Ametek CCF-201

I have just moved into an apartment and the unit has a water filter system mounted beneath the kitchen sink with a faucet on top.
The brand is Ametek and the mounting bracket has a logo which reads “Water-Safe” in blue script. I don’t know how long the filters have been in use, but I would like to change them.
There is no model number.
The filter system has two housings – one reads “pre-filter” and the other “post-filter” and they are about 10” in length and 3 1/2″ round. It looks like the Ametek 10 inch displayed online, but I don’t know.
Can you help me?

It seems to be the CCF-201.
This is described in a previous post.
