Test result preview
The Levoit Core 400S is a powerful and intelligent air purifier that has been specially developed for large rooms. With a coverage of up to approx. 184 m², it is ideal for living, sleeping or working areas. Thanks to the advanced AirSight Plus technology, the device scans the air quality in real time and automatically adjusts the fan speed to ensure optimum filtration performance. The 3-in-1 HEPA filter system removes up to 99.97% of particles such as dust, pollen, smoke and odours, thus ensuring a healthy indoor climate. The sleep mode is particularly practical, ensuring an undisturbed night’s sleep with a noise level of just 24 dB. Operation via the intuitive VeSync app or voice assistants such as Alexa and Google Assistant also emphasises the user-friendliness. One negative aspect, however, is that the replacement filters are only available from the manufacturer. The Levoit Core 400S offers a successful combination of efficiency, modern technology and appealing design that fulfils even the highest demands.
Advantages
- Cleans large rooms effectively
- Intelligent control via app and voice assistant
- Quiet operation in sleep mode
Disadvantages
- Replacement filters only available from the manufacturer

The Levoit Core 400S air purifier leaves a thoroughly positive first impression when unpacked. The device is delivered in sturdy packaging that is adapted to the product size and effectively protects the product from damage during transport. It is particularly positive that no superfluous packaging material has been used. Nevertheless, plastic film is sometimes used, for example for the filter, which slightly impairs the sustainability of the packaging.
The scope of delivery includes the air purifier with a pre-installed 3-in-1 HEPA filter as well as a detailed and clearly worded instruction manual that makes it easy to set up. All components are securely stowed away so that the air purifier arrives at the customer’s premises undamaged and free from scratches or dirt.
Overall, the packaging impresses with its functional protection and clear structuring of the contents. There is only room for improvement in a greater reduction of plastic materials in order to increase environmental friendliness. The entire unpacking experience emphasises the high quality standards of the Levoit brand and immediately gives the user the feeling of holding a high-quality product in their hands.

As part of our practical test, the Levoit Core 400S was thoroughly tested under various aspects. The volume measurements revealed excellent values: In sleep mode, the noise level is just 24 dB, which is barely audible and ideal for use in bedrooms. At higher power levels, the air purifier logically becomes significantly louder.
The air purifier showed impressive results in the odour neutralisation test. Within an hour, it was able to almost completely remove unpleasant odours such as smoke, and the subjective assessment by test persons confirmed its effectiveness. Room coverage was also tested. Here, the device was able to efficiently supply a room of approx. 180 m² with clean air and showed uniform air quality at various measuring points.
The operation and user-friendliness of the Core 400S proved to be intuitive. The VeSync app enables simple control, while the connection to the Wi-Fi remained stable and reliable. All functions, including auto mode and sleep mode, responded quickly and flawlessly. Overall, the Levoit Core 400S fulfils its advertising promises and proves to be a powerful air purifier for large rooms.
