Do air purifier cool the room

Can you use an air purifier as an air conditioner?

No Air purifier does not cool a room except a hybrid fan. Air purifiers are designed to remove harmful particles and gasses from the air. Generally, an air purifier is a fan that circulates the air in a closed space through its mechanical, electrical, or hybrid air filters. The increasing air pollution requires everyone to have an air purifier at home to remain safe and healthy. A typical air purifier consists of at least 1 to 3 filters, and the more screens, it has, the less direct airflow you can feel overall. If you think an air purifier can directly replace your ceiling fan, you are wrong. The circulation process is known as wind chill. This is when moving air blows over your body, blowing away the heat your body is producing. The air purifier can neither be nor are a substitute for fans or air conditioners. An air purifier compulsorily has an inbuilt fan and circulates air alright so it seems as though it may also be cooling the surrounding air. A fan’s function is to cool down a room by circulating air. While an air purifier can’t directly change a room’s temperature, the process of moving air will make the room feel more relaxed. For example, think of it this way, you are sitting in a room without a fan versus sitting in a room with a fan. The temperature and all other conditions are the same. In both cases, The measured temperature is actually the same but you feel cooler in a room with the fan. The difference in temperature is minimal with a long fan. It’s more of the evaporation from the skin that is sped up.  An air purifier can’t directly change a room’s temperature (because it is actually a fan), but the process of moving air will make the room cooler.

Why Does Air Flow Direction Matter?

In winter mode, the ceiling fan rotates clockwise to pull the air from the ground and pushes the hot air from the ceiling, as we know the warm air rises towards the ceiling. Air purifiers that pull air in through the bottom or sides and exhaust purified air upward into a room tend to help keep rooms warmer during the winter. An air purifier will not keep a room cold, and unless it is operated at a high fan speed, it will not provide the amount of airflow required to provide even a cooling effect from air circulation. On the contrary, a fan rotating in the clockwise direction pushes the hot air from the ceiling towards us. The same idea is used in the summer and winter mode of the ceiling fans.

In the case of an air purifier, you can only have one of the two standard directions:

  • Airflow in the forward direction
  • Airflow in the upward direction.
  • If we look at things scientifically, when you sweat you feel cooler when there is a breeze because the breeze helps evaporate the water on your body and carry away the heat from your body faster. So if a purifier has a sufficient breeze it can make you feel cooler in this way.


Furthermore, if you understand how convection works, a breeze or wind helps hot air in your room to rise and can push hot air out of your room and cooler air takes its place. When you bring two objects of different temperatures together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object. Heat is energy on the move.

Although the two sides of an air filter might look the same, they are not. If you’d examine them with a magnifying glass, you’d find that one side is more porous than the other. This allows the filter to effectively trap airborne particles while also minimizing the slowdown of airflow through your system.

Without an external agent doing work, heat will always flow from a hotter to a cooler object. Two objects of different temperatures always interact. There are three different ways for heat to flow from one object to another. They are conduction convection and radiation.


Upward air flow:

These air purifiers draw the air from the front, back, sideways, or use 360-degree directions. You don’t feel any colder, and these airflow designs will make the room hotter by pulling down the warm air from the ceiling. It’s perfect for the summer season. we can see nevertheless, Most air purifiers use upward air delivery directions to circulate the air in a room. The function of a fan is to cool down a room by blowing or circulating air. An air purifier can’t directly change a room’s temperature (because it is actually a fan), but the process of moving air will make the room cooler.  Your air conditioner does not just blow air but it cools it down first and then blows it out into your room repeatedly to a point it can even make your room feel like a refrigerator. The route I would go to keep the air in my room clean while keeping my room cool at the same time is the separate portable air cooler route. It means that the device takes the input air from either side of the back of the machine, passes it through the filtration system, and pushes clean air from the top. The problem with such air purifiers is that they are not suitable for hot climates. As you know, warm air rises to the top, i.e., the ceiling of the room. Therefore, when the purified air is pushed to the top, it gets mixed with the warm air.

Some examples of air purifiers with upward airflow include:

  • Medify MA-40 air purifier
  • Coway AP-1512HH

Forward air flow:

Linear air intake and outflow design can be seen on tower-style air purifiers. These air purifiers draw air from the backside and deliver it towards the front. Some air purifier uses oscillating features like stand fans. It will gave you strong benefits in the summer season. Just like I described for fans, you just run your portable air cooler or portable home air con while your air purifier is running. So between the Dyson and Delonghi air purifiers, I mentioned here, go for the Delonghi as it has no ionizer and lastly I would avoid the LG air con. Some people can stand on ionizers but if you have anyone with respiratory problems in your home, you would rather stay away. Finally, the route I would go to keep the air in my room clean while keeping my room cool at the same time is the separate portable air cooler route. The warm air is pushed downwards to us. warm air is lighter and tends to rise up and cooler air being heavy wants to settle down. This temperature variation from

A convection current which we often refer to as airflow. Moreover, the fans direct the filtered air directly at you. So, you feel a chilled breeze on your body because the air is thrown at you at a fast speed. The higher the airflow, the more cooling effect it produces. Therefore, the forward airflow air purifiers are best for use during the summer season. So, an air purifier won’t lower the temperature of the room. Based on the airflow rate (CADR) and the directions, whether you will feel chilled or not.

Some examples of air purifiers with forwarding airflow include:

  • Medify MA-25 Air Purifier
  • Winnix 5500-2

Should I Run A Ceiling Fan With An Air Purifier?

The air purifier + ceiling fan combo is perfect, especially for the summer season. The ceiling fan will draw the air towards the air purifier and make the room cool at the same time. Meanwhile, the air purifier takes the air, purifies it, and directs a chill breeze of fresh air toward you.


Air Purifiers Do Not Have a Cooling Unit?

In addition to having a fan,  especially on a really hot day, to effectively keep your room cool you will need to have some kind of cooling unit. This is why air conditioners work.


What Can You Do Instead To Cool Down Your Room?

If you want to purify your air and keep your room cool at the same time, you will be glad to know that you can achieve this without having to install air con in addition to an air purifier.


Can the air purifier keep external heat out?

A good way to cool a room with no windows is to prevent external heat from entering. If your home is heated, shut the doors will reduce heat from coming in and cold air from escaping.
