Question: What does 'with frame' and 'no frame' mean on your intake filters?
Answer: This denotes if the intake filter has an internal wire supporting frame. Most spray booth intake filter pads come with an internal stiffening frame that allows the filter to be retained in the intake filter cell. The Custom Tacky series pads are reusable and have removable internal wire frames. When reordering CT series filters, just order the same size with no frame for lower filter and shipping costs.
