Im still waiting for my air filter. I ordered back in 2015 along with my Glowforge. Received the Glowforge in 2018, I believe. I never got an email stating that they were ready to ship it. Even checked spam folders… nothing. I write them on April 4, 2020. They tell me to fill out a online form that Im ready for shipment. I do that. I hear nothing further. Getting quite discouraged with this nonsense.
You will want to open a new thread in the Problems and Support section of the forum so that they can open a ticket for you. (It’s where you can let them know, support is not going to see it here.)
This post convinced me to get the air filter because I also use a dryer vent, cut mostly acrylic, and have that smell lingering in the room. However, the noise of the air filter is quite deafening compared to my previous set up with an in-line exhaust fan. Does anyone have soundproofing recommendations? Not sure if I’m willing to exchange smell for noise /:
I also paid for my air filter in 2015.
And I can’t hang the hose out a window without seriously bothering the neighbors.
My personal page says the filter is not quite ready.
bummer.
Contact them or post in “Problems and support”. We had to do that to get ours shipped.
I did that, and a glowforge box arrived just 10 minutes ago 
What is the average turn around time for filters now?
Have there been any tests to estimate the impact of the new Light Proofgrade Plywood materials on the air filter cartridge lifespan?
I would like to see how it compares between the Medium Proofgrade Plywood and the Proofgrade Hardwood (since the Light is supposed to have a hardwood core instead of MDF) as shown on this chart: https://glowforge.com/faq/tech-specs#what-is-the-estimated-lifespan-of-the-filter-cartridge
