You want one countertop appliance that replaces three cluttering machines — a microwave for quick reheats, an air fryer for crispy fries, and a convection oven for roasting. The catch is that most multi-function ovens compromise on at least one job. This guide walks you through nine models that genuinely combine all three, pinpointing which ones deliver on each function without making you wish you had kept your old appliances.
I’m Rikta — the founder and writer behind FitlyFast. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you are crammed in a small kitchen, a dorm room, or an RV, finding the right 3 in 1 microwave air fryer convection oven means matching its specs — capacity in cubic feet, wattage for speed, and the quality of its air fryer heat circulation — to your actual cooking habits, not just the hype on the box.

How To Choose The Best 3 In 1 Microwave Air Fryer Convection Oven
These combo ovens look similar on the outside, but the cooking results vary a lot. You need to look at four main things to pick the right one.
Capacity (Cubic Feet)
This tells you how much food fits inside. A 0.9 cubic-foot model like the BLACK+DECKER is compact and good for small kitchens, but you will struggle to fit a whole chicken or a large frozen pizza. A 1.3 cubic-foot model like the West Bend or the TOSHIBA OptiChef PRO MAX gives you room for a 13-inch pizza or a sizable roast. Check your counter depth — a 1.3 cu ft model can be 21 inches wide.
Wattage (Speed and Power)
Don’t get confused by the power numbers. You care most about the microwave wattage and the convection wattage separately. 900-watt microwaves (like the FRIGIDAIRE and BLACK+DECKER) heat food reliably, while 1000-watt microwaves (like the West Bend and TOSHIBA) give you more microwave power. For air frying and baking, convection wattage matters more: 1500W on the FRIGIDAIRE works fine, while the TOSHIBA 6-in-1 is listed at 1800W.
Air Fryer Design
Not all air fryer modes work the same way. Some models (like the West Bend) use a rotating turntable that moves food through the hot air, which buyers report yields crispier results. Others use a fixed top fan and heating element (like the TOSHIBA OptiChef PRO MAX’s ChefFry Plus). A top-fan system usually circulates heat more evenly without shifting food around. Check the reviews for specific complaints about uneven cooking or slow air fry times.
Inverter Technology vs. Standard
A standard microwave cycles on and off at lower power settings, which can overcook edges while the center stays cold. Inverter technology (found in the TOSHIBA models, Breville, and Panasonic) delivers a steady stream of power at any level. This is a big deal when you defrost meat — inverter models heat evenly so the outside does not start cooking before the inside is thawed.

In‑Depth Reviews
1. Breville BMO870BSS Combi Wave 3-in-1
See price on AmazonThe premium pick that thinks ahead so you don’t have to set anything.
This is the one that feels engineered by someone who actually cooks. Element IQ steers power exactly where and when needed, so frozen lasagna comes out hot in the middle without rubbery edges and fries get crispy golden without a second batch. The Power Smoothing Inverter delivers steady power, reheating pizza slices perfectly without turning them into cardboard.
It is also the quietest option: the soft-close door is 80% quieter than a standard microwave and operating noise is 50% lower. Owners mention the Fast Combi mode is excellent for dishes like quiche and empanadas, cooking them faster than a traditional oven would. The cavity is 1.1 cubic feet, slightly smaller than the West Bend’s 1.3 cubic feet, but the trade-off is build quality — reviewers consistently mention the heavy, solid feel and the stainless steel interior that wipes clean easily. Just know that the air fryer mode preheats for about three minutes each time you open the door, and the grill function is not as straightforward for some users.
Where It Shines
- Element IQ smart power steering for even cooking
- 80% quieter soft-close door and quiet operation
- Inverter technology for gentle defrosting without cooking edges
- 19 built-in smart presets and a shortcuts panel on the door
Where It Falls Short
- Air fryer preheats for a few minutes each time the door is opened during cooking
- Some customers note reliability issues with the soft-close door over time
- Higher price than many multi-function competitors
Your best bet if: you want a well-built, quiet machine that takes the guesswork out of reheating and defrosting, and you are willing to pay for the smart features.
Think twice if: you rely heavily on air frying large batches — the 1.1 cu ft cavity and small tray may feel cramped, and the grill hidden behind a button press is annoying for daily use.
2. TOSHIBA 6-in-1 Inverter Countertop Microwave Oven
See price on AmazonThe brute-force option with an 1800W power rating that is built to cook food fast.
If speed is your top priority, this Toshiba has a power rating that stands out from the crowd at 1800W, while the FRIGIDAIRE is listed at 1500W convection. In real life, that can mean stronger heating performance for browning and crisping.
The 6-in-1 functions include microwave, air fryer, convection oven, broiler, defroster, and speedy-combi mode. Reviewers point out the defrost mode works perfectly without cooking the edges, and the 27 auto menus plus 10 air fry presets make it easy for beginners. However, there is a durability concern that appears in multiple reviews: one reviewer noted the convection oven stopped working just over the 1-year warranty, with the temperature unable to exceed 100°F. At 33.75 pounds, this is also one of the heavier units you will lift onto the counter.
Where It Excels
- 1800W convection — the highest in this lineup — for fast air frying and baking
- 1000W inverter microwave delivers even heating and gentle defrosting
- Extensive auto menus (27) and air fry presets (10) for one-touch cooking
- 50dB quiet operation
Where It Disappoints
- One buyer’s convection oven failed just after 1-year warranty
- Heavy at 33.75 pounds — awkward to move or install
- Energy consumption is 1800 watts, which is higher than many competitors
Reach for this if: you want the fastest convection crisping and a quiet inverter microwave, and you are comfortable accepting the durability risk that some shoppers say.
Look elsewhere if: long-term reliability is your top concern, or if you need a lighter unit that is easy to reposition.
3. West Bend 3-in-1 Microwave Air Fryer Convection Oven
See price on AmazonThe largest cavity here uses a rotating tray to get food crispier on all sides.
At 1.3 cubic feet, this is tied with the TOSHIBA OptiChef PRO MAX for the biggest interior in the lineup, versus 0.9 cubic feet for the BLACK+DECKER. That extra space matters when you want to air fry a full batch of chicken wings or roast a whole chicken without crowding.
What sets this model apart from the others is the air frying design. Buyers specifically note that air frying on the rotating tray yields crispier results because the food moves through the hot air instead of sitting still. The 12 presets and speed defrost make daily operations simple. A common complaint is that the air fry temperature can only be adjusted in 25-degree increments using the presets, which limits fine-tuning. Some customers have also received units with bent doors during shipping, so inspect the packaging carefully upon arrival.
What Works
- Largest capacity (1.3 cu ft) of the value picks — fits large roasts
- Rotating tray air fryer gives crispier, more even results
- 1000W microwave power for faster reheating
- Touchscreen controls with 12 presets
What Does Not
- Air fry temp limited to 25-degree preset increments
- Multiple buyer reports of door damage during shipping
- Dimensions (21.3″W x 18.5″D) require significant counter space
Pick this for: larger households who need the biggest capacity and want the rotating air fry tray for consistently crispy food.
skip it if: you have limited counter depth or want freeform temperature control in the air fryer — the 25-degree preset steps might bug you.
4. Panasonic HomeChef 4-in-1 Countertop Microwave
See price on AmazonLets your phone take over so you can follow recipes without setting anything manually.
The HomeChef 4-in-1 pairs with the Panasonic Kitchen+ app to send cooking instructions directly to the oven — choose a recipe on your phone, gather ingredients, and the oven handles the microwave, broiler, air fryer, and convection modes automatically. This makes it the most convenient option if you often find yourself hunting for cook times. The 1000W inverter microwave ensures even defrosting and reheating, and the 1.2 cubic foot cavity fits a standard frozen pizza with room to spare.
Buyers mention the air fryer yields crispy, brown results on chicken nuggets and wings, and the touchscreen is responsive once you get past a short learning curve. A notable design quirk: the child lock can only be unlocked by pressing “Timer/Clock,” and it resets after a power outage, which some owners find frustrating. The air fryer also has limited temperature choices (400-425°F), so you cannot fine-tune the heat for delicate items.
Strong Points
- Kitchen+ app sends recipes and cooking instructions directly to the oven
- Genius inverter technology prevents over- or under-cooking
- Large 1.2 cu ft capacity with small overall footprint (22″W x 17.7″D)
- 4-in-1 functions: microwave, broiler, air fryer, and convection oven
Weak Points
- Air fryer temperature limited to 400-425°F presets
- Child lock resets after power loss and requires a specific button-press to unlock
- Glass turntable rotates in all modes, which can limit usable height for tall items
Go for this if: you want an app-guided cooking experience and the versatility of four appliances in one tidy package.
Pass if: you hate using a phone to control your kitchen gear, or you need precise air fry temperature control for recipes that call for specific heat.
5. SAMSUNG 1.2 cu. ft. Countertop Convection Microwave with Air Fry
See price on AmazonA sleek smart oven that pairs with your voice assistant and checks in via app.
Samsung brings its smart home ecosystem into the kitchen with this 1.2 cubic-foot model. You can monitor and control it remotely using the SmartThings App, or just ask Bixby, Amazon Alexa, or Google Assistant to check the status or start cooking. The Power Convection distributes heat thoroughly and cooks up to 30% faster than standard convection, per the manufacturer. The PowerGrill Duo browns and crisps food on the outside without drying it inside.
Buyers report the 15-inch turntable fits comfortably inside the 1.2 cu ft cavity, and the drop-down door helps when you are pulling out a hot dish. However, some owners have experienced reliability issues: one review says the grill and air fryer elements did not generate sufficient heat, and the microwave eventually failed to heat food altogether. The 900W output is on the lower end compared to the 1000W models from West Bend and TOSHIBA, so expect slightly longer cook times for microwave-only tasks.
What You Gain
- Wi-Fi connectivity with SmartThings App and voice control via Alexa, Google Assistant, or Bixby
- Power Convection cooks up to 30% faster than standard convection
- PowerGrill Duo for browning and crisping without drying
- Drop-down door design for easy access
What You Risk
- Multiple buyer reports of grill and air fryer elements failing to generate enough heat
- 900W microwave output is lower than most competitors
- Non-removable broiler element makes the top of the cavity harder to clean
Choose this if: you are already invested in the Samsung SmartThings ecosystem and want voice control for your cooking.
Avoid if: consistent heating performance is non-negotiable — the reliability reports from buyers are hard to ignore at this price point.
6. TOSHIBA OptiChef PRO MAX Air Fryer Combo Microwave Oven
See price on AmazonThe flashiest interface in the bunch with a color screen and Alexa built in.
This Toshiba stands out immediately with its 2.4-inch colorful screen that makes navigating the 1100W microwave and air fryer settings feel modern and intuitive. The ChefFry Plus system uses a top fan and heating element that replicates an air fryer oven, delivering healthier cooking without needing to shake a basket. The humidity sensor ensures even heating and retains moisture, so chicken stays juicy inside while the outside crisps. At 1.3 cubic feet, it accommodates a 13-inch pizza or a whole chicken easily.
Buyers love the speed of the air fryer and the even defrosting from the Inverter technology. However, one reviewer reports a critical failure: the device died after 4.5 months, with steam causing a power failure. Another notes that the microwave output feels weaker than 1100W, leaving some food undercooked at standard times. The ceramic enamel interior is easier to wipe down than stainless steel, but the interior height is limited (9.3 inches), so tall dishes may not fit under the top heating element.
Strengths
- 2.4-inch color screen with intuitive interface for easy navigation
- ChefFry Plus top-fan system for even, fast air frying
- Humidity sensor retains moisture and prevents over- or under-cooking
- Alexa compatible for voice control
Weaknesses
- One buyer reports the unit died after 4.5 months due to steam damage
- Some users feel the 1100W microwave output is weaker than expected
- Limited cavity height (9.3 inches) may not fit taller dishes
Best for: tech-savvy cooks who want a color display, voice control, and a sensor that does the timing for them.
Not for: anyone who needs a proven long-term track record — the reliability data is too thin to guarantee years of use.
7. FRIGIDAIRE 1.2 cu ft Microwave, Digital Air Fryer, Convection Oven, Combo-Fry
See price on AmazonA value-forward workhorse that bakes, roasts, and air fries while staying affordable.
The Frigidaire packs a lot of function into a stainless steel body at a price that undercuts many competitors. The 900W microwave, 1000W oven, and 1500W convection modes give you three distinct cooking methods, and the 1.2 cubic foot capacity fits a standard frozen pizza or a small roast. The five one-touch cook menus — Potato, Popcorn, Beverage, Reheat, and Frozen Dinner — keep daily operation simple.
Buyers generally like the air fryer, calling it “awesome,” but there are some significant complaints. One reviewer reports it stopped working after four weeks, stating it “stopped working after 4 weeks, will not heat food up.. It worked wonderfully when we first purchased it.” Another notes the microwave is “very noisy” when running. The separate bake plate and air frying kit are useful additions, but the lower microwave wattage (900W) compared to the West Bend or TOSHIBA models means your reheats will take a bit longer.
What You Get
- Multi-function with 1500W convection for baking and roasting
- 1.2 cu ft capacity at a lower price than most competitors
- Includes air frying kit and bake plate
- Five one-touch cook menus for convenience
What You Give Up
- Several buyer reports of early failure within weeks of purchase
- Noisy operation during microwave use
- 900W microwave is less powerful than 1000W models
Suitable if: you are on a tight budget and want a multi-function oven with a large capacity and 1500W convection.
Warning: the durability complaints are frequent enough that you should consider an extended warranty or be prepared to return it.
8. BLACK+DECKER 5-in-1 Microwave Oven with Air Fry
See price on AmazonThe tiny but capable option that fits in tight spots and knows how to cook frozen snacks.
If your counter space is a premium, the BLACK+DECKER’s 0.9 cubic foot footprint (15.55″D x 19.49″W) is the smallest in this lineup. It is a proper 5-in-1 that microwaves, air fries, bakes, roasts, and runs a combi mode. The 900-watt output is enough for basic reheating, and the 11 air fry presets — including French fries, chicken wings, and spring rolls — make it easy to get started. One buyer reports the “Air fryer works well for crispy food.”
The trade-off is that lower power and smaller interior mean it takes longer to heat large dishes, and you cannot fit a whole chicken or a standard 13-inch pizza. Some reviewers also note the door opens differently, occasionally pulling the unit forward, which can be annoying. The child-lock feature is a nice safety touch, activated by holding the stop button for three seconds.
It Excels At
- Very compact dimensions fit small kitchens, dorms, or RVs
- 11 air fry presets for frozen snacks and vegetables
- 5-in-1 cooking functions in one appliance
- Easy-to-use controls and child lock
It Struggles With
- 0.9 cu ft is too small for large dishes, whole chickens, or big pizzas
- 900W microwave is less powerful than most competitors, leading to longer cook times
- Door design can cause the unit to slide forward when opened
Go for it if: you are outfitting a small space and need a compact, affordable multi-function oven that handles frozen food and basic cooking.
Pass if: you often cook for more than two people or want to fit a full-size pizza — the 0.9 cu ft will feel cramped.
9. Breville USA RM-BMO870BSS1BUC1 (Renewed)
See price on AmazonGet the same premium Breville features for less, as long as you accept the refurbished risk.
This is the certified remanufactured version of the Breville Combi Wave 3-in-1, and it brings all the same smart cooking features at a lower cost. You get the Element IQ system, the Power Smoothing Inverter, the Fast Combi and Cook from Frozen functions, and the 19 built-in smart presets. The 1.1 cubic foot capacity is identical to the new model, and it includes the Combi Crisp Pan, trivet, and instruction booklet.
Buyers who have purchased this renewed unit report it shows limited or no wear, and the six-month Breville Limited Warranty provides some confidence. The soft-close door, stainless steel interior, and intuitive controls are all present. However, as a refurbished unit, it does not carry the full 1-year warranty of the new model, and you may encounter cosmetic imperfections. One buyer of the new model mentioned the door soft close can break, so inspect the hinge carefully when you receive a renewed unit.
Why Buy Refurbished
- Same premium Breville features (Element IQ, Inverter, Fast Combi) at a lower price
- Includes all original accessories (Combi Crisp Pan, trivet)
- Six-month warranty from Breville
- Soft-close door and quiet operation
Why Think Twice
- Only six months of warranty compared to the new model’s 1 year
- May have minor cosmetic wear from previous use
- Design flaws like the door soft-close mechanism are not fixed in this version
Consider this if: you want the top-tier smart cooking features but your budget does not stretch to the full-price new model.
pass on it if: you want the full manufacturer warranty and a pristine unit with no signs of previous ownership.
Understanding the Specs
Microwave Wattage (Output)
This number (usually 900W or 1000W in this category) tells you how much microwave energy hits your food per second. Higher watts generally mean faster reheating and better penetration into dense items like a frozen dinner. If you mostly reheat leftovers and microwave popcorn, 900W is fine. If you defrost raw meat or cook full meals, 1000W gives you more microwave power.
Convection Wattage (Air Frying Heat)
This tells you how much power goes into the heating element that drives the air fryer and oven functions. A 1500W convection system like the FRIGIDAIRE’s does a good job roasting vegetables and baking cookies. The TOSHIBA 6-in-1 is listed at 1800W, while the FRIGIDAIRE is listed at 1500W. That higher listed wattage can help with browning and crisping when you are cooking multiple batches.
Inverter vs. Standard Microwave
A standard microwave turns the magnetron on and off at lower power levels — at 50% power it blasts full heat half the time and does nothing the rest, which can overcook the edges of a dish. Inverter technology delivers a continuous, adjustable stream of power at any level, so defrosting a steak cooks the center without turning the outside gray. If you defrost frequent raw proteins or reheat delicate sauces, an inverter model (TOSHIBA, Breville, Panasonic) is worth the premium.
Capacity (Cubic Feet)
This measures the interior volume. A 0.9 cu ft model is compact and fits a 10-inch pizza or a small casserole dish. A 1.2 or 1.3 cu ft model fits a 13-inch pizza, a whole chicken, or a 9×13 baking dish. However, bigger capacity often means a larger footprint on your counter — the West Bend is 21.3 inches wide. Measure your available counter space before you buy, and remember that you need a few inches of clearance around the unit for ventilation.
