I give them five because they were great filters. BUT I have to say that the last two filters of my last order were clogged in the two small drainage holes at the bottom. I had to put a needle in the holes to clear the blockage for them to work. It's more of a headache than anything. I won't stop buying them until it gets into the habit of cleaning holes.
