DO AIR PURIFIERS
COOL DOWN A ROOM?

Normally, they don't. By default, it's a device to clean the air and not make rooms colder. However, some purifiers might help to lower down the overall temperature in the premise — read this article to get to know how.

Why Do Air Purifiers Not Cool the Room?

The answer to the question "Does an air purifier cool a room?" is negative in most cases. Typically, this device lacks air cooling mechanisms. According to their principle of operation, they fall into two categories.

  1. Air purifiers with fans circulate the air in a closed space through their mechanical, electrical or hybrid air filters. Unlike air conditioners, they don't cool the air before blowing it through the premise.
  2. Air purifiers without fans act like ionizers. They neutralize dangerous air particles.
You would hardly come across a device that has filters but lacks a fan and vice versa. A filter-less model does not blow out cold air. It does not influence the temperature inside the room.

If air purifiers work as a fan, we can classify them according to airflow directions. Tower-style devices feature linear air intake and outflow design. They draw air from the backside and deliver towards the front. Even though that's not cool air, purifiers with the forward airflow direction are optimal for summer because they don't make the room hotter. Plus, some of them use oscillating features like stand fans.

Models with the upward airflow direction draw the air from the front, back, sideways or use 360-degree directions. In this case, the answer to the question "Will an air purifier help cool a room?" is also negative. Moreover, in winter, such a device might make the room hotter because it will be pulling down the warm air from the ceiling (this process is called convection). The smaller the room, the easier it is to warm it up. If you install a purifier with an upward airflow direction in a large hall, it won't raise the temperature of the air too drastically.

A typical electric fan doesn't purify the air. Consequently, it can circulate larger amounts of air. Unlike fans, purifiers are equipped with filters. The more filters they have, the slower the air circulates and the less impact you feel. First, the fan sucks in the air in the system. Then, the air moves along as the filters do the rest of the cleaning work. The fresh air is then allowed to pass, as the fan pushes it out, creating some kind of breeze. If someone says that air purifiers cool down a room, they're probably talking about the power of the breeze. It might help you to cool down because it evaporates the water on your body and carries away the heat faster. But to feel the air moving over your skin you might need to sit next to the device. If you make just a few steps away, you would hardly feel any impact.

To estimate the strength of an air purifier, check its CADR (Clean Air Delivery Rate) rating, measured in cubic feet per minute. A typical purifier delivers from 80 to 300 CFM. An average desk or ceiling fan delivers over 1000 CFM, that's why the chill feeling from it is significantly higher.

Some people ask whether it is possible to install an air purifier and a fan in the same room and use them simultaneously. Yes, you can do it. Compared to an HVAC system, this might be a more cost-efficient solution. If you resort to it, it might be wise to turn off the fan when you sleep to avoid getting a sore throat.

Air Purifiers that Cool the Room

Sometimes, you might come across air purifiers that make the room cold. They are known as combo air purifier coolers. Their fans are strong enough to cool an entire room. Dyson Pure Cool or the Delonghi Air Purifier, Heater And Cooling Fan HFX85W20C can serve as worthy examples of this type. Alternatively, you might consider LG S-Q12BTXD Split Air Conditioner 1.0T. It is equipped with both an air filter that traps contaminants and an ionizer that neutralizes harmful particles.

Germ Guardian Air Purifier and Honeywell AirGenius 6 Air Purifier receive positive reviews from experts and customers too. Levoit Core 300 is a worthy option with a 360-degree air inlet and upward air outlet. Medify MA 40 takes the air in from the back and lets it out in the upward direction. If you prefer a front-back air inlet and upward air outlet, consider Coway AirMega 300.

One of the best solutions is Puroxygen. You can buy it on Amazon. It removes 99.98% of airborne contaminants and unpleasant odors. In addition to a standard HEPA filter, it has a pre-filter and an activated carbon filtration system that maximize its efficiency. Thanks to its UV light sanitizer and negative ion generator, it kills germs and bacteria, which is especially important for people with allergies, asthma or a compromised immune system.

Please mind that devices that may cool a room have three significant drawbacks.

  1. They require high maintenance. Taking care of them is almost just as difficult as replacing a filter in the air conditioner — most likely, you'll need professional help.
  2. Ionic air purifiers produce a harmful byproduct called ozone that might cause or worsen respiratory diseases.
  3. Their efficiency depends on the room size. If it's extremely hot and the room is large, you'll hardly feel any impact.
If you don't want to install an HVAC or can't afford it, you might want to invest in a portable air cooler, powered by a battery. This should be the easiest and the most budget-friendly way to avoid heat. You can use this device together with the purifier. As a pleasant bonus, some coolers might have a speaker and a USB port.

FAQ

Do air purifiers make a room colder?

No, most air purifiers cannot cool a room because they lack cooling mechanisms. However, if you opt for a combo device, it might make the premise cooler.

Do air purifiers work as fans?

Yes — but the directions of the air flow might differ. For summer, the forward direction would be optimal. For winter, you might opt for the upward direction because it might make the room hotter.

Do air purifiers help circulate air?

Yes, they do — but it's not their only mission. People buy them for the sake of filtration and ventilation. These devices remove dust and other harmful particles from the air, keeping it clean.

Do air purifiers make the room hot?

Yes, if we're talking about those that operate as fans with upward airflow direction. You might want to buy one to make your home warmer in the cold winter months. It should make the room hotter by pulling down the warm air from the ceiling.

Final Thoughts

The answer to the question "Do air purifiers cool down a room?" depends on the type of the device. Generally, purifiers lack cooling mechanisms. They just make the air cleaner without changing its temperature. Yet the two-dimensional fans of certain devices are powerful enough to cool down the room because they push out the air with considerable force.
