just received this today. i immediately unboxed it and see what's inside. this is what i found. 1. the item has 2 charcoal filter but it has no central filter inside. good that i have bought a separate filters already. to the supplier do not short-change your clients. just send the white cylindrical filter right away or you will face legal complaints about it. thank you.
