Yea a hepa will be the same as the lexus... bascially it filters the outside air before it enters the car. Stock its just a straight pass no filter so your getting the outside air inside along with dust, leaves etc.

 

This is kinda an obvious question but its questionable haha

Does this filter only work when you have the A/C on or does it just work all the time

 

All the time

 

Just pulled it out....a bunch of dust and nothin else?? I'm guessin there should be a tray for this right?

If i don't have a tray, is there a way to make one?

 

The tray is part of the new filter

 

I think i'm gonna get a hepa filter from home depot and make one myself. How do you make a tray so it fits snug in there and doesnt pass up any dust particles. (besides the obvious of getting a oem one)

 

Anyone know how to make a filter if you don't have the tray for it? A hepa filter

I can't understand why you actually make your own, but have at it. I just did a google search and bought the cheapest one I could find, either way, it was less than $50. I'm not gonna cry over that....

 

Spray fabreez on it and it will always smell fresh in your Ride!
