Comparison: Levoit Core 400S vs 600S – What are the Differences?

Coverage Area & Efficiency

Levoit recommends the Core 400S for middle-sized rooms with a surface area of up to 37 m² (403 ft²). The more powerful 600S can be used in even larger rooms and comes with an effective range of up to 59 m² (635 ft²).

For both models, the numbers are based on an assumed five air changes per hour (ACH) in a room with a ceiling height of 2.4 m (8 ft). While they could be used to cover bigger areas, the amount of ACH would decrease accordingly.

Clean Air Delivery Rate

Levoit’s 3-stage filtration system utilizes a pre-filter to remove large pollutants including dust, hair, and pet fur. Next, an H13 True HEPA filter captures at least 99.97% of particles and allergens as small as 0.3 µm, for example, pollen and pet dander.

Lastly, smoke, fumes, VOCs, and household odors such as cooking smells and pet odors are neutralized by a layer of activated carbon. The Core 400S does this at a rate of 442 m³/h (260 CFM), while the 600S comes with a Clean Air Delivery Rate (CADR) of 697 m³/h (410 CFM).

Working Noise

Running at full speed, the Core 400S operates at a noise level of around 52 decibels (dB) and is thus slightly less noisy than the 600S at 55 dB. The difference becomes even smaller on the lower end, with 24 dB for the 400S compared to 26 dB for its successor.

Both models can be set to automatic mode, in which they will run only as fast and therefore as loud as needed to maintain healthy air quality. Once pollution levels start dropping back to normal after a sudden spike, their fan speed and noise level will decrease accordingly.

Sensors & Display

Levoit’s AirSight Plus, a smart laser dust sensor, enables the Core 400S and 600S to track the surrounding air quality in real-time. In automatic mode, this information is then used to increase or decrease the fan speed according to the pollution levels (see above).

Indicator rings on the display of both models give you a rough idea of the current air quality, with blue signifying very good and red being unhealthy. The exact level of PM 2.5 particles in the air is also shown on the display, as well as the VeSync app (see below).

Connectivity & Compatibility

You can use a Wi-Fi connection, your smartphone, and the VeSync app to monitor and control both the Core 400S and 600S remotely. This allows you to turn the purifier on and off, create a schedule, view the remaining filter life, and more.

In addition, all models of the Core S series, which includes the 400S and 600S, support voice control via Amazon Alexa and Google Assistant and can thus be seemingly integrated with your smart home.

Weight & Dimensions

In the final round of this Levoit Core 400S vs 600S comparison, we will have a quick look at the weight and dimensions of the two air purifiers. At 6.2 kg (13.7 lb) and 313 x 313 x 600 mm (12.3 x 12.3 x 23.6 in), the Core 600S is both heavier and larger than its competitor.

Conclusion: Levoit Core 400S vs 600S – Which is the Better Air Purifier?

As expected, the Levoit Air Purifier Core 600S had the upper hand in this comparison. It can be used in significantly larger areas and comes with the highest CADR among all the brand’s models, all the while operating at an almost similarly low noise level to its predecessor.

That said, if you are only looking to purify a medium-sized room, opt for the Levoit Air Purifier Core 400S instead. It, too, comes with all the features you would want in a modern air purifier, and at the same time requires a smaller investment than the newer high-end model.
