Review: Used with an Abode Aquifier tap, and better than the manufacturer's original cartridge - As part of a recent kitchen refurb we had an Abode Aquifier filtered water selector installed (you use your normal kitchen tap, but when you want filtered drinking water you twist a knob alongside your tap to route the water flow via a filter). We were disappointed from day one, the filtered water was never as good as we used to get from our old Brita water filter jug. We tried severely restricting the flow through the filter, so that just a dribble of filtered water came out (slower flow/better filtration was suggested by the Abode instructions). We tried flushing for 20-30 seconds each time before actually taking water to make drinks. All to no avail. We wondered whether we might need Abode's high-resin for the hardest water areas filter (£50 each!). Bought one of these, instantly fixed! Great tasting tea again :) No need to rinse/flush first. No need to restrict the flow. AND half the price of the original filter! Happy with that - it now performs as we had hoped. Review: All Good! - All perfect,,,,usual quality, good price and very fast shipping...100% recommended! ## Features - Warning:Only for domestic use - Size: 6.4cm x 6.4cm x 21cm - For Bosch, Siemens, Neff Refrigerators - Internal water filter cartridge for side-by-side refrigerated freezer combinations - easy to use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002GBYVAQ | | Benefits | Removes Odor | | Best Sellers Rank | 133,448 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 99 in Fridge Water Filters | | Brand | Cuno | | Brand Name | Cuno | | Country Of Origin | USA | | Customer Reviews | 4.5 out of 5 stars 482 Reviews | | External Testing Certification | ANSI, NSF | | External testing certification | ANSI, NSF | | Global Trade Identification Number | 00016145068805, 00051128890714 | | Item Dimensions D x W x H | 6.4D x 6.4W x 21H centimetres | | Item Weight | 313 g | | Item weight | 313 g | | Manufacturer | Commercial Water Distributing | | Manufacturer Part Number | CS-52 3M | | Material | Activated Carbon , Resins, Ion Exchange Materials | | Material Type | Activated Carbon, Resins, Ion Exchange Materials | | Model Number | CS-52 | | Number of Items | 1 | | Product benefits | Removes Odor | | Product dimensions | 6.4D x 6.4W x 21H centimetres | | Set Name | Single Unit | | UPC | 163120791552 806294984015 887701678130 095225175909 016145068805 809390002942 700999870768 115971036498 887701728217 846829445338 051128890714 807032972264 | | Unit Count | 1.0 count | ## Product Details - **External testing certification:** ANSI, NSF - **Item weight:** 0.69 Pounds - **Material:** Activated Carbon, Resins, Ion Exchange Materials - **Product benefits:** Removes Odor - **Product dimensions:** 6.4D x 6.4W x 21H centimetres ## Images ![3M CS-52 Cuno Bosch Siemens Neff LG Water Filter, 6.4cm x 6.4cm x 21cm - Image 1](https://m.media-amazon.com/images/I/71nQG0JhJmL.jpg) ## Questions & Answers **Q: when does this product need to be replaces?** A: Depends on your water flow/usage, we (family of three) get about six weeks before we need to replace this filter, which is fitted inline to our kitchen cold water tap (NB we're in a very hard water area).Hope that helps ... **Q: Is this suitable for a bosch kad62s20 american fridge freezer?** A: Hi, Information to hand indicates this is not the correct water filter and you require an UltraClarity Search for ' Bosch Fridge Freezer Model KAD62S20 fridge water filter cartridge ' on Amazon.In addition remove your existing water filter to make a photo match with the the photos supplied - Regards, Peter **Q: Any idea where to dispose of old water filters** A: I put mine the our recycle dustbin **Q: Is this suitable for an American style Fridge Freezer (bosch model KAN58A45G)?
