Please correct me if I am wrong but do you think that only zeovit sell zeolite??? Because if so then its not true. AF also sell zeolite. A lot of people think that zeovit only sells zeolite but thats not true. Zeolite are microporous aluminosilicate minerals used as adsorbent and catalyst. It has nothing to do with zeovit.
My only use these days for Zeolites from any source is to simply use to help keep my sons room from smelling like pre-teen boy, they tend to have a butt, pee, and armpit smell rolled into one, I place in bowl under his night stand. It does wonders at removing odors
