I posted this on FB, some liked it, some didn’t. To me its a great idea. This was shared with me from a friend Robert Brock who made it for his. I just ordered the filters so I can make my own. To me, its like a small filter on a CPAP machine, change it or blow it out every 30 days and it should work just fine.
A small modification to the filter case has to be made to allow it to fit over the controller bolt head.
Take it for what you want, I’m just sharing it.
