Package was new; however, once installed, the smell was horrendous. It smelled like the filter was used in a fire. It had a VERY strong musty/burnt odor to it. I was going to return it, but it would've been difficult since it was already wet (and I would've had to wait another 2 days). The only solution we had was to soak it in bleach for a few hours and then rinse it out. I would NOT recommend this product.
