Now, let’s explore the key differences between the Levoit Core 300S and Core 400S air purifiers to help you make an informed decision.

1. An Insight Into Filtration System

Both the Levoit Core 300S and Core 400S utilize a comprehensive 3-stage filtration system to ensure the air you breathe is free from harmful particles:

levoit 300s vs 400s filtration

  • Stage 1: Pre-Filter: This initial filter effectively captures larger contaminants like dust, hair, and pet fur.
  • Stage 2: HEPA Filter: The second stage employs an H13 True HEPA filter capable of clearing impurities and allergens as small as 0.003 microns, including pollen and pet dander.
  • Stage 3: Activated Carbon Filter: In the final stage, a layer of activated charcoal removes VOCs, chemicals, cooking smells, pet odors, and fumes.

Winner: I will call it a draw as both purifiers share the same trait when it comes to filters.

2. A Comparison of Coverage Area & Efficiency

In terms of the coverage area of the former model;

  • The 300S has an effective range of 219 sq ft.
  • It is designed for smaller rooms.
  • The Core 300S models deliver CADR ratings of 240 m³/h (141 CFM).

On the other hand, the 400S :

  • Boasts a higher range of 403 sq ft.
  • It can handle bigger and more open floor plans.
  • The 400S has a better rating of 442 m³/h (260 CFM).

With the inclusion of VortexAir Technology, the cleaned air is evenly distributed throughout the designated room. While the 300S purifier can also be used in larger rooms, the air purification process may take slightly longer.

Winner: The 400S takes the lead by giving a higher coverage for purification. The 400S also excels in removing smoke, dust, and pollen, with a CADR rating of 260 CFM.

3. Working Noise Of Both Purifiers

Both the Levoit Core 300s and Core 400S models feature whisper-quiet technology, ensuring a peaceful environment.

  • Both of the both have the same noise level at the lowest setting of 24 decibels.
  • When on the highest fan speed setting: The 400S has a higher sound of 52 decibels as compared to 48 decibels of its counterpart.

4. How Both Purifiers Differ in Power Consumption

Both the Levoit Core 300S and Core 400S models are Energy Star certified, ensuring energy-efficient operation.

  • However, the Core 300S consumes lower power, with a rating of 26 W compared to the Core 400S, which has a power rating of 38 W.
  • This makes the Core 300S both eco-friendly and cost-effective, helping you keep your electricity bills in check.

Winner: The 300S is the better choice among the two when it comes to saving your energy bills, but on the downside, you will need to compromise on the efficiency the 400S has to offer.
