Presto Cookware 6 Qt. S/S Pressure Cooker
Low-medium risk. Stainless steel cookware without nonstick coating poses minimal PFAS risk.
This stainless steel vessel has no nonstick or Teflon-family coating, substantially reducing PFAS exposure risk. The brand makes no PFAS claims, but food-grade stainless steel isn't known to leach PFAS under normal cooking conditions.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Stainless steel leaching (nickel, chromium)
Food-grade stainless steel (typically 300 series) releases trace metals only under extreme conditions (prolonged high acid, very high temperature, or mechanical damage). Normal pressure cooking poses minimal risk, but scratching the interior with metal utensils or storing acidic foods long-term can increase surface corrosion.
Pressure seal gasket degradation
Rubber gaskets in Presto cookers are known to degrade after 1-2 years of regular use, which can affect seal integrity but is a maintenance issue rather than a chemical hazard. Replacement gaskets are inexpensive and widely available.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Aluminum leaching (lid or internal components)
The 6-quart stainless steel vessel itself does not leach aluminum. If the lid or interior components contain aluminum (not confirmed in available specifications), minimal leaching would occur because the cooking environment is neutral to slightly acidic and not prolonged high-heat contact.
Teflon-type coating/nonstick fume release
This model uses no nonstick coating, eliminating Teflon-type coating decomposition risk. However, confirm lid gaskets and sealing components contain no Teflon-type coating; standard rubber gaskets pose no known chemical hazard when maintained properly.
Lead
This stainless steel model has no ceramic glaze, enamel coating, or decorative surface where lead or cadmium would typically concentrate. The exterior may have painted or printed labels, but these do not contact food.

What it's made of and why it matters
This Presto pressure cooker uses a stainless steel vessel, which does not require Teflon-family coating (Teflon-type coating) or other nonstick coatings. Stainless steel is chemically stable under normal cooking temperatures and does not off-gas harmful fumes when heated to typical cooking pressures (around 15 psi for this model). The absence of ceramic or enamel glazes eliminates concerns about lead or cadmium leaching from decorative coatings.
The brand's record and disclosure
Presto is a long-established U.S. pressure cooker manufacturer with no widely documented safety recalls specific to chemical leaching or coating hazards for their stainless steel models. The company does not publish detailed material safety disclosures or third-party certifications (such as NSF or GREENGUARD). No major controversies regarding heavy metals or toxic off-gassing have been established in the public record for this product line.
How it compares in its category
Stainless steel pressure cookers have lower concern for coating-related risks (Teflon-type coating fume release, ceramic glaze contamination) that affect nonstick or enameled alternatives. Budget-tier stainless models like this Presto are comparable to other mid-range brands (Instant Pot Duo Plus, T-fal) in material safety, though premium brands may offer thicker or higher-grade stainless. Price reflects reduced manufacturing oversight rather than inherently lower material safety.
If you buy it
Avoid overheating when empty or allowing prolonged exposure to extremely high flames, as all stainless steel can warp. Replace the rubber gasket every 12-24 months of regular use, as degraded seals can affect pressure retention and safety. Do not use corrosive cleaners or bleach, which can pit stainless steel over time. Hand-wash rather than dishwasher if possible to slow surface oxidation.
