Title: NOISY - is this thing diesel-powered?
Review: I have never heard a more noisy filter. In the roughly one year since I bought it new, I've observed that it has basically has 2 impeller modes - noisy and more noisy. For no apparent reason it just kicks up the volume at random times, often during my favorite TV shows. I'll never buy another filter made by these folks.
Is the review positive or negative?
