Rabbit Air MinusA2 HEPA filter with replaceable / customizable filter types.

Note from owner (selling for him since he already moved):
I bought this new and replace the filter once a year because I run it continuously.
The current filter is full of dust / particulate so you’ll need to throw the filter out (easy) and replace it (roughly $100 each IIRC)
Pickup from Munger, preferably as soon as possible. $50 OBO.
