空氣清淨機 3合1 HEPA濾網 適用338/338S 黑/白

Dropped this into my 338S and it clicked in without any fuss. The HEPA layer is noticeably denser than the old one, and my place already smells less like my cat.

Replacement filter arrived in two days and clicked right into the 338 unit with zero fuss. The 3-in-1 HEPA design means I don’t have to buy separate pre-filters anymore, and the air in the bedroom finally feels cleaner after a week of nightly use.

The HEPA filter slides into my 338 model just like the original, and it's already made a difference in clearing up pet dander. Only minus is that tacked-on $8 shipping fee, which bumps up what feels like a fair price.
