Replace 2010 Prius Cabin Air Filter

Cabin Air Filter on Amazon ($8.87)

Procedure:

• Open lower glovebox.
• Push one side inward while pulling out to release tab.
• Do the same for the opposite side.
• It is enough to lower and tilt the box downward without completely removing it to access the air filter.
• Pull the right tab on the filter cover to release it, then remove the filter cover.
• Remove the old filter (note it’s orientation with the arrow facing forward and pointing up).
• Insert the new filter (same orientation).
• Replace the filter cover snapping the right tab in place to lock it.
• Reinsert the glovebox tabs one side at a time.

In my case, the plunge rod on the right fell out (an “oh shit” moment).  It took me a little while to figure out how to put that back on.

Tabs on filter cover circled in red.

Shows where the plunge rod goes if it falls off and you need to put it back.

Shows dirt trapped in the old air filter.  Better there than in your lungs.

Toyota says to replace this filter every 30000 miles or every 3 years.

EPAuto recommends that it be replaced every 12000 miles or every 12 months.
