Bosch BORPLFTR50 UltraClarity Pro Water Filter

Bosch BORPLFTR50 UltraClarity Pro Water Filter Replacement

The BORPLFTR50 is Bosch’s UltraClarity Pro — the top refrigerator water cartridge in the Bosch range — built for Bosch Benchmark and Thermador fresh-food columns and French-door models. If your refrigerator specifies the UltraClarity Pro cartridge, this is its replacement: the same cartridge your fridge was supplied with, renewed. Its filtration reduces chlorine taste and odour, sediment and a wide range of common contaminants, so the water from your dispenser and the ice in your freezer taste the way they should — like nothing at all. One cartridge lasts about 6 months, and it changes in minutes: push, turn, done, with no tools and no water shut-off on most models.

A premium refrigerator deserves water to match. Bosch and Thermador columns are bought for precise cooling and clean design, but the glass of water from the door is only as good as the cartridge behind it. When that cartridge is exhausted, the signs creep in quietly: a chlorine tang in the first glass of the morning, ice that makes good drinks taste faintly of the freezer, a dispenser stream that slows to a dribble. The BORPLFTR50 is the fix the manufacturer intended — the genuine-specification UltraClarity Pro cartridge, swapped in minutes, good for another six months.

Why Choose the Bosch BORPLFTR50

The UltraClarity Pro is the cartridge Bosch fits to its flagship refrigeration — the Benchmark series and Thermador fresh-food columns — and that positioning matters when you are choosing a replacement. Cartridges are machined for specific housings: only the correct cartridge seats fully, seals against the housing and routes every drop of water through the filter media. A near-fit can pass water around the media instead of through it, which means the dispenser works, the light resets, and nothing is actually being filtered. The BORPLFTR50 removes that gamble. It is the specified cartridge for refrigerators that call for the UltraClarity Pro, it replaces the older RA17345 part number, and it goes in exactly the way the original came out.

Owners also choose it for what it does to the water. Chlorine — necessary in the supply network, unwelcome in a glass — is the chief cause of taste and odour complaints, and sediment is what turns ice cloudy and leaves grit in the bottom of a jug. The UltraClarity Pro’s filtration works on both, along with a wide range of other common contaminants, so water tastes clean, ice freezes clear, and coffee and drinks made with dispenser water taste of what you put in them, not of the journey the water took to reach you. One cartridge, roughly every 6 months, changed by hand: that is the whole maintenance commitment.

Compatible Refrigerator Brands

The BORPLFTR50 fits Bosch and Thermador refrigerators that specify the UltraClarity Pro cartridge. The surest identification is never the badge on the door — it is the label on the cartridge already in your fridge. If that label reads BORPLFTR50, or the older RA17345 number this cartridge replaces, this is your filter.

Bosch Refrigerators

Many Bosch French-door and Benchmark models use the UltraClarity Pro cartridge. If your Bosch refrigerator’s manual or existing cartridge names the BORPLFTR50 (or RA17345), this replacement restores the filtration the appliance was designed around.

Thermador Refrigerators

Thermador fresh-food columns that specify the UltraClarity Pro cartridge take this same filter. Check the label on your current cartridge: if it reads BORPLFTR50 or RA17345, the BORPLFTR50 is the correct renewal for your column.

Replaces RA17345

Bosch lists this cartridge as the replacement for part number RA17345 as well as for BORPLFTR50 itself. If your manual, your appliance paperwork or the cartridge in your hand shows RA17345, order the BORPLFTR50 with confidence — it is the current cartridge for that specification. And if your fridge takes the standard UltraClarity cartridge instead (BORPLFTR30), that is a different filter for a different housing — match the label, every time, before you order.

What the UltraClarity Pro Reduces — and How It Works

Every glass from the dispenser and every batch of ice passes through this cartridge first. As water flows through the UltraClarity Pro’s filter media, chlorine taste and odour are reduced at the source, sediment particles are trapped before they can reach your glass or cloud your ice, and a wide range of other common contaminants carried in household water are reduced along the way. The water that reaches the dispenser is simply cleaner: neutral-tasting in a glass, invisible in cooking, and clear in ice.

There is a system-protection side to this as well. Sediment that never reaches the dispenser and ice maker is sediment that never builds up in their valves and lines. A fresh cartridge also keeps the flow strong: as any cartridge loads up over its life, the stream from the dispenser slows, and that slowing is often the first mechanical sign that the change date has arrived. Replacing the BORPLFTR50 on its six-month rhythm keeps taste, clarity and flow where a Bosch or Thermador appliance is supposed to deliver them.

Fresh Water for Everyday Use

Refrigerator water is used more than almost any other water in the house: drinking glasses through the day, bottles filled for work, school and the gym, ice for drinks and coolers, water for coffee machines and kettles, rinsing fruit, soaking ingredients. One cartridge stands behind all of it. That is why a fresh UltraClarity Pro makes a difference you notice immediately and then stop noticing — water goes back to being a neutral ingredient in everything. Families who entertain notice it in ice most of all: clear cubes that melt without adding a flavour of their own to a drink someone took care over.

Easy to Replace — Step by Step

The BORPLFTR50 changes in minutes, by hand, with nothing more than a glass or jug for flushing:

1. Locate the filter compartment in your refrigerator (check your manual if you have never opened it — placement varies by model) and have a small towel handy for the few drips that are normal when a cartridge comes out.
2. Remove the old cartridge following the release direction shown on the compartment — on most models it is a push-and-turn or pull release. Steady pressure, no force.
3. Read the old cartridge’s label as it comes out — BORPLFTR50 or RA17345 confirms you have the right replacement in hand.
4. Push the new BORPLFTR50 into the housing and turn it until it locks firmly. A cartridge that is not fully locked is the usual cause of drips or a dispenser that will not run after a change.
5. Flush about 2 gallons through the dispenser (next section) and discard that water plus the first batch of ice.
6. Reset the filter indicator on your refrigerator (below), and note the date. This cartridge is due again in about 6 months.

Flushing and Resetting the Filter Indicator

Flushing is not optional. A new cartridge holds loose media particles and trapped air, so run about 2 gallons of water through the dispenser and throw that water away — it is ideal for plants or cleaning. The first ice batch goes too: cubes made during the first fill can carry the same residue. After the flush, the water should run clear, steady and taste-free, and the dispenser may splutter briefly as air clears the line — that is normal and stops on its own.

Then reset the indicator so the fridge counts the new cartridge’s life from today. The reset method varies by model — many Bosch models use a filter reset control or a press-and-hold on the display panel — so follow the sequence in your manual. Two rules apply to every model: fit the new cartridge before you reset (a reset tells the fridge a fresh filter is in; it does not make an old one fresh), and if the light comes straight back on after a correct change, check the cartridge is fully locked before suspecting the appliance.

When to Replace Your BORPLFTR50

One cartridge lasts about 6 months. Replace it sooner if the symptoms of a tired cartridge arrive first: chlorine taste or odour returning, ice turning cloudy or hollow, the dispenser stream thinning. Those signs outrank the calendar, and heavy use — a large household, an ice maker working hard through summer — can bring the change point forward. What never helps is stretching a cartridge to a year because water still comes out: a saturated cartridge keeps passing water while quietly stopping the capture work it exists to do.

Pack Sizes and Value

The BORPLFTR50 is sold in four pack sizes. Every order ships free anywhere in the US — there is no minimum spend, so even a single cartridge arrives with no delivery charge:

A single cartridge at $42.99 works out to roughly $7 a month for filtered water and ice from a flagship refrigerator. The 2-Pack, at $83.99, is less than two singles bought separately ($85.98) and puts a full year of filtration in the cupboard in one order — the next change is on hand the day the indicator lights, so the fridge never runs overdue while you wait for a delivery. The 3-Pack covers about 18 months, and the 4-Pack is the longest horizon: four cartridges, roughly two years of changes handled in a single purchase, one less thing to think about until the following year.

A Reliable Choice for Bosch and Thermador Owners

If your refrigerator specifies the UltraClarity Pro, the BORPLFTR50 is not one option among many — it is the cartridge the appliance was built around, carrying the same specification as the filter it replaces, including the older RA17345 number. Keep its six-month rhythm and the water from a premium refrigerator tastes the way the appliance promised it would: clean, clear and entirely unremarkable, glass after glass.
