Overview
The Levoit Core 300S is the smart evolution of the brand's highly popular Core 300 air purifier. It takes a proven design and enhances it with a suite of modern features, including Wi-Fi connectivity for app control and an integrated air quality sensor that enables automatic operation. Positioned as a mid-sized unit for smaller rooms, the Core 300S targets users who prioritize convenience, real-time feedback, and the ability to manage their home's air quality remotely without paying a premium for large-room coverage.
Key Features
The Core 300S builds upon its predecessor's foundation by adding significant smart capabilities. These features transform it from a manual appliance into an automated air quality system.
AirSight Plus Technology & Auto Mode
The most significant upgrade in the Core 300S is the inclusion of Levoit's AirSight™ Plus technology. This feature uses a laser dust sensor located on the back of the unit to scan the surrounding air for airborne particles in real-time. This data is then translated into an easy-to-understand visual indicator on the top control panel. A color-coded LED ring changes based on the detected air quality, giving you an at-a-glance update. More importantly, this sensor enables the unit's Auto Mode. When activated, the Core 300S will automatically adjust its fan speed to respond to changes in air pollution, increasing power when needed and conserving energy when the air is clean. This offers a true 'set-it-and-forget-it' experience.
For the most accurate automatic performance, be sure to keep the AirSight Plus sensor grille on the back of the unit clean and unobstructed by dust or furniture.
VeSync App & Voice Control
As a 'Smart' model in Levoit's lineup, the Core 300S connects to your home's Wi-Fi and integrates with the VeSync mobile app. This unlocks a host of remote-control features, allowing you to power the unit on or off, change fan speeds, set schedules, and view real-time and historical air quality data from anywhere. For those integrated into a smart home ecosystem, the Core 300S offers voice control through Amazon Alexa or Google Assistant. This allows for hands-free operation, a convenient feature when your hands are full.
Full access to scheduling, historical data, and remote operation requires the air purifier to be connected to a Wi-Fi network and paired with the free VeSync app.
Customizable 3-Stage Filtration
The Core 300S utilizes a cylindrical all-in-one filter that incorporates a 3-stage filtration process. The first stage is a fine non-woven fabric pre-filter that captures large particles like dust, lint, and pet fur. The second stage is the main particle filter, which handles finer contaminants. The final stage is a high-efficiency activated carbon filter designed to neutralize household odors and volatile organic compounds (VOCs). Levoit also offers several specialized replacement filters for the Core 300 series, including a Pet Allergy version with a higher-efficiency carbon filter for pet odors and a Smoke Remover option to better tackle smoke and other strong fumes.
For homes with significant odor, smoke, or VOC issues, upgrading to a specialized filter like the Smoke Remover model is recommended.
