Fortunately I have kept the old instructions included in earlier packages. I was nervous about installing this, but it was the old one was easy to remove and the new one was easy to install.1 May26 I ordered another filter, and received a package which showed only that it was for Bosch Thermador. After much searching and asking the Rufus AI, I learned that this filter should work.But, I search on the Bosch

Something about the flavor of the water from this filter. It is great.
Fit and function is very good. A little expensive, but I wanted to replace filters that are designed for the Thermador freezer.
I searched for a lower priced filter and found another outlet selling 2 filters for the price of one at Amazon. After receiving and installing one, the the water dispenser wouldn't work. Took it out and compared the top to the old filter to see it had different holes. Even though the Bosch item number was on the box stating it was comparable, it was not and had to order from Amazon in the end.
Super frustrating! Ordered two for a Thermador Freezer but neither work - there’s no rush of water into filter when installed. Outside the return window so it’s an expensive lesson. Reinstalled the old filter which looks identical but still works. I’ve tried other brands that say they are compatible but they typically don’t work well which either have no/low water flow or they leak water into the tray & create an ice block.Ordered a new filter through Thermador which is very expensive but at least they work.
Despite the negative reviews I bought it anyways. It is the same brand and model # as my old one.NEW (Left) Old (right)The Bosch - UltraClarity filter replacement fit my Thermador T36BT920NS. This is the first time replacing the filter since we got the fridge.Both filter and box it came in says it’s Made in the US by 3M. A recent review said it could be counterfeit, the print is bolder but the address /information matches my old filter that’s came with the fridge. So next time it needs replacing I’ll spend the extra $$ and buy it straight from the website. I’ll see for myself and compare it to
Works as described , the water taste better with the filer on
Installing the filter was easy. The only issue I experienced was something in the instruction sheet that I couldn't figure out. The instructions called for cleansing the filter by letting water run through it before activating the ice maker. Well, I look at my setup and could not find anyway to flush the filter without extracting my built-in from its enclosure - a very work-intensive undertaking. So I skipped the flushing step and tossed out the first six batches of ice in hopes the filter would be cleansed by then.
