Essential oils are a great way of adding atmosphere and healing qualities to surrounding air in a room. And also there are many essential oils that have air purifying qualities.

Can I use essential oil in air purifier?

Yes. Provided that it is the right kind of air purifier. Air washers and Air revitalizers use water to clean air and provide their own essential oils to be used in the air cleaners.

Unfortunately for any other type of air purifier, there is no place to add essential oils.

Air washers and revitalizers are both hybrid multi-tech machines that combine the air purifier with a humidifier and a essential oil diffuser.

Of the two, the revitalizer is actually marketed as a air purifier, humidifier,  and a essential oil diffuser.

It has a unique bowl design that draws air into a chamber where the water is basically thrown around and against the inside of the bowl to clean the air.

The provided essential oil is added right into the water. The key word here is “provided”. Most essential oils wont work well as an additive to water.

When the air purification process is done, humid,  aromatic water exits the machine.

These machines are meant to be a jack of all trades type of appliance and as hybrid are probably not as good at doing any of its functions individually as they could be done by purchasing the right appliance for the purpose.

For instance, as an air purifier, they’re much more limited at reducing household contaminants and odors then say an air purifier that uses a HEPA and carbon filter design.

As a humidifier, they are also limited and only really claim to lightly humidify the room as the air is being released from the machine.

As a diffuser, they do a good job of spreading out an aromatic scent throughout the room. They get a B+.

Air washers on the other hand do a much better job at cleaning the air than an air revitalizer. And even better than there air purifying capacity, they are one of the best humidifiers that money can buy.
But as for a diffuser, they are pretty much an afterthought. You can add scents to the water just like a revitalizer but they have to be the scents that they provide.

Can I use essential oil in air purifierdiffuser and humidifier difference

The difference between a diffuser and a humidifier is that a diffuser desperses aromatic essential oils scents into the air. Whereas a humidifier disperses water mist to add moisture or humidity to the air.

Also there are many humidifiers that have a essential oil tray to add a few drops.
So essentially, the right humidifier is already a hybrid humidifier and diffuser.

Diffusers can be used anytime of the year where humidifiers are mostly only useful during the dry months of winter.

There are also some similarities between diffusers and humidifiers though,
both must be cleaned often in order to avoid the appearance of mold in the machine.
And both provided it’s the right kind of humidifier can disperse essential oils into the atmosphere.

But humidity can also facilitate dust mites and mold spores which is contrary to the reason you would want a essential oil diffuser.

Air revitalizer vs. Diffuser

A air revitalizer is a hybrid machine that combines and air purifier, a humidifier and diffuser in one.
A diffuser is specifically made to disperse essential oil scents into the air.

This may be a good solution if you need a humidifier running while you are diffusing essential oils,

But if your air is already humid enough,  you may not want to add a humidifier to the mix especially in the warmer months when the humidity is already high.

Diffuser and air purifier? Same time?

No. The reason is most air purifiers come with a carbon filter that is designed to adsorb odors.
Running an air purifier with a carbon filter and a essential oil diffuser at the same time will reduce the effectiveness of the diffuser.

Also, air purifiers most always have a HEPA filter installed. HEPA filters are very dense filters better woven together so as to not allow anything above .03 microns to filter through.

Though a HEPA filter it’s not likely to interfere with an aromatherapy diffuser,  being that the essential oils that go in the diffuser are oily, you may find that the HEPA filter in your air purifier will get extra grimy from filtering out oil from the air. And reduce the life of the filter.

Do diffusers clean the air?Do diffusers clean the air?

Yes they can. There are many essential oils that have air cleaning properties.
Eucalyptus oil for one is great for making breathing easier.

Essential oils are often placed in humidifiers to help the recipient be able to breathe better and get a good night sleep when they are feeling stuffy or have a cold.

Tea tree oil is another essential oil they can be used for many anti bacterial purposes including everything from taking the sting out of a mosquito bite to fighting airborne mold spores.

The reason it is possible for essential oils to help with air purification is because essential oils are plant based, and plants are one of the best way to naturally keep your air oxygenated and clean.

Plants are also a great way to add a little humidity to a dry room without going the distance of purchasing a humidifier. Believe it or not, just keeping your plants watered will actually humidify your air.


Adding essential oils to an air purifier is possible if you have the right type of air purifier. Either a Air Washer or an Air Revitalizer.

Because both of these air purifiers combine air purification with a humidifier, They also come with their own essential oil scents that you can add to the water.

But most air purifiers are not made to disperse essential oils and do not have any place to add them.

There are also many humidifiers though, that actually come with a tray to add essential oil drops and will act as a diffuser.

This is a good idea when you need a humidifier running, but a humidifier is not something you typically need to run all year long.

And though there are some air purification qualities that come with many essential oils, running an air purifier and a essential oil diffuser is not a good idea because most air purifiers reduce odors with activated carbon, which will also reduce the scent of the essential oils.

Kind of defeats the purpose.

Also anything or oily in the air while the air purifier is running he’s going to absorb into the HEPA filter and potentially reducing the live of the filter.
