What is difference between 0.45 and 0.22 micron filter?

The 0.45 um filter cost less, than 0.22 um, and there is less pressure drop to overcome. However, the 0.22 um filters are good for completely sterile samples, as the cutoff for for biological organisms near the 0.45 um cutoff.

What does 0.1 micron water filter remove?
