Product review (5 stars): awesome venr
This is great! It was a little big for my mobile home vent,so i sawed about an inch off,than slide the cut off piece back onto the vent and taped it w/gorilla tape and it works fine,no leaks. I even put aroma therapy oil into thw water and it smells great. What a difference.no  more static shock and so much easier for me and my cats to breath. Wish I knew of this long ago
