Miele has a carbon filter attached to a paper filter while VEVA3 only has a paper filter. What does that mean? Well, the activated carbon filter is very good at neutralizing odors, so this element has completely disappeared. You only have one filter area. I'll probably skip these as it's an important feature for people who have pets etc. Note that in the first photo the Miele is on the left and the VEVA3 is on the right. Second photo of Miele (see activated carbon filter section) and VEVA3 on the right.
