Types of Low Efficiency Filters Ready to Go!
We have two primary lines of low efficiency filters:
GDS

PTA

Our PTA’s metal grid provides an 82% open area and is constructed of a single piece of heavy-duty, one piece craft board frame. It features closed and sealed corners, and the filter media offers a progressively dense fashion from air entering to air leaving side.
Custom Low Efficiency Filters Available
What if you have a special size or frame and filter combination? No problem! We can custom make low efficiency filters in any size, shape, or combination of frame and filter media. If you have the measurements available, we can get you a price quote quickly and let you know the turnaround time. At Twin City Filter, it’s fast and easy to get precisely the filter that you need.
