Does air conditioner purify air?

Air pollution circulates in rooms that are closed during heating and cooling. Therefore, it is necessary to purify the air while cooling and heating with an air conditioner.

Does air conditioner purify air?

This is a common question for people who are thinking of buying an air conditioner.

The answer is yes and no because air conditioner does not purify air, but it can remove some of the pollutants.

What does air conditioner purify?

An air conditioner removes contaminants from the air.

  • AC removes dust, smoke, pollen, bacteria, viruses, mold, mildew, fungi, germs, and other airborne particles from the air we breathe. It does this by using a filter to separate the particles from the air.
  • AC also removes irritants. These include cigarette smoke, dust particles, pollen, chemicals, and other foreign particles. An air conditioner will remove them by either absorbing them into a water-based solution or by releasing them back into the room and filtering them again.

It is also important to note that AC is not only used in homes but also in hospitals, hotels, and other public spaces.

How do air conditioners purify the air?

Air conditioning uses an array of filters which not only keep out dust, pollen, bacteria and other pollutants, but also remove traces of oils from the air.

While keeping out all the impurities, air conditioning also keeps the room breathable and opens it to fresh air. It also keeps the room cool as it draws cool air into the room.

Air conditioners are equipped with a Humidifier to absorb moisture from the room from the humidity of the surrounding.

Similarly, air conditioning is known to enhance the air quality and make it more allergy free. And it is all possible with the help of the best air conditioners available on the market. Buy a Cooler to save on your energy bills.

The necessity of air purification

So, why do some air conditioners purify air?

  1. Some purify air to reduce the relative humidity. When the relative humidity is less than 30%, condensation can occur, and it will eventually be released as waste heat.
  2. When the relative humidity is high, condensation is prevented, which is obviously better for the environment.

A major benefit of air conditioning is the fact that it can lower the humidity in rooms, therefore lowering the overall humidity.


The negative effects of humidity are numerous:

For instance, because humidity is the culprit in the formation of mold, it can also lead to the breakdown of paints, furniture, and walls. This is because condensation is the main source of carbon dioxide, which can lead to irritation of the airways and lungs.


Air conditioning units clean the air in your home. Hence, you will be able to remove the pollen and other pollutants, which might be causing allergies and might be irritating your skin.

In addition, they also help in reducing the exposure of allergens to family members. Air conditioning units also heat the water that will help in cooling the room.

Therefore, in order to ensure a comfortable and healthy environment, you can have your air conditioner adjusted and maintained.
