Everybody likes to be a in a clean, nice-smelling environment. Whether you are at home, at the office, in a class or a store, you welcome a breath of refreshing and clean air.

Many people try to keep their space smelling nice by using air fresheners and fragrant wicks. While this is a nice way to introduce a good smell in any space, it doesn’t remove the sources of bad odors. For that you need an air purifier.

A regular air purifier traps the unwanted particles of pollen, dust or smoke from the air around you. It cannot however, do anything about the unwanted and odorous gases in the air. For that, you need an activated carbon air purifier, also called a charcoal air purifier.

The charcoal or carbon refers to the filtration medium used in these purifiers. Charcoal is a highly adsorbent material that is used to trap the volatile organic compounds (VOCs) from the air to keep the air clean and pollutant free.

Best Charcoal Air Purifiers Buyer’s Guide

When it comes to your living or working space, there are a few things you can compromise on, like appearance, organization and even lighting. But a bad smell is very hard to live with. This is the primary reason to choose a charcoal air purifier.

Why Choose an Air Purifier at All?

Before understanding a charcoal air purifier, it is important to decide whether you need an air purifier in the first place. The answer usually is: Yes.

Air purifiers are a great way to keep the air in your house or office clean and safe. It cannot substitute for the general cleanliness of the space, but it can enhance and improve upon it. Smokers and people with pets usually consider purifiers.

Smoking can instill a consistent smell in your living or working space. Pet dander and hair can be an unwelcoming surprise for your guests with allergies.

A good air purifier, better yet, a charcoal air purifier is the perfect solution for such problems.

Difference Between a Normal and a Charcoal Air Purifier

A normal air purifier, equipped with a HEPA filter is enough to clean the air. If there are only pollutants like dust particles, animal dander or hair and dust mites. But for odorous gases and unwanted organic carbons like germs and bacteria, a charcoal air purifier is needed.

A charcoal air purifier uses an additional filter called an activated carbon or activated charcoal filter. Once carbon or charcoal goes through the process of activation, millions of small pores are opened up in it. These pores let the activated material “adsorb” the unwanted gaseous particles.

Adsorption means that the particles stick to the filter, which keeps them from spreading around the room. Once activated, carbon and charcoal factors behave the same way. Though their activation processes are different.

This process makes a charcoal air purifier different from a normal air purifier.

When it comes to buying the right charcoal air purifier, there are some factors you should consider.



Area is an important consideration. You have to understand your need so you don’t make an expensive purchase that is too big for your small space. Either buy a purifier that is optimal for the space you have, or one that is flexible for a range of areas.

Choosing the right purifier per your required area will also prevent the filters from overworking. They will need to be replaced less often and reduce your maintenance cost.

Activated Charcoal Filter

It is impossible for a purifier to get rid of the unwanted odors and their source without an activated charcoal (or activated carbon) filter. This filtration element is also responsible for the removal of Volatile Organic Carbons (VOCs) from the air, making it cleaner.

HEPA Filter

A HEPA filter is also important for an overall air filtration. HEPA means High Efficiency Particulate Air. HEPA filtration is the mechanical filtration of the air. It has a mesh of minuscule proportions, usually with holes the size of 0.3 microns.

When air is passed through it, the mesh catches all the particles bigger than this size. This is usually enough to trap dust, pollen and pet dander particles.

Particle Sensor

A particle sensor is necessary for the automatic function of many charcoal purifiers. It decides how fast the fan should be. For manual control, this will let you know whether you want the fan to be slow, fast or turbo (for a high concentration of particles in the air).

Noise Control

Most purifiers run round the clock, especially at night to ensure clean air. Therefore, the noise output of the purifier should be considered. It is also important to understand that noise is different on different operating modes.

Filter Change Indicator

There are many factors that decide that your filter is used up. Like quality of air, daily operating hours and the kind of pollutants in the air. Since you can’t calculate all of them, it is important that there is a filter change indicator. It will let you know once the filter needs to be changed.

Additional Features

Apart from the above mentioned must-haves, a charcoal air purifier can have additional features as well.

  • UV-C light, for killing germs.
  • Ionizer for improved particle collection rate.
  • A time you can preset.
  • WiFi and app connectivity.
  • Auto and Sleep modes.

Features like these can make a charcoal air purifier better than its peers.


A charcoal air purifier is a good addition to a clean household or workspace. It purifies the air and makes it smell natural and clean without introducing any chemicals in it. This is important for the overall quality of living as well as your health.
