With the launch of the Xiaomi Smart Air Purifier 4 series in India, Xiaomi has introduced an affordable yet feature-rich solution to address the growing concern of indoor air pollution. Intrigued by its impressive specifications, I couldn’t resist getting my hands on the Xiaomi Smart Air Purifier 4 to test its capabilities. In today’s fast-paced world, where pollution levels are on the rise, ensuring clean and fresh indoor air has become a top priority for many households. The Xiaomi Smart Air Purifier 4 promises to deliver on this front by offering an effective solution to combat indoor air pollution and create a healthier living environment.

In this in-depth review, we will delve into various aspects of the Xiaomi Smart Air Purifier 4, including its packaging, design, features, performance, smart connectivity, and overall user experience. So, let’s dive into the details and see if the Xiaomi Smart Air Purifier 4 lives up to its claims.

Packaging and Setup:

The Xiaomi Smart Air Purifier 4 arrives in a well-designed package, ensuring the unit’s safety during transportation. Inside the package, you will find the air purifier, a power cable, and an instruction manual. The setup process is straightforward and requires minimal effort.

To get started, simply unwrap the plastic packaging of the HEPA filter and carefully place it inside the air purifier. Once the filter is securely in place, simply plug in the power cable, turn on the purifier, and you’re ready to enjoy cleaner air.

Design and Build Quality:

The Xiaomi Smart Air Purifier 4 is a stylish and modern device that seamlessly integrates into any home decor. It retains the rectangular cuboid shape of its predecessor, the Xiaomi Smart Air Purifier 3, but comes with curved corners that enhance its elegance. The minimalist design is complemented by a matte white finish, although it may require occasional cleaning to maintain its pristine appearance.

At the top of the purifier, there is a fan protected by a sturdy grille. This design allows for efficient airflow without obstructions, ensuring effective air filtration. The grille is securely lined to prevent accidental finger insertion, prioritizing safety, especially for households with children. A switch with the Xiaomi logo is located at the top, in the center of the grille mount. This allows easy access for cleaning the fan and maintaining optimal performance.

The front of the purifier features a circular OLED panel with touch capabilities, providing an intuitive interface. The sides of the purifier have a perforated grille design, maximizing air intake for efficient filtration. At the back of the purifier, a laser sensor detects particulate matter (PM) particles. The sensor, along with a hard reset button, is conveniently located for easy access. Opening the rear panel provides access to the filter module, which includes a new True HEPA filter.

Xiaomi Smart Air Purifier 4 Features:

The Xiaomi Smart Air Purifier 4 comes packed with several features that enhance its functionality. The purifier utilizes a 3-in-1 filtration system, consisting of a pre-filter, a high-efficiency filter, and an activated carbon filter. This combination effectively captures dust, allergens, pet dander, smoke, and odors, ensuring cleaner and fresher air. The pre-filter is responsible for trapping larger particles, while the high-efficiency filter targets microscopic pollutants as small as 0.3 microns. The activated carbon filter efficiently tackles harmful gases and unpleasant odors, leaving the air smelling fresh and rejuvenated.

The Xiaomi Smart Air Purifier 4 features a 360-degree air intake system, allowing it to draw in pollutants from all directions. This design maximizes air purification efficiency and ensures that every corner of the room is covered.

The touch-sensitive panel allows for easy control and navigation, enabling users to switch between different modes and adjust settings with a simple touch. The OLED display shows real-time information on the air quality index (AQI) levels, providing immediate insights into the cleanliness of the air. Additionally, a smaller row displays the ambient temperature, humidity level, and the currently selected mode. An LED light bar beneath the display changes colors to reflect the current air quality status, allowing users to determine the air quality at a glance.

Furthermore, I appreciate the safety feature where if you happen to open the back panel to access the filter while the purifier is running, it will automatically turn off to prevent any accidental mishaps.

Performance:

When it comes to performance, the Xiaomi Smart Air Purifier 4 excels. It employs a powerful fan and advanced filtration technology to quickly and effectively remove airborne pollutants. The combination of the pre-filter, high-efficiency filter, and activated carbon filter ensures that a wide range of pollutants are captured and eliminated from the air. This is especially important in areas with high levels of air pollution, where the purifier can make a noticeable difference in the air quality. With its high Clean Air Delivery Rate (CADR) of 400 m3/h, the Xiaomi Smart Air Purifier 4 is capable of purifying the air in medium to large-sized rooms.

In my personal experience, I live in a city where the air quality is generally good. Now it’s monsoon so the AQI is even better. But so far I have noticed that the purifier was able to make a noticeable difference, even when the air was already clean. When the AQI was around 200, the purifier was able to bring it below 30 within just 15-20 minutes, despite being in its lowest setting. I also observed that it effectively eliminated cooking and other odors in a short amount of time. It’s worth noting that at its lowest settings, the fan noise is barely audible, but at the highest settings, it can be quite loud, especially when sleeping. Therefore, I recommend keeping the settings low or medium while sleeping for a quieter experience.

Smart Connectivity:

The Xiaomi Smart Air Purifier 4 offers seamless smart connectivity, allowing you to control and monitor the device remotely. By connecting the purifier to the Mi Home app, available for both Android and iOS devices, you gain access to a range of convenient features.

Setting up the Xiaomi Smart Air Purifier 4 is a breeze. Once you have installed the Xiaomi Home app and followed the on-screen instructions, you can easily add the purifier to your system. The app provides a user-friendly interface where you can access various controls and settings. You can toggle the ionizer, adjust the fan speed, and monitor real-time statistics and parameters. The app also offers voice control compatibility with Google Assistant and Amazon Alexa, allowing you to operate the purifier using voice commands.

Final Verdict:

In conclusion, the Xiaomi Smart Air Purifier 4 offers an excellent balance of design, performance, and smart features. Its ability to efficiently purify the air and provide real-time air quality monitoring makes it a valuable addition to any home. Priced competitively at Rs 14,999, it is a worthwhile choice for small to medium-sized rooms. Highly recommended for creating a healthier living environment.
