The Hidden Flaw in Singapore Kitchens

Many Singapore homeowners invest in expensive kitchen hoods only to find lingering sambal smells and oily residue on their furniture just weeks later. The reality is that most homes use recirculating hoods that simply filter grease but push the smell back into the room. At BRU Room, we help to direct airflow to ensure your home stays truly fresh.


How an Engineered Ducting System Works

Using our "Plan First" approach, we ensure every installation follows a strict 5-step airflow logic to solve persistent cooking odors:

  1. High-Velocity Capture: Smoke, grease, and fumes are captured immediately at the hood source before they can spread to your living area.


  2. Secondary Filtration: An additional filter reduces grease particles before air enters the duct, preventing long-term buildup and maintaining system performance


  3. Flexible Precision Connection: We use specialized connectors to transition airflow from the hood into the main duct system, minimizing resistance.


  4. Concealed Routing Design: We design rigid ducts that run discreetly through cabinet shadow gaps or false ceilings. We optimize the number of bends, as every 90-degree turn significantly reduces effective suction.


  5. External Exhaustion: Finally, air is discharged through an external vent, ensuring oily air is removed from the home entirely.


Is Kitchen Ducting Legal in Singapore?

A common concern for BTO and HDB owners is legality. Kitchen ducting is permissible in Singapore provided it adheres to specific ventilation and building guidelines. Our process begins with a Feasibility Evaluation to ensure all routing is compliant with HDB and Condo regulations before any work begins.
