Design and Build Quality of Levoit Core 300S

The Levoit Core 300S has a sleek cylindrical design made from matte white plastic. It’s 36cm (about 1.18 ft) high and 22cm (about 8.66 in) wide, so it’s small enough to fit into a standard bedroom. 

Furthermore, the bottom has four rubber feet to keep it steady, and there’s a handle-like object to remove the bottom part and reach the HEPA filter. Remember, the filter is wrapped in plastic, so take that off before using the air purifier.

Additionally, the air purifier has a touch-enabled LED screen. It makes picking different air modes quick and easy. The attached cable is about 2 meters long, giving you enough reach to plug it into a power outlet without hassle.

Features of Levoit Core 300S Air Purifier 

Let us explore all the features of this air purifier in detail.

  • Motor and Purification Capacity

The device has a robust 45W motor. This powerful, long-life high-torque motor can cover an area of up to 1095 ft (about 333.76 m) ² and purify the air in large rooms. Moreover, it has a high CADR of 141 CFM (Clean Air Delivery Rate) and can refresh the room within 12 minutes. So, you’ll get a deep and thorough purification of your home. 

  • VortexAir Technology and 360° Air Intake

This technology, combined with a 360° air intake, enhances air purification. So, drawing in air from all directions covers the entire room.

  • 3-in-1 Filter System

The air purifier uses a 3-in-1 filter system to handle different airborne particles. So, this filter can clean it all, whether it’s everyday dust, pollen, or tiny particles as small as 0.3 microns. Furthermore, removing these contaminants relieves allergy symptoms, improving indoor air quality. 

  • Replacement Filters

Choosing the official LEVOIT replacement filters would be best so your air purifier runs smoothly. They have specific options, such as Toxin Absorber, Smoke Remover, and Pet Allergy filters, each made to tackle different challenges. So, avoiding getting an off-brand filter is better, as it might affect how well your air purifier works and lasts.

One standout feature of the Core 300S is its QuietKEAP Technology, which makes the air purifier operate with a gentle hum. In Sleep Mode, the noise level drops to a near-silent 24dB, so you can enjoy a quiet and uninterrupted night’s sleep while reaping the benefits of air purification. 

  • Sleek and Undisturbed Operation

You can turn off this device’s display light so it won’t disturb your space, especially when you are winding down at night. Moreover, it has a timer function and filter lifetime indicator, making things even more convenient.
