The LEVOIT Core 300S+ Mini Air Purifier and Essential Oil Diffuser combines advanced filtration with gentle aromatherapy in a compact package. In this comprehensive review, we’ll explore the device’s features, examine its performance, offer a buying opinion, weigh the pros and cons, and help you decide if it’s the right choice for your space.
Product Description
Design and Build
The LEVOIT Core 300S+ Mini stands just under 12 inches tall with a sleek cylindrical profile that fits neatly on a nightstand, desk, or countertop. Its matte-white housing pairs subtle LED touch controls with an accent ring of soft, glowing light at the base. The top cover lifts off easily to reveal a dedicated chamber for essential oils, while the lower section houses a three-stage air filter. Despite its petite footprint, the overall aesthetic feels modern and unobtrusive, blending into bedrooms, home offices, or nurseries without drawing undue attention.
Filtration System
At its core, the purifier utilizes a three-stage filter assembly:
-
Pre-Filter: Captures large particles such as hair, dust, and pet fur, extending the life of the more delicate layers below.
-
True HEPA Filter: Removes up to 99.97% of airborne particles down to 0.3 microns in size—this includes pollen, mold spores, smoke, and fine dust.
-
Activated Carbon Layer: Adsorbs volatile organic compounds (VOCs), household odors, and some gaseous pollutants for fresher-smelling air.
The filter stack sits beneath the removable bottom cover and can be swapped out in seconds whenever replacement is due.
Diffuser Functionality
In addition to purifying air, this model doubles as an ultrasonic essential oil diffuser. A small reservoir atop the unit holds perfume-grade oils (droplets only, never direct liquid), which are dispersed as a fine aromatic mist alongside the purified airflow. This dual capability delivers both cleaner air and your choice of fragrances—from invigorating citrus to calming lavender—without requiring a separate diffuser on your shelf.
Smart Controls and Connectivity
The Core 300S+ Mini pairs via Wi-Fi to the LEVOIT smartphone app (iOS and Android), granting remote control over fan speed, diffuser intensity, and timer settings. You can schedule on/off cycles, monitor filter life, and adjust the integrated night-light color. For voice enthusiasts, the unit also supports Amazon Alexa and Google Assistant commands, enabling hands-free operation like “Alexa, turn on the air purifier” or “Hey Google, set diffuser to medium.”
Performance and Real-World Use
Coverage and Airflow
Although marketed as a “mini,” this purifier capably handles spaces up to 150 square feet—ideal for bedrooms, small living rooms, or office cubicles. On its highest fan setting, it circulates and filters the full volume of air in such a room roughly three to four times per hour, ensuring consistent pollutant removal. Lower fan speeds still provide meaningful filtration with quietly whisper-quiet operation, making it suitable for overnight use.
Noise Levels
Measured in decibels, the noise ranges from a barely audible 20 dB on the lowest setting—softer than a whisper—to about 48 dB at maximum speed. The gentle hum remains less intrusive than many larger purifiers, and the integrated LED base light can be dimmed or disabled entirely for uninterrupted sleep.
Diffusion Effectiveness
Adding a few drops of essential oil into the reservoir fills the immediate vicinity with a pleasant aroma within minutes. Because the oil-infused mist is carried by the airflow, it disperses more evenly than stand-alone diffusers, subtly scenting corners of the room without drenching surfaces or leaving oil residue.
Energy Consumption
LEVOIT’s Core 300S+ Mini draws less than 5 watts on its lowest setting and peaks around 20 watts on high. For comparison, a typical 60-watt incandescent bulb uses three times more energy than this purifier in its maximum mode, making it an energy-efficient all-day companion.
Buying Opinion: Is It Worth It?
Compelling Reasons to Buy
-
Dual Functionality: Merges air purification and aromatherapy into one space-saving device, eliminating the need for separate units.
-
True HEPA Filtration: Guarantees capture of microscopic allergens and particulates for noticeably cleaner air.
-
Smart Features: Remote scheduling, voice control, and filter-life tracking add user-friendly convenience.
-
Quiet Operation: Ultra-low noise on sleep mode ensures restful nights without background hum.
-
Energy Efficiency: Consumes minimal power, keeping electricity costs negligible even with continuous operation.
Reasons You Might Pass
-
Limited Coverage: Best suited for small to medium rooms; larger living areas will require a full-size model to achieve similar air-change rates.
-
Diffuser Capacity: The essential oil reservoir holds a modest amount; heavy aromatherapy enthusiasts may find themselves refilling more frequently.
-
Wi-Fi Dependency: Some users prefer straightforward plug-and-play appliances over app integration and network setup.
-
Ongoing Filter Costs: Replacement HEPA/carbon filters add to the long-term cost of ownership, though pricing remains in line with industry norms.
If you live or work in a smaller space and value a two-in-one solution with smart controls, the LEVOIT Core 300S+ Mini presents an excellent balance of features and performance. If you need to purify air in a large open-plan area, consider pairing multiple minis or opting for a more robust standalone purifier.
