"The commercial housing works as described but I wished it would come with the mounting brackets and screws because I initially bought the wrong ones."
— Stephane R. (4/5)
"Housing is fine - good quality, but the mounting bracket sold does not fit without modification. This problem has shown up in your comments but has not been corrected - why?"
— Dan K. (3/5)
"Why don’t they come with a wrench anymore. Good thing I have some otherwise client would have been oissed"
— Todd M. (3/5)
"Fast delivery as promised."

"Thank you for extra strong packaging-everything arrived in perfect condition."
— Michael B. (5/5)
"This filter is working great. The installation was a bit tricky, since it is hard piped in. I had the bypass pipes on the wall from a previous filter. I still have an intermittent leak between the base and the screw-on housing, which I believe is because I have to stress the pipe connections to connect it. The base is likely being flexed. Other than this, which would be my fault, not a defect, I am very happy. Tech support has been superb."
