Meet Ig0R - The Deconstruction of a Glowforge Filter

Okay, so it’s a diy filter, yes?

close. . It’s a DYI - REPACK of the glowforge filter for like 1 / 10th the cost
a step by step how to do it.

I am adding iG0r to my frakenforge so its completely self contained.
since I am producing glass dust, and no real wood / acrylic smoke, I think
a external filter will be a winner…

Are you also planning to “vacuum out all the rocks”? :upside_down_face:

I’d be curious where you’re sourcing activated charcoal filter media for that price point. From what I understand the filter uses quite a lot of that, replacing the media for 1/10th the cost ($25) would seem like a stretch, not to mention the other filter components.

To be clear, those pictures are from This happened to my Air Filter

Is that the same as activated charcoal?

I use something similar as a pre-filter when I use my filter.

Says it is
Gotta believe amazon

I’m confused - that carbon pad isn’t remotely the same as pile of carbon chunks. (being mostly polyester webbing with some carbon dust sprinkled in)

I won’t know till I have it installed and I do smoke tests.
its all theory and speculation at this point, why I am “not starting” this thread till TOMORROW :slight_smile:

That is more like what I was expecting.

We all talk and speculate… but no one DOES and documents.
seems to be my bailiwick

I do love the other filters for a pre-filter though!

Catch the nasty glue/sap residue before it hits the expensive filter.

hmm $60 for The 15 lbs (well 13.5) needed

**As promised… **

I decided it was time to dissect a Glowforge filter, and just see what that $250.00 buys us!

Box 14 3/4 “ x 9” x 9” deep

Stage one - 13.5 lbs charcoal

Stage two – thin filter to prevent charcoal dust

Stage three – 1” paper filter (fanfold)

Stage four - 2.5” paper filter

Stage five – Thin filter

Everything is silicone into place, all joints are silicone

All edges, filters are glued into place with silicon

HOW I DID IT…

I used a drill / tap to remove all rivets and tap the case so I can replace the rivets with small flathead screws (for future cleaning / filter swaps)


I then used a thin bladed scraper to break the silicon seal around the seams of the case

Once removed, replace the filters / charcoal – re assemble, use screws to reseal unit.

DONE!

‘parts’ Costs will be done in a future post (soon)

AND the repack

Take a scissors and cut 2 - 9" pieces (you should end up with 4 using both sheets)

I added in each filter flipped so the cardboard would layer the lower opening
to give a better seal between layers (use three cut pieces total)


What it looks like in the filter Cartridge

And WHAT it costs me!

add 3 - bags of 5 lbs of carbon for $60 from amazon.
screw the thing back together. DONE!

[Legal disclaimer]
There is no guarantee that this works as well, or better then an official Glowforge filter cartridge, But then again, we have no guarantee how well those work either :stuck_out_tongue:
