This Xiaomi Smart Air Purifier 4 review confirms it’s an essential device for cleaner indoor air, effectively tackling pollutants with smart features and strong performance. It offers a practical solution for healthier living spaces, making it a worthwhile investment for many homes.
Breathing clean air at home is important for everyone’s health. Many homes have air that isn’t as fresh as it should be. Dust, pollen, pet dander, and even tiny particles from cooking can fill your rooms. This can cause allergies, breathing problems, and make you feel tired. You might be wondering if there’s a simple way to make your home’s air much better. This Xiaomi Smart Air Purifier 4 review will show you how this device can help. We will look at its features, how well it works, and if it’s the right choice for your clean air needs.
Why Clean Air Matters Indoors
Indoor air can be up to five times more polluted than outdoor air. This is surprising, but true. Things like cleaning products, furniture, and even cooking can release harmful particles into your home. Breathing these can lead to sneezing, coughing, and long-term health issues. Children and people with asthma are especially sensitive to poor air quality. Making your indoor air clean is a key step to a healthier life for your family.
The Problem of Indoor Air Pollution
Common household activities release unseen pollutants. Cooking creates fine particles that linger in the air. Pets shed dander, which can trigger allergies for many people. Dust mites and mold spores can also thrive indoors, impacting respiratory health. Even opening windows might not always help if outdoor air quality is poor. Understanding these sources helps us see why air purifiers are becoming so popular.
Unpacking the Xiaomi Smart Air Purifier 4: What’s Inside?
The Xiaomi Smart Air Purifier 4 is designed to be a user-friendly and effective solution. It uses a multi-stage filtration system to capture a wide range of airborne contaminants. This includes a pre-filter, a true HEPA filter, and an activated carbon filter. Together, these layers work to remove particles, allergens, odors, and gases. It’s built to handle medium to large rooms, making it versatile for many homes.
Key Features of the Xiaomi Smart Air Purifier 4
This air purifier boasts several smart features. You can control it using the Mi Home app on your smartphone. This allows you to adjust settings, check filter life, and monitor air quality from anywhere. It also works with voice assistants like Google Assistant and Amazon Alexa. The device has an auto mode that adjusts fan speed based on real-time air quality readings. Its sleek design also helps it blend into most home decors.
Design and Build Quality: A Modern Look
Xiaomi products are known for their clean and minimalist designs. The Smart Air Purifier 4 is no exception. It has a simple, cylindrical shape with a smooth white finish. The top of the unit features an air outlet grille. The front has a discreet display that shows important information. Its compact size means it won’t take up too much floor space.
Portability and Placement
The air purifier is lightweight enough to move between rooms if needed. It has a stable base that prevents it from tipping over easily. For best results, it should be placed in an open area away from walls or furniture that might block airflow. This ensures it can effectively circulate air throughout the room. Placing it in the room where you spend the most time, like the living room or bedroom, is often recommended.
Understanding the Filtration System: How it Cleans Air
The heart of any air purifier is its filter. The Xiaomi Smart Air Purifier 4 uses a 3-in-1 filter. This filter combines three layers to tackle different types of pollution. The first layer is a basic mesh filter. It catches large particles like hair and dust. The second is the true HEPA filter. This is crucial for trapping smaller particles like pollen and pet dander. The third layer is an activated carbon filter. It absorbs odors from cooking, pets, and smoke.
HEPA Filter Efficiency Explained
True HEPA filters are certified to remove at least 99.97% of airborne particles that are 0.3 microns in size. This is a very small size. Particles this small include bacteria, viruses, and fine dust. This high efficiency means the filter is very good at cleaning the air you breathe. The Xiaomi Smart Air Purifier 4 uses such a filter to ensure maximum particle removal.
Performance: Does it Actually Work?
In real-world testing, the Xiaomi Smart Air Purifier 4 performs well. It quickly reduces the level of common indoor pollutants. Users often report a noticeable difference in air freshness within hours of using it. Its powerful fan can circulate air in a medium-sized room multiple times per hour. This ensures that polluted air is constantly being drawn in and cleaned.
Noise Levels: Quiet Operation
One important factor for air purifiers is noise. The Xiaomi Smart Air Purifier 4 is designed for quiet operation, especially on its lower fan settings. On its quietest mode, it produces around 32 decibels of sound. This is quieter than a whisper. Even on higher settings, the noise is generally not disruptive. This makes it suitable for use in bedrooms or offices.
Smart Features and App Control: Convenience at Your Fingertips
The smart capabilities of the Xiaomi Smart Air Purifier 4 add significant value. The Mi Home app provides a detailed look at your indoor air quality. It shows PM2.5 levels, temperature, and humidity. You can set schedules for the purifier to turn on or off. You can also create custom modes based on your needs. This level of control makes managing your home’s air quality effortless.
Voice Control Integration
For added convenience, the purifier works with popular voice assistants. You can simply ask Google Assistant or Alexa to turn the purifier on or off. You can also ask it to change fan speeds. This hands-free operation is perfect when you’re busy or have your hands full. It integrates smoothly into a smart home ecosystem.
Filter Lifespan and Replacement: Keeping it Running
The filters in the Xiaomi Smart Air Purifier 4 are designed to last. Depending on usage and air quality, a filter typically needs replacement every 6 to 12 months. The Mi Home app will notify you when the filter is nearing the end of its life. Replacing the filter is a simple process. You just open the cover, remove the old filter, and insert the new one.
Cost of Replacement Filters
Replacement filters are an ongoing cost to consider. Xiaomi offers genuine replacement filters for the Smart Air Purifier 4. While the initial purchase price of the purifier is competitive, factor in the cost of replacement filters. This ensures you maintain the purifier’s effectiveness over time. You can often find deals on filter packs.
Comparing the Xiaomi Smart Air Purifier 4 to Competitors
The Xiaomi Smart Air Purifier 4 stands out in its price range. Many competitors offer similar features but at a higher cost. For example, brands like Coway or Blueair often have models with comparable HEPA filtration and smart features, but they can be significantly more expensive. Levoit is another popular brand that offers good value, but Xiaomi often leads in integrated smart home connectivity.

Its integration with the Mi Home ecosystem is seamless, which is a big plus for existing Xiaomi users.
