If you’re considering the Xiaomi Smart Air Purifier 4 Compact, it’s important to weigh its strengths and weaknesses before making a decision. This compact air purifier is packed with features that make it a great choice for small spaces, but it also has a few limitations worth noting. Let’s break down the pros and cons in detail so you can determine if it’s the right fit for your needs.

Pros

1. Outstanding Air Purification

The Xiaomi Smart Air Purifier 4 Compact truly shines when it comes to cleaning the air. During testing, it achieved impressive results, reducing PM2.5 levels to 0.1 and PM10 levels to 0.2 within an hour. These numbers are significantly better than the average performance of similar devices on the market. If you’re looking for a purifier that can effectively tackle pollutants like dust, allergens, and pet dander, this device won’t disappoint.

2. Whisper-Quiet Operation

One of the standout features of this purifier is how quiet it is. Even at its highest setting, the noise level stays below 42.8 dB, which is quieter than most household appliances. In sleep mode, it operates at just 20 dB, making it barely noticeable. This makes it an excellent choice for bedrooms, offices, or any space where silence is key.

3. Compact and Lightweight Design

As the name suggests, this air purifier is designed to be both compact and lightweight. With dimensions of just 220 x 220 x 355 mm and a weight of 2.2 kg (4.8 lbs), it’s incredibly easy to move around. Whether you need it in your living room, bedroom, or even a dorm, its portability ensures it fits seamlessly into your lifestyle.

4. Smart Features for Convenience

The Xiaomi Smart Air Purifier 4 Compact is equipped with modern smart features that enhance usability. You can connect it to the Mi Home/Xiaomi Home app to monitor real-time air quality, adjust settings, and schedule operations. It’s also compatible with Google Assistant and Amazon Alexa , allowing you to control it with simple voice commands. These features make it a great option for tech-savvy users who value convenience.

5. Energy Efficiency

This purifier is designed to consume minimal power while still delivering high performance. Its energy-efficient design not only helps reduce your electricity bills but also makes it an eco-friendly choice. You can enjoy clean air without worrying about excessive energy consumption.

6. Additional Safety and Comfort Features

For families, the inclusion of a child lock and sleep mode adds an extra layer of safety and usability. The child lock prevents accidental changes to settings, while sleep mode ensures quiet and uninterrupted operation during the night.

Cons

1. Limited Coverage Area

While the Xiaomi Smart Air Purifier 4 Compact performs exceptionally well, it’s best suited for small rooms up to 158 sq. ft. If you’re looking for a device to purify the air in larger spaces like living rooms or open-plan areas, this purifier may not meet your needs. Its coverage area is one of its main limitations.

2. Dependence on the App for Advanced Controls

Although the companion app offers useful features, some users might find it inconvenient that most advanced controls—like manual settings and detailed air quality monitoring—are accessible only through the app. If you prefer physical buttons or don’t want to rely on your smartphone, this could be a drawback.

3. Slightly Higher Post-Test AQI Reading

While the purifier excels in reducing pollutants, some tests have shown that its AQI reading post-purification was slightly higher than average compared to other purifiers in its category. While this doesn’t necessarily mean the air isn’t clean, it’s something to keep in mind if you’re particularly sensitive to air quality metrics.

How to Set Up the Xiaomi Air Purifier 4 Compact

Setting up your new Xiaomi Air Purifier 4 Compact is a straightforward process, but following the steps carefully will ensure you get the most out of this powerful little device. Whether you’re using it in your bedroom, office, or dorm, proper setup ensures optimal performance and convenience. Let’s walk through the process step by step.

Setting Up the Device

1. Unboxing and Initial Setup

When you first unbox your Xiaomi Air Purifier 4 Compact, you’ll find the following items inside:

The air purifier itself
A power adapter
A user manual

Before you start, take a moment to inspect the contents to ensure everything is included. Next, locate the filter compartment at the bottom of the purifier. Carefully remove the filter and unwrap it from its protective plastic packaging. Once unwrapped, reinsert the filter securely into the compartment. This step is crucial because the filter won’t function properly if left in its packaging.

2. Powering On

Once the filter is in place, plug the power adapter into the purifier and connect it to a power outlet. Press the power button to turn on the device. You should see the indicator light come on, signalling that the purifier is ready to use.

Connecting to Wi-Fi

To take full advantage of the smart features, you’ll need to connect your Xiaomi Air Purifier 4 Compact to your home Wi-Fi network. Here’s how:

Download the Mi Home/Xiaomi Home App:
You can download the app by scanning the QR code provided in the user manual or searching for “Mi Home” or “Xiaomi Home” in your smartphone’s app store.
Add the Device:
Open the app and tap the “+” icon to add a new device. Follow the on-screen instructions to connect your purifier. Make sure your phone is connected to a 2.4 GHz Wi-Fi network , as the device is not compatible with 5 GHz networks.
Troubleshooting Connection Issues:
If you encounter any problems during setup or need to reset the Wi-Fi connection, press and hold the light adjustment button for 7 seconds. This will reset the Wi-Fi settings, allowing you to reconnect.

Mode Selection

The Xiaomi Air Purifier 4 Compact offers multiple operating modes to suit your needs. You can switch between these modes using the mode switch button located on the control panel:

Auto Mode: In this mode, the purifier automatically adjusts its fan speed based on the air quality in your room. It’s perfect for hands-free operation.
Sleep Mode: This mode minimizes noise and reduces energy consumption, making it ideal for nighttime use.
Manual Mode: Allows you to adjust the fan speed to your preference manually.

Child Lock Feature

If you have children or pets at home, the child lock feature is a great way to prevent accidental changes to the purifier’s settings. To enable or disable the child lock, press and hold the mode switch button for 7 seconds. You’ll see an indicator light confirming that the child lock is active.

Maintenance Tips for the Xiaomi Air Purifier 4 Compact

Regular maintenance is essential to keep your Xiaomi Air Purifier 4 Compact running smoothly and ensure it continues to deliver clean, fresh air. Proper care not only extends the life of the device but also ensures optimal performance. Here’s a step-by-step guide to help you maintain your air purifier effectively.

Filter Replacement

The filter is the heart of your air purifier, and replacing it on time is crucial for maintaining air quality. Here’s what you need to know:

When to Replace: Depending on usage and the air quality in your space, you should replace the filter every 6–12 months. If you live in an area with high pollution or have pets, you might need to replace it more frequently.
How to Replace:
1. Start by unplugging the device to ensure safety.
2. Turn the purifier upside down and locate the filter compartment at the bottom. Unscrew it to access the filter.
3. Remove the old filter and dispose of it properly. Before inserting the new filter, use a vacuum to clean out any dust or debris inside the compartment.
4. Insert the new filter securely and screw the compartment back into place.
Resetting the Filter Indicator: After replacing the filter, reset the filter indicator by holding the power button for 6 seconds while the device is in standby mode. This will clear the notification and ensure accurate tracking of the new filter’s lifespan.

Cleaning the Device

Keeping the exterior and internal components clean is just as important as replacing the filter. Here’s how you can do it:

Exterior Cleaning: Use a dry, soft cloth to wipe down the exterior of the purifier regularly. Avoid using water or cleaning agents, as they could damage the surface.
Sensor Maintenance: The particulate matter sensor plays a key role in monitoring air quality. Over time, dust can accumulate around the sensor, affecting its accuracy. To prevent this, use a vacuum or a soft brush to clean the area around the sensor gently. This simple step ensures that your purifier provides reliable air quality readings.

Monitoring the Filter Exhaustion Indicator

Your Xiaomi Air Purifier 4 Compact makes it easy to stay on top of filter maintenance. The device features a filter exhaustion indicator that alerts you when it’s time to replace the filter.

You can check this directly on the purifier’s display or through the Mi Home/Xiaomi Home app. Keeping an eye on this indicator helps you avoid unnecessary wear and tear on the device and ensures consistent performance.

Using the App for Maintenance

The Mi Home/Xiaomi Home app is a powerful tool for managing your air purifier remotely. Here’s how it can simplify maintenance:

Air Quality Monitoring: The app provides real-time updates on air quality, allowing you to track improvements and make adjustments as needed.
Settings and Scheduling: You can adjust fan speeds, switch between modes (Auto, Sleep, Manual), and set schedules to optimize energy efficiency.
Filter Life Tracking: The app also monitors the remaining life of your filter, sending you reminders when it’s time for a replacement. This feature ensures you never miss a filter change, keeping your air purifier in top condition.

Why Regular Maintenance Matters

Taking care of your Xiaomi Air Purifier 4 Compact isn’t just about extending its lifespan—it’s about ensuring it continues to provide you with clean, healthy air. By replacing filters on time, keeping the device clean, and leveraging the smart features of the Mi Home app, you can enjoy peace of mind knowing your air purifier is working efficiently.
