How Does the Dyson Core Flow Air Filter Work?

The Dyson Core Flow Air Filter operates within Dyson's air purification devices, which use a sealed system to ensure all air passing through is filtered. The process begins when the device's fan draws in surrounding air from the room. This air enters through the base or sides of the unit, depending on the model, and is immediately directed toward the filter. The Dyson Core Flow Air Filter is positioned in the airflow path, where its HEPA layer captures solid particles. HEPA filters work by forcing air through a fine mesh that traps harmful substances; the Dyson version uses a glass fiber material that meets the HEPA standard, meaning it removes at least 99.97% of particles sized 0.3 microns. Smaller particles may be captured through diffusion or interception, while larger ones are trapped via straining. Simultaneously, the activated carbon layer targets gaseous pollutants. Activated carbon is treated to have a porous structure that adsorbs molecules from the air, such as smoke smells or chemicals from household cleaners. The Core Flow technology enhances this by maintaining a consistent airflow rate, which prevents clogs and ensures even filtration. After passing through the filter, the clean air is expelled back into the room through Dyson's Air Multiplier or other circulation features. This entire cycle is continuous, with many Dyson models offering automatic modes that adjust fan speed based on real-time air quality sensors. The filter's design minimizes resistance to airflow, allowing the device to operate quietly and efficiently. Users can observe the filtration in action through indicator lights on their Dyson purifiers, which signal when the air is clean or when filter maintenance is needed.
