Inline Filter Questions

[DaveL]

Jake the best lesson I learned was taught to me by a darn fine furniture salesman. Change something and there's a ripple effect. It affects a whole bunch of things.

I've seen so many people mess up air handling systems in buildings changing filters. I hope the talk here has helped you.

Oddly, it's when the filter is installed CORRECTLY on the back of the machine that it makes the whistling noise.
I have no problems with it being on the mask end, the only issue with that is as I've mentioned before, I'm not sure how effective it is since it's technically flipped to accommodate the hose/mask connections.

Basically, take the image I attached above and rotate it 180 degrees. Now the airflow is going opposite of the arrow.

I'm going to possibly call my DME tomorrow and see what they say about those types of filters.

I appreciate all your input, Daves (ha)
