Alkaline Water Plus · Pitcher Water Filters & Cartridges
DIJA Alkaline Water Filter Pitcher
Lower PFAS risk than coated cookware, but no public disclosure, pitcher material and filter contents unclear.
Alkaline Water Plus does not publicly disclose PFAS presence or absence in the DIJA pitcher or its filters. Standard carbon and ion-exchange filters typically contain lower PFAS risk than Teflon-family coating coatings, but activated carbon itself may trap legacy PFAS from source water.

The full breakdown
What it's made of and why it matters
The DIJA pitcher is a plastic housing (material type not publicly specified by the brand) paired with a replaceable cartridge containing activated carbon and mineral media claimed to ionize water. Activated carbon is food-safe when properly manufactured, but the pitcher's plastic composition and whether it is BPA-free or contains other leachable polymers remains undisclosed. The mineral cartridge contents (calcium, magnesium salts, or other alkalizing agents) are not itemized, making it impossible to assess whether they are regulated food-contact materials or if they can shed particulates into drinking water over time.
The brand's record and disclosure
Alkaline Water Plus maintains minimal public safety documentation. No third-party certifications (NSF, WQA, FDA approval for claims) are readily available for this specific model. The brand does not openly address cartridge material safety, filter replacement schedules, or whether the pitcher meets FDA food-contact plastic standards. No major recalls have been identified for this product, but the lack of transparency on material sourcing and testing is a red flag for a consumable item.
How it compares in its category
Alkaline pitchers like this occupy a middle tier of water-filter products: less regulated than under-sink reverse osmosis systems, less transparent than major brands (Brita, PUR) that publish cartridge material specs and NSF certifications. Most competitor pitchers explicitly state BPA-free plastic and activated-carbon sources; DIJA's silence suggests either use of older plastic formulations or reluctance to disclose. Ionization claims in alkaline pitchers lack strong scientific backing and are not endorsed by major health authorities.
If you buy it
Replace cartridges every 40-60 gallons (or per label instructions) to prevent bacterial growth and carbon saturation, which can reduce filtration and allow contaminants through. Do not fill with water hotter than room temperature, as heat can accelerate plastic leaching. Store the pitcher in a cool, dark place and clean the housing weekly with unscented dish soap. If the plastic smells strongly of chemicals or tastes transfer to water, discontinue use and contact the manufacturer for a replacement unit.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Plastic leaching (BPA, phthalates, or undefined polymer additives)
The pitcher's plastic type is not publicly disclosed by the brand. If the housing uses polycarbonate or older polypropylene formulations, BPA or phthalate leaching is possible, especially if water sits in the pitcher for extended periods. No test data from DIJA is available to confirm BPA-free status.
Cartridge particulate shedding and bacterial growth
Activated carbon can shed fine black particles if the cartridge degrades or is installed incorrectly; mineral media cartridges may fragment or leach mineral powder if water pressure is high or the cartridge is old. Unmaintained cartridges (replaced infrequently) provide ideal conditions for bacterial biofilm growth, especially if water remains in the pitcher for days.
Undisclosed cartridge material composition
The brand does not publish detailed safety data sheets or certifications for the cartridge's mineral alkalizing agents or binder materials. These could include synthetic resins, epoxy coatings, or proprietary minerals not rated for food contact, creating a theoretical risk if leaching occurs.
Microbiological contamination from standing water
Pitcher filters reduce but do not eliminate all bacteria; standing water in the pitcher for more than 24-48 hours can allow residual microorganisms to proliferate. The brand provides no guidance on water storage limits, increasing the risk of stale, contaminated water being consumed.
Unsubstantiated health claims regarding ionization
Alkaline water ionization claims are not supported by FDA or major health bodies. Consumers relying on this pitcher as a health intervention rather than a basic filter may delay treatment of serious conditions. This is a marketing hazard, not a chemical one, but relevant to informed purchasing.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 55% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
