Mine just jumped from April to August for delivery. You can find your delivery date or switch. I don’t have the room to switch to the other filter. This is what they sent me…
Regarding your Air Filter: We have encountered delays in Glowforge Air Filter production. We had to make significant changes to get the performance we know you want and expect.
You can find the current the shipping estimate for your Air Filter on your Account Page at https://glowforge.com/account
We have, however, been able to source a new option while we finish the Glowforge Air Filter. It’s called the Compact Filter, and it’s a floor-standing alternative that is designed to work perfectly with your Glowforge. The first production run is now available exclusively to customers like you who would like to receive it instead of their Glowforge Air Filter.
