The water is pushed through a filter with suspended carbon particles in it, which some of the contaminants do get trapped within the carbon pores, but most just bypass the filter without ever touching the carbon itself. Hence, a need for a 3rd stage carbon block filter to really trapped the contaminants.

The Chebyshev filter has a steeper roll-off than the Butterworth filter. But it consists of ripples in the passband (type-1) or stopband (type-2). Type-1 Chebyshev filter is commonly used and sometimes it is known as only "Chebyshev filter". Type-2 filter is also known as "Inverse Chebyshev filter".

So, different size filters are used in sequence to reduce the load on a single small-sized filter. The first filter has a 0.45 µm size followed by 0.22 µm. Later, they get sterilized with steam for another batch process. These filters require filter integrity testing both before and after use if tested non-destructively.
