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.
Aluminum without food-grade qualifier — unconfirmed whether anodized, treated, or raw. Raw aluminum can leach into acidic foods. Score 4 reflects disclosed material without food-grade certification.
No nonstick coating of any kind. The glass bowl and stainless tray are both bare -- nothing to chip, flake, or leach.
nano-ceramic: engineered nano-scale particles (1–100nm) have documented enhanced penetration risk under abrasion vs standard ceramic — SKL explicitly rejected Ninja Crispi for 'nano-ceramic with limited transparency'. proprietary-not-disclosed: 'nonstick' without coating name — cannot assess PFAS/PTFE content. Both score 1 per opacity principle.
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.
All confirmed food-grade material families: borosilicate glass (chemically inert, heat-resistant), 304/316/18-8/18-10 stainless (FDA 21 CFR compliant, non-reactive, corrosion-resistant). Explicit grade confirmation required to score 10 — 'stainless' alone maps to score 8. Both families recommended by primary sources as safest available.
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.
Brand self-reports PFAS-free or PTFE-free without naming a certifying body or publishing a test report. SKL: 'PFAS-free does not guarantee a product is completely non-toxic.' No evidentiary weight, but positive claim is better than silence.
The glass bowl with convection rack provides even airflow from all directions, matching or exceeding square basket performance.
Serious Eats 34-model test: square baskets 'consistently outperform round for crisping quality' — more surface area, better airflow. Glass-bowl-convection-rack provides 360° airflow. Both represent optimal cooking geometry.
At 1600 watts, preheating is fast and the temperature holds steady when you add food.
Fastest preheat, strongest temperature maintenance. Tom's Guide top pick (Ninja Pro) at 1750W rated 'supremely powerful'.
Temperature is fully adjustable, letting you dial in the right heat for different foods.

AIRMSEN claims 43 dB -- 30% quieter than standard air fryers. If accurate, this is the quietest air fryer available.
Loud — Ninja Pro at 72 dB (loudest in Tom's Guide testing).
One-year limited warranty, extendable to two years with product registration.
1 year: baseline industry standard.
Under $100 for a glass + stainless steel design with zero coatings.
$161–300: premium range.
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.
You want the most powerful glass air fryer available -- 1800W is best-in-class.
You need 450F max temperature for high-heat cooking like searing.
You accept nano-ceramic crisper plates and the glass container design tradeoff.
The 6-in-1 functionality with two container sizes adds versatility for your kitchen.
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.
Same nano-ceramic crisper plate concern as the Crispi 4-in-1, with bare aluminum base and limited coating transparency per Sustainably Kind Living. At 299 dollars, this is 120 dollars more than the Crispi 4-in-1 but scores identically on safety. The extra cost buys 300W more power and louder operation at 72 dB -- the loudest air fryer tested by Tom's Guide.
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 are noise-sensitive -- 72 dB is the loudest air fryer tested, louder than a normal conversation.
The 300-dollar price point seems high when the cheaper Crispi 4-in-1 has the same safety profile at 180 dollars.
You want zero coating risk -- nano-ceramic has limited transparency per Sustainably Kind Living.
You require independently verified PFAS-free testing or UL/ETL certification.
Neither of these quite what you're looking for?
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 Ninja 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 Ninja Crispi Pro 6-in-1 Glass Air Fryer's borosilicate glass basket scored 4.5/10. 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: check the capacity specs for your family size. 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.
