The orientation of the patient circuit does matter. The filter should be on the expiratory port of the machine. The inspiratory filter for the patient is on the other end. There's no need to filter the inspiratory breath twice.
If you’re going to demonstrate a product, please do not instruct your audience not to utilize the Sensory function. It is up to the provider, not the Rep, to decide whether the Sensory function is necessary. It is on there for a reason., and many providers still do use it. While it can be assumed the Sensory interface operates identically to the Motor interface, you should say as much instead of teaching your audience to skip it, please. The sensory function is very useful, as the more accurate the needle placement, the lower the Sensory voltage should be. 👍🏻
