The first problem was the packaging and shipping, the filters weren't properly protected and four of them were out of shape so I remade them as best I could. The second issue is that these filters are treated with baking soda to eliminate odors, and while they appear to help control odors, unfortunately the baking soda releases an unusual amount of white dust that collects on all surfaces very quickly. Using these filters makes me dust my house every day! After switching to a non-soda filter, the dust problem went away.
