This is a high quality filter. Kohler makes a number of identical-looking filters numbered K-201, K-202, K-203. The K-203 had been discontinued. The difference between the K-202 and the far less expensive K-201 is Lead filtering and flow rate. The K-202 has Lead filtering and a .6 flow rate whereas the less expensive K-201 has no Lead filtering and a 1.5 Flow rate. The K-202 has recently experienced a very steep price increase. (67% since last year!)
