The Aprilaire 5881 washable MERV 8 filter is a genuine replacement designed for your Aprilaire whole-home dehumidifier family—models E080 and E100—as well as the Dehumidifying Ventilator 8192A and common variations of these units. With a nominal size of 12 inches by 13.5 inches by 1 inch, this filter is built to slide into standard retention rails and maintain a consistent fit across compatible models.
Durable, washable filtration you can reuse
Built around an aluminum frame, a foam core, and an aluminum mesh, the 5881 is designed for regular wash-and-reuse cycles. The MERV 8 rating reflects a dependable filtration level for everyday environments, helping to balance airflow with effective particle capture while preserving dehumidifier performance.
Why a clean filter matters
A dirty or clogged filter can reduce dehumidifier efficiency and may trigger protective shutdowns. Regular maintenance helps your unit move air smoothly and keep humidity levels in check in living spaces.
