The WEN Air Filter Bundle keeps your workspace air clean and breathable. It includes 2 packs each of 1-micron inner filters and 5-micron outer filters specially designed for the WEN 400 CFM Air Filtration System. The 1-micron inner filters use activated carbon to absorb vapors, VOCs, and fine particulates down to 1 micron, providing MERV 10 filtration. The 5-micron outer filters also utilize activated carbon to capture irritants, smells, and dust down to 5 microns, giving MERV 6 performance. Together, this four filter bundle traps contaminants at multiple levels, ensuring only fresh, filtered air circulates your workspace. With easy tool-free replacement, you can quickly swap new filters into most 400 CFM systems. The durable construction stands up to wood dust and workshop debris. Remember when your shop air was fresh and clean? This WEN filter bundle restores that quality airflow to protect lungs and enhance projects. Breathe easy again with multi-stage filtration from WEN.
