Got a question.

I want to install my carpc into the glove box compartment. Please tell me, is the air heater placed before or after the cabin air filter? I wouldn`t want to fry my computer during winter time..

Thank you!

Air flow goes down so it is heated after it goes through the filter and after the fan.

oh, good news then, I will use the airflow to cool the processor :)

Thank you!

great work and idea. But i work for a local parts store and the filter only costs me $10.74

Thanks so much for this DIY, I get free filters here at the apartment complex where I live, so I am going to craft me a filter cartridge now! You guys rock!

I'm glad I found this forum. Sure enough, my 07 HB did not have a cabin filter installed. I just bought the allergen rated NAPA version, part #: FIL 4483. I figure $16 a year isn't going to kill me. Especially compared to what the dealer would charge for a 2 minute installation.

Just picked up the NAPA 4483 at my local shop. I was wondering why the dashboard and inside of the car was so dusty.
How strange that a $16 part was not included. I'm sure this will make a big difference, I have to wait until my girlfriend brings my car back to install it.
Hopefully it will be a snug fit.


edit:

I installed this last night and it fits perfectly. I was going to do the DIY filter but we live in a hot environment and I had concerns about the duct tape melting. With having to replace the filter only every 10,000 miles it should be easy to go to NAPA whenever i need one.

Excellent post! Thanks for the info. Wife's '09 Yaris cabin fan was humming. Checked the air filter/fan...No filter & a piece of paper in the fan. Your post saved me an $85 air system diagonostic charge & since the car is still under warranty I will be insistiting on a warranty Toyota cabin filter. Many thanks! DJ

I've had a look around, read this whole thread and it seemed like the best place to ask (if not, correct direction pointing would be welcome!)

I've got a slightly smelly aircon and before I try installing a filter I wanted to spray some antibacterial stuff into the system (Toyota AU wanted $50 for this). It was an effort but I finally found the spray... now I don't know where to spray it. Can someone tell me exactly where the aircon intake is?

Edit: just tried to put some product (turns out it's a foam, not aerosol) in the fan part under the side passenger glove box... well you can't spray a foam upwards so I didn't get any in the aircon. So now we're all out of ideas.

Just wanted to reply that I just did this and it's an excellent write-up. I have a hard time believing this filter would put more strain on the system than a factory one, especially a clogged factory one.

Thanks for the great idea.

Just did this, seems to be working wonderfully. Saved me some money in my pocket :) Thanks!

Going to try this out.

I am pretty sure they fit in only one way, maybe you put it in one of the 3 non correct ways?

Mine came with a small piece of paper with some diagrams.
Showing where it is in the car and how to install it.
Was easier than searching the owners manual or the service manuals that I downloaded.

Here is a vinyl frame I made for my cabin filter.

This frame does away with the one inch cardboard / duct tape border on the Filtrete filters that the OP has on his filter. I used the same Filtrete filter as the OP did. I cut my filter material from inside the borders so I could get as much filter material as possible inside the frame. This frame flexes also to make it easier to get into the cabin filter air box.

I used an 8' piece of vinyl corner bead that I got from Menards. You can get it in the drywall section of the store.

The product is gripSTIK 8' Vinyl Cornerbead. Cost is $1.31. You can make 2 frames with an 8' length.

http://www.menards.com/main/building...171-c-5655.htm

1. Cut the 8' length down to 31-1/4"

2. The bead comes with 1-1/4" legs. Use tin snips to trim one leg down to 7/8" (this will be the sides of the frame).

3. Use tin snips to trim the other leg down to 5/8" (this will be the bottom of the frame).

4. Layout the cuts for the frame. From one end mark the 5/8" leg at 8-1/4", 15-5/8", 23-3/4". (I know these dimensions seem odd, but they take into acount the thickness of the bead so that you end up with a nice rectangular frame).

5. Cut and notch for the frame corners. At each mark you just laid out, cut the 5/8" leg with a straight cut followed by an approx. 45 degree angle cut as shown. Cut a 45 degree angle cut at one end of the bead as well.

6. Fold the bead into a 90 degree angle at each of the cuts.

7. I used electrical tape to tape the open corners together to form a nice rectangular frame. You may need to play around with the notch on the end to be able to get the final corner you tape together to fit nice.

8. The final frame should be 7-5/8" x 8-3/8".

9. Cut a piece of Filtrete filter material to fit nicely into your frame and install into your Yaris. (By the way, My 2010 Toyota Prius takes the same size filter, so it fits that car as well).

10. To seal the frame up a bit better, I also wrapped a layer of electrical tape around the the sides and bottom to seal all of the holes in the corner bead material. Sorry, I didn't get a picture of this. I think this might prevent air from getting around the filter as easy.
