Cooker Hood Buying Guide 2026: What Every Homeowner Needs to Know

A cooker hood is one of the most used appliances in any kitchen – running every time cooking happens, managing heat, steam, grease, and odours through every meal. Despite this, it is frequently chosen with less research than a new smartphone. Understanding what actually matters in a cooker hood – beyond the aesthetics that dominate most purchase decisions – produces a choice that serves the kitchen well for years rather than one that disappoints in regular use.

The Ducted vs Ductless Decision

The most consequential decision in choosing a cooker hood is whether to install a ducted or ductless system. Ducted extraction channels air outside the building and delivers consistently superior performance – particularly for odour management and combustion gas removal. Ductless extraction filters and recirculates air, avoiding the structural requirement for external ducting. Where ducting is feasible, it is the better choice. Where it is not, a quality ductless system with proper filter maintenance performs adequately for most domestic cooking.

Extraction Rate Matching

The extraction rate – the volume of air the fan moves per hour – must be appropriate for the cooking surface below and the typical intensity of use. Underpowered extraction allows cooking vapours to accumulate; overpowered extraction creates unnecessary noise. The standard guidelines – 100 CFM per 10,000 BTU for gas, approximately 100 CFM per linear foot of range for electric – provide starting points that should be adjusted upward for kitchens where high-intensity cooking is frequent.

Filter Maintenance Reality

Every cooker hood requires filter maintenance. Grease filters need regular cleaning – monthly for most households – to maintain airflow and prevent fire risk from grease accumulation. Carbon filters in ductless systems need periodic replacement to maintain odour control. Brands like Ciarra One provide clear maintenance guidance and design their filter systems for accessible cleaning and replacement, making the ongoing maintenance realistic rather than an obstacle to proper system care.

Investment vs Running Cost

A higher initial investment in a quality cooker hood typically produces lower running costs through better energy efficiency, longer motor life, and more reliable performance. Cheap hoods with inadequate motors often run at maximum speed to achieve adequate extraction – creating more noise and consuming more energy than a properly specified unit that can achieve the same extraction at medium speed. Choosing a hood whose motor specification comfortably covers the actual extraction requirement produces better outcomes across both initial and ongoing cost categories.
