[Equipment] Adding a diffuser to the exhale holes

[zenmaple3]

Is there a way to add or make a diffuser/filter for a mask that doesn't already have one? The exhale airflow from the front of the mask is so disruptive: it blows and bounces back on me, and it also blows on my partner. I have tried many masks, and I currently use a resmed airfit n20. (I am thinking of the kind of clip on filters that come with the Fisher & Paykel Brevida Masks)

This is something I've thinking about for a couple weeks but haven't done anything about yet. Searching the Internet, I found a couple people who've modified their masks with DIY diffusers. The way I was thinking to do it is via 3D printing a plastic piece designed specifically to fit my mask. I later noticed that the Bleep mask has a piece of cloth that wraps around the vents and has a filter to diffuse the air; that looked easier to do than 3d design.

A piece of gauze should provide some diffusion.  You may wish to look into a gauze bandage product named, Kling.  It is a stretch conforming gauze that will adhere to itself. Adjusting the number of wraps would allow for the best trade off between ventilation and sound.
