Kitchen extractor fans must be replaced every 7-10 years due to wear and tear. Choosing the right extractor can enhance kitchen aesthetics and air quality. Experts suggest selecting a model that fulfills at least 15 air changes per hour based on kitchen volume for optimal performance. It's important to also consider filter maintenance and energy efficiency. Proper installation requires careful calculation of air volume and consideration of existing kitchen ducting and electrics to ensure functionality and compliance with regulations.
It is advisable to follow building regulation part f guidelines and install an extractor which meets these minimum levels, but above all I would suggest choosing an extractor that can provide you with at least 15 air changes an hour when extracting externally.
To calculate this, you need to work out the volume of air in your kitchen. For example, a 3m by 3m kitchen with a ceiling height of 2.4m would be calculated as 3 x 3 x 2.4 = 21.6m3 of air volume.
