Cooktops with Filter-Based Ventilation System: The Chimney-Free Revolution

Updated: Jun 3

In the constant quest to improve the functionality and design of modern kitchens, one of the most notable advancements in recent years has been the implementation of filter-based ventilation systems that do not require a chimney. These systems offer an innovative and efficient solution to keep our kitchens free of smoke and odors without the complications of a traditional installation. In this blog, we will explore how these systems work, their advantages, and some of the most popular options on the market.

What is a Filter-Based Ventilation System?

A filter-based ventilation system is a device designed to eliminate smoke, vapors, and odors from the kitchen. Unlike traditional range hoods that require a chimney or duct to expel the air outside, these systems use advanced filters to purify the air and then recirculate it within the kitchen.

How Do They Work?

These systems generally consist of three main components:

  1. Air Extractor: This component draws in the contaminated air generated during cooking.

  2. Filters: These may include grease filters, activated carbon filters, and HEPA filters, which work together to capture grease particles, eliminate odors, and purify the air.

  3. Recirculation: Once filtered, the clean air is returned to the kitchen, maintaining an environment free of contaminants without the need for an external exhaust duct.

Advantages of Filter-Based Ventilation Systems

  1. Ease of Installation: No need to drill walls or install ducts, greatly simplifying installation and reducing costs.

  2. Design Flexibility: They allow greater freedom in kitchen design, as they are not limited by the location of a chimney. This is especially useful in apartments or buildings where structural modifications are difficult.

  3. Energy Efficiency: These systems are often more energy-efficient since they do not extract heated or cooled air from the home, helping to maintain a constant indoor temperature.

  4. Easy Maintenance: The filters are generally easy to remove and clean or replace, facilitating regular maintenance.

  5. Sustainability: By not expelling air outside, they help reduce environmental pollution and can contribute to a more eco-friendly kitchen.

Popular Options on the Market

The market offers a variety of filter-based ventilation systems, ranging from high-end models to more affordable options. Here are some of the most recognized brands and models:

  1. Bora Basic: Known for its innovative surface extraction system, where the extractor is integrated into the cooktop, efficiently eliminating fumes right at the source.

  2. Elica NikolaTesla: Combines a sleek induction cooktop with a powerful central ventilation system, ideal for modern and minimalist kitchens.

  3. Falmec Quasar: Offers an aesthetically pleasing design with advanced filtration technology that ensures excellent air purification.

  4. Siemens iQ700: Features a ductless solution with long-lasting activated carbon filters, perfect for homes seeking a combination of functionality and design.

Maintenance Tips

To ensure the optimal performance of a filter-based ventilation system, it is crucial to follow some maintenance tips:

  • Regular Cleaning: Grease filters should be cleaned regularly, ideally every two weeks, to prevent residue buildup.

  • Replacement of Carbon Filters: These filters have a limited lifespan and should be replaced according to the manufacturer's recommendations, typically every 6 months to a year.

  • Technical Inspections: Performing periodic technical inspections can help identify and resolve any issues before they affect the system's performance.


Filter-based ventilation systems represent an innovative and efficient solution for modern kitchens. They offer multiple advantages in terms of installation, design, energy efficiency, and sustainability. By choosing the right system and maintaining it properly, it is possible to enjoy a clean, smoke-free kitchen environment without the complications of traditional chimney installations. If you are renovating your kitchen or simply looking to improve the air quality in your home, consider this versatile and high-tech option.
