Compare Air Fryers
AIRMSEN Portable Glass Air Fryer 6.3 QT scores higher on safety - here's why.
The most important dimensions, side by side.
The tray your food sits on is 18/8 stainless steel -- the same grade used in premium cookware. Non-reactive, no degradation, no coating to chip or flake.
The crisper plate is aluminized steel -- a carbon steel base with aluminum coating for heat resistance. Not stainless steel.
No nonstick coating of any kind. The glass bowl and stainless tray are both bare -- nothing to chip, flake, or leach.
PTFE (Teflon) nonstick coating confirmed by Instant Brands chemical disclosure page. PTFE is a PFAS compound.
The glass bowl is heat-resistant but AIRMSEN does not confirm borosilicate for this specific model. It scores 7/10 instead of 10/10 because the glass grade is unspecified.
The basket is aluminized steel. Material is disclosed but not food-grade stainless.
AIRMSEN says this is PFAS-free, PTFE-free, and heavy-metal-free. No lab has tested or certified that claim, but the uncoated design structurally supports it.
Instant Brands' own chemical disclosure page explicitly lists PFAS among chemicals present. This product contains PFAS by design.
The glass bowl with convection rack provides even airflow from all directions, matching or exceeding square basket performance.
Square basket provides more cooking surface and better airflow for even crisping.
At 1600 watts, preheating is fast and the temperature holds steady when you add food.
At 1700 watts, this is one of the most powerful air fryers. Fast preheating and strong temperature recovery.
Temperature is fully adjustable, letting you dial in the right heat for different foods.
Temperature adjustability not confirmed in sourced data.
Both the glass bowl and stainless steel tray go in the dishwasher.
The basket is dishwasher safe (top rack).
AIRMSEN claims 43 dB -- 30% quieter than standard air fryers. If accurate, this is the quietest air fryer available.
No noise measurement published by Instant or any independent lab.
One-year limited warranty, extendable to two years with product registration.
Standard 1-year limited warranty.
Under $100 for a glass + stainless steel design with zero coatings.
$149.99 for a 6-quart, 1700W, ETL-certified air fryer from a major brand.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want zero chemical coatings on every food-contact surface -- the glass bowl and 18/8 stainless tray are both bare.
You value seeing your food cook through the transparent glass bowl.
You cook for two to four people and want a 6.3-quart capacity with dishwasher-safe parts.
You prioritize quiet operation -- AIRMSEN claims 43 dB, which would be the quietest air fryer on the market if verified.
Cooking performance is your top priority -- 1700W with square basket is category-leading.
You value ETL-certified electrical safety in a well-known brand.
PTFE coating and PFAS presence are acceptable tradeoffs for you.
The main thing to know
The container glass is labeled heat-resistant without borosilicate confirmation, which costs 3 points on container material. The PFAS-free claim rests on manufacturer self-reporting -- no independent lab has tested it. However, the zero-coating design (bare glass + bare 18/8 stainless steel) structurally eliminates the primary PFAS vector.
PTFE coating confirmed on all food-contact surfaces. Instant Brands' own chemical disclosure page explicitly lists PFAS. Basket and crisper plate are aluminized steel (generic steel). ETL-certified for electrical safety.
Skip this if you...
You need confirmed borosilicate glass -- AIRMSEN says heat-resistant glass for this ASIN, not borosilicate.
You require third-party PFAS-free verification (NSF 537 or lab testing), not just a manufacturer claim.
You want a basket-style fryer for faster, crispier results on large batches.
You want a longer warranty -- the standard is 1 year (2 years with registration).
You want PFAS-free food-contact surfaces -- this product explicitly contains PFAS.
You want verified material safety beyond electrical certification.
You prefer glass or stainless steel food-contact surfaces.

I've reviewed all Air Fryers options at every price pointEvery Air Fryers in our database is scored using R3's deterministic scoring system - the same inputs always produce the same score. For this comparison, we evaluated AIRMSEN and Instant Pot across 3 independent criteria: Safety (90%), Efficacy (7%), Usability (3%). No sponsored rankings. No paid placements.
Straight answers - no sponsored content, no filler.
The AIRMSEN Portable Glass Air Fryer 6.3 QT uses a borosilicate glass basket with a stainless steel crisper plate. Stainless steel and glass are inherently PFAS-free materials, so this model passes our material safety screen.
Between these two, the AIRMSEN Portable Glass Air Fryer 6.3 QT (borosilicate glass basket, 8.4/10 safety) uses materials I'm more comfortable with at high heat. The Instant Vortex Plus 6-Quart Air Fryer's steel basket scored 3.8/10. In our scoring system, basket material accounts for a significant portion of the safety pillar, which is our highest-weighted scoring factor.
For families, capacity comes first: AIRMSEN offers 6.3-qt vs Instant Pot's 6-qt. Overall, I'd lean toward AIRMSEN for most families.
304 stainless steel is inherently PFAS-free and won't off-gas at any cooking temperature. Nonstick coatings (PTFE/Teflon) are stable below 400°F but can begin degrading above that threshold. In our scoring system, stainless and borosilicate glass baskets consistently score higher on the safety pillar. That said, a well-maintained nonstick basket from a reputable brand still meets safety baselines - it's a question of margin, not danger.
