Most air fryers on the market use a non-stick-coated basket. LUMA, made by the Indian kitchen appliance brand EDT, replaces that basket entirely with a glass bowl, and builds its entire pitch around removing coatings from the cooking surface rather than improving them. Here is what that actually means in practice, what the specifications say, and whether it is worth the premium over a conventional coated air fryer.
Quick Answers
| Question | Short Answers |

What Makes LUMA Different From a Standard Air Fryer
Almost every air fryer on the market, regardless of brand or price, uses the same basic design: a metal basket coated in a non-stick layer, usually a PTFE-based coating (commonly known by the brand name Teflon), sitting inside a plastic or metal housing.
LUMA replaces that basket with a 6mm double-tempered borosilicate glass bowl, EDT's PureGlass construction. There is no non-stick coating anywhere in the cooking chamber. The crisper tray inside the bowl is uncoated SS304 stainless steel rather than a coated metal tray. EDT markets this as "zero coating," and the underlying claim, no PTFE, PFAS or PFOA on the cooking surface, is a real and verifiable design choice, not just a marketing phrase. Whether that matters to you depends on how you weigh the health and safety questions around non-stick coatings, which we cover in full in are air fryer coatings safe: PFAS, PTFE and PFOA explained.

Real-World Cooking Range
Because LUMA functions as a small oven rather than a basket-only fryer, its six modes cover more ground than a typical single-purpose air fryer:
- Air fry: crisping fries, pakoras, samosas, fried chicken, or fish
- Bake: cakes, cookies, brownies, small pizzas
- Roast: roasted nuts, makhana, stuffed mushrooms, paneer, tandoori-style chicken
- Grill: kebabs, skewers, grilled sandwiches
- Toast and reheat: everyday reheating, with a stated default of 165°C for 7 minutes
This range is closer to a compact countertop oven than a basket air fryer, which is worth knowing if you were expecting a simple fries-and-nuggets appliance. For people who already own a coated air fryer and are deciding whether a switch is worth it, glass vs ceramic vs non-stick air fryers: which is actually safest lays out the practical differences beyond the coating question.
Claimed Technologies, and How to Read Them
EDT names several proprietary technologies on the LUMA's spec sheet. It is worth separating what is independently verifiable from what is a brand claim you should treat as marketing until tested yourself:
- NutriRetain (heat calibration): EDT states this preserves more nutrients during cooking, citing a specific figure (41.4% more vitamin retention in vegetables) in its own marketing. This is a brand-reported claim, not an independently verified, third-party test result, so treat the exact percentage with appropriate scepticism even if the underlying principle, that gentler, more even heat distribution can reduce nutrient loss compared to harsher direct heat, is generally plausible.
- NeuroKeep (auto pause/resume): A genuinely useful, verifiable convenience feature: opening the bowl mid-cook pauses the appliance, and closing it resumes from where you left off, rather than restarting the cycle.
- 360° isothermal heat: A description of even heat distribution around the bowl rather than heat concentrated from one direction. This is a real design goal of oven-style air fryers generally, not unique to LUMA, though the specific execution varies by brand.
Noise, Cleaning and Everyday Use
EDT states an operating noise level of 56dB, which the brand positions as quieter than typical coated air fryers (which often run louder due to fan and motor design). A glass bowl also has a straightforward cleaning advantage over a coated metal basket: food residue does not cling to microscopic scratches or worn coating patches the way it can on an ageing non-stick surface, and the brand states the bowl is dishwasher safe. We go through the full cleaning process, including what to do about the crisper tray and base unit, in how to clean an air fryer, and why glass bowls make it easier.
Price and What You Are Actually Paying For
At ₹8,999 (against a stated ₹12,499 list price at the time of writing), LUMA sits above many entry-level coated air fryers of similar capacity, which commonly sell in the ₹3,000 to ₹6,000 range in India. The premium buys three things specifically: the glass and uncoated-steel construction, the multi-mode oven-style cooking range rather than a single-function fryer, and EDT's stated after-sales service network (doorstep service across a claimed 19,000+ pincodes, 1-year warranty, 7-day replacement).
If your only requirement is a basic fries-and-snacks fryer and coating material is not a concern for you, a cheaper coated basket fryer will do that specific job for less money. If avoiding non-stick coatings is a genuine priority, or you want an appliance that covers baking, roasting and grilling as well as frying, LUMA's price makes more sense in context.
Who Should Buy LUMA
Consider it if:
- You specifically want to avoid PTFE, PFAS or PFOA coatings on cookware, whether for health, environmental or personal preference reasons
- You want one appliance that covers air frying, baking, roasting, grilling and reheating rather than several single-purpose gadgets
- You are comfortable with, or actively prefer, the visibility a glass bowl offers during cooking
Think twice if:
- Your budget is under ₹6,000, and coating material is not a priority for you
- You specifically want a compact, single-purpose basket fryer rather than an oven-style multi-mode appliance
- You are sensitive to occasional stock availability issues, since glass-bowl air fryers, being a newer manufacturing category, can see longer restock cycles than mass-produced coated fryers
