Comparison: Levoit Core 200S vs 300S vs 400S – What are the Differences?

Coverage Area & Efficiency

With a coverage area of 17 m² (183 ft²) and 20 m² (219 ft²), respectively, the Core 200S and 300S are best suited for small rooms. The Core 400S, on the other hand, can be used in middle-sized rooms with a surface area of up to 37 m² (403 ft²).

According to Levoit, these recommendations are based on five air changes per hour (ACH) in a room with a ceiling height of 2.4 m (8 ft). While the air purifiers will still be effective in larger rooms, the purification process would simply take longer.

Clean Air Delivery Rate

In all three devices, a pre-filter captures large pollutants such as dust and pet fur. Next, an H13 True HEPA filter removes at least 99.97% of particles and allergens as small as 0.3 µm. Lastly, compounds including formaldehyde and VOCs are absorbed by activated carbon.

Thanks to Levoit’s ARC Formula, the Core 400S can also be used to deal with cooking smells and pet odors. It does all this at a rate of 442 m³/h (260 CFM), significantly faster than the Core 200S and Core 300S with a CADR of 200 m³/h (118 CFM) and 240 m³/h (141 CFM).

Working Noise

When set to sleep mode, the three air purifiers with their noise level of just 24 decibels (dB) are barely noticeable. Considering that the Core 400S is by far the most powerful, it is also impressive to see that the engineers at Levoit managed to cap its maximum noise at 52 dB.

The Core 200S and 300S come with three manual fan speed settings, while the Core 400S has an additional fourth one. The Core 300S and 400S can also be used in automatic mode, in which they only run as fast and therefore as loud as needed to maintain air quality.

Sensors & Display

Levoit’s AirSight Plus, a smart laser dust sensor, enables the Core 300S and 400S 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.

Indicator rings on the display of the Core 300S give you a rough idea of the current air quality, with blue signifying very good and red being unhealthy. The Core 400S allows you to see the exact amount of PM 2.5 particles on its display.

Conclusion: Levoit Core 200S vs 300S vs 400S – Which is the Best Air Purifier?

Both designed for small rooms and with a pretty similar CADR, the main difference between the Levoit Air Purifier Core 200S and its successor is the missing automatic mode. Now if you live in an area with constant pollution levels, this should not be too big of a problem.

But if the air quality in your room changes frequently, the Levoit Air Purifier Core 300S is the better choice. Adjusting the fan speed automatically, it makes sure that purified air is available throughout the room and helps you keep noise levels and energy consumption down.

Finally, if you have a middle-sized room or simply want the most powerful device of the three, the Levoit Air Purifier Core 400S is the best investment for you. Despite the high CADR, it is barely louder than 50 dB and comes with all features you would want in an air purifier.
