Clearly Filtered Water Bottle Removes 220+ Contaminants Double Wall Insulated Stainless Steel
Lower PFAS risk from housing; filter makeup opacity is the main concern.
Stainless steel double-wall housing carries lower PFAS concern. The internal filter media composition is unspecified and activated carbon filters can use PFAS-containing resins.

Material
Stainless steel double-wall insulated bottle with internal water filter (activated carbon/media unspecified)
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What Clearly Filtered Water Bottle Removes is made of, ingredients and materials
The bottle body is 18/8 or 18/10 food-grade stainless steel (double-wall construction), which does not leach metals under normal use conditions. The interior filter mechanism uses activated carbon media, but Aqua Vault's public materials do not specify the exact filter composition, binder materials, or whether granular or block carbon is used. This opacity prevents assessment of whether the filter housing or media could introduce contaminants during saturation or breakdown.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial or mold growth in double-wall insulation chamber
Double-wall bottles create a sealed air gap that is difficult to clean and rinse fully. If water enters the insulation layer or condensation accumulates, it can support microbial growth; stainless steel itself resists this, but the trapped space does not.
Filter media degradation and recontamination
Activated carbon filters lose capacity over time; Aqua Vault does not publish saturation timelines or post-use safety limits. Once saturated, carbon can release trapped contaminants or fail to block new ones, creating a false sense of safety.
Housing seal integrity and leachables from gasket/rubber components
The bottle's seal, lid gaskets, and filter cartridge housing likely contain elastomers or food-grade polymers; Aqua Vault does not disclose these materials or whether they are BPA-free or contain other plasticizers.
Unsubstantiated contaminant removal claims
The '220+ contaminants' claim lacks independent third-party testing or NSF listing. Activated carbon does remove some contaminants but not all (e.g., nitrates, fluoride, some microbes), and the specific filter media composition is undisclosed.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Aluminum leaching (if applicable to filter frame)
If the filter cartridge frame or internal components contain aluminum, corrosion or leaching is theoretically possible in acidic water. Aqua Vault has not published material specs to rule this out.
The full breakdown
The brand's record and disclosure
Aqua Vault maintains no published third-party certifications (NSF, WQA) for this product visible in public records. The brand does not disclose filter replacement intervals, post-saturation safety limits, or independent testing of the 220+ contaminant claim. No known recalls or safety incidents are on record, but the absence of transparent testing and certification standards is a red flag in the filtered water category.
How it compares in its category
Filtered water bottles range from non-certified (budget) to NSF-certified models; Aqua Vault sits in the middle-tier marketing space without third-party backing. Competitors like Soma, Brita portable, and professional brands (LifeStraw, Grayl) publish filter specifications and replacement schedules openly. The lack of independent validation for a 220+ contaminant claim is notably weaker than certified alternatives.
If you buy it
Replace the filter on the manufacturer's recommended schedule (typically 2-3 months); using a saturated filter may allow trapped contaminants to re-leach or bacterial growth. Do not use boiling water or leave the bottle in direct sunlight for extended periods, as this can degrade the seal and activate carbon performance. Clean the bottle interior weekly and allow to air dry fully to prevent mold in the insulated chamber. Request the filter spec sheet directly from Aqua Vault before purchase if you need contaminant-specific confidence.
