The Smartmi P1 air purifier showcases a sleek, modern design. It’s cylindrical in shape and demonstrates exceptional craftsmanship. The model I reviewed features a tasteful combination of silver with white accents at the base and top, while the display/control panel is a contrasting black.

What sets the P1 apart is its construction. It’s not just another plastic appliance; the purifier is encased in a metal housing, reinforcing its high-quality build and elegant appearance. Adding to its sophistication is an ECO leather strap, which is not only functional for carrying but also enhances its aesthetic appeal.

The Smartmi P1 is available in either silver or black, offering versatility in design preferences. The choice of silver is particularly noteworthy, as it’s a less common color for air purifiers but exudes elegance.

Control Panel

Smartmi P1 review

As an expert in air purifiers, I found the control panel and display of the Smartmi P1 to be particularly impressive. Here’s a straightforward breakdown of these features:

LED Screen Display: Clarity and Ease of Use

Atop the Smartmi P1 sits an LED screen display, which is central to operating the device and understanding its status. This display is crystal clear, making it easy to read the information it presents. The touch buttons integrated into this screen are highly responsive and precise, enhancing the user experience.

Intuitive Control Panel

The control panel of the Smartmi P1, located conveniently on the top, is user-friendly. It includes essential buttons like power, timer, and mode selection. Each button press is acknowledged with a beep sound, providing auditory feedback for your actions. The spacing of the controls is well thought out, allowing for accurate and hassle-free operation.

Informative Display Indicators

The display is more than just a control interface; it provides valuable information through various indicators. These include a pollen alert indicator, PM 2.5 level indicator (which shows particulate matter levels), and indicators for auto and custom modes. This array of indicators ensures that you’re always informed about the air purifier’s current functioning and the air quality in your room.

Additional Features: Light Sensor

An intriguing addition to the display is a light sensor. This sensor plays a role in how the purifier operates, which I’ll delve into more in subsequent sections of this review.

Size and Build of the Smartmi P1 Air Purifier

The Smartmi P1 air purifier has a weight of approximately 6.61 pounds. When you pick it up, the weight and the metal housing immediately give you a sense of its high-quality construction. It feels sturdy and well-made, a characteristic often associated with premium air purifiers.

Compact Dimensions

In terms of size, the Smartmi P1 measures 8.6 x 14.2 inches. This compact sizing makes it versatile for placement in various room sizes without taking up too much space. Its dimensions contribute to its ease of handling and mobility, allowing you to move it around as needed.

Features of the Smartmi P1 Air Purifier

The Smartmi P1 air purifier comes with several features that enhance its usability and effectiveness. Here’s a simplified overview of its notable features:

Sleep Mode: Quiet Operation

As someone who values a quiet environment, especially in the bedroom or while reading, I appreciate air purifiers with a sleep mode. The Smartmi P1 excels in this area. Its sleep mode operates extremely quietly, making it ideal for use in spaces where noise is a concern. You’ll find more details on its noise levels in sleep mode in the volume levels section of this review.


The Smartmi P1 includes a timer feature, allowing you to set it for 1, 4, or 8 hours. This is particularly useful for managing air quality without constant manual intervention.

Beyond the basic timer settings, the Smartmi P1 offers enhanced flexibility through its Smart APP. With the app, you can customize the timer in various ways, such as specifying activation times, days, and frequency. This level of control is a significant advantage for those who want to tailor the air purifier’s operation to their daily routines.

In summary, the Smartmi P1’s sleep mode and timer features add considerable value, catering to the needs of users who prioritize quiet operation and customizable settings. These features make the Smartmi P1 a versatile and user-friendly choice in the realm of air purifiers.

Light Sensor

The light sensor is conveniently located on the display panel of the Smartmi P1, right above the pollen indicator. Its primary function is to adjust the screen’s brightness automatically in response to the ambient light in the room. This adaptability is especially useful during nighttime.

For those who use the air purifier in a bedroom setting, the light sensor is a significant advantage. It ensures that the screen’s brightness is not overly bright or disruptive during the night. This means you won’t have to worry about the display illuminating the room or disturbing your sleep

Air Quality Sensor

The Smartmi P1 air purifier is equipped with an advanced air quality sensor, specifically a Laser Particle Meter sensor. This feature significantly enhances the purifier’s functionality and user experience. Here’s a detailed look at this aspect:

The air quality sensor in the Smartmi P1 is not just a standard feature; it’s a high-precision tool. During my testing, I was particularly impressed by the accuracy of this sensor. It’s located at the back of the unit and is designed to detect particles in the air in real time.

The laser particle sensor’s ability to monitor air quality in real-time is a standout feature. It ensures that the air purifier responds promptly and effectively to changes in the air quality, maintaining a healthy indoor environment.

Auto Mode

The Smartmi P1 air purifier’s auto mode is a convenient feature that works in tandem with its air quality sensor. Here’s a straightforward explanation of how it works:

When you set the Smartmi P1 to auto mode, the purifier automatically utilizes data from its air quality sensor to adjust the fan speed. This means the purifier intelligently adapts its operation based on the current air quality in the room.

In my use, I found myself frequently relying on the auto mode. The precision of the Smartmi P1’s sensor makes this mode highly effective. It adjusts the purification level as needed, ensuring optimal air quality without any manual intervention.

Given the sensor’s accuracy, the auto mode on the Smartmi P1 is dependable. It’s an excellent choice for anyone who prefers a ‘set it and forget it’ approach to air purification. You can trust the P1 to maintain good air quality automatically, making it a hassle-free addition to any space, whether it’s an office desk or a living room.

Smart Control

The Smartmi P1 air purifier stands out with its compatibility with popular smart home systems and additional smart features. Here’s a simplified overview:

Integration with Smart Home Assistants

The Smartmi P1 can be connected to well-known smart home systems like Google Assistant, Apple HomeKit, and Amazon Alexa. This integration allows for voice commands, adding convenience and a futuristic touch to your air purifying experience. For instance, you can ask Alexa to turn on the air purifier in a specific room or inquire about the current pollen index at home.

While integrating the Smartmi P1 with other smart home devices enhances its functionality, it’s important to note that this is optional. The Smartmi P1 works perfectly well independently, with its Smart APP providing comprehensive control and monitoring capabilities. However, if you already use devices like Amazon Alexa, connecting the Smartmi P1 can further streamline your smart home ecosystem.

Filter Reset Reminder

A particularly useful feature is the filter reset reminder, which is accessible through the Smart APP. To utilize this feature, you need to install the Smart APP and connect your Smartmi P1 to it. The app then keeps track of the filter’s lifespan and notifies you when it’s time for a replacement, specifically when the filter’s lifespan is at 10% or less. This feature is a great convenience, ensuring that you maintain optimal air purifier performance without having to manually keep track of filter changes.

Filtration Technology

The Smartmi P1 air purifier features an advanced 4-stage filtration system, crucial for its effective performance. Here’s a breakdown of each stage:

1. Preliminary Filter

  • Function: The first stage of filtration involves a pre-filter designed to capture larger particles like pet fur, dust, and hair.
  • Maintenance: It’s recommended to clean this filter every 14 to 28 days, which can be easily done using a vacuum cleaner or a dry cloth. Regular cleaning not only protects the subsequent filters but also ensures smoother operation of the device. For pet owners, frequent cleaning of the pre-filter is advisable.

2. Carbon-Infused Filter

  • Purpose: The second stage is the carbon filter, which is not made of carbon pellets but infused with activated carbon. Its primary role is to reduce various odors and harmful gases, including VOCs, cigarette smoke, pet odors, and food smells.
  • Maintenance: When the carbon filter becomes saturated, it may start to retain the odors it has absorbed. Exposing it to light and ventilation can partially rejuvenate its adsorption capacity. However, timely replacement of this filter is crucial for maintaining its effectiveness.

3. True HEPA Filter

  • Efficiency: The third stage is the H13 360° HEPA filter, capturing 99.97% of airborne allergens as small as 0.3 microns. This includes pollen, mold spores, dust, pet dander, microbes, and smoke.
  • Benefits: The True HEPA filter is particularly effective in trapping fine dust, mold, cigarette smoke, and other small particles. It also helps in reducing indoor air contamination and allergens, making it ideal for those sensitive to air quality.

Filter Replacement

  • Non-Washable: It’s important to note that the P1 filter is not washable and should never be cleaned with water.
  • Replacement Indicator: You can check the replacement filter availability on Amazon. Regular replacement of the filters as per the manufacturer’s recommendation is key to maintaining the air purifier’s efficiency.

Smartmi Smart APP

The Smartmi P1 air purifier offers enhanced functionality through its Smart APP. Here’s a simplified guide on how to use the app:

App Compatibility and Advanced Features

The Smart APP is available for both Android and iOS users. Once you connect your Smartmi P1 to this app, you unlock several advanced features. These include a more detailed timer, custom fan speed settings, and a handy filter reset reminder.

Downloading and Setting Up the App

To get started, download the Smart APP from Google Play or the Apple Store. After downloading, you’ll need to register. The registration process is straightforward – just follow the on-screen instructions to fill in your details.

Adding Your Device to the App

After registering, tap the ‘+’ icon in the middle of the app’s screen to add your new Smartmi P1. Select your device from the list and follow the on-screen steps to connect it. During this process, you’ll be asked to enter your email and a verification code, which you’ll receive after clicking on “Verification code transmission.”

Controlling Your Air Purifier Through the App

Once your Smartmi P1 is connected to the app, you can control it directly from your smartphone. When you open the app, you’ll see all connected devices on the home screen. Simply tap on your air purifier’s icon to access the main control screen, where you can adjust settings and monitor its performance.

Timer within the app

The Smartmi P1 air purifier offers a versatile timer function through its Smart APP and is designed for effective use in specific room sizes. Here’s an easy-to-understand overview:

Advanced Timer via Smart APP

With the Smart APP, you can set up an advanced timer for the Smartmi P1. This feature allows you to schedule exactly when the air purifier turns on or off. You can choose the specific times of day for operation, tailoring it to your daily routine.

Customizable Scheduling

The timer isn’t just about turning the device on or off at certain times. You can also program it to operate on specific days of the week. This level of customization means you can set the Smartmi P1 to work exactly how you want it throughout the week, ensuring your space is always purified according to your needs.

Room Coverage and CADR

The Smartmi P1 is designed for rooms up to 320 square feet. Its quick performance is largely due to its 250 m³/h CADR (Clean Air Delivery Rate) and an advanced wind tunnel mode. This means it can efficiently circulate and purify the air in a room of this size.

Although the Smartmi P1 is recommended for rooms up to 320 sq. ft., it has shown impressive results in slightly larger spaces during testing. So, if you’re considering using it in a bigger room, it’s worth trying out, as it may still perform effectively.

In summary, the Smartmi P1’s advanced timer feature and its suitability for rooms up to 320 sq. ft., with potential effectiveness in slightly larger spaces, make it a flexible and efficient choice for various indoor environments.

Pros and Cons

  • Luxurious design.
  • Premium build quality.
  • Smart APP compatibility.
  • Works with Google Assistant, Apple HomeKit, Amazon Alexa.
  • PM 2.5 and pollen detection.

  • Advanced timer.
  • Ozone-free operation.
  • Some features are only accessible via Smart APP.
  • Short power cord.


I’m really impressed with the Smartmi P1 air purifier. It’s not just its performance that stands out, but also some unique features I haven’t seen in other air purifiers. For example, being able to adjust the fan speed exactly how you want it is a great touch.

What’s also cool is that it works with Alexa, Siri, and Google. This means you can set it up, and then just let it do its thing, keeping your room’s air clean without you having to think about it.

The Smartmi P1 really brings together the best features you could want in an air purifier. It’s got great performance, a handy app, an air quality sensor, and lots of other premium features.

If you’re looking for a top-notch air purifier that not only freshens up your home but also lets you keep an eye on air quality in real-time, I highly recommend the Smartmi P1.
