How to Test an Extractor Fan and Ensure It's Working Properly
Learn how to test an extractor fan step by step, from checking power and airflow to spotting motor issues, so you can fix problems before calling a pro.

Also known as fan performance check, it helps ensure safe and effective ventilation. An extractor fan, the device that pulls smoke, steam and odors out of your cooking area works together with kitchen ventilation, the overall system of ducts and vents that maintain indoor air quality. The test tells you whether the fan is moving enough air to meet local building standards and keep your cooking space comfortable. In short, an extractor fan test assesses airflow efficiency, helps you spot blockages, and tells you if the fan motor needs attention.
Good ventilation isn’t just about getting rid of smells – it protects your health, reduces moisture damage, and keeps fire risk low. When the fan’s airflow drops below the recommended 15 m³/min for a typical kitchen, you’ll notice lingering steam, longer cooking times, and a musty smell. That’s a clear sign the test has uncovered a performance issue. The test also uncovers electrical safety concerns; a weak motor can overheat, and loose wiring can spark. By measuring the static pressure across the fan, you can calculate whether the motor is working within its design limits. If the pressure is too high, the fan blades may be clogged or the ductwork could be undersized. Cleaning the filter is often the quickest fix, but if the airflow still falls short, you may need to replace the motor or upgrade the fan size.
Maintenance plays a big role in keeping numbers up. A dirty filter can cut airflow by up to 30 percent, so regular filter maintenance is essential. Swapping out a metal mesh filter for a carbon‑coated version can improve odor removal while still allowing good flow. Many homeowners also ignore the duct’s inner surface – a buildup of grease can act like a second filter and cripple performance. A quick visual inspection, followed by a flexible brush clean, usually restores most of the lost capacity. When you combine these simple steps with a proper extractor fan test, you’ll see measurable improvements in air quality and energy use.
For DIY‑savvy folks, the test is doable with a handheld anemometer or a simple pressure gauge. You’ll need to turn the fan on, measure the air speed at the grille, and convert that to cubic metres per minute. The process requires basic electrical safety knowledge: always shut off the breaker before removing the fan cover, and double‑check that the wiring is secure. If you’re uncomfortable handling live wires, that’s when an electrician steps in – they can verify that the fan’s power rating matches your home’s circuit and that grounding is correct. Safety first, because a mis‑wired fan can not only fail the test but also become a fire hazard.
