3d printed Airsense10 bayonet filter safe?

Just bought a 3d printed Galeith Airsense 10 3m bayonet filter adapter. It is a 3d printed part that looks to made of PLA. It has lots of ridges and stringy bits that need to be removed. If I wash this thing thoroughly am I taking a significant risk by breathing through it every night?

I 3D-print a lot. "Common" knowledge on the internet is that PLA is "safe" plastic. The thing is, it's not a regulated product, and there is no control over what additives go into "PLA" (or any other type of plastic). Anecdote: When I had 3D printers in the room where I was sitting all day, I started to have a lot of headaches and cough. Very likely, it was fumes released when melting the plastic for printing. After I moved printers to the garage and added forced venting, issues disappeared in a week and never returned. The final product may not be subject to as much off-gassing as melting one, but who knows...

Things like tube-mount hooks, various external holders, etc., should be okay, but I would personally avoid using anything that could off-gas and get directly into the airflow. It's a great technology to prototype things and figure out the final design, but I wouldn't trust it regarding health.

My $0.02. Maybe some other forum members have used it for a long time and could share their experiences.

Given that filters manufactured by medical companies are so cheap, why bother?

Have you got a picture or link for it? Interested to see what it is.

I've only been able to find it on Amazon searching for "Galeith Airsense Filter" (looks like they make them for the Airsense 11 now as well). Galeith seems to be a trademark of of Shouguang Taotu E-commerce Co. that makes various electronic goods. It has a rough surface and stringing, I am considering returning it because of the uncertainty with the safety of 3d prints. People say the 3m filter is much more effective than original. It's a pretty neat idea; hopefully somebody makes a food-safe injection-molded version eventually.

Thanks, I found it on Amazon. Looks like they are using a 3d model that someone posted on printables.

I did a version that uses 2 x 3M filters as that's what the 3M respirators use to ensure low inhale resistance and I think is safer for your machine as puts less load on the motor. Mine can also be mounted remotely so your not breathing dusty air from the back of the side table!

I printed mine in Bambu Petg filament that is FDA food safe, so should be safe to use for respirators too. Mine is printed with supports that have to be carefully removed to make sure there's no stray strings as you wouldn't any loose filament to be drawn into the machine. But that easily done and you end up with a very tidy adapter that works really well. I sleep so much better knowing that I'm not breathing in dust and mold spores which get more concentrated at cpap pressure.

If you don't have access to a 3d printer you can use a service like PCBway to print one for you.
