My goal of this window film is to eliminate reflection. Will this film achieve that goal? Also, is it removable? (This Is only a seasonal need).

I recommend you request some free samples to see if it will do what you are wanting. Yes, all of the films are removable, but the adhesive films are not reusable like the static cling. This one may leave a slight glue residue when removed, but it can be removed with soapy water and a razor blade.
