Product review (3 stars): Saves your main whole-house filter from premature clogging.
I installed this 250 mesh (61-micron) as a prefilter to my 5-micron whole-house filter. I immediately was able to see it collecting sediment that would have prematurely clogged the main house filter . One quick flushing and the Rusco was clean again.

P.S. After several more weeks, I found that the Rusco Filter was clogging up too often - sometimes several times a day. That's partly due to the amount of sediment in my water. However, much of the problem is due to the small capacity of the Rusco screen. They should make that filter much larger. Rusco also makes a sediment filter with a small trap on the bottom - to allow for the accumulation of excess particles. Unfortunately, after researching this alternative filter, I couldn't find it other than in a course 100 mesh. The Rusco Spin Down I currently am using has a  much finer 250 mesh.
Note: I've called Rusco on at least 2 occasions. The first time, the person who answered knew about their products and was very helpful. The second time I contacted Rusco, the gal that I spoke with knew less than I did about their products and was rude.
