Air Fryer vs Convection Microwave: The Real Difference
What Is a Convection Microwave?
The air fryer vs convection microwave comparison confuses most Indian buyers because both use fan-circulated hot air to cook food.
A convection microwave is a 3-in-1 appliance. It combines a regular microwave (for reheating), a conventional oven (for baking), and a convection fan (for air circulation). You can switch between modes depending on what you are cooking.
In convection mode, it works similarly to an air fryer — a fan circulates hot air inside the cavity to cook and brown food. This is why people often wonder if they even need an air fryer when they already have a convection microwave.
The key difference is the chamber size. A convection microwave has a 20-32 litre cavity. An air fryer has a 2-7 litre cavity. The smaller the chamber, the more intensely the hot air hits the food, which means crispier results.
Think of it this way: A convection microwave is a jack of all trades. An air fryer is a specialist at one thing — making food crispy with minimum oil. The specialist usually outperforms the generalist at its specific task.
Air Fryer vs Convection Microwave: Full Comparison
| Feature. | Air Fryer. | Convection Microwave. |
|---|---|---|
| Cooking modes. | Air fry only (convection). | Microwave + Oven + Convection + Grill + Combo. |
| Crispiness. | Excellent — intense, focused airflow. | Good — but less intense due to larger cavity. |
| Reheating. | 5-10 minutes (slow). | 1-3 minutes (microwave mode). |
| Defrosting. | Not possible. | Yes — dedicated defrost mode. |
| Baking. | Limited (small items). | Good — oven + convection mode. |
| Capacity. | 2-7 litres. | 20-32 litres. |
| Price range (India). | Rs 2,000-8,000. | Rs 8,000-25,000. |
| Counter space. | Compact. | Large. |
| Ease of use. | Very simple — set temp and time. | Complex — multiple modes, settings, and combos. |
| Cleaning. | Easy — removable basket. | Harder — large cavity, turntable, walls. |
| Preheat time. | 2-3 minutes. | 5-10 minutes (convection mode). |
| Best for. | Crispy snacks, oil-free frying. | All-in-one: reheat, bake, grill, and convection cook. |
Which Gives Crispier Results?
The air fryer wins on crispiness — every time. Here is why.
An air fryer has a small, compact cooking chamber (2-7 litres). The fan is positioned close to the food and pushes air at very high speed. This creates intense, focused heat that hits every surface of the food rapidly. The result is a deep golden, crispy exterior in 10-15 minutes.
A convection microwave has a much larger cavity (20-32 litres). The fan is further from the food, and the hot air has more space to disperse before reaching the food surface. The crispiness is decent — better than a regular microwave — but noticeably less than a dedicated air fryer.
I tested samosas in both. Here are the honest results:
| Item. | Air Fryer Result. | Convection Microwave Result. |
|---|---|---|
| Frozen samosa. | Crispy, golden, flaky pastry — 10 min at 180 degrees C. | Browned but less crispy — 15 min at 200 degrees C. |
| French fries. | Crispy outside, fluffy inside — 15 min. | Lightly browned, slightly soft — 20 min. |
| Paneer tikka. | Charred edges, juicy — 10 min. | Evenly cooked, mild browning — 15 min. |
| Chicken wings. | Crispy skin, juicy meat — 18 min. | Cooked through, skin not crispy — 22 min. |
Verdict: If crispy fried snacks are your main use case, the air fryer is worth owning even if you already have a convection microwave.

Which Is More Versatile?
The convection microwave is far more versatile. It is one appliance that replaces a microwave, an oven, and (partially) an air fryer. For Indian kitchens with limited counter space and budget, this all-in-one approach is appealing.
What a convection microwave can do that an air fryer cannot:
- Reheat dal, rice, sabzi in 2 minutes.
- Defrost frozen meat and vegetables.
- Heat milk and water for chai.
- Bake cakes, bread, and cookies (oven mode).
- Grill with top-element heating.
- Cook in combination modes (microwave + convection for faster results).
What an air fryer can do better than a convection microwave:
- Make crispier fried snacks (samosa, pakora, fries).
- Produce better char and browning on tandoori items.
- Cook faster for small batches (smaller preheat time).
- Use less electricity per frying session.
Price and Value Comparison
This is where the air fryer has a massive advantage. A good air fryer costs Rs 2,000-8,000. A convection microwave costs Rs 8,000-25,000. That is a 3-5x price difference.
| Option. | Cost. | What You Get. |
|---|---|---|
| Air fryer alone. | Rs 3,000-5,000. | Crispy frying, roasting, small baking. |
| Regular microwave + air fryer. | Rs 8,000-12,000 total. | Best reheating + best frying — two specialists. |
| Convection microwave alone. | Rs 10,000-20,000. | Reheating + decent baking + average frying — one generalist. |
Best value option: A regular microwave (Rs 5,000) plus an air fryer (Rs 3,000) gives you the best of both worlds for Rs 8,000 — cheaper than most convection microwaves. And each appliance excels at its specific job instead of being average at everything.
Who Should Buy Which?
Buy a convection microwave if:
- You want one appliance that does everything (reheat, bake, grill, convection cook).
- Counter space is very limited — you can only fit one appliance.
- You do not fry snacks very often (2-3 times a week or less).
- You bake occasionally and want oven functionality.
Buy an air fryer if:
- You already have a regular microwave for reheating.
- Maximum crispiness is important to you.
- You fry snacks 3 or more times a week.
- You want a cheaper, simpler appliance.
- You have a small family (2-4 people).
Buy both if:
- You already own a convection microwave but find its convection mode disappointing for snacks — adding a Rs 3,000 air fryer solves the crispiness problem.

Frequently Asked Questions
Can a convection microwave replace an air fryer?
Partially. A convection microwave can brown and crisp food using its convection mode, but the results are not as crispy as a dedicated air fryer. If you fry snacks occasionally, the convection microwave is good enough. If you fry daily and want maximum crispiness, you will notice the difference.
Is a convection microwave better than an air fryer for Indian cooking?
It depends on what you cook most. For reheating dal and rice, defrosting, and baking — the convection microwave is better. For making crispy samosas, pakoras, tikka, and fries — the air fryer is better. Neither is universally better. They serve different primary purposes.
Do I need an air fryer if I have a convection microwave?
If you fry snacks 3 or more times a week and want restaurant-level crispiness, yes. A budget air fryer costs only Rs 2,500-3,000 and significantly improves the crispiness of fried foods compared to your convection microwave's convection mode. If you rarely fry, you do not need one.
Why is an air fryer crispier than a convection microwave?
The air fryer has a much smaller cooking chamber (2-7 litres vs 20-32 litres). This means the hot air is more concentrated and hits the food surface with more intensity. The fan is also closer to the food and spins faster. More intense, focused airflow equals crispier results.
Which is more energy-efficient — air fryer or convection microwave?
For frying and convection cooking, the air fryer uses less electricity per session because it preheats faster and cooks faster in the smaller chamber. For reheating, the convection microwave's microwave mode is more energy-efficient because it heats food in 1-3 minutes.
