Smartmi is a brand that offers a diverse selection of products for the home. Their main products are air purifiers. One of their devices that I tested and whose detailed review you will read below is the Smartmi P1 air purifier.
The P1 is a new model, slightly smaller than its predecessor, but with some new options and features that the previous model did not have. My first impression when opening the shipping box was wow. I was thrilled with the premium design of this device.

Smartmi P1 Specifications
Below is a complete list of important specifications and features included on the Smartmi P1 Air Purifier:
|Dimensions||8.6 x 14.2 inches (21,8 x 36,1 cm)|
|Filters||Pre-filter, True HEPA Filter, and Carbon-infused Filter|

The Smartmi P1 is an elegant air purifier. The device looks luxurious and premium. The device has a cylindrical shape, sleek design, and top-quality workmanship.
In this review, the model I tested is silver, with white elements on the bottom of the device and the device’s top. Besides, the display/control panel is black.
P1 is not entirely plastic; it is lined with metal housing, which confirms the elegance and high-quality build. The Smartmi P1 uses an elegant strap made of ECO leather to carry the device. This strap gives an extra dose of elegance to the device.
The Smartmi P1 can be selected in silver or black color. Not many manufacturers choose a silver color; I noticed that with the Medify MA-15 air purifier, too. In my opinion, silver is an elegant and great choice, although I prefer white. In essence, the P1 is a lightweight, elegant, and attractive air purifier that will fit into almost any environment.
Control Panel & Display
There is an LED screen display on the top of the device. The screen display is used to control and get info about the device’s current state. It contains indicators and touch buttons.
The screen is excellent and provides superior readability. The touch buttons are also of outstanding precision.
There are buttons on the screen display: power, timer, and mode selection buttons. Each time you press the button, you will hear a beep sound. The controls are perfectly spaced, which provides precision on a button press.
The display also shows the indicators: pollen alert indicator, PM 2.5 indicator, PM 2.5 level, auto mode indicator, custom mode Indicator, and buttons’ Indicators.
The display contains a light sensor in addition to the indicators and buttons. I will write more about it in the next Smartmi P1 review paragraphs.
I can say that the airflow in the Smartmi P1 is standard as in similar cylindrical air purifiers, such as the Levoit Core 300.
The Smartmi P1 draws air in through holes in the device’s bottom.
The air then passes through filters. Filtered, clean air exits through the grilles on the device’s upper side, moving vertically.
Size and Dimension
The air purifier weighs about 6.61 lb. When you take the device in your hands, you will immediately feel that you hold a high-quality air purifier, primarily because of the metal housing and weight. The dimensions of the device are 8.6 x 14.2 inches.
What’s in the box?
When you buy the device, you get a 1x Smartmi P1 air purifier, 1x 4-in-1 H13 HEPA filter, 1x power adapter, and 1x user manual.
In my opinion, this is all that should come with one device. Especially when we consider that the device comes assembled and does not need any additional settings. Take the device out of the box, plug it in, and turn it on.
Personally, I prefer devices that offer the sleep mode option. Primarily because I am the type of person who likes to use an air purifier in the bedroom or in a room where I often read books. These are rooms where any slightly louder sound can interfere. That is why I always prefer quieter air purifiers and sleep mode devices.
The Smartmi P1 sleep mode is extremely quiet. You can read how loud is the Smartmi P1 when it is turned on in sleep mode in the section with volume levels at all speeds.
The Smartmi P1 uses a timer as one of the advanced options. The timer can be set to 1h, 4h, and 8h.
However, P1 offers additional timer settings via Smart APP. The timer can be set in a surprising number of ways, so you can specify when to turn the device on or off, which day, how many times during the day, and so on.
A light sensor is an exciting and useful option, especially if you are like me and like to use an air purifier at night in the bedroom. The light sensor is on the screen, immediately above the pollen indicator. Screen brightness adapts automatically based on the surrounding conditions, thus evading unwanted night-time brightness.
Air Quality Sensor
An air quality sensor is an advanced option. The Smartmi P1 uses a Laser Particle Meter sensor.
I tested the sensor’s accuracy, and I can say that I am surprised by its accuracy.
Given the sensor’s extreme accuracy, you can easily trust that the Smartmi P1 will do the job for you when you leave it working in auto mode.
How to Clean the Air Quality Sensor?
Air quality sensors need to be cleaned periodically. If you use an air purifier in a heavily polluted environment, you need to clean it more often.
First, turn over the air purifier and remove the filter. Then, use a screwdriver to loosen the screws on the sensor cover. Remove the plastic cover and clean the inside with a hairdryer, but do not use hot air. Once cleaning is finished, put everything back as it was.
Air Quality Indicators – PM 2.5. and pollen
The air quality sensor is connected to the screen display to display air quality in real time. The real-time reading of PM 2.5 particles is shown in the middle of the screen.
Above is a display of the concentration of pollen in the air. This indicator can glow in different colors and display the air’s current pollen pollution. Green color – perfect. Yellow color – good. Orange color – moderate. Red color – unhealthy.
Auto mode is another option that is associated with an air quality sensor.
Suppose you switch the Smartmi P1 to auto mode. In that case, the device will automatically collect information from the sensor and determine the required fan speed based on it.
This is the mode I use most often. The Smartmi P1 sensor is extremely precise, so the auto mode is also precise. I’m sure that the P1 won’t let down anyone who decides to use the device auto mode all the time.
Smart Control with the Help of Google, Siri, and Alexa
Another attractive option that I would single out is connecting the Smartmi P1 air purifier with many well-known home smart systems such as Google Assistant, Apple Homekit, and Amazon Alexa.
For example, that means you can tell Alexa: “Hey Alexa, turn on the air purifier in the kid’s room?” or if you want some other information, you can ask Alexa: “Hey Alexa, how is the pollen index at home?”.
I would like to emphasize that combining smart home devices is arbitrary and that you do not have to have any of these devices for the Smartmi P1 to work. The Smart APP offered by Smartmi will be enough for almost all situations. Suppose you have Amazon Alexa in your home. In that case, this is an opportunity to attach another device to it and make your home even smarter.
Filter Reset Reminder
The filter reset reminder only works in combination with the Smart APP. This means you need to have a Smart APP installed on your device and connect P1 to the app. Then, at the bottom of the screen, you will have information about the filter duration.
My recommendation is to install the app, connect the device, and enjoy all the app’s benefits. Especially since you won’t have to think about when it’s time to replace the filter. The app will send a reminder when the filter’s lifespan reaches 10% or less.
Smartmi Smart APP
The Smartmi P1 offers the ability to connect to the Smart APP. As soon as you connect to the Smart APP, new advanced options will be available to you.
The application is available for Android and iOS platforms. Some of the advanced options available with application installation are an advanced timer, custom fan speed mode, and filter reset reminder.
Installation and Registration
You can download the app from Google Play or the Apple Store. After installation, you need to register. Check the picture below; it shows the registration steps and how to fill in which data.
Immediately after registration, you need to press the plus in the middle of the screen and connect the new device to the application. Then, select the device, and follow the instructions on the screen.
Control Smartmi P1 With Application
Once you have successfully connected the air purifier and the application, new possibilities open up for you. After launching the application, the devices connected to the application will be displayed on the initial screen. Pressing the device icon opens the main device control screen.
The control screen consists of several units:
At the bottom is the filter reset indicator. Clicking on the two arrows above the filter reset indicator opens additional options. Among many other things, there is a timer option.
Just above are the buttons for controlling the device. There is the power button, auto, Level 1, Level 2, and manual/custom mode.
Above the buttons is a picture of the device, above which is the indicator that shows real-time air quality.
A manual mode is an innovative option, which I have not noticed in other air purifiers. When you switch the device to manual mode, a “bar” with a circle will appear on the right side, through which you adjust the fan speed.
You can add an advanced timer via the Smart APP. You can add a timer by choosing when you want the device to turn on or off, at what time of day. You can basically choose the exact time to turn it on or off.
You can also set the timer to turn on or off on certain days. With the advanced timer’s help, you can program P1 as you want it to work throughout the week.
Room Coverage and CADR
Smartmi P1 is intended for rooms up to 320 sq. ft. The performance is fast, mostly thanks to the 250m³ / h CADR and advanced wind tunnel mode.
Suppose you plan to use the P1 in larger rooms. In that case, you can try because, in the tests performed, the device made excellent results in slightly larger rooms than the recommended dimensions.
The filter is an essential part of every air purifier. The Smartmi P1 uses an advanced 4-stage filter located on the lower half of the device. It is cylindrical in shape and hollow in the middle. The P1 filter is not washable, so it should not be washed under any circumstances.
The pre-filter is the first stage of filtration.
The pre-filters primary purpose is to capture pet fur, large dust particles, and hair. The pre-filter should be cleaned on average between 14 and 28 days. This will protect other filters, extend their lives, and make the device more comfortable to operate. You can clean it with a vacuum cleaner or a dry cloth.
My recommendation is that if you have pets, clean and check the pre-filter as often as possible.
The carbon filter is the second stage of filtration. The carbon filter is not made of carbon pellets. Carbon filters’ primary purpose is to reduce VOCs, cigarette fumes, harmful gas, pet odors, food odors, and other unwanted smells.
True HEPA filter
The H13 360 ° HEPA filter is the third stage of filtration. True HEPA filter captures 99.97% of airborne allergens, including pollen, mold spores, dust, pet dander, microbes, and smoke. In fact, all particles as small as 0.3 microns in size.
With an H13 HEPA filter, this air purifier can assimilate smells, gas, TVOC released from everyday products, and particles like pollen and dust, freeing you from indoor air contamination and disturbing allergens. True HEPA will also trap fine dust, dust particles, mold, and cigarette fumes.
How to replace the Smartmi P1 filter?
The P1 filter is changed between 6-12 months, as recommended by the manufacturer. When you connect the device to the Smart APP, the percentage of filter damage and the time it will take to replace it will be displayed at the bottom of the screen. This is great because you can easily get organized around buying a new filter. You don’t have to think about when a filter will stop working. You can predict it with the help of the app.
My advice is to periodically vacuum the inside of the air purifier (where the filter is located) with a vacuum cleaner, thus extending the device’s efficiency and the filter’s life.
Total time: 5 minutes.
Turn off P1, unplug it, and turn it upside down. Immediately unscrew the bottom cover, and remove the old filter from the device.
The next step is to vacuum the inside of the device with a vacuum cleaner to remove any dust.
Unpack the new filter and prepare it for installation. Immediately afterward, a new filter needs to be inserted into the device and the lid closed.
The last step is to reset the filter. You need to keep your finger 5s on the mode change button.
In my opinion, it is a big plus if the air purifier has more speeds. Therefore, I am delighted with the Smartmi P1 possibilities for adjusting the fan speed.
In addition to the standard modes that you can turn on directly on the device, a manual mode is turned on via the Smart APP. In addition to all that, there is also a sleep mode, which is extremely quiet, so you can easily use the Smartmi P1 in the bedroom or any other room that requires silence. However, that does not mean P1 is not great for some other rooms like the living room, kitchen, or children’s room.
The P1 is extremely quiet in sleep mode, producing 40.9 dBA of sound.
In normal mode, it produces a sound of 46.8 dBA, while at maximum speed, it makes a sound of 62.3 dBA. Below you can see a table with all the measurements. My measurements may differ from the manufacturer’s measurements because I perform measurements at home, not in the laboratory.
|Sleep Mode||40.9 dBA|
|Normal Mode||46.8 dBA|
|Max Speed||62.3 dBA|
I tested the Smartmi P1 air purifier for a while in all the rooms in my home.
I often used the device in the living room and in the bedroom. I would occasionally move it to the kitchen if needed. Thanks to the practical transfer handle, switching from room to room is not a problem. However a better option would be to buy more devices and manage each one separately with a Smart APP.
I mostly used P1 in auto mode.
However, below I will show you the well-known test I regularly perform, which you already know if you are actively following the Air Purifier First website. I will conduct the tests in the two rooms that I think are most important.
194 sq. ft. Room Test
I tested the Smartmi P1 in a 194 sq. ft. room. P1 worked for 60 min. It was turned on at the highest speed all the time, which I set by turning on custom mode via the smart app and setting it to maximum speed. P1 improved the room air quality by about 95% during the mentioned time, lowering the AQI from 137 to 7.
This is a fantastic result. I can say that I expected something similar because of the first impression I got as soon as I opened the device. Below is a table with details and a display of all values before and after.
|#||Starting Baseline||After 60min|
320 sq. ft. Room Test
After the first test, I tested the Smartmi P1 in a room of 320 sq. ft.
This room is of the recommended dimensions, so this is a reliable test. The P1 air purifier worked for 60min. It lowered the AQI from 131 to 12, thus improving air quality by an incredible 91%. This is a fantastic result, and I can say that P1 did not let me down in this test either.
|#||Starting Baseline||After 60min|
The Smartmi P1 is not a significant energy consumer. The device is powered by a 30W motor.
When I compare the motor’s power with similar devices, I can say that the Smartmi P1 is a much smaller consumer. However, this did not affect the strength of the airflow and the device’s performance; moreover, the P1 has an outstanding performance.
If you leave the Smartmi P1 running at max fan speed 24 hours a day for a month, your electricity bill will be increased by about $ 2.4. You can see how big an energy consumer the P1 is at all speeds in the table below.
|Speed||Power Usage (W)|
In addition to power consumption, P1 requires regular filter replacement. Fortunately, the filter on the P1 is lasting long, so you’ll need to change it on average between 6-12 months. All in all, running the Smartmi P1 is not a high cost when adding up the price of a replacement filter and electricity consumption for one year.

You can contact Smartmi in various ways. Whether you decide to contact them via the contact form, email, Facebook, or some other option, you will always receive an answer in record time.
I tested the support the same way I usually do, by measuring the speed and the answer quality. This time I sent an email and a message on Facebook. I am delighted with the speed of customer support and the quality of the response I received.
The contact email for Smartmi support is email@example.com.
You can also send them a message directly on Facebook or Twitter. My recommendation is to use Facebook if your answer is urgent or email if you need a comprehensive and exact solution.
The speed and efficiency of customer support and after-sale support is one of the most important things when it comes to buying any device. Smartmi passed this test with great success!
