Can You Put Essential Oils In An Air Purifier?

by Josh M

For those looking to reap the benefits of clean air in their homes, it is common to wonder if you can keep your home smelling fresh while using an air purifier at the same time. In other words, can you put essential oils in an air purifier? We decide whether you can kill two birds with one stone.

Air purifiers are handy machines that suck in air, filter out contaminants, and release the newly cleaned air back into the room. These products can be used at home or in the office to help you avoid air pollution in your daily life.

There are a few common types of air purifiers, including HEPA, activated carbon, UV, ozone, water, and ionic. Each of these comes with pros and cons when it comes to air filtration that needs to be carefully considered before purchase.

Essential oil fans love their fresh scent and environmentally friendly properties. For some, having a lovely smelling home without candles or stick diffusers is important; they begin to wonder if you can put these handy oils into air purifiers for maximum convenience.

Can you use essential oils in an air purifier? For the most part, no. Most air purifiers are not designed to be used with these oils. Some modern models have compartments or sponges that can hold and disperse these oils, but this is not common.

Some hybrid products that can diffuse or humidify and purify the air may have an essential oils feature, but they may not be as effective.

Type Of Air Purifiers That Can Be Used With Essential Oils

Of the air purifier model types, many people suggest that the water-bowl style ones work best with essential oils. These use a swirling bowl of water to pull pollutants from the air throughout the day; some suggest adding a few drops to the water itself to achieve your desired effect.

However, we would highly recommend against adding essential oils to any air purifier that is not explicitly designed with oils in mind. If you are not careful, an air purifier using essential oils without being designed with this in mind could become damaged or corroded.

Additionally, do not add essential oils to the air purifier filter – at best, this could stop the filter from being as effective due to the oil coating valuable filtration areas or could damage the air purifier at worst.

If you want some air purifier fragrance, we recommend finding a model with fragrances built into its design or purchasing a diffuser instead. This allows you to get that fresh essential oil smell without damaging your air purifier and potentially causing a health hazard. It would be best to avoid using both a diffuser and an air purifier at the same time as the oil particles may be filtered out of the air by the air purifier filter.

What Essential Oils Are Best To Use With An Air Purifier?

Once you have found a filter that can also disperse essential oils into the air, you will need to be careful about which oils you decide to use. Avoid sticky, sappier oils like cedar and myrrh as these can clog up the machine and cause a mess. Some of the best oils to use in diffusers include:

  • Lemongrass
  • Lemon
  • Orange
  • Peppermint
  • Lavender

It is best to try using a few drops at first and gradually increasing the dose each day to see what works best. This is because an aroma’s strength can be dictated by how pungent the oil itself is as well as the size of the room the air purifier is in.

Can You Put Essential Oils Directly On The Air Filter?

We do not recommend putting any essential oils directly on the air filter itself. At best, this can clog the filter, which will cause it to be less effective at air filtration. At worst, it can corrode or damage the internal parts of your air purifier, causing a health hazard and unnecessary money-wasting to buy a replacement.

Because of this, it is best to avoid using essential oils on air filters when trying to freshen up your home. Read over your product’s instruction manual carefully to find the specialized essential oil compartment or sponge alongside any tips and tricks.

Common Air Purifier and Essential Oil Questions

How long do essential oils last in the air?

How long essential oils linger in the air depends on a variety of factors, including the size of the room, how many drops of oil were used, and how long the machine has been running. Try topping up the sponge over the course of the day or adding more drops initially to see what works best for your home.

What’s the difference between a diffuser and an air purifier?

Diffusers disperse scented water particles into the air, whereas air purifiers capture pollutants and allergens in the air and filter them out before pushing out clean air. Oil diffusers are primarily used to get fresh scents, whereas air purifiers can be good for your health.

What is Essential Oil


Part of knowing how to use essential oils in air purifiers is choosing the right air purifier model for your needs. If you are an essential oil fan, try to find a model that has a specified oil diffusion function or try a diffuser out for size. Always check your manual and exercise caution when considering using these oils.
