Review on 2 Pack Fresh Flow Filters - Optimize SEO by Jessica Parks

I bought this for my cat's pet cat in hopes of filtering water and making it taste better. I was disappointed. It didn't take long and the filter (which I understand is made of charcoal) is leaving small pieces at the bottom of the fountain even after I've flushed it multiple times. So yes, sometimes the water looks dirty! You get what you pay for, it was cheap and I should have known. I'm giving it one star because it ran for a while but not overly impressed with the performance.
