Just not right.
Color: Blue
Well this is a crazy situation it says it fit my car so I bought it think it was different from any others so I tried it. It DOES NOT fit a 2008 impala. It is not wide enough one way but to deep the other, even if rotated. I even tried over and over but it did work.

Bad fit and bad information
Color: Blue
When I purchased this, it said it fit my 2007 Toyota Prius. Not even close. The problem with the smaller item purchases, is you end up giving the company money and it’s just not worth my effort to re-bag it, and find where I would need to return it. I would be extremely cautious if purchasing from this company.

Smells fresh!
Color: Blue
This filter does a great job of keeping my truck AC smelling fresh. It has a bit of a chemical smell the first day or so but clears up nice
