The filter can be placed into the machine different ways not just one way

I was puzzled by this too, but when I went to replace it after a month, Walmart didn't have that certain number, but a got another of a different number similar to it, and I can turn it either way inside the unit and it worked.

It fits both ways but works best and is easy to clean with each fill when the firm side is to the back of the machine and the softer side to the front of the machine.
