TapBuff searched the certifiers’ own listings and found nothing for this product. That does not mean it does not work. It means no independent certifier has confirmed what it reduces, so every claim below is the maker’s alone.

Nothing.

Claimed by the maker only

  • Reduces chlorine, chloramines, lead, pharmaceuticals and other contaminants (Bosch, Thermador and Gaggenau store pages).

Certification claims we could not find on a listing

  • Bosch says the filter received NSF certification; no NSF, WQA or IAPMO listing names 11032531, BORPLFTR50 or BORPLFTR55 as of Oct. 9, 2026. NSF lists Bosch refrigerator filters only under internal numbers that no Bosch page ties to this one.

What it costs over five years

Replaced on the maker’s interval, the schedule the fridge’s own filter light keeps, at list price. Every filter is counted: the one that came with the fridge is long gone.

Where these lists come from

Worth knowing

The same filter, part 11032531, is sold as Bosch BORPLFTR55, Thermador REPLFLTR55 and Gaggenau RA450055. Bosch publishes no gallon rating; replace it every six months or when the fridge says to. The list of models comes from each current refrigerator’s own page, so older models are missing.
