Xiaomi has been a leader in providing affordable yet high-quality technology, and their air purifiers are no exception. Their latest 4 series builds upon the success of previous models, simplifying naming conventions and enhancing functionality. As an owner of the Xiaomi Mi Air Purifier 3H, I can personally vouch for its effectiveness in improving air quality in my home, alleviating my asthma symptoms, and removing pesky soldering odours from my workspace.

Introducing the Xiaomi Smart Air Purifier 4 Line-up
The new Xiaomi Smart Air Purifier 4 line-up consists of three models tailored to different needs and budgets:
- Xiaomi Smart Air Purifier 4: A worthy successor to the popular Mi Air Purifier 3H, this model provides improved functionality.
- Xiaomi Smart Air Purifier 4 Lite: A budget-friendly option, delivering core features in a simplified design.
- Xiaomi Smart Air Purifier 4 Pro: For larger spaces, this model offers high performance for expansive areas.
Xiaomi Smart Air Purifier 4: Bigger, Better, and Fresher
The Xiaomi Smart Air Purifier 4 is slightly larger than its predecessor, with dimensions of 250 × 250 × 520 mm. It boasts a 5% increase in Clean Air Delivery Rate (CADR) to 400 m³/h while consuming 20% less energy and producing less noise.
A standout feature of this model is its Negative Air Ion (NAI) generator. While the science on NAIs remains inconclusive, they have been shown to remove particulate matter effectively. Additionally, a new filter design with a thicker layer of activated carbon and Xiaomi’s proprietary High-Efficiency Filter enhances airflow, contributing to quieter and more efficient operation.
While not exactly repair-friendly, the Xiaomi Smart Air Purifier 4 is at least easy to clean. The fan grill on top can be removed without fumbling with tabs or screws, making the device's insides accessible for maintenance.
The Xiaomi Smart Air Purifier 4 is available in the Swiss Xiaomi store from March, priced at CHF199 (~US$220) including taxes.
Xiaomi Smart Air Purifier 4 Lite: Compact and Affordable
Standing a centimetre taller than the Mi Air Purifier 3H, the 4 Lite offers a lower CADR of 360 m³/h and omits the negative ion generator. The new filter model is accessible via the top compartment. The design leans toward a boxy shape with rounded edges, featuring a basic seven-segment display, reminiscent of an alarm clock, and capacitive buttons.
The Xiaomi Smart Air Purifier 4 Lite is available in the Swiss Xiaomi store from March, priced at CHF169 (~US$183) including taxes.
Xiaomi Smart Air Purifier 4 Pro: Power for Large Spaces
The Xiaomi Smart Air Purifier 4 Pro, with dimensions of 275 × 275 × 680 mm, is designed to purify spaces up to 60㎡, offering a CADR of 400 m³/h. It shares the negative ion generator and design of the base model, delivering improved efficiency and quieter operation.
The Xiaomi Smart Air Purifier 4 Pro is available in the Swiss Xiaomi store for CHF299 (~US$325) including taxes.
Conclusion: Is the Upgrade Worth It?
If you’re considering upgrading, the decision hinges on two factors: the NAI generator and quieter operation. If these are priorities for you, the 4 series is an excellent option. However, if your current air purifier meets your needs, it may be worth holding on to it for now.
