Great Value Water Filter Pitcher HS528N
Lower concern water filter; no PFAS risk inherent to activated carbon cartridges, but brand makes no transparency claim.
The HS528N appears to use standard activated carbon filtration, which does not inherently contain PFAS. Water filter pitchers are generally lower-risk products since the filtration media (carbon, ion-exchange resin) are not treated with water-repellent coatings.

The full breakdown
What it's made of and why it matters
The HS528N pitcher body is polypropylene (PP) plastic, which is food-contact safe and resistant to leaching under normal cold-water use. The replaceable cartridge contains activated carbon and ion-exchange resin, both of which are non-toxic, inert materials that trap contaminants rather than releasing them. Activated carbon has no known off-gassing or degradation hazards at room temperature. The plastic pitcher itself does not involve coatings, glazes, or adhesives known to release heavy metals or endocrine disruptors.
The brand's record and disclosure
Filtersmart (the manufacturer of the HS528N, sold under the Great Value label by Walmart) maintains minimal public transparency on third-party testing or material certification. No product recalls or safety violations are on record for this specific model. The brand does not publish voluntary PFAS reduction statements, but this is not unusual for budget pitcher filters and does not indicate a safety failure, since activated carbon cartridges are not a PFAS source. NSF or WQA certification data for this model is not publicly documented.
How it compares in its category
Budget pitcher filters (under $30) typically use polypropylene housings and carbon cartridges, making the HS528N materially representative of its price tier. Unlike premium pitcher brands (Brita, ZeroWater), Filtersmart does not advertise independent lab testing or publication of contaminant reduction percentages. The design is functionally similar to generic competitors; the main trade-off is lower transparency rather than higher chemical hazard. Performance and safety sit at category average.
If you buy it
Replace the cartridge every 2 months or 40 gallons to prevent bacterial biofilm buildup inside spent filters, a known hygiene risk in all pitcher filters. Store the pitcher in a cool, dry place away from direct sunlight; polypropylene can soften or degrade if exposed to heat above 60-70°C, though normal kitchen use poses no risk. Never fill with hot water, and rinse the pitcher weekly to prevent mold on the housing interior. Keep replacement cartridges sealed until use.
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.”
Bacterial growth in filter cartridge
All pitcher filters face biofilm accumulation if cartridges are not replaced on schedule. The HS528N has no antimicrobial or self-cleaning mechanism documented; risk depends entirely on user maintenance discipline.
Polypropylene pitcher housing leaching (cold water)
Polypropylene is chemically stable under cold-water storage and does not release BPA, phthalates, or heavy metals under normal use. No recalls or test failures have been reported for this product or material class in pitcher filters.
Activated carbon and ion-exchange resin safety
Both materials are food-contact approved and inert. They are designed to absorb contaminants, not leach them. No hazard associated with these cartridge materials is documented in water filter literature or regulatory databases.
Filter housing durability and seal integrity
Budget pitcher filters may develop cracks or seal degradation over 1-2 years of use, potentially allowing unfiltered water bypass. Regular visual inspection of the pitcher and cartridge seating is recommended to maintain filtration effectiveness.
Manufacturing process transparency (trace contaminants)
The brand does not disclose manufacturing location, quality control, or pre-filtration protocols for cartridge materials. No contamination incidents are on record, but independent verification of cartridge purity is not publicly available.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
