Comparison: Levoit Core 300 vs 300S – What are the Differences?
Coverage Area & Efficiency
With a coverage area of up to 20 m² (219 ft²) each, the Core 300 and Core 300S are suitable for bedrooms, home offices, and other relatively small rooms. Both are equipped with Levoit’s VortexAir technology, which allows them to distribute clean air evenly throughout the room.
According to the brand, the recommended coverage area is 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
Both devices utilize a 3-stage filtration system beginning with a pre-filter for 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.
In the final step, smoke, fumes, VOCs, and household odors such as cooking smells and pet odors are neutralized by a layer of activated carbon. The Core 300 and Core 300S do all this at a rate of 240 m³/h (141 CFM).

Working Noise
At just 24 decibels (dB), you will barely notice the Core 300 and Core 300S when they operate in sleep mode. And even when running at full speed, they will only generate a maximum noise level of around 50 dB.
In total, there are three different speed levels. The Core 300S also supports automatic mode, in which it will only run as fast and therefore as loud as needed. Once pollutions levels inside the room go back to normal, it will decrease fan speed accordingly.

Sensors & Display
Unlike the Core 300, the Core 300S is equipped with Levoit’s AirSight Plus technology. This enables it to scan surrounding air and provide real-time air quality updates. The same information is also used as input for the automatic mode.
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. You can also use the VeSync app to view the exact level of PM 2.5 particles (see below).

Connectivity & Compatibility
You can use a Wi-Fi connection, your smartphone, and the VeSync app to monitor and control the Core 300S remotely. This allows you to turn the purifier on and off, create a schedule, view the remaining filter life, and more.
It also supports voice control via Amazon Alexa and Google Home. The Core 300, on the other hand, does not come with those capabilities. Instead, you will have to make all inputs on the device itself and might need a third-party device to track air quality.

Weight & Dimensions
In the final round of this Levoit Core 300 vs 300S comparison, we will have a quick look at the weight and dimensions of the two devices. Despite the added functionality, the Core 300S is the lighter model with a weight of just 2.7 kg (5.95 lbs).

Conclusion: Levoit Core 300 vs 300S – Which is the Better Air Purifier?
When it comes to coverage area and CADR, the Levoit Air Purifier Core 300 is just as powerful as the updated version. It might be a good fit if you are willing to miss out on automatic mode and don’t mind manually changing settings while saving some money.
The more advanced of the two devices is, however, the Levoit Air Purifier Core 300S. Thanks to its smart sensors and connectivity features, it is able to adapt to the air quality automatically and can also be controlled and monitored by you from anywhere in the world.
