Pre-filter for traction battery intake?

I'd use a screen rather than a filter. A filter might restrict flow.

 

I've seen several posts that mention "pre-filters" (or screens) but none that specify exactly what these are. It sounds like an add-on for the traction battery air intake.

Where do I buy them?
Dealer, online?
Where are they installed?
Do I really need them?

Thanks for some details,
Bob

 

I put a mesh filter behind the air intake grid (in the back seat cushion in our case). It's a coarse weave, you can see right through it. It's a vacuum cleaner motor filter, I happened to have some surplus, just cut it to size and pushed it in, friction-fit.

 

Thanks, gives me something to think about...

 

Your Toyota dealer's Parts Department can order a snap on "filter" that goes over the back-seat battery air intake. At $30 plus it's something of a rip I think, and it doesn't appear that it would filter very effectively. Never-the-less, I have one on my 2010 hatchback.

 

^ Can you post a pic or link? Thanks.

 

that's interesting, i had no idea there was an oem. someone mentioned cutting up a/c filters in the past. they are similar to the cabin filter material. i think i would prefer a course foam.

 

Here's a couple of pics of what I'm using. I've never heard the fan, though maybe I'm not attentive enough. I've checked it a couple of times, has minimum stuff, a bit of dust and a few airborne seeds.

 

that looks like good stuff. i have have never heard the fan on any of my pri.

 

Lots of good ideas here. Thanks everyone...

Where is this battery intake? I was out yesterday looking through the back seat storage area and could find nothing.

 

In my 2014 Prius v I found it under the back seat on the right side. I had to open the door and lay down on the floor looking under the seat. Hope that helps. (It's not in the back storage area)

Good luck, Bob

 

Agreed. I use a rigid fine mesh plastic screen from a dehumidifier. I cut it to fit over the vent under the right rear seat and taped it in place.

 

Here's the one for the Gen III hatchback, from another thread:
