoke molecules, formaldehyde, and other VOC (volatile organic compounds). They become too heavy and they fall to the ground.

The ion generating air purifier is the culprit for releasing ozone into your home. But it is not all bad. It has its benefits too. For instance, there are no filters to clean or change.

Why is ozone from air purifiers dangerous?

Ozone is capable of oxidizing the air in your home. It is also capable of oxidizing your lung tissue. It can also aggravate respiratory illnesses.

While ozone is not good for your health especially indoors, this does not mean that you should not use these types of air purifiers.

After all, they are very effective.

However, you need to know how to use the unit efficiently. That way, there will be no harm coming to the occupants of your home.

In addition to damaging the lungs, ozone can also give you chest pains, affect the throat tissue and it can cause breathlessness.

Air purifier makes room smell like ozone: How to fix

If you have an ozone generator instead of a unit that uses HEPA filters, there is nothing to fix. By this we mean that the ion generator will release ozone for its entire lifespan.

So then, does this mean you should change it?

Not really. However, you should take more deliberate measures to protect your family from the effects of ozone.

Here are a few things to help you:

First, Use the air-purifying unit when there is no one at home. That way, no one will inhale air with high concentration of ozone. Do not use it in a room with animals or indoor plants.

Secondly, after running the unit for some time, give the air enough time to dissipate the ozone. Unfortunately, you cannot open the windows because polluted air will come in from outside.

Thirdly, you need not run the ion generating air purifier longer than necessary. If you live in a place with very polluted air, you can run it for a few hours.

Just keep your windows and doors closed so that polluted air does not seep in from outside. Let the ozone dissipate fully, through the ventilation before coming back into the room.
