This model, while functional as is, would be potentially more useful if one of the two limbs on the Y-piece was longer than the other by approximately 19 to 25 mm.  The extra length on one limb would allow two respiratory therapy B/V or HEPA filters to be used, one on each limb.  There are many different brands of respiratory therapy filters available and there is no standardization with respect to size and shape.  So, while some brands may fit the existing device, others may require one limb to be longer so that the two filters do not encroach each other.
