Always look at the long term cost of any product that needs filters replaced.
Couldn’t find any filters. The links that did show up were old and sold out. Woot did sell them back in 2016.
Too bad they won’t mention what filter models this thing need.
Found this in the Q&A on Amazon. $100 filter though
