People use many names for the same appliance. That is why a simple buying decision can feel more confusing than it needs to be.
-
Kitchen hood
-
Chimney
-
Extractor
In Indian homes, most people say “kitchen chimney”. Whatever you call it, the purpose is simple. A kitchen hood sits above the cooktop and helps capture smoke, steam, smells, and airborne grease.
If you are renovating, the number of shapes and names can feel confusing. This guide explains the hood types you will actually see in Indian homes, what they are used for, and how to choose one without guesswork.
At Kaff, we build chimneys for Indian kitchens. The examples in this guide are written with the Kaff range and Indian cooking in mind.
A Note on Terms
Many people search for kitchen hoods and then get confused because shops and installers use different words. In India, “kitchen chimney” is the most common term. In other markets, you will hear “range hood” or “extractor hood”. This guide uses these terms in a simple way.
-
“Kitchen hoods” means the category.
-
“Chimney” is the common Indian name for the same appliance.
The choice and installation logic stays the same. Layout and ducting still decide most results.
1. The Two Main Hood Layouts
Most kitchen hood choices start with one question. Where is your cooktop placed?
Wall mounted hoods
If your hob is against a wall, you will typically choose a wall mounted chimney. This is the most common setup in Indian homes.
Wall mounted chimneys can come in different looks. The common ones include:
-
Straight line and box styles
-
Curved glass styles
-
Inclined styles
These are style variations. The core layout is the same. The hood is mounted on the wall above the hob, and ducting is usually routed upwards and out.
Island hoods
If your hob is on an island, you need an island chimney. Island chimneys are designed to be visible from every side and are suspended from the ceiling. Island setups need early planning because the duct route usually runs through the ceiling.
Kaff offers island chimneys. If you are planning an island kitchen, treat the chimney as part of the ceiling plan, not as an add-on.
2. Ducted vs Ductless: What It Means
After layout, the next choice is whether the hood vents outside. This is a practical decision that affects installation and maintenance.
Ducted hoods
A ducted chimney moves air out of the home through a duct. It is the most direct way to remove smoke and smell from the kitchen.
This approach is often preferred in homes that cook daily. It is also common when:
-
You cook regularly
-
You fry often
-
You want smoke and smell removed from the home rather than recirculated
A ducted setup also needs duct planning. A long route with many bends can reduce performance.
Ductless hoods
A ductless hood filters air and releases it back into the room. This is used when venting outside is difficult due to building constraints. Kaff lists ductless island options on select models. If you are considering ductless, confirm:
-
What filter system the model uses
-
How it is maintained
-
What parts need replacement
Kaff’s warranty guidance also includes maintenance information for items such as charcoal filters where applicable. If you are choosing ductless, this is one of the first things to check.
3. Styles: What the Shapes Actually Change
Many hood names are really about appearance. A good looking hood can still underperform if the size or installation is wrong. Here is what style affects in real use.
Curved glass
Curved glass designs are popular in modern kitchens. They can look light and elegant. They can also show fingerprints and smudges clearly, especially on darker glass.
Straight line and box styles
These styles tend to look clean and simple. They often suit kitchens where you want the hood to blend with cabinets.
Inclined styles
Inclined chimneys are mounted at an angle. Many people choose them for extra headroom while cooking. As with any style, check size coverage and airflow ratings for the exact model.
4. The Features That Matter More Than Shape
If you want a hood that feels good in daily use, focus on these practical features. They decide comfort once the novelty of a new kitchen wears off.
Airflow rating
Airflow or suction figures are the core performance numbers. Kaff publishes airflow figures on many chimney product pages. Use those figures to compare models.
If you cook lightly, you may not need the highest airflow model. If you fry often or use multiple burners regularly, choose a model designed for heavier use.
Noise
Noise depends on the model, the speed you use, and your duct route. If a noise rating is listed, use it as one comparison point. A direct duct route can also help reduce noise by reducing resistance.
Motor type
If you cook daily, motor type can affect day to day comfort. Some chimneys list BLDC motors. BLDC stands for Brushless Direct Current, and it is a motor design that can support smoother speed control and lower power draw at everyday settings, depending on the model.
Grease handling: filters and filterless designs
Grease is the real test in Indian kitchens. If a hood struggles with grease, the kitchen starts to feel grimy no matter how nice the cabinets are.
Kaff offers different grease handling approaches across models. Depending on the model, you will see:
-
Baffle filters on select models
-
Filterless technology on select models
-
Oil collectors on select models
Choose a design that matches your routine. If you will not clean often, a design that makes grease handling easier is usually a better fit.
Auto clean
Some Kaff models list auto clean features, described as dry heat auto clean or smart auto clean. Auto clean can make maintenance easier, but it does not remove the need to clean surfaces and collectors. Confirm the exact method on the model page.
Controls
Controls affect habits. Kaff offers different control styles across models, including touch panels, gesture control on select models, and push button controls on select models. If you cook with messy hands often, gesture control can be convenient. If you prefer a simple interface, push buttons can feel familiar.
5. Sizing: The Rule That Stops Most Problems
Many people under-size the chimney. A practical rule is simple.
-
The hood should be at least as wide as the cooktop.
Kaff offers multiple chimney widths across models. If your hob is wider, match the chimney width to the hob.
6. Installation: Where Hoods Win or Lose
A good hood can feel weak if installation fights it. This is where many buyers lose performance without realising it.
Plan the duct route
For ducted setups, the duct route matters as much as the hood. Keep it simple:
-
Keep the route as direct as your kitchen allows.
-
Avoid unnecessary bends.
Match the duct size to the outlet
Do not reduce duct size to fit an existing hole. Match the duct size to the outlet size listed for the model.
Plan the chimney early in a modular kitchen
In modular kitchens, the chimney affects cabinet design. Choose it early so the duct cover, cabinet cut-outs, and power point can be planned neatly.
7. Maintenance: Keep It Working Like New
All chimneys need maintenance. If grease builds up, airflow drops. Then people increase speed, which increases noise. Kaff publishes maintenance guidance as part of its warranty information, including suggested cleaning intervals for items such as metal filters and oil collectors.
If your model uses charcoal filters, Kaff’s warranty guidance also references replacement intervals. Follow the guidance for your exact model.
8. A Quick Glossary for Kitchen Hoods
When you compare kitchen hoods, you will see certain terms repeated. Here is a plain-language glossary.
-
Airflow or suction: how much air the hood can move. Compare this figure across models.
-
Ducted: air is vented outside through a duct.
-
Ductless: air is filtered and returned to the room. These models depend on filter maintenance.
-
Duct cover: a cover that hides the duct pipe, often used in modern kitchens.
-
Filterless: a design where grease is handled inside the chimney and directed to an oil collector, depending on the model.
-
Baffle filter: a washable filter design used in many chimneys to handle greasy cooking.
-
Oil collector: a cup or tray where collected grease gathers.
-
Auto clean: a feature on select models designed to make grease handling easier. It reduces manual scrubbing, but routine cleaning is still required.
-
BLDC motor: a motor type listed on some models. In simple terms, it can support smoother speed control and lower power draw at everyday settings, depending on the model.
If you keep these terms clear, comparing kitchen hoods becomes much easier because you are comparing practical functions, not marketing labels. It also helps when you are browsing kitchen hoods online. You can scan product pages faster and shortlist models based on layout, ducting, and cleaning needs rather than only photos. It saves time and avoids expensive mistakes.
Conclusion
A kitchen hood choice is mostly about kitchen layout. Start there, then choose the style.
-
Hob against a wall: wall mounted chimney
-
Hob on an island: island chimney
After that, focus on what decides real performance. These basics decide whether the hood will feel comfortable in daily cooking.
-
Width coverage
-
Airflow rating
-
A duct route that is direct
-
A grease handling design you will maintain
If you keep these basics clear, the style choices become much easier. It also keeps you from paying extra for looks while compromising on capture.
Frequently Asked Questions (FAQs)
1. Is a kitchen hood the same as a chimney?
In India, most people call it a kitchen chimney. In other places, people say range hood or extractor. The appliance is the same.
2. Are ducted chimneys always better?
If you can vent outside, ducted setups often remove smoke and smell more completely. Ductless setups are used when venting outside is difficult and require filter maintenance.
3. Do island chimneys need special planning?
Yes. Island installations need ceiling planning for mounting and ducting. Plan the chimney early.
4. Do I need auto clean?
It depends on your routine. Auto clean features can make grease handling easier, but you still need regular cleaning.
5. What matters more than the hood style?
Size coverage, airflow rating, installation, and maintenance. These decide real results in a home.
