I don't know about that particular air filter but I can tell you that they do work, well, a good one that is. I have two air purifiers in my home with ionizers. They help with odors.after just one day of running them the air was so much better. The one you are talking about has a lifetime filter, which is nice, because the ones I have the filters that have to be replaced and they are not cheap. But it is amazing to pull the filter out and see all of the crud that was in the air.
