Discussion of January Update

Question about the air filter. When you announced the new design for the Glowforge Air Filter, you said:

@dan

The new Glowforge Air Filter resembles the Compact Filter, but has three key differences: the cartridges last about 20% longer, it supports a prefilter that can extend the life of the cartridge by another 10%, and it has a notification sound when the HEPA filter is nearly full.

(emphasis mine)

As one of the owners of a shiny new Glowforge Air Filter, I am intrigued by the notion of adding a prefilter, but I haven’t seen any more details. Is this something that’s going to be offered on the Glowforge Shop? Something we have to source for ourselves?
