Whether you're an avid home chef or just want to maintain a fresh, grease-free kitchen, a reliable range hood can make all the difference. It helps eliminate smoke, odors, and airborne grease—while also enhancing your kitchen's design. But with so many styles, sizes, and features on the market, finding the right one can be challenging.
In this guide, we’ll break down the most important things to look for when buying a range hood. Whether you're upgrading or installing one for the first time, these practical tips will help you make a smart investment that fits your needs—and your kitchen.
What Is a Range Hood?
A kitchen range hood, also known as a vent hood or exhaust hood, is a kitchen appliance installed above your cooktop or stove. Its primary function is to improve indoor air quality by capturing and venting out airborne grease, smoke, steam, heat, and cooking odors generated during food preparation. By doing so, it helps prevent residue buildup on cabinets and walls while reducing the risk of mold and unpleasant smells lingering in your kitchen.
Range hoods typically consist of a canopy, a motorized fan, and a filtration system. They either vent air outside (ducted) or recirculate it back into the kitchen after filtering (ductless). Ducted systems are generally more effective, especially for households that cook frequently or use high-heat methods like stir-frying.
In addition to their functional role in kitchen ventilation, modern range hoods also contribute to the overall look and feel of your kitchen, coming in a variety of styles, materials, and finishes to match your space. Some advanced models even include smart features like air quality sensors or touchless controls. Ultimately, a well-chosen range hood enhances both your cooking experience and your home environment.

How to Choose a Range Hood That Fits Your Kitchen’s Layout
Your kitchen’s layout is one of the most important factors when selecting a range hood, as it directly influences the type of hood you can install and how effective it will be. Choosing the right style ensures both proper ventilation and aesthetic harmony with your kitchen’s design.
Under-Cabinet Hoods are the most common option, installed beneath wall-mounted cabinets above your cooktop. They’re ideal for small to mid-sized kitchens and offer a space-saving solution without sacrificing performance.
Wall-Mounted Hoods are affixed directly to the wall when no cabinetry is present above the stove. These hoods often feature sleek, modern designs and become a visual focal point.
Island Hoods are suspended from the ceiling over a kitchen island. Since they lack surrounding walls, they require higher CFM ratings and are often designed to be both powerful and stylish.
Insert or Custom Hoods are built into custom cabinetry or decorative enclosures, allowing for full design control while still maintaining strong ventilation.
Before purchasing, measure the area above your cooking surface carefully, including ceiling height, cabinet depth, and available wall space. Proper sizing and positioning will help maximize airflow and ensure your hood complements your kitchen’s layout and workflow.
What Range Hood Size Do I Need?
Your range hood should be at least as wide as your cooktop—ideally 3 inches wider on each side for maximum coverage. Standard cooktops are typically 30" or 36", so go for a 36" or 42" range hood respectively.
For island cooktops, size is even more important due to open airflow. Always size up for island hoods.

What Type of Range Hood Is Best?
When it comes to range hood ventilation, you’ll be choosing between two main types: ducted and ductless (recirculating) systems. Each has its pros and cons, depending on your kitchen layout, cooking style, and installation flexibility.
Ducted Range Hoods vent air outside through ductwork. They are widely regarded as the most effective option for removing heat, steam, smoke, grease particles, and cooking odors. Because they expel air completely from the kitchen, they provide superior ventilation and help maintain better indoor air quality—especially beneficial for frequent or high-heat cooking.
Ductless Range Hoods filter the air using charcoal or carbon filters, then recirculate it back into the kitchen. They are easier to install and don’t require access to exterior walls or ductwork. However, they are generally less powerful and need frequent filter replacements to maintain performance.
Verdict: If your kitchen allows for it, a ducted range hood is the better long-term investment. It delivers cleaner air, higher efficiency, and more reliable performance for serious home cooks.
How Noisy Is the Range Hood?
Noise is measured in sones or decibels (dB). A range hood operating between 1–3 sones (or up to 50 dB) is considered quiet.
Higher power (CFM) often equals more noise, but premium brands like CleaDeep use advanced noise-reduction technology to ensure powerful performance at a whisper-quiet level.
What CFM Should Your Range Hood Have?
CFM (Cubic Feet per Minute) measures how much air a range hood can move. The higher the CFM, the more powerful the airflow.
Here’s a simple guide:
Electric cooktops: 100 CFM per 10 inches of stove width
Gas cooktops: 100 CFM per 10,000 BTUs of burner output
For heavy cooking, wok use, or frequent frying, aim for 600+ CFM. CleaDeep range hoods go even further, offering 900 Pa static pressure and ultra-fast 13 m/s airflow to tackle the most stubborn smoke.
What Type of Filters Does the Range Hood Use?
Filters are essential in many traditional range hoods, as they trap grease, smoke, and airborne particles during cooking. The most common types include:
Aluminum Mesh Filters: Lightweight and affordable, these filters are made of layered mesh that traps grease as air passes through. However, they require frequent cleaning—typically every 2 to 4 weeks—and can be difficult to scrub thoroughly.
Stainless Steel Baffle Filters: Often found in higher-end hoods, baffle filters use curved metal panels to force air through multiple turns, separating grease efficiently. They're more durable and dishwasher-safe but can still accumulate buildup over time.
Charcoal (Carbon) Filters: Used in ductless range hoods, these absorb odors and impurities before air is recirculated. They are not washable and must be replaced regularly, usually every 3 to 6 months.
While these filters serve a purpose, maintaining them can be messy and time-consuming.
That’s why CleaDeep takes a different approach. Our innovative filter-free IQV technology eliminates traditional filters entirely. Instead, it captures and redirects grease and contaminants at the source, making the hood significantly easier to maintain. Just wipe down the collection surfaces—no soaking or scrubbing required.
Is the Range Hood Easy to Clean and Maintain?
When choosing a range hood, ease of maintenance is just as important as performance. Grease and residue can build up quickly, especially with frequent cooking, and a hood that's difficult to clean can become both unsightly and inefficient.
Look for models designed with smooth, sealed surfaces that won’t trap grime in tight corners or intricate grillwork. Features like removable grease trays or oil collectors make routine maintenance easier. If your hood includes filters, check whether they are dishwasher-safe to reduce cleaning time.
But what if you could skip filter cleaning altogether?
CleaDeep’s filter-free range hood eliminates the most frustrating part of hood maintenance—scrubbing greasy filters. Thanks to its innovative IQV technology, grease and particles are captured and channeled away from the start. Cleaning is as simple as wiping down a surface.
To make it even easier, CleaDeep includes a smart self-cleaning alert system that notifies you exactly when maintenance is needed—no guesswork, no forgotten cleanings. It’s an ideal solution for busy households that want top performance with minimal effort.
