Everyone who considers buying an air purifier always has one common question. Does an air purifier cool the room? You might have heard both yes and no as an answer. Well, the actual answer is both a yes and a no.

An air purifier is a fan that circulates back the unhealthy air in your surroundings after cleaning it with its filters’ help. The more the number of filters is in an air purifier, the less airflow towards you. Nonetheless, if you want to know the airflow of an air purifier, it is essential to know its CADR (Clean air delivery rate) rating. CADR is the clean flow of air that an air purifier provides.

An Air Purifier Is A Fan, Not An Air Conditioner

The air purifier does not cool a room; neither does it heat it. Air purifiers work the same as a fan. It circulates the clean air in the room. Unlike an air conditioner, air purifiers do not come with a cooling unit. You might feel a light breeze in the presence of an air purifier due to its fan. When the air purifier directs the airflow towards you, a light cool breeze can be felt. For a higher cooling effect, you should look for an air purifier with a higher CADR rating.

The Direction Of Airflow

The direction of airflow is an essential factor in deciding the hotness or coolness of the air. The order of airflow in air purifiers is manufactured to be in two standard ways nowadays:

  • Airflow in an upward direction.
  • Airflow in the forward direction.

Airflow In The Upward Direction: The air purifiers with air flowing out from the top are not effective in providing cooler air. Most leviot air purifiers and other cleaners have an upward direction of airflow. In this type of air purifier, there is no cooling effect. They are more suitable for winter or in places where the heat in summer is not a big problem.

Airflow In The Forward Direction: Most standing air purifiers have a forward direction of airflow. They are known to be more suitable for the summer season. They circulate the same clean air as the air purifiers that have upward airflow direction. The only difference is that the cooler breeze’s hint is towards you rather than flowing in the upward direction. This direct flow of air is the reason the air might feel cold.

Air Purifiers Without Filters And Fans

Filterless air cleaners and air purifiers without fans use no fans to purify the air. They work on ionic or electrostatic technology to clean the air. Some air purifiers use UV-C light to kill the pollutants. All such air purifiers do not have a fan or a filter. Therefore they do not provide any cooling.

Air Purifiers With Filters And Fans

The air purifiers that use filters purify the air with the help of a fan. These air purifiers are known to cool the air because they work as a fan. Fan air purifiers bring in the effect of a cool breeze by circulating the air at a higher delivery rate.

So What To Do To Make My Room Colder?

It is a basic understanding that air purifiers cannot cool a room. It is also understood that air purifiers are needed all the time whether or not they cool the room. However, some air purifiers act efficiently as air coolers and purifiers, such as Dyson Pure Cool air purifiers. Thus, the best alternative solution to this is to get an air purifier and cooler.

Portable Air Cooler

Most of the portable air coolers are convenient as batteries power them. They are easy to use and require no maintenance. Nonetheless, even though they are a cooling device, it is essential to remember that they are not as effective as an actual air conditioner.
