This is not a like for like replacement for K201. After removing the old one and screwing the new filter on, the new leaked all over my cabinet. I removed it a couple of times to ensure the seal was clean and it did not matter as the new filter kept a constant drip . Wayfair customer service was excellent and contacted me quickly and gave me a full refund as the filter was defective.
