It's a lower cost, easy-fit swap for Bosch's OEM filter that handles taste and chlorine fine, but it isn't the certified match for lead, mercury or cyst reduction the genuine filter provides.

Overview
Bosch's 11025825 UltraClarity Pro filter (BORPLFTR50) gets a lower cost replacement here, sized to fit 800 series French door refrigerators and other listed Bosch and Thermador models.
Bosch's OEM UltraClarity Pro filter is certified for lead, mercury and cyst reduction on top of taste and odor; this replacement's own product statement discloses it is NSF 42 certified only, covering taste, odor and chlorine. That's a meaningful gap for anyone buying it purely to match OEM performance rather than just to save money.
- Replaces Bosch 11025825 / BORPLFTR50
- Activated carbon block filtration
- 6 month or 200 gallon rated life
- Fits KWF 2000 and 800 series models
Who it's for
Bosch and Thermador fridge owners with relatively clean source water who want a cheaper cartridge for routine taste and odor filtering. Not the right choice for anyone specifically relying on filtration for lead or mercury reduction.
What buyers say
From Amazon customer reviews.
Buyers with Bosch 800 series and Thermador fridges reported it installed without leaks, tasted the same as the OEM filter, and cost noticeably less. One detailed critical review pointed out it is only NSF 42 certified for taste and odor, unlike the Bosch original which also carries NSF 53 and 401 certifications for lead, mercury and other contaminants.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fits Bosch 800 series without leaks
- Noticeably cheaper than the OEM cartridge
- Easy tool-free install per reviewers
- Preserves mineral content in filtered water
- Only NSF 42 certified, not NSF 53 like OEM
- Water flow inconsistent for some users
- Still costs more than basic generic filters
Performance notes
An activated carbon block is rated to NSF 42 standards, targeting chlorine, taste and odor while the listing states it preserves beneficial minerals in the water. It is not rated to NSF 53, the standard covering lead, mercury and cyst reduction, which the genuine Bosch OEM filter carries in addition to NSF 42.
