Going the mikva

To toivel (immerse) some glasses that I bought and my new aluminum water bottle. The mikva is a holy place. In Berkeley, it is behind a house that a Chabad couple lives in, the husband runs the Vaad HaKasrus for N. California. A mikva is a little bit like a hot tub, there was a cover over the water. I didn't remove the whole cover. I put my items in a basket. said the blessing blessed are you... who immerses vessels. Its not about making them kosher, if I understand, its taking ownership of my vessels. I feel like I did a purifying mitzvah for the day.
