The motor in the Core 300 model is much more powerful than that of its predecessor, the LV-H132. This improvement makes the Core 300 a definite upgrade and an ideal selection when shopping for an air-pull device.

Utilizing VortexAir Technology, the Core 300 air purifier produces powerful airflow to clean your environment. According to AHAM’s CADR (Clean Air Delivery Rate) rating system, this device boasts a 230+ms/h rate for rooms of up to 219 sq. ft., making it highly effective and efficient!

Thanks to the durable AC capacitor motor, featuring superior internal construction and high precision bearing, this motor will stand up to wear and tear for years. In return for investing in this reliable device, you’ll receive an extended life of serviceability.

Keep your filters running at peak performance with the filter-replacing indicator! This nifty device will alert you when it’s time to swap out a worn or dirty one so that you don’t have to worry about keeping track of its condition.

The Levoit Core 300 features a convenient timer that you can set for 2, 4, 6, or 8 hours. Once the time has elapsed, the air purifier will automatically shut off to save energy.


Levoit’s Core 300 proudly boasts the prestigious CARB certificate, meaning it meets or exceeds California standards. This is no minor feat since the Golden State has a reputation for passing some of America’s toughest regulations – but then again, Levoit stands out with its first-rate construction and dependability that earn them wide acclaim time after time.

Levoit has been applauded for its latest product, winning the prestigious iF Design Award. Not only is it aesthetically pleasing with a sleek white finish accented by gray details and equipped with an intuitive touch panel on top –

its practicality exceeds expectations as well! Built from BPA-free high-quality plastic, this model promises longevity that one can rely on.

Its wide entry space allows for optimal efficiency as air enters the purifier from all sides and exits through the top – so you can enjoy clean air without it taking up precious real estate in your room!

No matter where you put it in your home or office, you can rest assured that this small but mighty machine has got you covered!

Control Panel

Levoit Core 300

The Levoit control panel is brilliantly designed; it’s incredibly sensitive and effortless to use. The only drawback, in comparison with its successor the Core 300s, is that there are not many advanced functions available.

Additionally, it’s slightly inconvenient that there is no audible beep or any other sound when a button is pressed; this could present an issue if you’re unsure or uncertain whether the button was indeed pushed.

you can control the purifier with a touch panel. When you power it on, all buttons will light up.

To activate or deactivate your device, press the “Power” button.

To control the speed of its fan, select between a low, medium, and high setting using the “Fan Speed” option—simply cycle through them to determine which is most suitable for your needs.

With the simple push of the Sleep Mode button, you can enjoy a night of restful sleep without ever hearing your air purifier working.

Not only will your air purifier begin to operate at its lowest speed, but the illumination from its touch buttons will also dim. Consequently, less light is emitted and you can enjoy undisturbed sleep without having it interfere with your rest.


Boasting a remarkable weight of only 7.5 lb, the Levoit Core 300 is an incredibly portable air purifier with excellent non-slip properties for easy relocation within your home.

Its compact design (8.7 x 8.7 x 14.2 inches) also allows it to fit practically anywhere – be it on side tables, nightstands, or even desks!

Room Coverage

The Core 300 is designed to provide up to 4.8 air changes in a single hour for rooms reaching 219 sq ft or below, effectively creating a fresh and healthy environment.

The Levoit Core 300’s CADR in cubic feet per minute (CFM) is 141 for smoke, 140 for dust particles, and 145 for pollen. With this powerful air cleaning system, you can enjoy cleaner, fresher air with every breath.


Levoit Core 300 leverages a variety of air filtration systems, all available for separate purchases.

Original Filter (Core 300-RF)

The exclusive Core 300-RF filter from Levoit is just what you need for your air purifier. It packs in a powerful triple-layer filtration system with pre-filter, HEPA, and activated carbon components to remove allergens, dust particles, and unappealing odors – all while being incredibly easy on the wallet! With this comprehensive protection against unwanted elements in the air around us, rest assured that each breath will be cleaner than ever.

Pet Allergy Filter

This filter is a must-have for anyone looking to tackle pesky pet allergies and combat disagreeable odors like litter stink, cooking smells, and even bathroom odor. It has all the great features of its Original counterpart plus an added high-efficiency activated carbon component, which will help you forget those unpleasant aromas altogether!

Toxin Absorber Filter

Just like the Pet Allergy filter, this one offers all of its benefits plus even more. It is equipped with a high-efficiency activated carbon filter that is extremely effective against strong odors such as smoke, cigarette smoke, toxic fumes, VOCs, and vehicle exhaust. In addition to other types of air pollution, it helps remove from your home environment.

Mold Bacteria Filter

The Mold Bacteria Filter ups the ante on air purification with an enhanced filter that combats organic pollution as well as germs. In addition, it guards against the growth of bacteria and mold within the confines of your home’s air purifiers for a healthier indoor environment all around.


To evaluate the efficacy of Levoit Core 300, I conducted a series of performance tests in varying room sizes. To ensure accuracy, all trials were carried out in real-world settings—not laboratories. In each test, the device was set to its highest speed (the third one).

194 sq. ft. Room Test

Despite this room being smaller than what is usually recommended (219 sq. ft.), the Core 300 air purifier stunned me with its impressive performance! Even though it has a powerful motor, I still wasn’t expecting such incredible results.

In a mere hour, the Air Quality Index (AQI) experienced an extensive plummet from 111 to 8 – representing an unbelievable 93% improvement. After another thirty minutes elapsed, AQI sank further still to 6!

320 sq. ft. Room Test

Even with an area that was more than double the size of what Core 300 recommends, this room’s sound quality didn’t suffer. In fact, it did an impressive job amplifying sound in its enormous proportions!

Believe it or not, the air quality improved by a whopping 92% within one hour of using this system! The AQI dropped from 145 to 12 after just sixty minutes – an incredible improvement that is hard to ignore.

Power consumption

The Levoit Core 300 is an Energy Star-certified product, meaning that it uses a remarkably small amount of energy for operation. Its power consumption does not exceed 45W!

The Core 300 runs at full speed for 24 hours every day, yet only costs 3.8$ monthly if the energy rate is 0.12$/kWh. Even when it’s on standby, Levoit states that its energy usage will remain below 0.8W; my own testing results suggest a mere 0.2W consumption!


In my opinion, the maximum noise level of 64.9 dBA may be a bit too loud for those who want to use it in their bedroom or any peaceful environment.

Speed Value (dBA)

Sleep mode 40.7 dBA

Speed 1 46.4 dBA

Speed 2 52.9 dBA

Speed 3 64.9 dBA
