What a mess!  The charcoal gets over everything!  I don't understand why the packaging of this product is so poor.  The other items in my order where covered with this mess.  For example, I had ordered a 6 pack of tempera paints for my granddaughter.  Not only was the outside package covered with charcoal dust, but each individual jar inside the little box was covered and I spent a lot of time cleaning each jar and had to throw out the box the paint jars came in.  I also accidently ordered the wrong size cartridge (the smaller size I get is individually packaged in plastic and does not have this mess problem).  Rather than send it back, I just threw this out as well as the larger box it came in since it was also covered in dust.  My husband ordered the right size for our filter and those work well.  So if you need this size, order it by itself because it may ruin other items in your order.
