Filtration Performance

True HEPA Technology

Both models utilize True HEPA filters that capture 99.97% of airborne particles as small as 0.3 microns. This includes:

  • Dust and dust mites
  • Pollen from trees, grasses, and weeds
  • Pet dander
  • Mold spores
  • Smoke particles
  • Bacteria and some viruses

Activated Carbon Layer

Each unit includes an activated carbon filter layer that helps neutralize odors and capture volatile organic compounds (VOCs). Whether youre cooking, dealing with pet smells, or living in an area with pollution, both models handle odors effectively.

Coverage Area

This is where the models differ significantly:

  • Core 400S: Designed for medium to large rooms up to 403 square feet. Perfect for master bedrooms, living rooms, and home offices.
  • Core 300S: Ideal for smaller spaces up to 219 square feet. Great for guest bedrooms, nurseries, and small offices.

If you have an open-concept home or want to purify air in a larger area, the Core 400S is the better choice. For apartments, smaller bedrooms, or personal spaces, the Core 300S offers excellent performance at a more compact size.

Smart Features and Connectivity

Display Differences

The Core 400S features a more advanced LED display that shows real-time PM2.5 readings, giving you immediate feedback on your air quality. The Core 300S has basic LED indicators that show fan speed and WiFi status but dont display specific air quality metrics.

Noise Levels

Both models operate quietly, especially on lower fan speeds:

  • Core 400S: 24-54 dB depending on speed setting
