They look the same as other brands of filters I've had before but the shape is much better. Other brands I've bought in the past to save money were brown and crappy after a week. Also, I can't say anything actually bypasses that filter because I have 1 micron behind that 5 micron. The 1 micron filter is still white and looks like new. This first filter I installed lasted maybe almost two months and was just starting to discolor. Gets a 5th star if it takes up to 6 months. The only thing I didn't like was that it was about 1/8 inch longer. It must be 9" and 7/8" to fit standard size cases. With a little extra effort, I was able to pull the case down, slide it in, and seal the leak.
