Nikro 860109 40% Cube Filter EC 24"x24"x15"

The Nikro 860109 40% Cube Filter is a replacement pre-filter media designed for use in larger Nikro air handling and air duct cleaning systems where multi-stage filtration is required. This cube style filter (often used as a first-stage or intermediate filter) helps capture larger dust and particulate before air reaches the primary high-efficiency stages, extending the life of downstream filters and improving overall performance. It’s commonly used in systems such as Nikro upright HEPA/duct cleaning units that feature multi-stage filtration setups.
