The best air purifier isn’t always one that’s the best large room air purifier; sometimes great things come in small packages. And that’s exactly what the Levoit Core 300 delivers. It doesn’t have the most powerful fan speeds, but it makes up for it with a 360-degree air flow filtration.

Why We Like It – Levoit Core 300

With its 360-degree filtration, the Levoit Core 300 outputs surprising performance, despite its smaller size. It’s also incredibly quiet and certified by Energy Star in its energy efficiency.

  • 360-degree filtration
  • Low noise levels
  • Energy Star certified
  • Not a large coverage area

Power & Speed

Compared to the Medify Air MA-112 V2.0, the Levoit Core 300 isn’t exactly packing a lot of power—but don’t let that change your mind. It delivers air around the room up to 135+ CFM. If you consider placing it in a small room, these particular Levoit air purifiers perform far better.


Sure, the Core 300 isn’t beefed up for power, but it’s still incredibly efficient at providing better air quality when placed in the right room. For the best performance, place it in a room no bigger than 215 square feet, which is admittedly small, but better suited for bedrooms or small offices. It’s also energy efficient, seen by its Energy Star certification. For more coverage, consider the Alen BreatheSmart Classic Large Room Air Purifier.


So, how is the Levoit Core 300 still good, despite being lesser in power? It has two great design features going for it: a 3-stage filtration system and 360-degree air flow. It starts by sucking in air all around it, into the pre filter, capturing large bits like pet hair and dust. Smaller particles come up against the True HEPA filter, taking care of 99.97% of pollen and bacteria as small as 0.3 microns. Lastly, the activated carbon filter takes care of odor from smoke and pets.


The Levoit Core 300 looks premium, and it’s built to be. Underneath the hood, the AC capacitor alone has durable, high-precision bearings. It’s also highly resistant to abrasions, increasing the shelf life of the device.


Who is this for, exactly? If you have a small room to purify, like a child’s room or kitchen, this is it. The price is right, as is the performance. For bigger rooms, the Coway Airmega 400 holds more value. But what’s neat about the Core 300 is the ability to swap out its original filter, so if you suffer from a pet allergy, you can get a replacement filter to specifically target it. Just remember air filter replacement costs.

Levoit Core 300 Wrap Up

While the Levoit Core 300 isn’t the most powerful unit, it was never meant to be. The value here is cleaning air around your personal space. To know you’ll have clean air while you sleep (using Sleep Mode, too) is only going to help you sleep better. It’s quiet, energy efficient, and versatile in the way it handles unclean air.
