SOMA Filter 6 Pack
Lower concern for PFAS; standard carbon filters rarely contain forever chemicals.
Filters with activated carbon and coconut shell media, materials lower in PFAS risk than coated or treated products. Brand makes no PFAS claims and no independent lab verification is public.

What SOMA Filter 6 Pack is made of, ingredients and materials
SOMA Filter cartridges use activated carbon derived from coconut shell combined with ion-exchange resin to reduce chlorine, sediment, and some contaminants from tap water. Coconut-shell carbon is a well-established filtration medium with no known leaching hazards under normal faucet-filter conditions. The plastic housing is typically polypropylene or similar food-contact polymers, which remain stable at room temperature and show no record of leaching issues when used as designed.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial growth in filter housing
If cartridges are not replaced on schedule or the filter sits unused for weeks, stagnant water can allow bacterial biofilm to form inside the plastic housing and saturated carbon. This is a maintenance issue, not a product defect.
Carbon dust or fines in filtered water
New or damaged activated carbon cartridges may release fine particles into water if not prewashed or if the internal mesh separators are compromised. Flushing the first liter of water after cartridge installation minimizes this risk.
Inadequate contaminant removal
Standard carbon filters do not remove bacteria, viruses, heavy metals, nitrates, fluoride, or PFAS. They reduce chlorine, sediment, and odor only. Users with specific contaminant concerns should test their water and consider certified systems.
Mold growth in filter connections
Moisture-rich connection points between the faucet and filter housing can develop mold if the filter sits unused or if the seal is poor. Regular rinsing and dry storage of the connection area prevent this.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Leaching from polypropylene housing
Food-contact polypropylene housings used in faucet filters are stable at room temperature and do not release BPA or phthalates under normal use. No recalls or test reports document leaching from Soma filter housings.
The full breakdown
The brand's record and disclosure
Soma does not publicly disclose detailed material safety data sheets or third-party certifications (such as NSF or WQA) on their website, which limits transparency compared to some competitors. The brand has no documented recalls or safety controversies on record. No established public statements exist regarding PFAS removal capability or manufacturing practices, leaving their stance neutral rather than explicitly proactive on forever chemicals.
How it compares in its category
Soma filters are consumer-grade pitcher and faucet filters without advanced certifications; they perform comparably to Brita and similar mass-market carbon filters. They are less rigorously tested than NSF-certified or pitcher filters with third-party validation. Standard activated carbon filters in this price tier do not remove PFAS, microplastics, or bacteria, only chlorine and some odors and sediment.
If you buy it
Replace cartridges every 2-3 months or per package instructions to prevent bacterial biofilm buildup inside exhausted filters and housing. Store unused cartridges in a cool, dry place away from direct sunlight. Do not use for contaminated or untreated water sources (well water, flood water) without testing. Rinse the filter housing periodically to avoid mold growth in the connection areas.
