In-depth Review of Levoit Core 300 Air Purifier:
Design & Usability
The Levoit Core 300 air purifier is a sleek cylinder that stands about 14 inches tall and has a diameter of 9 inches. The bottom half of the unit has a mesh grille that takes in air, while the top delivers purified air through a vortex-shaped outlet.
The delicate touch control panel is located on the top of the unit and is very responsive. It features all the necessary settings such as three different fan speeds, a sleep mode, timers, and display off.
You can also lock the display to prevent accidental changes to the settings.
Levoit Core 300 comes in two colors: white and black. I have the white one, and it looks great in my home office.
The unit weighs 7.5 pounds and comes with a robust 6-foot power cord.
Ozone-free 3-in-1 Composite Filter
As I mentioned, the Levoit Core 300 is a value-priced air purifier, but that doesn’t mean it skimps on features or quality.
The unit uses a 3-in-1 composite filter that captures 99.97% of particles as small as 0.3 microns. The filter comprises a pre-filter, an H13 HEPA filter, and an activated carbon filter.
The pre-filter blocks the larger particles such as pet hair and dust, while the true HEPA filter traps the smaller particles such as smoke, bacteria, and viruses.
I have tested the filter efficiency with an AQI meter at the air outlet, and the results are awe-inspiring. As you see from the images, it virtually traps all airborne particles from the air.
The activated carbon filter helps reduce odors, smoke, and VOCs (volatile organic compounds).
Unlike activated carbon filter pads, Levoit Core 300 filter has real activated carbon pellets. However, the amount of carbon is minimal and unsuitable for a heavily odorous environment.
I’ve been using the Levoit Core 300 for about two months, and it works as advertised.
The unit is very effective at removing PM particles from the air. When running at the highest setting, the PM2.5 readings on my AQI monitor drop by about 50% within 10 minutes in my ~ 200 sq ft room.
Here is the result:
- At 7:00PM > PM2.5 Level is 40 µg/m3
- At 7:10PM > PM2.5 Level is 19 µg/m3 (about 50% drop within 10 minutes)
- At 7:20PM > PM2.5 Level is 9 µg/m3 (about 80% drop within 20 minutes)
As you can see from the images, the Levoit Core 300 air purifier effectively reduces PM2.5 levels in the air.
When using the Levoit Core 300 consistently, I feel that the air in my home office is lighter to breathe.
Since the model doesn’t have an air quality sensor, I set it to run on the lowest fan speed after running it on the highest setting for 10-15 minutes to remove the majority of PM particles from the air.
The lowest setting is tranquil, and I can barely hear it. It also has a sleep mode, which is even quieter.
If you need smart features, you can consider the Levoit Core 300S air purifier, which is the same model with the addition of a Wi-Fi connection and an embedded air quality sensor.
The Levoit Core 300 is straightforward to maintain. The filter has a life span of 6-8 months and is very easy to replace. Just twist off the bottom cover and pop the old filter out.
Regularly cleaning the pre-filter will also help prolong the life of the HEPA filter. You can also sunbathe the filter to reduce any musty smell coming out from the filter.
Here is the condition of my purifier’s filter after 2 months of usage:
As you can see from the image, the filter is still in good condition. I’ve only vacuumed the outer side of the filter twice to remove the visible dust.

Pros & Cons:
The Levoit Core 300 is a great value-priced air purifier that does an excellent job of filtering out PM2.5 particles from the air. It’s also very efficient at filtering out other tiny airborne particles such as smoke, bacteria, and viruses.
The unit is very easy to maintain, and the filter has a life span of 6-8 months.
If you’re looking for an affordable air purifier that doesn’t skimp on features or quality, the Levoit Core 300 is a great option for medium-sized rooms.
I bought a brand new Levoit 300 air purifier and it does not work. It had never been opened and still had the directions n the box.
It turns on but the fan does not work. The company will not allow me to return it nor will they replace it because I purchased it through a third party vendor. It is obvious they were being sold through this vendor because they were defective in the first place. I would not recommend this product to anyone. What an awful company.
