They fit perfectly in my Tetra Whisper PF10. They are a little thicker (a good thing) than the Tetra brand filters indicating that there is more stuff inside them to filter the water. I don't know why Tetra doesn't add zeolite in their filters, especially considering that they are more expensive than these filters are. They are great quality, and a great value, they definitely clean the water because I tested it with a test kit and this filter lowered my nitrate levels, which I was having a problem with.
