Induction cooktops with downdraft ventilation systems are a popular choice for modern kitchens, combining sleek design with powerful performance. These appliances offer an innovative solution for removing smoke, steam, and cooking odors without the need for bulky, overhead range hoods. If you're considering adding an induction cooktop with a downdraft to your kitchen, this guide will walk you through the essential factors to consider when making your purchase.
What is a Downdraft Cooktop?
A downdraft cooktop (also known as a cooktop with a downdraft ventilation system) is a type of cooking appliance that integrates both a cooking surface and a ventilation system. Unlike traditional range hoods, installed above the cooktop, a downdraft cooktop has a built-in exhaust system that pulls air downward, through the cooktop, and away from the cooking area.
This design is ideal for kitchens where a traditional overhead range hood isn’t practical or desired, such as in kitchens with low ceilings, island kitchens, or open-plan spaces. Downdraft cooktops are typically offered in both induction and gas versions, with induction models being especially popular due to their high energy efficiency and precise cooking control.
How Do Downdraft Hobs Work?
A downdraft hob works by combining the functionality of a cooktop with an integrated ventilation system that removes smoke, steam, grease, and odors directly from the cooking area.
The cooktop functions like any regular induction or gas cooktop, where you can cook your food using one or more burners or cooking zones.
The downdraft system is built into the cooktop, usually in the form of a fan and vent system located near the back of the cooktop. When activated, the fan draws air downward through the cooktop’s surface.
This airflow draws cooking odors, smoke, steam, and airborne grease directly into the vent below the cooktop.
In ducted systems, the air is then expelled outside the building through a vent.
In ductless systems, the air passes through a series of filters (often activated carbon or plasma filters) that clean the air before recirculating it back into the room.
Things to Consider When Buying An Induction Cooktop Downdraft?
When considering the purchase of an induction cooktop with a downdraft, it's important to evaluate several key features to ensure you’re choosing the right product for your kitchen needs. Here are two crucial aspects to keep in mind:
1. CADR Score (Clean Air Delivery Rate)
The CADR score is vital if you're concerned about indoor air quality, as it measures the efficiency of the air filtration system integrated into the cooktop’s downdraft. A higher CADR score means better air purification, which is essential for maintaining clean air while cooking, especially when using strong heat or frying.
What‘s the CADR?
The Clean Air Delivery Rate (CADR) is a metric used to measure the effectiveness of air purifiers, indicating the volume of clean air the device can deliver within a specific amount of time. It is a standardized method, developed through tests that date back to the 1980s, and measures the efficiency of air filtration based on the volume of air the purifier can process at maximum fan speed.
Ciarra's electromagnetic induction cooktop with an integrated range hood has a CADR score of 61.7, which indicates a strong filtration rate. In comparison to other purifiers, this score suggests that Ciarra's range hood performs well in air purification. With a CADR that beats 70% of air purifiers, you're essentially getting three key features in one: a high-performance cooktop, a powerful range hood, and an effective air purifier.

2. Plasma+ System
Another important feature to look for is the Plasma+ system, which is integrated into Ciarra's cooktops. This technology uses plasma filtration to help eliminate bacteria, harmful particles, and odors from the air. Plasma+ systems offer advanced filtration, going beyond traditional charcoal filters, providing cleaner, healthier air during cooking.

By combining the benefits of both plasma filtration and the CADR score, Ciarra's induction cooktop with downdraft becomes an excellent choice for those who prioritize clean air alongside efficient cooking.
3. Energy Efficiency
Energy consumption is another important factor when choosing an induction cooktop with a downdraft system. Induction cooktops are generally more energy-efficient than gas cooktops, as they use electromagnetic energy to directly heat the cookware, minimizing heat loss.
However, it’s also essential to consider the energy efficiency of the downdraft system. Ciarra’s downdraft cooktops have an A energy rating, which signifies high energy efficiency. This means that both the cooktop and the ventilation system work effectively without consuming excessive power, helping you save on energy bills while maintaining performance.
4. Noise Level
The noise produced by the downdraft fan is an important consideration, especially if you're sensitive to kitchen noise. The fan's noise level can vary depending on its speed and the power of the motor. Generally, downdraft systems tend to be quieter than traditional overhead range hoods. Ciarra's induction cooktop with an integrated downdraft is relatively quiet, with a fan noise level of under 62 dB, which is considered quite low compared to many other models.
5. Suction Power
When it comes to suction power, CFM (cubic feet per minute) is a critical metric. A higher CFM means stronger air extraction, which is essential for pulling smoke, grease, and odors away from the cooking area. Ciarra’s downdraft cooktops offer 600 CFM of suction power, which is impressive and ensures that the system can quickly clear smoke and cooking fumes from the kitchen, keeping the air fresh and clean.
6. Size and Installation Space
Make sure the cooktop fits the available space in your kitchen. Consider the size of the unit and whether your kitchen can accommodate both the cooktop and downdraft exhaust system.
Downdraft cooktops require installation space for the vent system, so check the product specifications to ensure it fits within the intended area.
