The source-reviewed April 2020 NHP170G guide describes the lower glove-box coupling's lift-before-pull release, filter UP marking and documented replacement interval.

Do not use this older-generation procedure for the 2022-and-newer Sienta.

Easy · 10–20 minutesToyota Sienta NHP170G Hybrid: Replace the Cabin Air FilterNever force the lower glove-box couplings or plastic filter-cover tabs; Toyota specifically warns these can break. Do not run HVAC without its cabin filter, and do not wash or blow-clean the replacement-type filter. The 2020 NHP170G manual is not interchangeable with the later 2022+ Sienta.
