Do I need an air purifier if I have an AC?


Do I need an Air Purifier if I have an AC? The short answer is that yes, you do. The job of an air conditioner is to reduce the temperature in a room so that it’s comfortable for you.

This means they can’t clean dust or pollen from it like a purifier would be able to do so accordingly; also, keep in mind these devices don’t remove VOCs such as smoke and gases either.

So make sure there aren’t any particles floating around before turning on both appliances at once!

What are air conditioners used for?

Air conditioners are devices that constantly work to chill your room. They use heat exchange methods by sucking in hot air and exchanging it with refrigerant liquid through pipes within the machine before releasing cooled air back into its original area of residence (a process called “refreshing”).

The water vapor present is also removed during this operation, so you can feel refreshed after cooling down!

What are air purifiers used for?

Air purifiers are appliances used to clean the air in your home. They use different methods for particle collection, depending on their model and manufacturer, but most often, they include a combination of HEPA filters with carbon filters or ionic mechanisms too. These will capture any harmful contaminants present so that you can breathe fresh air!

Air purifier vs. air conditioner

Air purifiers and Air conditioners are two different appliances, but both of them have their distinctive purposes. An air purifier is a device that cleans the air in your home. It gets rid of allergens, contaminants, and other things that are bad.

That means purifiers can remove odors or gases from the Air too! This makes them a good addition to your home if you have pets, someone at home is smoking cigarettes, or you own a fireplace. Meanwhile, an air conditioner’s main use is simple: it changes the temperature of the room where it is installed so that people feel comfortable!

Of course, they can’t remove substances from the Air – just temperatures – which is why they aren’t the best choice for people with pets or smokers but are good if you want to make your home cooler.

Air Conditioners and Indoor Air Quality

So what effect do Air Conditioners have on Indoor Air Quality? One of the most important issues in heating, ventilating, and air conditioning (HVAC) is IAQ—Indoor Air Quality. The need for this concern has been brought on by the fact that people are spending an average of 90% of their time indoors. When you spend that much time in one location, it’s important to make sure your indoor air is up to par.

Cleaning this Air prevents allergies and other health issues in the people breathing it and improves comfort by allowing for better temperature control and reducing the amount of dust floating around.

The reason that clean Indoor Air is so important has to do with how pollutants behave in an enclosed area. Single-family homes don’t have a roof and walls, which means the air cannot go in or out. This means that pollutants are more likely to stay indoors.

While it might seem counterintuitive, running an Air conditioner can actually have adverse effects on IAQ. Since they remove humidity from the air, they can create an environment where humidity is low enough for mold to develop. What’s more, If you live in a humid environment, when you open your windows on cold surfaces, condensation can form. Mold and fungus are more likely to grow in these conditions.

Another effect of using an AC is that it can lower indoor humidity levels to as low as 20%. This is a problem because too much moisture can lead to condensation and mold growth on windows, walls, and other surfaces.

The solution: While air conditioners have negative effects on IAQ, they can be mitigated by using an air purifier. An air purifier will help to remove allergens and pollutants from the air while also increasing humidity levels (and potentially eliminating condensation) by reintroducing moisture into the room.

What makes Air Conditioners unsuitable as Air Purifiers?

Air Conditioners are designed to cool down rooms with relative ease. The more Air they can pull in, the faster your room will feel cooler! Imagine if you had an Air Purifier next door that filtered out all sorts of pesky pollutants – this would reduce how much outdoor Air reached inside our house and make it harder for us to use our ACs efficiently because now only cleanroom-quality stuff goes through them (and trust me when I say there’s plenty).

Why do I need an Air Purifier in a room which has an Air Conditioner?

In short, an air purifier helps prevent the negative effects of Air Conditioners on IAQ. In a room with both an AC and an air purifier, you’ll enjoy clean Indoor Air that feels good and is healthy for your family to breathe!

An air conditioner’s main function is changing temperatures – not removing particles from the Air or upgrading indoor air quality. You’ll notice that when you run your AC, three things happen:

1) There’s a sudden rush of cool air into the room, and the dust in the Air is blown all over your house!

2) The temperature starts to drop until it hits that sweet spot where it feels just right.

3) The fan may slow down or turn off entirely, but the compressor keeps humming on.

As you can see, if your AC is on its “cool” setting, it will suck in a lot of outdoor Air and push that dust around your house! That is why, if you have an Air purifier nearby, dust will be more likely to enter the purifier rather than your air conditioner.

Sometimes when your AC turns on, dust from outside will get in. Pollutants also move from areas of high concentration to low concentration. As mentioned earlier, this can increase the humidity of your home, which can lead to more mold growth.

On the other hand, an air purifier is designed to remove pollutants from the Air. This means that even in its lowest setting, it will continue working throughout your AC’s operation. And since your AC is pulling in a lot of fresh outdoor air, you don’t have to worry about it bringing in too much dust; the purifier will eat them up before they reach your AC unit.

If you’re having trouble deciding which device to use at home, think about what kind of pollutants you want to keep out of your house. If you’re looking for a way to keep pollen and other outdoor allergens out of your house, an air purifier is the most effective option. However, if you’re more concerned about dust and particles in the air, then an AC with a HEPA filter is for you!

Can I use an Air Conditioners with a built-in Air Filter instead of an Air Purifier?

If you’re looking for an air purifier, but your AC has a HEPA filter already, then go ahead and use it! You can enjoy the perks of both devices at once.

An air purifier with a built-in HEPA filter will help take care of your IAQ by removing allergens from the Air. An AC with a built-in HEPA filter (like Mitsubishi’s Cool and Quiet Split Air Conditioner ) will keep your house cool while also preventing dust from reaching it!

Of course, there are other factors to consider, such as whether or not an AC unit is right for you. (Maybe your room is too big!) But you don’t have to buy an AC and an air purifier separately anymore. That’s like buying a TV and VCR separately when you can just get one device that does both!

Why are air conditioners not suitable for air purification?

This is because an air conditioner by design withdraws outside Air into the room. When the AC unit switches on, it releases this same dirty outdoor Air back into your house. An

Air conditioning cools things. It is like a vacuum cleaner because it sucks in air and takes the hot air to the outside. Although some units have built-in HEPA filters, they do not work like an air purifier and cannot remove pollutants from your indoor environment.

Which is better: an air purifier or an air conditioner?

It’s important to consider your home and lifestyle when deciding between an air purifier or AC. If you’re looking for something that will remove particles like pollen, allergens, dust, and pet dander from household air, then opting for a high-quality air purifier is the way to go.

A good air purifier can reduce the number of pollutants in the air, so if you have allergies or asthma, this will be a great investment!

On the other hand, an air conditioner is more suitable for those who want to cool down their house. In order for your AC to function properly, it needs to bring in outside air from time to time.

If you don’t want a lot of dust and other pollutants in your house, then using an air conditioner with a built-in HEPA filter might be the way to go. Because the device cools down your home, you do not need to worry about dirty air coming inside!


1. Do air conditioners bring in Air from outside?

Answer: Yes! An air conditioner draws in fresh air from outside and releases it back into the home to cool your room. This means that there is a chance of bringing outdoor pollutants into the house.

2. Can I use an air purifier with an air conditioner?

Answer: Yes! An air purifier with a built-in HEPA filter can help remove particles from the air, including dust and pet dander.

3. Do air purifiers cool the Air?

Answer: No, they do not. An air purifier with a built-in HEPA filter does not have an AC function. It only helps remove pollutants from the room.

4. Do air conditioners purify the Air?

Answer: No, they do not. An AC unit only has a cooling function, so it does not remove pollutants in the Air. However, some units have a built-in HEPA filter, which can help remove large particles from the Air.

5. Is an air purifier required inside an Air-conditioned room?

Answer: No, you do not need to use an air purifier in conjunction with an AC. An AC unit will cool your room, while a HEPA filter will remove particles from the Air.

6. Can we use AC with an air purifier?

Answer: It is not recommended to use an AC in conjunction with a purifier. An air purifier will help remove pollutants inside, while an AC unit cools your room. By using both devices, you will be exposing your family to unfiltered Air.


Do I need an air purifier if I have an AC? Yes. An air purifier can help if you have allergies or asthma, but it will not replace the function of an AC in a hot climate.

In fact, some studies show that using both may actually be more effective for managing pollen and other allergens than relying on one alone.

If you live somewhere with high levels of pollution from cars or factories, then your indoor environment is also likely to suffer from increased pollutants as well. That’s why we recommend getting a dual system unit that includes both an air conditioner and a HEPA filter!

Suppose you’re looking for a high-quality air purifier and AC. In that case, we recommend: Winix 5500-2 Air Purifier with True HEPA Filter & Haier HPRB08XCM 8,000 BTU Portable Air Conditioner with Remote Control because both of these units are powerful and affordable!
