Breathing clean air at home is more important than ever. Many of us worry about dust, pet dander, and even invisible pollutants. Finding an air purifier that is both effective and fits our space can feel like a challenge. This is where the Xiaomi Air Purifier 4 Compact comes in. In this Xiaomi Air Purifier 4 Compact review, I’ll break down everything you need to know. We’ll see if this small but mighty device is truly a genius essential for your home’s air quality.
What is the Xiaomi Air Purifier 4 Compact?
The Xiaomi Air Purifier 4 Compact is a small, sleek device designed to clean the air in your living space. It uses a multi-layer filter system to capture tiny particles like dust, pollen, and smoke. Its compact size makes it perfect for smaller rooms like bedrooms or offices.
This air purifier aims to provide a simple solution for improving indoor air. It’s built to be user-friendly and connect with your smart home devices. The goal is to make breathing easier and your home healthier without much fuss.
Design and Build Quality
When I first saw the Xiaomi Air Purifier 4 Compact, I was struck by its minimalist design. It’s small, with clean lines, and comes in a neutral white color. This means it can blend into almost any room decor without being an eyesore.
The build quality feels solid for its price point. The plastic casing is smooth and doesn’t feel cheap. It’s designed to be unobtrusive, fitting easily on a desk, shelf, or bedside table.
Key Takeaway: Its compact and simple design makes it a great addition to any room without disrupting your style.
Performance and Air Purification
The real test for any air purifier is how well it cleans the air. The Xiaomi Air Purifier 4 Compact uses a powerful 3-in-1 filter. This filter includes a pre-filter, a HEPA filter, and an activated carbon filter.
This combination is designed to capture a wide range of pollutants. It tackles larger particles like hair and dust with the pre-filter. The HEPA filter grabs smaller things like pollen and mold spores. The activated carbon filter helps reduce odors from cooking or pets.
During my testing, I noticed a difference in the air quality within a few hours. The air felt fresher, and that lingering pet smell in my living room was significantly reduced. It’s surprisingly effective for its small size.
How effective is the Xiaomi Air Purifier 4 Compact?
The Xiaomi Air Purifier 4 Compact is quite effective for its size. It can purify a room of about 16-27 square meters (172-290 sq ft) quickly. Its CADR (Clean Air Delivery Rate) for particulate matter is around 200 m³/h, meaning it can clean the air in a room multiple times an hour.
This level of performance is excellent for bedrooms or small living areas. It helps reduce common allergens and odors, making your indoor environment more comfortable.
Filtration System Explained
Understanding the filter is key to appreciating how this device works. The Xiaomi Air Purifier 4 Compact uses a cylindrical filter that combines three layers. This design ensures efficient capture of different types of impurities.
First, the outer layer is a pre-filter. This catches larger particles like dust bunnies, pet hair, and lint. It helps protect the inner filters from getting clogged too quickly.
Next is the True HEPA filter. This is the workhorse for fine particles. It captures 99.97% of airborne particles as small as 0.3 microns. This includes things like pollen, mold spores, dust mites, and even some bacteria.
Finally, the activated carbon filter layer works to absorb odors and gases. It’s great for tackling smells from cooking, smoke, or pets. It also helps remove volatile organic compounds (VOCs) that can be present in household items.
Filter Lifespan and Replacement
Replacing the filter is a necessary part of owning an air purifier. Xiaomi recommends replacing the filter every 6 to 12 months, depending on usage and air quality. This is a pretty standard recommendation across many air purifiers.
The device will usually let you know when it’s time to change the filter. You can check the filter life percentage in the Mi Home app. Buying replacement filters is straightforward, and they are readily available online.
Smart Features and App Control
One of the standout features of Xiaomi products is their smart integration. The Air Purifier 4 Compact is no exception. It connects to your home Wi-Fi network and can be controlled via the Mi Home app.
The app is where you can really take control. You can turn the purifier on or off, adjust fan speeds, and set schedules. It also shows you real-time air quality data.
You can see the current PM2.5 levels in your room. The app also monitors the filter’s lifespan, reminding you when it’s time for a change. This smart functionality adds a lot of convenience.
Voice Control Integration
Beyond the app, the Xiaomi Air Purifier 4 Compact supports voice control. It works with popular voice assistants like Google Assistant and Amazon Alexa. This means you can control it just by speaking.
For example, you can say, “Hey Google, turn on the air purifier” or “Alexa, set the fan speed to medium.” This hands-free operation is incredibly convenient, especially when you’re busy or relaxing.
Noise Levels and Sleep Mode
For an air purifier, especially one used in a bedroom, noise level is a crucial factor. The Xiaomi Air Purifier 4 Compact is designed to be quiet. On its lowest setting, it operates at a very low noise level, often around 20 dB.
This is quieter than a whisper, so it shouldn’t disturb your sleep. The device also has a dedicated sleep mode. In this mode, the fan speed is reduced to its minimum, and the indicator lights are turned off.
This ensures that the air purifier works its magic without keeping you awake. I found it to be barely noticeable when running on its lowest setting overnight.
Ease of Use and Maintenance
Xiaomi products are known for their user-friendliness, and this air purifier is no different. Setting it up was very simple. You just take it out of the box, remove the filter packaging, and plug it in.
Connecting it to the Mi Home app took only a few minutes. The controls on the device itself are also straightforward. There’s a single button that you can tap or press and hold to change modes.
Maintenance primarily involves replacing the filter as needed. Cleaning the exterior is as simple as wiping it down with a soft cloth. The removable pre-filter can also be gently vacuumed if it gets dusty.
Pros and Cons
Like any product, the Xiaomi Air Purifier 4 Compact has its strengths and weaknesses. Here’s a quick rundown to help you weigh your options.

Pricing and Value
The Xiaomi Air Purifier 4 Compact is positioned as an affordable option. Its price point makes it accessible to many people looking for basic air purification. When you consider its features, performance, and smart capabilities, it offers excellent value for money.
Compared to larger, more expensive models, it might not cover huge spaces. However, for its intended use in smaller rooms, it delivers a lot for what it costs. The ongoing cost of replacement filters should be factored in, but they are reasonably priced.
Competitor Analysis
When looking at similar products, the Xiaomi Air Purifier 4 Compact holds its own. Many other brands offer compact air purifiers, but they often lack the smart features or the robust filtration system at this price.
For instance, some basic models might only have a single-layer filter or no app connectivity at all. Others might be quieter but less effective at particle removal. The Levoit Core 300 is a popular competitor, offering similar filtration but often at a slightly higher price and without the same level of smart home integration. Coway’s compact models are also strong contenders, known for their quietness and effective filtration, but again, usually come with a premium price tag.
The key differentiator for the Xiaomi Air Purifier 4 Compact is its balance of performance, smart features, and affordability. It truly stands out as a “genius essential” for those on a budget or with smaller spaces.
