According to the report, 1.3 billion people in India, or 96% of the population, have air quality that is seven times greater than WHO limits.

Air pollution can cause many health problems. Our homes are likewise not safe from air pollution, especially in urban areas. Air purifiers and aroma diffusers are extremely popular these days, and many people use them to make their homes a more comfortable place to live.

While both an air purifier and an air diffuser can enhance the air quality in your house, they are not the same.

While an air purifier can remove dust by filtering the air, air diffusers are used to create pleasant smells in the home, which can benefit both your health and the air in your home.

In this article, we will look at the differences between air purifiers and aroma diffusers, as well as why and how they are used.

What is an air purifier and how do they work?

An air purifier filters out pollutants, allergies, and other hazardous airborne particles from air. The industry-standard True HEPA (High Efficiency Particulate Air) filter air purifier removes 99.97% of indoor air pollutants as small as 0.3 microns.

Air purifiers have layers of filters that remove microscopic particles from the air and circulate clean air in the space. Some air purifiers with ionizers generate a static charge around air particles, such as germs and viruses, so that they can fall onto the surface rather than moving in the air. This protects the air from spreading of certain viruses.

However, because they only allow particles to fall on the surface, you need to thoroughly clean the area to avoid resurfacing.

Benefits of Air Purifier

  • An air purifier can remove allergens from your home. Airborne allergens can cause symptoms like sneezing, congestion, a runny nose, and itchy or watery eyes.
  • An air purifier can save you from an asthma attack by managing pollution levels in your home.
  • Some air purifiers may trap germs and viruses, removing them from the air as it passes through the filter. HEPA filters have been shown to catch particles containing COVID-19.
  • An air purifier can help limit the spread of dust by eliminating particulate matter from the air before it settles.

What is an aroma diffuser and how does it work?

If you enjoy having a pleasant aroma in your room, a diffuser or an oil diffuser is an excellent choice. Aside from their pleasant and relaxing aromas, essential oils make several health benefits, such as promoting healthy sleep, relieving stress, and soothing headaches.

Diffusers break down and release the essential oils used in aromatherapy. This essential oil concentration in the air provides a soothing and relaxing effect. Different types of diffusers accomplish this process in different ways, which can be advantageous depending on your preferences.

Benefits of Aroma Diffuser

  • Aroma diffuser can help improve your mood and reduce stress with the right essential oil in it.
  • Essential oils help you get radiant and hydrated skin while also reducing wrinkles, uneven skin, acne, and loss of elasticity.
  • An aroma diffuser can help in creating a good sleep environment so that you can sleep better at night.
  • An aroma diffuser can also help with many health conditions such as digestive disorders and breathing problems; while there is no scientific proof, people who use them claim that it has some health benefits.

Difference Between Air Purifier and Aroma Diffuser?

Here is the short answer: Air purifiers purify the air, while aroma diffusers add a pleasant scent to it.

An air purifier works by purifying the air. This means it cleans the air, removing bacteria and other contaminants so you can breathe easier. It's ideal for people who are allergic to dust, pollen, pet dander, and other allergens.

Air purifiers typically use filters to purify the air—sucking it in, filtering out contaminants, and sanitizing it before recirculating it into the space.

Diffusers, on the other hand, are aromatherapy devices that  emit essential oils into the atmosphere.

Diffusers and humidifiers are sometimes confused since both add moisture to the air, but a diffuser's primary job is to make the air smell nicer with aromas from your preferred essential oil—humidifying the air is a byproduct.

If the latter is your goal, a diffuser may not produce the same results as a humidifier unless it is particularly designed to do so.

Is it okay to use an air purifier and an aroma diffuser at the same time?

If your air purifier has a function of removing scent from the air then you can not use an aroma diffuser at the same time as if we use both of them together, the purifier will neutralize the smell and your essential oil will get wasted.

However, if your air purifier only removes germs or allergies from the air, there's no reason you can't use an air diffuser alongside it.

If you have an odor-neutralizing air purifier, simply switch between the air diffuser and the purifier. You can use an air purifier at night to keep dust from building in the air, and an air diffuser during the day.


Air purifiers and essential oil diffusers work in very different ways, but when used together, they can have a powerful effect. Your living environment will be free of indoor pollution and toxins, as well as filled with perfumed smells for a zen atmosphere.

While certain air purifiers are excellent at removing odors, this typically pertains to more prominent and strong-smelling fragrances, such as pet or cooking odor. Most essential oil diffusers will function normally without the purifier's filter, however they may reduce the fragrances slightly depending on how long you leave your device on.
