Understanding Range Hoods: Essential Guide for Your Kitchen

The cooker hood is a vital yet often overlooked component in kitchen design. Whether you're renovating or enhancing your kitchen's functionality, understanding the role and types of range hoods is essential. This guide delves into the purpose, operation, key components, and various types of range hoods to provide you with a comprehensive understanding.

What is a range hood?

A  range hood, also known as a vent hood, kitchen hood, or extractor hood, is a critical kitchen appliance designed to improve indoor air quality by removing airborne pollutants generated during cooking. Installed directly above the stovetop or cooking surface, a contemporary range hood uses a built-in fan system to capture smoke, steam, grease particles, odors, heat, and even harmful gases such as carbon monoxide. Depending on the configuration, it either vents this air outdoors through a ducted system or recirculates it into the kitchen after passing it through multiple filters.

Key Features and Functions:
Powerful Ventilation: The core purpose of a range hood is to efficiently expel cooking fumes, ensuring a fresher, healthier, and more comfortable cooking environment. High-performance models offer multiple fan speeds and advanced airflow systems measured in CFM (cubic feet per minute). But that doesn't mean you're choosing a high CFM for the most effective removal of fumes. We still recommend that you select a range hood with a high air speed to really clean the air in your kitchen and protect your breathing health! 

Air Filtration: A stylish range hood typically include grease filters (often aluminum or stainless steel mesh) to trap oil particles, and charcoal filters in ductless models to neutralize odors and smoke. Some high-end models also feature HEPA filters or plasma filters for advanced air purification.

Integrated Lighting: Most modern range hoods are equipped with LED or halogen lighting to provide clear visibility of the cooktop area. Some models allow for adjustable brightness levels, improving both safety and visual precision while cooking.

Noise Control: Advanced models offer ultra-quiet operation, with sound levels measured in sones or decibels, making them suitable for open-concept kitchen layouts.

Smart Features: High-tech range hoods may include touch controls, digital displays, auto-sensors (that adjust fan speed based on smoke levels or heat), Wi-Fi connectivity, and even voice control via smart assistants like Alexa or Google Assistant.

Design Versatility: Range hoods come in various styles—wall-mounted, under-cabinet, island, ceiling-mounted, downdraft, and insert/liner hoods for custom cabinetry. Materials range from stainless steel and glass to copper and matte finishes, allowing for seamless integration into any kitchen design.

Venting Options:

Ducted Range Hoods: These vent air to the outside, offering superior air removal but requiring proper ductwork.

Ductless (Recirculating) Range Hoods: These clean the air through internal filters and recirculate it back into the kitchen—ideal for apartments or spaces where external venting isn’t possible.

Having these features makes the range hood not only a functional necessity, but a cornerstone of a healthy, efficient and enjoyable cooking environment. Whether you’re a casual home cook or a serious culinary enthusiast, investing in a quality range hood can significantly reduce airborne contaminants, extend the life of your kitchen surfaces, and enhance overall kitchen comfort and safety. With innovations in design, filtration, and smart technology, modern range hoods have evolved to meet the demands of today’s high-performance kitchens.

How Does a Range Hood Work?

Range hoods operate on the principle of mechanical ventilation, using fans to create negative pressure that draws contaminated air upward. Here’s a step-by-step breakdown:

1. Capture Phase

As heat rises from cooking, the hood’s canopy or capture area traps airborne particles. Wider hoods generally offer better capture efficiency.

2. Filtration

Ducted Systems: Air passes through metal grease filters (typically aluminum or stainless steel mesh) that trap 90–95% of grease particles. The filtered air then travels through ductwork to the outdoors.

Ductless Systems: Air circulates through charcoal or carbon filters to neutralize odors before recirculating it back into the kitchen.

3. Exhaust/Recirculation

Ducted hoods expel contaminants outside, requiring exterior venting.

Ductless models rely on activated carbon filters but are less effective at removing heat and humidity.

4. Air Replacement

As contaminated air is removed, makeup air enters the kitchen through gaps in windows, doors, or dedicated vents to balance pressure.

Key metrics determining performance include:

CFM (Cubic Feet per Minute): Measures airflow power. A good rule of thumb is 1 CFM per 100 BTU of your gas range. For frequent cooking, aim for a hood with at least 350 CFM. However, higher CFM levels can lead to increased noise.

Noise Level: Measured in sones; lower values (<3 sones) indicate quieter operation.

How CleaDeep Range Hood Works

The CleaDeep IQV P1 range hood is equipped with cutting-edge Inclined Quad-Vortex Technology, delivering unmatched smoke, odor, and PM2.5 control through a powerful three-stage mechanism: Grab, Extract, and Shield.

Unlike conventional range hoods that focus solely on airflow, CleaDeep redefines kitchen ventilation by using aerodynamic design and advanced fluid dynamics to trap, extract, and block pollutants—right at the source.

1. Grab – Cyclonic Capture at the Source

Using aerodynamic principles, CleaDeep generates four counter-rotating low-pressure cyclones above the cooktop. These micro-cyclones act like precision vacuum traps, instantly capturing smoke, odors, and fine particles before they escape into the surrounding air.

• Source-based capture

• Exchange prevention

• Low-pressure concentration

With a pressurized air inlet and a high-speed BLDC motor generating wind speeds up to 13 m/s, the system works in tandem with dual side glass deflectors to channel airflow. This setup creates powerful inward-rotating vortices that pull in pollutants from the cooking zone, locking them down before they can spread.

2. Extract: High-Speed Slant Vent for Instant Suction

Harnessing the Coandă effect, the CleaDeep IQV P1 creates a high-velocity rear-angled airflow that carries smoke and PM2.5 particles swiftly away from the cooking zone, forming a clean-air “Golden Breathing Triangle” around the user.

• 13 m/s high-speed airflow

• Coandă effect utilization

• Golden Breathing Triangle

This jet-like suction is 3–5 times faster than standard hoods, enabling ultra-efficient smoke extraction and keeping the air around the cook consistently clean.

3. Shield – Air Curtain Technology for Secondary Containment

To ensure nothing escapes, CleaDeep features a push-pull airflow system with a soft air curtain that creates a secondary containment zone. This blocks cooking fumes from mixing with ambient air—even during intense stir-frying.

• Push-pull intake structure

• Secondary capture zone

• Leakage prevention

Strategically placed at the top left and right of the unit, the air curtain prevents smoke from leaking out of the outlet area, providing complete protection even under heavy-load conditions.

Instead of traditional range hoods that rely on cluttered grease filters, CleaDeep uses high-speed centrifugal force to separate grease from the air. A self-cleaning air film forms on the blower surface, reducing grease adhesion—even without a filter.

With zero-filter, zero-maintenance design and real-time PM2.5 control, the CleaDeep IQV P1 not only keeps your kitchen clean, but also protects your health by minimizing exposure to harmful airborne particles.
