CleanSeal 800 Mini-pleated air filter is designed with tightly packed pleats, significantly increasing its surface area and filtra on efficiency. Class One
Cleanrooms mini-pleat filters are constructed using high-efficiency fiberglass filter media, both of which are waterproof and flame-retardant. This design not only makes the filter compact but also enhances its dust-holding capacity, ensuring superior performance in high-demand environments.

To ensure the integrity of the filter, an adhesive is applied to eliminate air bypass and form a rigid structure, preventing any gaps between the media and the frame. Each filter is laser-tested to guarantee heat resistance up to 80°C, ensuring reliable performance under varying conditions. The optimized aerodynamics structure of the filter also ensures a low pressure drop, promoting strong airflow and better ventilation, even in demanding HVAC systems. As a trusted supplier of mini-pleat HEPA filters, Class One Cleanrooms has heavily invested in improving filter performance. These filters offer multiple times the surface area of traditional filters, which results in better filtration, higher performance, and a longer service life—allowing for less frequent filter replacements.
