TOYOTA Prius HSD - Manual (Page 29)

Air-Conditioning
Filter Access There is a Hepa filter for the Air-Conditioning system (Toyota Part: 87139 - 47010) directly behind
the glove-box, which can be changed without any tools. Roughly every 30,000 miles or so (around
48,000 km) replacement will be needed.
Open the bottom glove-box, and then remove all the contents (since they will end up falling out all
over the floor otherwise).
To the right of glove-box is an attached small plastic hydraulic arm (to add a resistance feel). Pull
on that arm so it separates itself from the glove-box. Then hold onto the left and right sides of the
glove-box while squeezing inwards. This will allow you to pull the glove-box downward, beyond
the usual stopping point. Having accomplished that, you may let go. Just let it hang there, like this:
The air-flow assembling will then be completely visible and very easy to access. You’ll see the
filter at the top, lying horizontal along the entire width of that white plastic air-duct. Just pull on
both sides to slide it out. Then you can easily inspect it and replace it (when needed).
