Our take
Clear2O's Mineral Rich Alkaline family has enough manufacturer documentation to identify a real pitcher and its replacement-filter system. The archived catalog labels the pitcher CAP350-BL, while the current CAF301 page says that five-stage cartridge fits CAP350BL and has an 80-gallon target. Clear2O describes coconut carbon, tourmaline, mineral media, and a final membrane, along with a fill window and a volume-based indicator in its launch material. These are useful family-level details, but they do not authenticate the historic blue Amazon listing or its parent ASIN. The reviewed material also lacks a performance data sheet, certification listing, and basic vessel measurements, so the review keeps those comparison fields open.
Consider the documented CAP350-BL family if you want an alkaline/mineral pitcher and can verify the pitcher and CAF301 cartridge on the package. Do not select it for a hard certified-contaminant requirement or assume it matches the historic blue Amazon listing..
Do not rely on this evidence to meet a hard NSF certification, numeric lead or mercury reduction, or exact capacity requirement. Clear2O describes those materials and reductions in product copy but does not publish a model-specific performance sheet in the sources reviewed. This family is also a poor fit if the old blue Amazon parent must be authenticated, or if you need confirmed dimensions, dishwasher instructions, or a stated maximum water temperature before buying.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Clear2O identifies the CAP350-BL pitcher family and a five-stage CAF301 replacement filter that the maker says fits CAP350BL.
- The current replacement-filter page gives a clear 80-gallon target and describes the carbon, tourmaline, mineral, and membrane stages.
- The manufacturer launch material describes a fill window and a volume-based filter-life indicator, which are more specific than a calendar-only reminder.
What to weigh up
- The historical blue listing and Amazon ASIN B00V5DNZY4 are not mapped to the documented CAP350-BL family.
- The reviewed manufacturer pages do not provide numeric contaminant performance data or NSF/ANSI certification for the five-stage cartridge.
- Pitcher capacity, dimensions, dishwasher care, maximum water temperature, and a monthly replacement estimate are not established by the reviewed sources.
Specifications and exact model details
The key details
| Model covered | CAP350-BL pitcher with CAF301 five-stage filter |
|---|---|
| Model and compatible filter | CAP350-BL Mineral Rich Alkaline Pitcher family; Clear2O lists replacement filter CAF301 as compatible with CAP350BL. |
| Pitcher capacity | The reviewed manufacturer sources do not establish the pitcher’s total or filtered-water capacity; the historical listing capacity remains unverified. |
| Documented filter maintenance | Clear2O gives CAF301 an 80-gallon replacement target; this is a manufacturer target, not a separately documented certified claim capacity. |
| Maintenance monitor | Clear2O launch material describes a water-volume-based filter-life indicator. |
| Care and handling | The reviewed sources do not specify dishwasher care or a maximum water temperature for this pitcher. |
| Documented reduction and certification scope | The maker describes chlorine and taste-and-odor improvement and says the tourmaline stage reduces heavy metals including lead and mercury; no claim-specific performance sheet or certification was located. |

Full review: how the features affect your choice
What the features mean for you
Keep the documented pitcher family separate from the old listing
Clear2O's archived catalog labels its Mineral Rich Alkaline Pitcher as CAP350-BL, and its launch notice describes the same alkaline-pitcher family. The old source row gives a blue title and ASIN B00V5DNZY4, but neither manufacturer source maps that parent or verifies that exact finish. This review therefore describes the named current-family model rather than treating the historical title as proof of package identity. The reviewed materials also do not state total or filtered-water capacity in a reliable unit, so the finder cannot use the old listing's wording to satisfy a size requirement. Check the model label and filter code before treating a search result as this family.
Read the five filter stages as design information
The current CAF301 page describes a mesh screen, granular coconut carbon, a tourmaline mineral layer, pH-enhancing mineral media, and a non-woven membrane. It says the filter fits the CAP350BL pitcher. Clear2O associates the carbon stage with chlorine and taste-and-odor improvement and says the tourmaline stage reduces named heavy metals. Those statements explain the maker's intended design, but the reviewed pages do not provide numeric challenge results, an independent certification listing, or a performance data sheet. Do not translate a stage count or broad media description into a guaranteed result for a named water supply.
Plan replacement around the stated volume target
Clear2O states that the CAF301 processes up to 80 gallons. The launch material describes a True Life indicator that responds to the amount of water used rather than merely counting calendar time. The pages reviewed do not give a general month estimate, a daily processing limit, or an explanation of how the indicator is calibrated. Treat 80 gallons as the manufacturer's replacement target, not as a promise of identical service in every source-water condition. The filter code matters as well: the current page identifies CAF301 for CAP350BL, so verify that exact code before ordering a refill for an older pitcher.
Treat alkaline and mineral language as product description
Clear2O's 2015 launch notice says the system raises alkalinity and adds minerals such as calcium and magnesium. The current cartridge page likewise describes pH-enhancing mineral media. Those are descriptions of the product's intended water chemistry, not evidence for the broader health benefits asserted in the old promotional copy. The pages reviewed do not provide a health outcome, independent verification of the resulting pH for different source waters, or a certification claim for the pitcher. A shopper interested in this feature should evaluate the maker's documented product description without treating alkaline water as a medical or health intervention.
Who should keep this family on the shortlist
The CAP350-BL family may suit a shopper who specifically wants an alkaline and mineral-media pitcher, can verify the CAF301 cartridge, and accepts that the product information is more detailed about the replacement filter than about the pitcher body. It is less decisive for a buyer who needs documented cup capacity, a verified fit in a refrigerator shelf, dishwasher-safe care, or test-backed lead and mercury percentages. Use the tagged exact-model search as a way to find offers, then confirm the model and cartridge on the package. The article is based on manufacturer material and does not authenticate the historical parent or claim hands-on testing. A different model with a published performance sheet may be easier to compare when specific reduction percentages or certification are the main decision points. For this Clear2O family, the strongest supported comparisons are its named filter construction, replacement volume, and volume-based reminder, while the pitcher-size and care questions still need a matching manual.

Before you buy
Does CAP350-BL match the old blue Amazon listing?
The archived catalog identifies the CAP350-BL family, but the manufacturer sources reviewed do not map ASIN B00V5DNZY4 or verify that listing's blue variant.
Which replacement filter fits the CAP350BL pitcher?
Clear2O says its CAF301 five-stage Mineral Rich Alkaline replacement filter fits CAP350BL. Verify the code on an older pitcher before ordering.
Does Clear2O publish a certified lead-reduction result for this filter?
The current filter page describes a tourmaline stage and heavy-metal reduction, but the sources reviewed do not provide a model-specific performance data sheet or NSF/ANSI certification. No numeric certified claim is assigned here.
