There’s also a display-off function to ensure your room stays dark during the night, free from any annoying LED glare.

Even at higher fan speeds, the sound is relatively low, similar to a soft fan in the background. This makes it suitable for daily use without being a disturbance.

User-Friendly Design

With its minimalist cylindrical shape, the Core 300‑P looks good in any room. It’s lightweight and easy to move from space to space. The touch controls on top are simple to navigate—no apps or smart assistants required.
