Product review (5 stars): Soak your filter first
I recommend you soak it in water before installing. I did it the hard way and it wouldnt work. Once I soaked the filter it started right away. Then I had to figure out how to remove the change filter status. But I googled and held down the light and lock buttons for 3 seconds and it was gone. I love that I can get 3 filters for the price of what the manufacturer would charge you.
