HansGrohe Ceramic Cartridge 96623001
Lower-concern choice; ceramic is inherently PFAS-free, but Hansgrohe does not publicly disclose PFAS policy.
Hansgrohe's ceramic cartridge is a water-filtration component made from ceramic, a material intrinsically free of PFAS compounds. However, Hansgrohe does not provide public PFAS disclosure or testing data for this product.

The full breakdown
What it's made of and why it matters
The Hansgrohe 96623001 is a ceramic filter cartridge designed to remove sediment, chlorine, and taste/odor compounds from shower water. Ceramic itself is a non-leaching, inert material that does not degrade into harmful compounds when exposed to water or temperature fluctuations typical of shower use (up to 60°C/140°F). Unlike activated carbon or synthetic resin cartridges, ceramic does not shed microparticles into water when functioning normally, and it does not absorb and re-release contaminants over time.
The brand's record and disclosure
Hansgrohe is a German premium plumbing manufacturer with no publicly documented recalls or safety controversies related to this cartridge model. The company does not publish explicit PFAS avoidance policies or third-party safety certifications specific to their filter cartridges. No independent testing of Hansgrohe ceramic cartridges for heavy metals or contaminant leaching appears in consumer safety databases, though the brand maintains ISO 9001 and general water safety compliance.
How it compares in its category
Ceramic cartridges are among the safest filtration media available because they are chemically stable and do not rely on polymers, adhesives, or ion-exchange resins that can leach into water. This model is comparable to other premium ceramic shower filters in terms of material safety. Many budget filter cartridges use activated carbon or synthetic binders that carry microleaching risks; ceramic avoids these entirely.
If you buy it
Replace the cartridge every 6-12 months depending on water hardness and sediment load to prevent bacterial biofilm accumulation inside the ceramic pores. Do not exceed the manufacturer's rated flow rate or pressure, as this can crack the ceramic and bypass filtration. Rinse the cartridge under tap water monthly to extend performance. Store replacement cartridges in a dry location away from direct sunlight and extreme temperature swings.
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 colonization in filter media
Ceramic cartridges with high porosity can harbor biofilm if not rinsed regularly or if water stagnates in the housing. This is a maintenance issue, not a material defect, but risk exists if cartridge is left in place beyond recommended replacement interval.
Housing material leachables
The 96623001 cartridge itself is ceramic, but leachables depend on the filter housing (typically plastic or metal). No documented issues with Hansgrohe housing materials, but housing material composition is not publicly detailed in product specs.
Ceramic microfracture and particle shedding
Thermal shock from sudden water temperature changes or physical impact can cause hairline cracks in the ceramic, potentially releasing fine ceramic particles into water. Risk is low under normal shower use but increases if housing is dropped or exposed to temperature swings above 20°C.
Heavy metals in ceramic glaze (if present)
High-quality ceramic cartridges like Hansgrohe's should not contain lead or cadmium in glazes, but the manufacturer does not provide material safety data or third-party test results confirming this. Absence of evidence is not confirmation of safety.
Water pressure bypass if cartridge clogs
Excessive sediment or mineral buildup can cause the cartridge to clog, and high water pressure may force bypass around the filter rather than through it, leaving contaminants unfiltered. This is a usage/maintenance risk, not a material hazard.
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.
