Easy as plug and play
I bought this to replace an ionizer going out. I was looking for something that did not require a filter. ✅  Quiet ✅<br />This unit was a direct plug in to the wall unlike my other which was a corded unit.  But I love the direct plug into the wall and a plus is the ultraviolet light, which makes me feel safe with the idea of Corona viruses in the air. If you are sensitive to light and sound after the lights go out for the night, I move it out of the bedroom overnight into another room. So at least each room is getting a 12 hour coverage. I live in a very small place. I liked it so much I bought another for our trailer.  In case you are wondering, I didn't review for odors because that wasn't a reason I bought this unit. We don't have an odor problem so I don't notice a difference in regards to odor elimination. I feel that this unit was reasonably priced and affordable if you have a tight budget.
