Will My Air Purifier Keep The Room Cool?

As winter draws to a close, it’s time to begin thinking about how to keep your home cool during the warmer months. For some families, central air is the best option, while other may rely on window ACs, fans, or even open windows.

But, what about an air purifier? You already know how helpful an air purifier is in keeping dangerous pollutants out of your home… can it also help with cooling?

Do Air Purifiers Cool The Room? 

There are a lot of rumors about what air purifiers can and can’t do in your home.  One of the most common rumors is that air purifiers can cool your home. But, can they really? 

The simplest answer is no. An air purifier does not have any cooling components and therefore doesn’t have the capacity to change the temperature of the room. But! The true answer is a little more complicated….

An air purifier works by sucking in air with a fan, blowing it through internal filters, and then releasing clean air on the other side. While the filters are great at removing particles, they also slow down the air while it’s being pushed through, which hampers the purifier’s ability to cool the air.

But, even though the temperature isn’t actually reduced by the purification process, air purifiers do cause the air to move. When compared to the typically stagnant air inside our homes and offices, the airflow caused by a purifier will be faster, evaporate sweat easier, and feel cooler on your skin.

You can think of it like blowing on your food. The rush of air from your mouth cools food down faster than the still air in your home. 

Air purifiers with high airflow (also known as CADR) work best to make your air feel cooler, as they circulate the air faster than other purifiers. 

Air Direction Matters

The direction that the air flows makes a big difference in how cool the room will feel. Air purifiers use either upward or forward airflow direction

Upward airflow direction

Most purifiers use upward airflow direction, meaning air is drawn in from the front, back, sideways, or even all sides. These purifiers may actually make the room feel hotter because they pull down warm air from the ceiling. 

Forward airflow direction

Tower style purifiers typically rely on forward airflow direction, meaning they draw air from the backside and deliver towards the front. These are the purifiers that are most likely to make your room feel cooler.

Is An Air Purifier A Fan? 

Technically, air purifiers do move the air around in a room, which is one function of a fan. But, they aren’t able to produce the high-speed airflow that more traditional fans use to quickly circulate air and cool the room.

While air purifiers don’t serve the same purpose as a fan does, they still come with many benefits. Air purifiers can even help people with anxiety.

So, if an air purifier alone isn’t enough to keep your home cool, what can you do to lower the temperature inside, while still reaping the benefits of an air purifier?

How To Cool Down A Room While Running An Air Purifier

Since air purifiers work best when there is not much ventilation, running an air purifier while trying to cool the air by opening windows is not ideal. That’s because your air purifier has to keep up with the constantly incoming outdoor air. 

While an air conditioner is the obvious choice for cooling your home, it may not always be an affordable option. Here are some other ways to keep your indoor air cool while using an air purifier:

  • Make sure your home is well-insulated to keep cool air inside
  • Use thick, dark curtains to block sunlight
  • Maintain a comfortable humidity. High humidity will make you feel hotter.
  • Place cool water or ice in front of a fan so cooler air will be circulated.

Why Do I Need An Air Purifier?

Despite its lack of cooling power, an air purifier is an essential device for every home. No matter how clean your think your home is, every indoor space contains pollutants like pollen, dust, pet dander, gases and PM2.5 (fine particulate matter). These air pollutants can cause an array of health issues inclluding cognitive issues, allergy symptoms, and even premature death. 

When researching purifiers, look for ones that use a combination of both True HEPA  and activated carbon filters. The aair 3-in-1 Pro is an excellent option because it is able to filter out 99.95% of ultra-fine particles and lasts an average of 12 months for each filter.

So, while the answer to the question ‘do air purifiers make the room cold’ is no, air purifiers are still an extremely beneficial device for your home.

How Tax is calculated

The amount of tax charged on your order depends on many factors including the following:


  • The identity of the seller
  • The type of item or service purchased
  • The time and location of fulfillment


The shipment or delivery address of your order
These factors can change between the time you place an order and when your shipment is complete. As a result, the tax calculated on your order may change. We display an “Estimated Tax” to be collected at Check Out when confirming an order. The amounts displayed as estimated tax may then be updated later when your order is finalized and completed.


The tax rate applied to your order will be the combined state and local rates of the address where your order is delivered to or fulfilled from. For example, if you live in a state that does not impose a sales tax, you may still see tax calculated on your order if shipped to another state. Moreover, the tax rates applied to your order may also be different for a variety of reasons, such as a shipment to a residential home versus a business address. Also, the total selling price of an item will generally include item-level shipping and handling charges, item level discounts, and gift wrapping charges. If applied at an order level, these charges, may be allocated to the individual items in an order.


If you are ordering from aeris and shipping to a country outside of the US, you may be charged the applicable country tax rate.
