- Dust removal for PM2.5 and above, sound insulation function of 30 dB(A) or more -
Dust with a particle diameter of PM2.0 or larger is collected at over 70%, and the noise has a sound insulation performance of 30 dB(A), which is great news for the air supply vents of ventilation systems in general residences.

basic information
To satisfy a ventilation rate of 15 m³/h or more based on JIS standards, several geometric airflow passages have been established. Among them, one airflow passage features a uniquely shaped geometric screen plate in a W or M shape, with sound-absorbing rings installed between the connections. As air passes through the geometric screen plate, it collides with the horizontal inertia of the screen plate and sound-absorbing rings, creating several negative pressure zones. This gradually pushes dust and moisture into the negative pressure zones, allowing for the physical treatment of dust and noise contained in the air, enabling dust removal, dehumidification, sound absorption, and sound insulation. This system utilizes the pressure difference between indoors and outdoors and natural wind power, making it a non-powered (no electricity required), eco-friendly, and energy-saving air purification and sound absorption system air intake filter.
