SF100 Revitalizing Shower Filter
Skip. No PFAS disclosure; carbon filters carry unknown risk.
AquaBliss SF100 is a shower filter with activated carbon cartridges in stainless steel casing. Brand provides no PFAS information; carbon filters may contain PFAS or become contaminated, leaving user exposure unclear.

What SF100 Revitalizing Shower Filter is made of, ingredients and materials
The SF100 uses activated carbon as its primary filtration medium, a porous form of carbon that absorbs chlorine, some volatile organic compounds, and odor-causing molecules. The housing is stainless steel, which is chemically inert and does not leach metals into water under normal use. Activated carbon itself does not introduce known chemical hazards during water filtration, but its effectiveness and safety depend on proper maintenance and timely replacement to prevent bacterial biofilm growth inside the cartridge.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial growth in filter cartridge
Activated carbon is a nutrient-rich environment for bacteria if cartridges are not replaced on schedule or if water sits in the filter housing. Stagnant conditions (unused filter for weeks) increase biofilm risk; proper maintenance and timely replacement mitigate this.
Cartridge degradation or fragmentation
Over time or if subjected to thermal shock or high-pressure surges, activated carbon cartridges can crumble or shed fine particles into water. No on-record incidents for this model, but it is a known failure mode for carbon filters if not replaced or handled properly.
PFAS
Activated carbon can absorb certain PFAS depending on formulation, but AquaBliss provides no test data or certification confirming PFAS removal efficiency for the SF100. Without disclosure, it is unknown whether this filter reduces, redistributes, or does not address PFAS in tap water.
Source, ATSDR ↗Microplastics
Shower filters are not designed to capture microplastics; activated carbon does not reliably trap submicron plastic particles. This is typical of the category and not specific to AquaBliss, but it is a known limitation if microplastics are a concern in your source water.
Source, EPA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Leachables from housing seals or fasteners
Stainless steel housing does not leach under normal freshwater use. Seals (typically rubber or silicone) and any fasteners should be food-grade, but AquaBliss does not publicly disclose material specs for these components, so verification is not possible from available information.
How is this PFAS grade calculated?
The brand's record and disclosure
AquaBliss has not published third-party certifications (such as NSF/ANSI 42 or 53) or detailed disclosure about what contaminants the SF100 removes or how it handles PFAS and microplastics. The brand's silence on PFAS filtration capability is notable given that activated carbon CAN absorb some PFAS compounds, but performance varies by cartridge formulation and is not documented here. No major safety recalls or controversies appear on public record for this model, but lack of transparency limits independent verification of claims.
How it compares in its category
Shower filters typically rely on activated carbon or KDF media; this product is standard in that sense. Most competitors also lack rigorous third-party testing or PFAS-specific disclosure, so this is not unusual. The stainless steel housing is a modest advantage over plastic bodies, which can degrade over time; however, without NSF certification, the SF100 offers no independent guarantee of performance that distinguishes it from budget alternatives.
If you buy it
Replace the cartridge every 6 months or per manufacturer guidance, or sooner if water pressure drops or smell returns, to prevent bacterial colonization. Do not exceed the temperature rating stated on the filter housing; most shower filters are designed for water up to 45°C (113°F) and will fail at higher temperatures. Inspect the stainless steel housing and seals periodically for corrosion or loose connections. If you have specific concerns about PFAS in your water, request an independent lab test of your tap water and clarify with AquaBliss whether this cartridge has been tested for PFAS removal, as the existing evidence is not public.
