Best Smart Air Purifiers – Tested, Reviewed and Ranked

Smart air purifiers have become increasingly popular in the market over time. More and more manufacturers are choosing to include innovative and smart options in their air purifiers, making day-to-day control easier.

These features range from fully automating the air purifier to connecting it to a voice assistant or advanced monitoring of the current air quality in the room.

However, smart air purifiers aren’t fundamentally different from classic ones; they are essentially the same but with added features like an air quality sensor, a smart app, and voice control (via Alexa, HomeKit, Google Assistant, or similar platforms).

From my personal experience, I have seen the advantages that smart air purifiers have over non-smart ones. They can be easily customized, automated, and remotely controlled. These advanced devices offer many options and benefits that are easy to get used to. For example, I like to set my air purifier to maximum speed a few minutes before I get home, ensuring I arrive at fresh, clean air.

We have tested many different air purifiers with different power, CADRs, filtration technologies, and smart options.

In this guide, I will explain in detail what smart air purifiers are, what features they offer, and what you can expect from them. Of course, I will also list the best smart air purifiers currently available for purchase.

Top 5 Smart Air Purifiers

After a detailed analysis and careful thinking, I have compiled a list of the five best smart air purifiers that you can get.

This list includes only air purifiers with outstanding smart apps, highly efficient filtration technology, and exceptional results in our performance tests.

Levoit Vital 200S – Innovative & Easy To Use App

The Levoit Vital 200S is the best smart air purifier you can get. It covers rooms up to 380 sq. ft. (35 m²) and cleans the air 4.8 times an hour in the recommended room size.

This air purifier uses the latest smart and innovative technology from Levoit. It features many built-in smart features, with the air quality sensor, air quality indicator, and auto mode being my favorites. The Vital 200S uses an infrared dust sensor that detects particles in real time.

One of the most exciting smart features is the ability to connect the Vital 200S with the VeSync smart app. This app raises your Vital 200S to a completely different level, unlocking many new possibilities that aren’t available through the physical controls on the device.

The most notable features include detailed air quality reports, automation, remote control, smart notifications, filter life checks, auto mode settings, scheduling, and more.

The VeSync app is available for Android and iOS devices.

The Vital 200S uses a three-stage filtration technology, has achieved outstanding results in performance tests, and is both very quiet and easy to maintain. It uses a 50W motor, produces only 41.0 dBA at the lowest speed, and removes all the smoke from the glass box in just 15 seconds.

Overall, the Levoit Vital 200S isn’t only the best-performing air purifier but also the best smart air purifier you can get.

Mila – The Smartest Air Purifier Ever

It’s true that I’ve said the Levoit Vital 200S is the best smart air purifier you can get, but that’s because it’s one of the best-performing air purifiers we’ve tested, with a well-optimized motor that also uses a feature-rich smart app.

However, when it comes to smart features alone, the Mila is undoubtedly the smartest air purifier I’ve ever used. It has numerous smart features and innovations, many of which are unique to this model.

Not only does the Mila air purifier have the most comprehensive smart app on the market, but it also includes one of the most accurate built-in air quality sensors. This sensor has nearly the same accuracy level as the Temtop laser particle meter, which we use in our everyday air purifier tests.

Through the Mila smart app, you can automate your device, control it remotely, view historical air quality data, and switch between various smart modes (such as energy-saving mode, household mode, white noise mode, sleep mode, etc.). You can even chat with the Mila AI assistant about your current air quality data.

I tested the Mila with The Big Sneeze filter, a HEPA filter air purifier option. You can also choose from eight different filter options.

Overall, the Mila is by far the smartest air purifier available on the market, and it is also a highly efficient and well-performing device.

Winix 5510 – Great Performance & Simple App

The Winix 5510 is the first air purifier from this brand that I’ve tested with smart app support.

Winix’s smart app is perhaps the simplest among all the ones I’ve tested.

It offers a remote control, an advanced timer, and a more detailed view of air quality data. The app is available for Android and iOS, and most importantly, setup and device pairing are smooth and issue-free.

Beyond the app, it’s worth highlighting that the Winix 5510 is one of the best air purifiers we’ve tested so far.

It delivers excellent performance in all our tests, features a highly efficient four-stage filtration system, and operates very quietly at lower speeds.

All in all, this is not just one of the best smart air purifiers—it’s also one of the best overall air purifiers we’ve reviewed.

Blueair 511i Max – Minimalistic Principles Enhanced with an App

The Blueair 511i Max is a modern, elegant, and highly efficient air purifier. With a CADR of 152 CFM (258 m³/h), it’s ideal for rooms up to 236 sq. ft. (22 m²).

It uses four-stage filtration technology, which is the core strength of this device and a key reason for its excellent results in our performance tests.

It earned a place in our guide of the best smart air purifiers not only for its impressive performance but also because it works with Blueair’s smart app.

The Blueair app offers full remote control of the device, detailed air quality readings, and advanced automation features.

What I particularly like is that it tracks air quality even when the air purifier is turned off.

Another great feature is the fan speed slider, which allows for fine-tuned adjustments between the preset speed levels.

This is similar to the manual mode available in the Xiaomi smart app.

Overall, the Blueair 511i Max is a high-performing smart air purifier, and it’s my top recommendation for small rooms such as children’s rooms, bedrooms, small living rooms, and similar spaces.

Xiaomi 4 Lite – Truly Powerful Smart App

Xiaomi makes some of the smartest devices out there, and the Xiaomi 4 Lite is no exception.

This medium-sized air purifier covers rooms up to 330 sq. ft. (31 m²), making it ideal for medium-sized spaces.

What I like about the Xiaomi smart app is its easy and straightforward setup, its wide range of features, and unique touches—like the fan speed slider.

It displays air quality data in a detailed and advanced way and even continues tracking air quality when the device is turned off.

In our performance tests, the Xiaomi 4 Lite delivered outstanding results. In our smoke test, it also performed exceptionally well—removing all the smoke from the glass box in just 14 seconds, which is even faster than its predecessor, the Xiaomi Mi 3H.

I’d say the Xiaomi 4 Lite is an excellent smart air purifier, but in my opinion, it’s better suited for users outside the US, mainly because replacement filters can be hard to find here.

The Xiaomi 4 Lite is perfect for medium and even large-sized rooms.

However, if you’re looking for something slightly smaller, check out our review of the Xiaomi 4 Compact, it might be a better fit for your needs.

Side-by-side Comparison of the Best Air Purifiers for Large Rooms

What Makes an Air Purifier Smart?

A smart air purifier is a device that features an air quality sensor, air quality indicator, auto mode, smart app, and other innovative options.

These air purifiers can be remotely controlled, track air quality in real-time, can be scheduled, automated, and much more.

So, with such a device you won’t only be able to track PM2.5, PM10, or VOCs in your air, but also to make it automatically remove this particle without touching any button or changing any setting.

Did I mention that smart air purifiers usually work with voice-controlled devices such as Alexa, HomeKit, and Google Home?

How Do Smart Air Purifiers Work?

Essentially, smart air purifiers work the same way as traditional 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 may be 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 recommend is to decide whether you want an air purifier that uses proven 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 to 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.

Scheduling: 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.

Auto mode: this type of device almost always has an auto 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 air purifier with auto mode that you won’t have to lift a finger to operate?

However, if you are looking for the smartest air purifier ever, then my vote would go to the Mila air purifier.
