Good comparison. Also likely similar to other Puro made for commercial filters like ProMotive/Group7. And as mentioned, many/some applications are downsized and consolidated. Look similar to/same as a Classic, but likely not a clone in efficiency. Based on the dissections posted here though a well made filter.
