Hi Jackie, as it turns out I'm looking for the exact same products as you are for the exact same model vacuum cleaner. After doing a bit of research, it appears that this kit is going to be the best replacement solution for both of us. I'm not sure if ezvacuum offers this exact kit but based on what I'm seeing it looks like this kit is compatible with the NV46 model. Hope this helps!
