Does Air Purifier Cool the Room? A Complete Guide For You

Undoubtedly, an air purifier alone can do wonders but does an air purifier cool the room? This has been quite a query that was a part of the discussion, however, what is the truth about it, here is a guide.

Does air purifier cool the room?

Speaking of the cooling factor of an air purifier, the straightforward answer is No, an air purifier does not. The reason is its mechanism which is not part of an air purifier, however, it only circulates the air in the areas through its filters, not in the case of ionizers. This is how a unit works.

Air Purifier Working

The key purpose of an air purifier is to filter the air by capturing the pollutants from indoors which is done with the help of a built-in fan but with filters.

As said though the air purifier lacks the cooling mechanism but it does have a fan feature which does not mean that it is a substitute for a fan. Here is how it works.

1.    Fan of an air purifier

Here is the first logic. Air purifiers possess a fan that regulates the airflow in different directions. There are chances that you might feel cool when the direction is toward you due to the airflow. This sensation of cool airflow is determined by the air purifier’s CADR (clean air delivery rate), which usually varies between 80 to 300 CFM.

The desk fan and/or ceiling fan has a huge cubic feet per minute of more than 1000 which is higher than any air purifier.

2.    Direction of a unit

A ceiling fan comes with 2 modes summer and winter in which the direction of the air is changed. For instance, in summer, the airflow direction is downwards and clockwise for cooler air toward us. While in winter mode, the direction is upward and anti-clockwise to push hot air downward.

Similar to some extent to a ceiling fan, an air purifier uses an upward direction for circulating the air in the room. It draws the air from all directions (mostly in modern units). This may make your room even hotter because it pulls down the warm air from the ceiling. Such air purifiers are helpful in winter.

For the forward airflow, the tower-style air purifiers outflow the air by capturing the air from the back and throws in the front. These air purifiers are perfect for summer.

Hence, another reason that an air purifier does not cool the room.

Difference between a ceiling fan and an air purifier

The basic difference is their core purpose, one has to purify and filter the air while the other has to lower the temperature indoors.

A Ceiling Fan

  • Circulates the air in the room in upward and downward directions
  • It does not clean or filter the air
  • A ceiling is more likely to spread dust, pet hair, and other pollutants in the air

Whereas, an air purifier

  • An air purifier possesses filters that capture all types of pollutants to 99.97 percent with the HEPA filter
  • It does not cool or warm your room
  • The airflow is different, most of the latest designs capture air in 360-angle from all directions

A ceiling fan, however, can help the air purifier capture much pollution, however, it can also clog the filters of your air purifier because of the large airflow.

Can I have an air purifier and cooling fan in one device?

There are some brands that manufacture air purifiers with an additional cooling feature, a fan through which you can enjoy cool and healthy air altogether.

Circulating air can give a rise to air pollutants and other particles as well leading to allergies along with other respiratory problems. To get over it, you can consider an air purifier with a cool effect through which you can enjoy healthy and cool air simultaneously.

How to cool down a room when an air purifier is running?

An air purifier works ideally when the airflow is great so placing it near doors, windows, and hallways is the best solution but you have to be careful as there are chances of loss of purified air too. However, when it comes to cooling, an air purifier is more likely to warm your room than to cool it.

To cool your room, the first thing that you do is add an air conditioner. Other than that, you can minimize the heating in your room by

  • Using heavy and thick curtains to block the direct sunlight
  • Use insulation in your house or in the rooms
  • Add a heat-exchange ventilation system to your home
  • If you live in a humid area, add a dehumidifier to maintain the right amount of humidity
  • Add plants to have a cooler impact
  • Install ceiling fans or use other types of fans

Can a ceiling fan improve the air quality?

No. A ceiling fan does not have anything to do with the air quality of the room as it works for different purposes, and has different mechanisms and functionality. However, if the direction of your fan is placed in a way to bring more airflow, it can accompany the air purifier to capture more pollutants.

How can I improve the air quality indoors at IAQ?
