Snapmaker Air purifier - is it worth it?

Just started using the 10W Laser which I’m venting outside using the enclosure’s fan via the study window, however I was looking at the Air Purifier and it seems rather expensive in terms of the one of purchase and even more so for the replacement cartridges. I’m assuming the estimated 3 month lifespan is based on run time rather than actual time from installation.

So, my question is, is it worth the expensive, even with a holiday/special occasion discount?

My current intention is to instal an inline extractor, into the cabinet that I’m building and vent out the window but I need about 8 feet of hose which causes it’s own issues as well as an open window.
