Honeycomb Design: Likely refers to the sensor structure, which maximizes surface area and improves the detection sensitivity for carbon monoxide or other particulates.

Soot Detection: Monitors particulate matter such as soot, which can be a byproduct of incomplete combustion in furnaces or fireplaces.

Blue Smoke Detection: May indicate detection of fine particles, often associated with smoke from oils or cooking.

LCD Display: Provides a clear readout of current CO levels, air quality metrics, or alarm status.
