Product review (2 stars): flimsy. grows mold quickly.
Compared to the original filter, this filter hasn't the blue outer cover. The white material is very flimsy and easy to break, and the glue that holds the seam together is rigid. This makes the seam very easy to tear up when cleaning. It's still less than a month, I handle it with great care, but the seam has already been teared up no matter what. And mold builds up quickly if you don't clean it every week.
