Ember Choral Arts Stainless Steel Water Bottle, Ember Choral Arts
Stainless steel water bottle, lower PFAS concern, no coating risk.
This Ember water bottle is bare stainless steel without coatings. Bare stainless steel presents minimal PFAS risk since Teflon-family coating coatings don't apply to this product type.

What Ember Choral Arts Stainless Steel Water is made of, ingredients and materials
This bottle is constructed from stainless steel with no internal polymer coating, enamel, or paint layer. Uncoated stainless steel is inert at normal use temperatures and does not release heavy metals (lead, cadmium) or Teflon-type coating fumes because no such layers exist. The material's primary risk, leaching of nickel or chromium, is negligible in water storage at room temperature, as stainless steel passivation prevents surface degradation under neutral pH conditions.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Trace nickel or chromium leaching
Stainless steel contains small amounts of nickel and chromium. At neutral pH and room temperature, leaching is minimal; acidic beverages stored for extended periods may marginally increase trace metal transfer. Levels remain well below EPA drinking water standards for chromium and below typical dietary nickel intake for most users.
Bacterial growth in cap gasket
The rubber or silicone gasket in the lid can harbor bacteria if not dried thoroughly after washing. This is a maintenance issue, not a material defect, and is common to all reusable water bottles. Regular cleaning and air-drying mitigate this risk.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Coating degradation (if present)
Uncoated stainless steel has no enamel, paint, or polymer lining to degrade or chip. This eliminates the primary coating-related hazard class for drinkware.
Heavy metals
No ceramic glaze, enamel coating, or paint layer is present on this product. Lead and cadmium concerns associated with ceramic or painted drinkware do not apply to bare stainless steel.
Source, FDA ↗Teflon-type coating or nonstick fume risk
The product contains no Teflon-type coating (Teflon) or nonstick coating. Teflon-type coating fume hazards associated with scratched nonstick-lined bottles are not relevant to uncoated stainless steel.
The full breakdown
The brand's record and disclosure
Ember has not made public statements on PFAS policy, material sourcing, or third-party safety testing for this product line. No major recalls or safety controversies are on record for this brand or bottle model. The absence of disclosure does not indicate a hazard; it reflects typical practice for smaller cookware/drinkware brands without formal safety certifications.
How it compares in its category
Uncoated stainless steel water bottles are among the lowest-risk reusable bottle options. They avoid BPA, BPS, and phthalate concerns common in plastic bottles and bypass coating-related risks (PFOA, lead) in ceramic or nonstick-lined alternatives. The main trade-off is weight and cost versus lighter plastic or coated options.
If you buy it
Wash with mild soap and water; dishwasher-safe if manufacturer specifies. Avoid prolonged exposure to acidic liquids (vinegar, citrus juice) which may slightly increase trace nickel leaching over years, though at levels well below health thresholds. Inspect the cap seal and gasket annually; replace if cracked or degraded to prevent bacterial growth in the lid. Stainless steel does not degrade with normal use and does not require replacement unless dented or the seal fails.
