Smart air purifiers have become increasingly popular in the market over time. More and more manufacturers choose to include innovative options in their air purifiers. Smart air purifiers make day-to-day control easier, whether by fully automating the air purifier, connecting it to a voice assistant, or just monitoring the current air quality in the room.
Most importantly, smart air purifiers are not different from standard air purifiers. They’re basically the same air purifiers but with extra smart features like an air quality sensor, a connection to a smart app, or the ability to connect to the voice-controlled device. In addition to the smart add-ons mentioned above, depending on the technology and the brand, smart devices use HEPA filters, carbon filters, ion filters, or any other filtration technology available on the market.

The Levoit Core 400S is the first air purifier on the best smart air purifiers list. Levoit adds a new air purifier to its product range every so often. I think this is the company that launches new air purifiers most often, and they come with a lot of new features.
I have tried most of the Levoit air purifiers. Still, the one that stood out to me as the most exciting model is the Levoit Core 400S. A high-quality device that comes with many options and has fantastic performance. That’s why I decided to put the Core 400S on the list.
Levoit Core 400S is a beautiful device with modern looks. You can easily find the best spot for it in any room. On top of the high performance in air purification, this device brings refreshment to the room itself.
The Levoit Core 400S uses the VeSync app available on Android and iOS devices. This advanced app is used to connect all Levoit air purifiers.

The Airdog X3 is an innovative air purifier that stands out from the other air purifiers on the list, mainly thanks to its filtration technology. This air purifier uses collection plates as the primary filtration stage; these plates are like a magnet that collects all particles from microorganisms to dust.
The collection plates use graphene to improve efficiency, which can attract particles up to 0.0146 µm in size, which is 6 times more powerful than a traditional air purifier. The Airdog X3 is an air purifier that has impressed me in many ways, which is one of the reasons why it is on the list of the best air purifiers with washable filters.

Essentially, the Mi Home app is designed for all Xiaomi devices. You can literally program your Xiaomi to work however and whenever you want via the Mi Home app. For example, you can set Xiaomi to switch off if PM2.5 drops below 25. The Xiaomi Mi 3H uses 3-stage filtration, responsible for the outstanding performance that the Xiaomi Mi 3H has shown in the tests I have conducted.
The device has a screen and only one control button, and all advanced options are set and managed via a smartphone app.
I highly suggest looking at the logo and brand when buying the air purifier. If you look at the Xiaomi Mi 3H and Airdog X3, you can see that these two devices are identical in their looks.

The Aura Air smart app offers some innovations that apps from other devices do not have. In addition, there are standard options such as displaying the current air quality, air quality charts by day, and commands to control the device.
What sets the Aura Air app apart is the personalization, notifications, and suggestions you receive via messages on your mobile device based on your current air quality and the settings you chose when you set up the app. Personally, the most unusual thing about this air purifier, and the only thing I would change, is that the device does not have an option to switch off.
Aura Air is a unique device, and you can’t compare it to other devices on the list because this one is mounted on the wall. By being mounted on the wall, it fits perfectly in crowded rooms.

What Makes an Air Purifier Smart
Most air purifiers, not just smart ones, usually have sensors that estimate the density of various air contaminants such as nitrogen dioxide (NO2 is a toxic gas created mainly from car and power plant exhaust), PM2.5 (particles smaller than 2,5 microns, including industrial emissions and tobacco smoke), PM10 (particles up to 10 microns in size, including dust, mold, and pollen) and VOCs (volatile organic compounds, or potentially dangerous gasses from things like cleansing products and dyes).
In addition to the built-in smart sensor, what makes an actual smart air purifier is the ability to connect to a smart app and automatically purify the air.
How Do Smart Air Purifiers Work?
Essentially, smart air purifiers work the same way as conventional air purifiers. Just because an air purifier is smart doesn’t mean it cleans the air in your room better than a regular air purifier. But smart air purifiers are more energy-efficient (because of auto mode).
They display information about your current air quality and can be programmed to your exact needs. Plus, you can control them from a remote location, at any time, as these devices are mostly connected to your home WiFi.
Smart air purifiers work by downloading the manufacturer’s mobile app on your Android or iOS device, launching it, and connecting it to the air purifier. Connecting the app and the device opens up many new possibilities. It gives the device full power and the ability to reach its full potential.
How Do Smart Air Purifiers Detect Air Quality?
Smart apps almost always have an excellent graphical interface that shows, among other things, the current air quality in the room. Given that smart devices mostly have an air quality sensor alongside the app, it is not surprising that apps have this capability. Firstly, it is much easier to read the app’s data and filter it by day than it would be on a screen located on the device itself.
However, many devices have indicators that light up in different colors depending on the air quality and a display that shows the current AQI or the current amount of PM2.5 in the air. The air quality indicator in smart air purifiers usually has a separate motor that draws air in to constantly check the air quality, regardless of the operation of the air purifier. This sensor mostly has lasers that detect the number of particles or VOCs in the air.
Choosing the Best Smart Air Purifier
To choose the best smart air purifier, you first need to decide what kind of air purifier you need. Based on that, select a device on the list of the best smart air purifiers provided in this article. I have indeed chosen all the devices on the list very carefully, and you won’t regret whichever one you choose, but there are some things you need to keep in mind.
The first thing I would advise you to do is to decide whether you want an air purifier that uses classic filters such as HEPA and carbon filters or whether you still want a slightly different air purifier that uses new, innovative technologies, an ionizer, or UV-C filtration.
In addition, room coverage is critical, so it would be advisable to know how large a room you have and buy an air purifier dedicated for that room size. If you buy a weak air purifier, it could be inadequate and insufficient to clean the air in a room larger than the recommended dimensions.
A final suggestion is to consider the air purifier’s maintenance and filter replacement costs.
In short, if you don’t have a favorite to buy yet, specifying the items I suggested earlier will help you narrow down your choice and make the decision easier. Suppose you still want to do more research. In that case, I recommend you read the individual reviews of these devices on the Air Purifier First website.
Advantages of a Smart Home Air Purifier
Smart air purifiers have many advantages, but there is only one thing that could be a disadvantage: the price, which is slightly higher with smart air purifiers than with conventional ones. However, this type of device has so many advantages that I think most users won’t be bothered by the price.
Real-time air quality: smart air purifiers work in combination with an air quality sensor and display the current air quality in the room at any time on your smartphone, on the screen of the device, or in the form of LED indicators.
Schedule: almost all smart air purifiers have the option of advanced timer settings. So you can decide when you want the device to turn on or off. However, some of the devices on the list have several additional options, allowing you to fully program the air purifier’s operation.
Additional options: Almost all of the air purifiers I have tested have some hidden options that are only available if they are connected to a smart app. Sometimes these options can only work in the smart app, such as daily air quality charts. It is simply impossible to install so many options and controls on the device itself.
Filter reset indicators: smart devices tend to have much more detailed filter reset indicators, so you can see the current filter wear at any time. For non-smart air purifiers, you don’t have this option, but simply wait for the LED indicator to let you know when it’s time to change the filter.
Voice control: these devices take control to the next level and are technology compliant, so you can easily connect most smart air purifiers to Amazon Alexa and Google Assistant, while some can even connect to Homekit.
Remote control: smart air purifiers have WiFi, so they connect to your home network. This means you can control this type of device from any location, meaning you don’t have to be at home to turn it on or off. You can even check the current air quality in the room through the internet.
Automatic mode: this type of device almost always has an automatic mode, which works in combination with the air quality sensor to switch the device’s operating mode according to the current air quality. Is there a better solution for clean and high-quality air than an automatic air purifier that you won’t have to lift a finger to operate?
FAQ on Best Smart Air purifiers
Are smart air purifiers a waste of money?
No, they are definitely not. We live in a fast-paced world dominated by technology, and we are used to smart devices that make our lives easier. This idea is also behind the smart air purifier, to display as much information as possible and make the daily use of the device easier.
Can any smart air purifier connect to Alexa?
Whether the manufacturer has made this a feature in the app, the device can easily connect to Alexa, Google Assistant, or even Homekit.
Does every smart air purifier work with HomeKit?
Unfortunately, it doesn’t. To work with the HomeKit, an air purifier must be approved and authorized by Apple. Almost every smart air purifier works with Android and iOS devices, but not necessarily with the HomeKit.
