How to use "how long" with "for"?

I found the following sentence in a video. I would really appreciate it if someone could explain why they have used "for" at the end of the sentence. I mean, according to my knowledge, regardless of the existence of "for" the meaning of the sentence remains intact. Furthermore, could someone please let me know the grammar points associated with this as well. This is mainly attributed to the fact that if I knew the name of the grammar related to this, I could search it on the internet and find more articles to learn about this more.
