Central Air install question/HEPA filter

So we're getting a new unit put in with new ductwork (no existing) and the return is going to go over the stairwell. Being this is a hard to access area (need a tall ladder to reach) for filter changes, i was told they could place the filters (?) in the attic at the air handler. WIth that , i was told that i could also purchase a HEPA filter ($375) to add to the air handler. My thought was that we could buy those disposable HEPA type filters that go at the return grill.

So basically, my questions are:
1-Is it better to keep the filters at the return duct or is it ok to place them at the end of the return duct (at the air handler)?
and
2-Is it worthwhile to get the HEPA filter unit or can i get the same results with just the HEPA disposables?

THanks for the help

return grille sizing is different than standard return sizing and can cause issues with noise and velocity

You can not put a HEPA filter on a residential system unless its a bypass type. 2nd a HEPA system will have it's own blower so there is no way you can get this that cheap. The filter will cost you 200. There is no such thing as a disposable heap filter. I'd go with a filtered return air grill.
