Best Air Purifiers with Sensors in 2023

If you want full control of the air quality in your home, you can consider getting air purifiers with sensors.

These devices, simply known as smart air purifiers, do wonders for air quality.

Air pollution causes millions of deaths every year, so breathing in fresh and clean air should be a top priority for everybody nowadays.

Considering the current pollution levels worldwide, it can be hard to escape them.

And on top of air pollution, we also have to deal with dust, pollen, mites, and other particles floating around the air that cause allergic reactions in some people.

I’ve learned that getting an air purifier for your home is one of the best ways to ensure you breathe clean air.

In this article, I’ll show you some of the best smart air purifiers with sensors on the market today to make it easier to choose the right one.

But before that, we must first determine what they are. So, read on to learn more.


What Are Air Purifiers with Sensors?

So, what makes an air purifier “smart”?

Nowadays, we have many smart devices, but only a few people know why these gadgets are called smart devices.

The main characteristic of a smart device is its ability to effectively communicate and share information with its user and other smart devices.

For example, suppose you have a smart air purifier. In that case, it will likely have an air quality monitor and will constantly display the current air quality in a room.

These air purifiers usually do this through simple LED indicators that change color depending on a room’s air quality and particle levels.

However, there are smart air purifiers that take this a step further by having a full LED display that shows you accurate and timely information about the room’s air quality.

On top of that, I’ve seen some models that can connect to your phone via Wi-Fi, allowing you to view information and tweak the air purifier’s settings through an app.

In fact, many modern smart air purifiers connect to devices like Alexa or Google Home, allowing you to speak to the speakers and turn the air purifier on, off or change the settings.

Smart air purifiers make it much easier to clean the air at home.

With a smart air purifier, you can access more information and constantly monitor the air quality at home.

This allows you to change the air purifier’s settings depending on the air quality, increasing the fan speed whenever the air quality is poor and lowering the speed when air quality is high.

Additionally, some smart air purifiers even send you notifications when it’s time to replace or check on your filter, which makes air purifier maintenance much easier.

Now that you know what a smart air purifier is, you might wonder how to find the best one.

Don’t worry – in the next section, I’ll explain all the features that make an excellent smart air purifier.

What Makes Good Smart Air Purifiers with Sensors?

You’ll find many options when you shop for smart air purifiers with an air quality monitor.

Nowadays, more people pay attention to the air quality at home, which is why you’re spoiled for options when buying smart air purifiers.

That said, I’ve noticed that not all smart air purifiers are up to par.

In fact, quite a few available models don’t make the cut if you’re looking to effectively clean the air.

And since air purifiers are a very important appliance nowadays, you must pay close attention to the features when buying a smart air purifier.

So, what are the features you need in a smart air purifier?

Well, that will always depend on your needs.

However, here are some of the most important features you must have in a smart air purifier.

Air Quality Monitor

An air quality monitor is the most important feature of a smart air purifier.

Remember, smart air purifiers should relay information to the user or other smart devices. 

And without an air quality monitor, the air purifier probably won’t be able to relay any useful information your way.

Whenever someone asks me for tips when buying a modern air purifier, I emphasize the need for an air quality monitor.

If your smart air purifier has a good air quality monitor, it will constantly give you air quality readings.

This allows you to gauge whether or not the air is safe to breathe and if you need to change the settings to clean the air more efficiently.

While this isn’t the only feature of a smart air purifier, it’s the most important. 

Without it, you won’t get as many benefits from your air purifier.

Wi-Fi or App Connectivity

Another useful feature I suggest looking for in a smart air purifier is Wi-Fi or app connectivity.

Normally, air purifiers that connect to Wi-Fi can communicate with other smart devices in your home.

For example, if you have an Alexa or similar smart speaker, you can connect your air purifier to the device.

Once you do this, you can use your voice to turn on the speaker, change the settings, or even shut it off.

This makes it much easier to use the air purifier and will help bring your home into the future.

On top of Wi-Fi connectivity, it would be great if the air purifier come with a partner app.

Many air purifiers can connect to your phone via an app nowadays.

And when you open the app, you can see the room’s air quality in real time while adjusting the settings from your phone, all without leaving your spot.

This is a signature feature of most smart air purifiers.

So, if you’re looking at a smart air purifier with no Wi-Fi or App connectivity, it might be best to look at other options.

High-Quality Filtration

This is one of the features you need to have, regardless of whether you’re getting a smart air purifier or a normal model.

This is because air purifiers only work when they have high-quality filtration systems.

Air purifiers are just fans that push air through certain filters.

These filters capture any airborne particles that might cause trouble, such as PM 2.5, foul odors, dust, mites, and even pollen.

Paying close attention to the filtration system is important to ensure that your air purifier can capture all the particles that cause you trouble.

Your air purifier should have a multi-stage filtration system with a HEPA filter for dust, mites, and PM 2.5 and a carbon filter to absorb strong and foul odors.

Without these specific filters, your air purifier won’t be able to clean the air efficiently.

This is why the filters are a major consideration when buying an air purifier, even if you plan on buying something other than a smart model.

Now that you know what smart air purifiers are and the features to look for in a good one, it’s time for me to talk about some of the best smart air purifiers on the market.
