Thanks for reaching out, I’m sorry our last messages sound like they haven’t reached you. @jules and @jbv are correct, though.
We just made an announcement about some major developments to the Air Filter. The short version is that we need to take four months to make changes to the plastics tool to get the best possible performance. In the interim, we are working on providing an alternative product for those of you who would rather not wait. The alternate filter will cost no more than the Glowforge filter, and will be available in October. You can read all about it here: Air Filter Update (September 2018).
