Exploring the Capabilities of the Xiaomi Mijia Air Purifier 5S

The Xiaomi Mijia Air Purifier 5S is a recent addition to Xiaomi's lineup of smart home devices, focusing on providing comprehensive indoor air purification. It is designed to tackle a range of airborne pollutants, from common dust and allergens to more harmful volatile organic compounds (TVOCs) and formaldehyde. This model aims to deliver enhanced purification performance within the Mijia smart home ecosystem.

Key Highlights of the Mijia Air Purifier 5S

Enhanced Formaldehyde and TVOC Removal: The 5S model places a significant emphasis on removing harmful chemical pollutants like formaldehyde and TVOCs, with claimed high removal rates within a short period.
Comprehensive Filtration System: It incorporates a multi-layer filtration system, including a HEPA filter and activated carbon, to effectively capture a wide range of airborne particles and odors.
Smart Features and App Control: The purifier integrates with the Mijia app, allowing for remote control, monitoring of air quality data, and potentially integration with other Xiaomi smart home devices.

Detailed Features and Performance

Advanced Filtration for Diverse Pollutants

The Mijia Air Purifier 5S utilizes a multi-stage filtration process to ensure cleaner air. This typically includes a primary filter to capture larger particles like dust and hair, followed by a high-efficiency filter (often a HEPA-type filter) to trap smaller particles such as PM2.5, pollen, and pet dander. A key component is the activated carbon filter, which is specifically designed to adsorb harmful gases and odors, including formaldehyde and TVOCs. The integration of these filters allows the 5S to address a broad spectrum of indoor air quality concerns.

Focus on Formaldehyde and TVOCs

A notable feature of the 5S is its focus on volatile pollutants. Sources indicate a formaldehyde Clean Air Delivery Rate (CADR) of 255 m³/h, with claims of being able to remove a significant percentage of formaldehyde within one hour. This is particularly relevant for new or renovated homes where off-gassing from furniture and building materials can be a concern. The purifier is also stated to remove a high percentage of TVOCs, which are emitted from various household products and can contribute to poor indoor air quality.

Purification Capacity and Coverage Area

The effectiveness of an air purifier is often measured by its CADR, which indicates how quickly it can remove pollutants from a room. While specific particle CADR figures for the 5S are available, they suggest it is suitable for a decent coverage area. For example, some sources mention application areas ranging from 36 to 62 square meters, although it's important to note that actual performance can vary depending on factors like room layout and the level of pollution. The Mijia Air Purifier 5 Pro, a related model, boasts a higher particle CADR of 1050 m³/h and covers larger areas, providing a point of comparison within the Xiaomi range.

Smart Connectivity and User Experience

As part of the Mijia ecosystem, the 5S offers smart connectivity through the Mi Home/Xiaomi Home app. This allows users to control the purifier remotely, monitor real-time air quality data (including formaldehyde concentration), and adjust settings like fan speed and operating modes. The app integration enhances user convenience and provides valuable insights into indoor air conditions. The device also features a digital display, likely OLED, to show key information directly on the unit.

First look and review of the Xiaomi Mijia Air Purifier 5S.

Design and Aesthetics

Xiaomi air purifiers are generally known for their minimalist and clean design, and the 5S appears to follow this trend. The pure white tones and clean lines allow it to blend into various home environments. The physical dimensions are provided in some listings, giving an idea of its footprint.

Noise Levels

Noise level is an important consideration for air purifiers, especially for use in bedrooms. While specific noise figures for all operating modes of the 5S might not be readily available, some sources mention operation under 31 dB, likely in a low or sleep mode. It's worth noting that higher fan speeds for faster purification will generally result in increased noise.

Comparing the Mijia Air Purifier 5S with other Models

Xiaomi offers a range of air purifiers, each with varying specifications and features. The 5S appears to be positioned as a model with enhanced capabilities for removing chemical pollutants compared to some earlier or more basic models. The Mijia Air Purifier 5 Pro, with its significantly higher particle CADR, is positioned for larger spaces or situations requiring more rapid particle removal. The Xiaomi Smart Air Purifier 4 Lite, for instance, has a CADR of 360 m³/h, indicating it's suitable for smaller areas than the 5S's stated coverage.

Key Specifications Comparison (Illustrative)

Formaldehyde CADR	255 m³/h	424 CFM (approx. 720 m³/h)	150 m³/h
Particle CADR	N/A (Specific number not consistently provided in sources for 5S, but implied lower than 5 Pro)	1050 m³/h (618 CFM)	360 m³/h (212 CFM)
Coverage Area	36-62㎡	56-96 m²	~20-40 m²
Formaldehyde Removal Rate (1 hour)	96.95%	N/A	High efficiency
TVOC Removal Rate	98.1%	N/A	N/A
Smart Connectivity	Yes (Mijia App)	Yes (MiHome)	Yes (Mi Home/Xiaomi Home App)

This table provides a comparative overview based on information from the provided sources. Note that specific CADR figures and coverage areas can sometimes vary slightly depending on the testing standards and source.

User Experience and App Integration

The integration with the Mi Home/Xiaomi Home app is a significant aspect of the user experience. The app allows for convenient control and monitoring, enabling users to check air quality levels remotely, set schedules, and receive notifications regarding filter life. The app also facilitates connectivity with other Xiaomi smart home devices, potentially allowing for automated scenarios based on air quality. Users have generally found the app to be user-friendly for controlling Xiaomi air purifiers.

Maintenance and Filter Replacement

Maintaining an air purifier typically involves cleaning the pre-filter and replacing the main filter periodically. Xiaomi air purifiers provide indicators or notifications through the app when the filter needs replacement. The frequency of filter replacement depends on usage and the level of pollutants in the environment, but a lifespan of 6-12 months is often suggested for the main filter in some models.

Maintaining Optimal Performance

Regular cleaning of the air inlets and fan blades is also recommended to prevent reduced air intake and maintain purification efficiency. User manuals for Xiaomi air purifiers provide detailed instructions on cleaning and maintenance procedures.
