Hi, My compact filter was working great, but filled up very quickly. Glowforge was nice enough to hook me up with a replacement. I know I’ve seen some posts about adding an additional filter on top of the charcoal filter. Does anybody have any suggestions of what I can use to help my replacement filter last much longer?

There have been some experiments with pre-filters, but I’m not running one.
You might check with @techyg …he was using a cheap filter that he cut down to fit on top of the compact filter and seems to have had good success with it. I’m not sure the brand though.

I am using a Honeywell pre filter. I linked it in this thread but I don’t know how easy it is to find my post. On a mobile right now so hard for me to post more than one link.

Here is a better link for the “pre-filter” I am using with the compact air filter:
I have engraved and cut another 3-5 hours on it since I changed it, including a bunch of bamboo cutting boards, and several pieces of plywood with MDF and veneer cores. I am still on a “3” setting on my Compact Filter. I would say the pre-filter is working pretty well, though I haven’t been a heavy user lately. I am still running the original filter from December and only on a 3 after at least 15 hours of mixed cutting.
