Our take
Membrane Solutions DP01 is a small 5-cup pitcher on the manufacturer's US-facing product page, which lists 1.2 L capacity, compact dimensions, and a 40-gallon filter claim. The product may suit a one-person kitchen, office, or small refrigerator where a full-size pitcher is awkward. The evidence is less clear on performance: the page's prose names chlorine, lead, fluoride, copper, mercury, zinc, and cadmium, while the structured parameter table identifies only chlorine taste and odor. Another parameter field calls the item a shower filter. I treat the model and basic size as supported, but leave the conflicting claims and old blue Amazon variant unresolved.
Consider the DP01 if a compact 5-cup pitcher is useful and you are comfortable relying only on its clearly stated chlorine taste-and-odor claim until the maker clarifies the other reduction claims. Verify the DP01 model and finish before ordering from the historical listing..
Do not use the DP01 as a confirmed lead, fluoride, or heavy-metal solution on this page alone; the maker's performance fields conflict and no model-specific test sheet or certification is linked. It is also not a good fit if you need a larger serving reserve, a confirmed blue finish, an electronic reminder, or dishwasher-care guidance.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manufacturer identifies DP01 as a 5-cup, 1.2 L pitcher and provides stated dimensions and weight.
- The page gives a 40-gallon filter life and an average four-month replacement interval.
- Chlorine taste and odor reduction is present both in the feature description and the structured contaminant field.
What to weigh up
- The page's prose lists several reductions, but its parameter table lists only chlorine taste and odor; the other claims remain unresolved.
- A parameter field labels the item a shower water filter even though the page title and model description call it a pitcher.
- No NSF/ANSI certification, filter-stage count, exact cartridge code, dishwasher instruction, or historical Amazon parent is established on the page.

Full review: how the features affect your choice
What the features mean for you
Check whether a five-cup pitcher is enough
The manufacturer identifies DP01 as a 5-cup water-filter pitcher with a stated 1.2 L capacity. It lists a height of 10.4 inches, width of 2.8 inches, depth of 7.1 inches, and weight of 1 pound. That compact footprint is the product's most concrete differentiator for a desk, small household, travel lodging, or a refrigerator with limited room. The historical row describes a blue DP01 mini pitcher, but the manufacturer's page does not prove that finish or the old Amazon parent. Measure the space you have and check the exact model and color on the item before ordering.
Separate the clear chlorine statement from disputed claims
The DP01 page's structured parameter row lists chlorine taste and odor as its contaminant removal field. Elsewhere, the prose claims the pitcher also reduces lead, fluoride, copper, mercury, zinc, and cadmium. Because the page itself does not reconcile the broader prose with the narrower structured field, this review treats chlorine taste and odor as the only clear claim and leaves lead and mercury unknown. The maker page does not identify NSF/ANSI certification or provide a model-specific data sheet in the source reviewed. If you need a particular health-related reduction, ask the manufacturer for the DP01 test report and certification before relying on the broader copy.
A 40-gallon claim and a four-month average
The manufacturer says one DP01 filter can handle 40 gallons of water and gives an average life of four months. Those are two different kinds of guidance: the gallon figure is a volume claim, while the month figure is an average schedule. Follow the instructions supplied with the exact product and account for how much water your household filters. The page does not describe a reminder, maximum daily flow, or the exact replacement-filter model number, so owners should identify the compatible cartridge before buying replacements rather than relying on the pitcher name alone.
Treat the page's product-type field as an open inconsistency
The page heading and feature copy call DP01 a 5-cup water-filter pitcher, and the historical candidate row also describes a mini pitcher. One structured parameter nevertheless labels its product type as a shower water filter. The more specific model name, capacity, household suitability field, and pitcher-focused page content support keeping this as a pitcher-family lead, but the inconsistent field belongs in the evidence record. It is not appropriate to erase the discrepancy or infer that the row is an unrelated shower product. The precise blue Amazon listing remains unconfirmed, so use the product model and size as the search terms and inspect the listing carefully.
Choose it for size, not for undocumented assurances
The DP01 is easiest to justify when the small format is the main requirement and chlorine taste and odor is the only reduction claim you need from the page. Its four-month average gives a simple routine, and the stated 40-gallon limit gives a volume reference. The same source does not answer whether the pitcher is dishwasher safe, which NSF/ANSI standards it meets, or which cartridge code to order. Those omissions matter if you are comparing certification-backed contaminant claims or want low-maintenance cleaning. Keep those attributes unknown in the finder, and do not let its unsupported claims satisfy a hard lead, PFAS, or microplastics requirement.

Before you buy
How much water does the DP01 pitcher hold?
The manufacturer page identifies it as a 5-cup pitcher with a 1.2 L capacity. It lists dimensions of 10.4 by 2.8 by 7.1 inches and a weight of 1 pound; the historic blue finish is not confirmed.
Does the DP01 reduce lead and other metals?
The page's prose claims reductions for several substances, including lead and mercury, but its structured contaminant field lists only chlorine taste and odor. Get a DP01-specific test report from the manufacturer before relying on the broader claims.
How long does a DP01 filter last?
The manufacturer states 40 gallons and an average of four months. The actual calendar period depends on how much water you filter; the page does not provide a specific replacement-cartridge code.
