Couldn't find out what size replacement filters this takes. Not even a model number of the whole purifier. Amazon does sell some Yiou filters, but it's unclear if you'll be able to find the size for this one (unfortunately, replacement HEPA filters are not standardized; each brand has their own dimensions).

ETA: also, this thing is tiny (8.25 x 8.25 x 13.75) so I have to doubt its whole room coverage bona fides. I did, however, figure out that it is probably the S1/HY3800 filter
