Our take
The Monterey OB50 with the LONGLAST OB06 filter is a separately documented configuration from the OB03 Standard-filter Monterey already in the finder. Its clearest practical distinction is the longer 120-gallon replacement interval and a broader set of performance-sheet claims. The historical row names a blue pitcher with a LongLast filter, but its Amazon parent, exact finish, size, and package have not been independently established. There is also a meaningful documentation change: Brita's older LONGLAST sheet includes Monterey in a lead-reduction certification footnote, while the current OB06 sheet's specific lead-certification statement leaves OB50 out. Treat lead reduction as unresolved for this exact pitcher/filter combination.
Consider the documented OB50/OB06 family if you want Brita's longer 120-gallon filter interval and will verify the exact pitcher and package before buying. Do not use this profile to satisfy a firm lead-reduction requirement without confirmation from Brita for the exact system..
Do not shortlist this configuration as a confirmed lead-reduction solution, because Brita's current model-specific certification note excludes OB50. It is also not a fit if you require a verified blue finish, exact 10-cup capacity, dishwasher-safe cleaning, or proof of the old listing's included filter count.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Brita's LONGLAST user guide explicitly lists Monterey OB50 with replacement filter OB06.
- The manufacturer gives OB06 a 120-gallon replacement interval, about six months for an average family, and a maximum processing guideline of 2 gallons per day.
- The performance data reports reductions for chlorine and mercury, and the guide describes an indicator mode for the longer-life filter.
What to weigh up
- The current OB06 sheet's separate lead-certification note omits Monterey OB50, although an older LONGLAST sheet included OB50 in its certification footnote; the lead claim is therefore unresolved for this pairing.
- Brita says to hand-wash the pitcher and reservoir and not to put them in a dishwasher.
- The source row's blue finish, historic Amazon parent, exact capacity, and package contents have not been matched to manufacturer documentation.
Specifications and exact model details
The key details
| Model covered | Monterey OB50 pitcher / LONGLAST OB06 filter |
|---|---|
| Model and compatible filter | Brita's LONGLAST guide pairs Monterey pitcher OB50 with OB06; current performance materials call the OB06 filter Elite. |
| Pitcher capacity | The historical row title says 10 cups, but the reviewed manufacturer sources do not verify capacity for that exact listing. |
| Documented filter maintenance | Replace OB06 after 120 gallons (about six months for an average family); Brita advises processing no more than 2 gallons daily. |
| Maintenance monitor | A dual-mode fill-count indicator can be set for LONGLAST; it is not a handheld TDS meter. |
| Care and handling | Hand-wash only; Brita says not to use a dishwasher and gives 85°F as the maximum water temperature. |
| Documented reduction and certification scope | The current OB06 sheet reports chlorine, mercury, and other listed reductions but its lead-certification note omits OB50; lead remains unresolved against the older footnote. |

Full review: how the features affect your choice
What the features mean for you
Keep the two Monterey filter versions distinct
Brita's LONGLAST guide names Monterey model OB50 with filter OB06. That is a different documented configuration from Monterey OB50 with the OB03 Standard filter, and the two filters have different replacement schedules and performance sheets. The source row 25 calls the item blue and says it included LongLast, but the row's historical Amazon parent does not establish its exact size, color, or package. I use the official OB50/OB06 pairing to describe the model family and leave those listing details open. Check the model labels and included filter on the package before relying on this profile for a particular variant.
Read the performance claims as a model-specific set
Brita's current OB06 performance sheet reports 97.4% chlorine reduction under its stated test conditions and reduction data for mercury and other listed substances. The sheet's top-level covered-system list includes Monterey OB50, but its separate note for certified lead reduction names several other pitchers and omits OB50. An older LONGLAST guide lists Monterey in a broader certification footnote that includes lead. Since the current manufacturer material is not consistent with the older note on this point, this profile leaves the lead attribute unknown. Standards and laboratory claims cover only the named substances and conditions; they are not a general promise to make unsafe or unknown water potable.
A six-month target is still a use-dependent schedule
Brita recommends replacing OB06 after 120 gallons, about six months for an average family, and says to process no more than 2 gallons daily for maximum efficiency. The guide describes a dual-mode indicator: reset it when replacing the filter and select the LONGLAST setting for the 120-gallon interval. Its fill counter is a reminder, not a measurement of contaminant concentration or proof that the filter is still performing. People who use more water, have different source-water conditions, or need a guaranteed service interval should follow the package instructions and Brita's current guidance for their exact pitcher.
Plan for hand-washing and cold water
Brita's LONGLAST guide says to wash the pitcher, lid, and reservoir periodically with mild detergent, rinse well, and avoid dishwashers and abrasive cleaners. It gives the OB06 a maximum water temperature of 85°F, so this is a cold-water pitcher filter rather than a way to treat hot water. The care instructions are simple but are a real trade-off if your normal routine depends on dishwasher cleaning. Brita also says not to use its filter for microbiologically unsafe or unknown-quality water unless adequate disinfection is provided before or after filtration.
Decide whether its documented strengths match your priorities
The strongest documented reasons to consider the OB50/OB06 family are the longer replacement interval, chlorine reduction, and a broad performance-data sheet. It may fit a household that wants fewer filter changes than the OB03 Standard version and is comfortable with a fill-count reminder and hand-washing. It is not the right choice for a buyer who must have a confirmed lead claim, a verified capacity threshold, or a proven Amazon bundle. The old listing's color, parent, and exact configuration remain open, so use the tagged exact-model search only as a way to look for the matching product and inspect its label and contents before purchase.

Before you buy
Which filter model is documented for the Monterey?
Brita's LONGLAST guide lists the Monterey as pitcher model OB50 paired with filter OB06. Brita now uses Elite for the OB06 filter in its current performance materials, while older manuals and listings use LONGLAST or LONGLAST+. Check the filter code on the actual package.
Can I count on this Monterey configuration to reduce lead?
Not from the current evidence for this exact pairing. An older LONGLAST sheet included Monterey in a certification footnote, but Brita's current OB06 sheet names other pitcher models in its specific lead-certification note and omits OB50. This review therefore leaves lead reduction unresolved.
How often should the OB06 be replaced?
Brita recommends every 120 gallons, about six months for an average family, and no more than 2 gallons of processing per day for maximum efficiency. Actual use and local water conditions can change the practical schedule.
