I have included a lot of pictures of the actual unit and a lot of pictures from the manufacturer's listing that gives a lot of good information please look at them all.

This is a used unit in great condition and works perfect. As you can see it needs a new set of filter elements which are about 60 bucks as shown in the pictures.

As you can also see from the pictures this is a $500 retail filter. That's not some BS suggested retail that's a real price.

These are an excellent filter.
