Understanding the Basics: Ducted vs Ductless Chimney

What is a Ducted Chimney?
A ducted chimney uses a pipeline (duct) to remove air pollutants like smoke, oil particles, steam, and heat from your kitchen and release them outside. These chimneys are equipped with a motor and filters that trap grease, while the remaining air is expelled outdoors.

Key Features:
Removes smoke and steam completely
Keeps indoor air clean
Best for heavy cooking

What is a Ductless Chimney?
A ductless chimney doesn’t vent the air outside. Instead, it filters the air using carbon and grease filters and then recirculates the cleaned air back into the kitchen. These are ideal for homes where installing ductwork is difficult or not allowed (like rented apartments).

Key Features:
No external venting required
Easy installation
Filters air and recirculates it

Quick Comparison between Duct and Ductless Chimney

What are the factors to Consider Before Making a Choice ?

1. Kitchen Size and Layout
Large or open kitchens need powerful ventilation, making ducted chimneys the better choice. For Small or enclosed kitchens, especially those in apartments or rentals, may choose a ductless chimney if there is not outlet for duct or the outlet is too far. 

2. Cooking Habits
Your cooking style plays a huge role. Heavy cooking, like frying or making masala-rich dishes, creates more smoke and grease. A ducted chimney will handle this better. Light or occasional cooking can be managed efficiently with a ductless model.

3. Installation Feasibility
If you have access to external walls or space for ducting, a ducted system is feasible. If not, a ductless chimney is the only option for adequate ventilation. 

4. Maintenance Requirements
The installation cost is usually similar for both ducted and ductless chimneys. A ducted chimney requires almost no maintenance, whereas a ductless chimney needs its attachments to be replaced every 6–7 months.

FAQS

Q1. Which is better for Indian cooking—ducted or ductless chimney?
For Indian cooking that involves frying, tadka, and masala-heavy dishes, a ducted chimney is better as it removes smoke and oil fumes completely.

Q2. Can I install a ducted chimney in an apartment?
Yes, but only if your apartment allows ducting through an external wall. If ducting isn’t possible, a ductless chimney is a better option.

Q3. How often do ductless chimney attachment need to be replaced?
Attachment of the ductless chimneys should be replaced every 6–7 months, depending on cooking frequency. Grease in filters need regular cleaning every 2–3 weeks.

Yes, but only if ducting is possible. For compact kitchens without ducting options, ductless chimneys are also suitable.

Q6. Do ductless chimneys completely remove smoke?
