Product review (5 stars): This is the exact filter that came with the fridge
This Bosch 9000 077104 UltraClarity is the correct filter replacement for Thermador T36BT820NS. It is not much cheaper than buying it directly from Thermador or Bosch, but at least it came in one day with Prime. I tried getting a less expensive ($15) "replacement" that claimed to be the exact filter model number before buying this one; the cheaper one looked similar, but it kept popping out once twisted in. If you buy this one, at least you know it will work for sure. To reset display for this model fridge after installing, press and hold Super>>Cool and Ice buttons simultaneously for 3 seconds.
