I recently discovered that Toyota hybrids come with a battery air filter. I have a 2019 model, and now I plan to change it every year, just like my cabin filter.
You probably haven’t been following that car care guy on this forum, huh?
I always watch his stuff
Are you sure you’re not a stalker? 
You always… watch… him… 
Doesn’t everyone watch his videos?
Haha, it’s just a joke, my friend! Watching someone all the time is kinda what stalkers do
LOL, someone here gets it! The other person in this thread takes everything too seriously and downvotes everything 
Gotta love forums like this!
I thought it was funny, don’t worry about it 
Great minds think alike!
Wow, you really don’t know how to use ellipses… Let me explain, three dots break a sentence, and four end one. If you’re showing emotion, a question mark or exclamation with dots works too, like this…?
Not reading all that 
I watch him sometimes, but I take his advice with caution. I’ve had oil tests done, and the results don’t always match what he says. But hey, the guy knows his stuff, so I still listen to his tips.
You should check it now and then, especially to keep the battery cool.
The Sienna Hybrid actually has two filters, one under each front seat.
If you’ve got dogs (I’ve got two), you’ll need to check the filter more often. Dog hair can’t be good for it.
Why replace it? It looks clean to me.
You could just vacuum the outside of it.
Annually? Really? Lol
The interior air is already filtered by the cabin filter, so it’s not that weird to think this one can last longer.
