If you’re planning a kitchen remodel or building a custom hood enclosure, you’ve probably wondered: “What is a vent hood insert, and do I need one?”
A vent hood insert is one of the most important components of a high-performance ventilation system—and it gives you the freedom to design a kitchen hood that fits your style perfectly.
This guide breaks down what a vent hood insert is, how it works, and why it’s become a top pick for homeowners who want both power and aesthetic flexibility.
What is a Vent Hood Insert?
A vent hood insert is the internal ventilation unit—containing the blower, fan, controls, lighting, and filters—that fits inside a custom-built hood enclosure.
Unlike traditional range hoods, a vent hood insert does not come with a visible chimney or exterior shell.
Its main job is to remove:
- Smoke
- Grease
- Odors
- Steam
- Heat
- Airborne particles
By installing the insert inside a custom hood, you get both pro-level ventilation and full control over the exterior design.
How a Vent Hood Insert Works
A vent hood insert operates like a standard cooker hood, but installed inside your custom housing:
- Smoke & fumes are pulled in from the cooktop.
- Filters trap grease and particles (usually baffle or mesh filters).
Depending on your setup, air is either:
Ducted outside for maximum ventilation, or recirculated into the kitchen after passing through charcoal filters (ductless option).
Vent hood inserts come in several configurations:
Ducted Vent Hood Inserts
Best for heavy frying, wok cooking, and large gas stoves. They vent all smoke outdoors.
Ductless Vent Hood Inserts
Ideal for apartments or kitchens without ductwork. They use charcoal filters to clean the air.
Remote Blower Inserts
Place the blower in an attic or outdoors for super-quiet performance.
Benefits of Installing a Vent Hood Insert
Homeowners and designers choose vent hood inserts for several reasons — and it’s not just aesthetics.
1. Full Design Freedom
You can create any style of hood exterior:
- Wood
- Stainless steel
- Plaster
- Stucco
- Stone
- Tile
- Copper or brass finishes
Whether you want a farmhouse look or a modern sculptural hood, the insert gives you total flexibility.

2. Superior Air Quality
Vent hood inserts eliminate grease, fumes, and contaminants, protecting walls and cabinetry from buildup.
3. Space-Saving Integration
The insert sits neatly inside your custom housing or cabinetry without taking up extra room.
4. Quieter Ventilation
When paired with a remote blower, inserts can be significantly quieter than traditional hoods.
5. Better Lighting
Integrated LED lighting improves visibility and enhances the cooking area ambiance.
Common Vent Hood Insert Sizes
36 Inch Vent Hood Insert
Best for 30–36 inch cooktops. It provides wider coverage, making it perfect for frequent cooking, high heat, and heavy smoke removal.
30 Inch Vent Hood Insert
The 30-inch vent hood insert is the most popular size for standard U.S. kitchens. It fits most 30-inch ranges and offers reliable airflow for everyday cooking without occupying too much cabinet space.
20 Inch Vent Hood Insert
A 20-inch vent hood insert is designed for compact kitchens, small apartments, and limited cabinet spaces. It provides essential ventilation in tight areas while maintaining a built-in, streamlined look.
Why Choose CIARRA Built-In Vent Hood Inserts?
Ciarra’s vent hood inserts are designed for homeowners who want powerful, professional ventilation without sacrificing cabinet space or kitchen aesthetics. Each model combines strong suction, durability, and flexible installation to fit both compact and full-size kitchens. Whether you cook light meals or heavy, oily dishes, Ciarra offers the right CFM level, filter system, and smart features to match your needs.
Below is an overview of the three key models—and why they are highly recommended.
CIARRA Professional Series 36-inch Range Hood Insert for Gas Stoves – 950 CFM (CAS36928A-OW)
Best for: Large cooktops (30–36 in), heavy cooking, oily fumes, wok cooking, grilling, and busy family kitchens.
The CIARRA Professional Series 36" insert is designed for homeowners who demand commercial-level ventilation, especially those cooking on high-heat gas stovetops. Its 950 CFM professional suction quickly captures grease, smoke, steam, and combustion byproducts generated from intense cooking—making it ideal for searing, frying, wok cooking, and daily family meals.

A standout feature is the built-in gas leak detection sensor, which provides an extra layer of safety for households using natural gas or propane. If unusual gas levels are detected, the hood alerts you immediately, offering peace of mind while cooking.

The hood features a 4-speed motor with a Boost mode, letting you adjust airflow from gentle simmering to maximum extraction during heavy oil cooking. It supports dual ventilation modes:
Ducted mode for maximum performance.
Ductless mode with the optional Plasma⁺ System, which purifies air without the need for filter replacements.
Convenience features include dishwasher-safe baffle filters, a modern touch panel, and full smart control options such as Alexa, Google Home, and the Smart Life App. Constructed with premium 304 stainless steel, it resists rust, heat, and corrosion for long-term durability.

Why We Recommend It
This is CIARRA’s most powerful built-in model and the best choice for large households, frequent cooks, and anyone who wants strong ventilation hidden neatly inside cabinetry. With its 950 CFM airflow, smart controls, and advanced safety features, it delivers exceptional performance and reliable air purification—especially for gas stove users who need efficient removal of smoke and fumes.

2. CIARRA 29 inch Range Hood Insert – 450 CFM (CAB75913E-OW)
Best for: 24–30 in cooktops, light to moderate cooking, apartments, condos, small kitchens
Why This Model Stands Out
- 450 CFM suction: Ideal for everyday tasks like pan-frying, sautéing, simmering, and moderate oil use.
- Mechanical push-button control: Simple, durable, and easy to use.
- Durable cast aluminum motor housing: Stable and long-lasting.
Two ventilation options:
- Ducted for stronger performance
- Ductless with carbon filters (replace every 2–4 months)
- 5-layer aluminum mesh filter: Dishwasher-friendly and effective at trapping grease.
- Energy-saving LED lighting for improved visibility.
Why We Recommend It
This is a perfect budget-friendly choice that doesn’t compromise performance. At 450 CFM, it’s strong enough for most American cooking styles while staying quiet and compact. Great for cabinet integration in smaller homes.

- Energy-efficient LED lighting for clear cooking visibility.
Why We Recommend It
If space is your biggest concern, this 20-inch model is one of the most compact but capable inserts available. It delivers the same suction power as the 29" model but fits where other range hoods cannot.

How to Install Vent Hood Insert
To install a vent hood insert, follow these basic steps:
1. Measure and Prepare the Cabinet Opening
Ensure the insert fits your custom cabinet or hood liner. Mark the cutout area and create the opening if needed.
2. Install the Hood Liner (if required)
Many inserts need a metal hood liner box to protect the wood cabinet from heat and grease.
3. Secure the Insert
Lift the vent hood insert into the opening and fasten it using the mounting brackets or screws provided by the manufacturer.
4. Connect the Ductwork
Attach the vent pipe securely if using a ducted setup. Seal all joints with foil tape to prevent air leaks.
For ductless installation, install the carbon filters according to the manual.
5. Make Electrical Connections
Connect the wiring to a dedicated power supply. This step is best handled by a qualified electrician if you’re not experienced.
6. Test the Unit
Turn on the lights and fan to ensure everything functions correctly.
