Merv 11 Practical Pleats in stock:
The Updraft Practical Pleat 5" thick pleated filters are designed to fit into air handling units that normally use a 1" filter, but has enough room for a deeper filter; as well as anywhere else where reverse airflow is needed. The airflow is reversed on the Updraft Practical Pleat, note the arrows' direction in the photo. Simply remove your old 1" filter, and slide the Practical Pleat into place!
