These filters fit perfectly and are easy to replace. The instructions were a little confusing as to which filter to put in first. Specifying 1st and 2nd would be better than specifying right and left in my opinion, since right/left depends on how it's set, and the color-coding of the filters just adds to the confusion. Labeling the filter function would be better. But is it a manufacturer's problem, not a retailer's? Figuring out which filter to put in first took longer than installing.
