Soma Further Push Pull Water Bottle
Lower concern for typical use; no known PFAS red flags, but brand silence leaves room for uncertainty.
Soma's Further Push Pull bottles are made from Tritan, a BPA-free plastic that does not require Teflon-type coating or Teflon-family coating coatings for function. The bottle has no intentional water-repellent, stain-resistant, or non-stick treatments typical of PFAS-risk products.

Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
The Soma Further Push Pull uses Tritan copolyester, a BPA-free plastic engineered to resist degradation from repeated washing and moderate heat exposure. Tritan has a stronger safety record than older polycarbonates and does not rely on bisphenol compounds. The stainless steel or plastic cap design minimizes direct contact between beverage and metals or degrading coating materials, reducing leaching pathways.
The brand's record and disclosure
Soma markets sustainability and health as core brand values but publishes minimal detail on material sourcing, manufacturing chemistry, or third-party testing. No major product recalls linked to leaching or contamination are on record for this model. The brand's silence on PFAS, while not unusual for small filtered-water companies, means no independent verification of manufacturing inputs is publicly available.
How it compares in its category
Filtered water bottles occupy a middle ground: they reduce reliance on single-use plastics and can lower certain contaminants, but introduce maintenance burden and filter-replacement waste. Soma's design is typical for this category. Alternatives like glass bottles eliminate plastic leaching risk entirely but trade portability; Soma's Tritan is a pragmatic compromise with no known leaching problems reported in public databases.
If you buy it
Replace filters every 40 gallons or 2 months, whichever comes first, to prevent bacterial biofilm and activated-carbon saturation. Avoid dishwasher heat cycles on the plastic body; hand-wash with warm water instead. Do not fill with boiling water or leave in direct sunlight for extended periods, as Tritan softens above 70C. Inspect the cap and filter housing monthly for cracks or discoloration signaling material degradation.
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 housing
If filters are not replaced on schedule or the bottle is left wet without drying, stagnant water in the filter chamber can harbor bacteria. This is a maintenance issue, not a material defect, but remains the primary health risk in filtered-bottle use.
Plastic leaching from Tritan body
Tritan copolyester has no established leaching issues under normal use conditions (room temperature, neutral pH beverages). No recalls or published studies document BPA, phthalates, or other monomers leaching from this material at typical storage temperatures.
Cap material degradation or contamination
If the cap is plastic, repeated thermal cycling and contact with acidic beverages (orange juice, vinegar-based drinks) can cause minor surface degradation. Stainless steel caps pose lower risk but may develop microscopic corrosion if scratched and exposed to chlorinated water.
Activated-carbon saturation reducing efficacy
Over time, the carbon filter loses absorption capacity and no longer removes chlorine, VOCs, or particulates effectively. This is not a toxicity hazard but signals reduced product function; filter replacement is essential.
Microplastics from filter material or housing wear
No published data documents microplastic shedding from Soma's filter or Tritan housing during normal use. Mechanical wear or heating could theoretically generate particles, but no incident reports exist for this product line.
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.
