Home Ventilation Made Simple: Fresh Air for Every Room

Ever walked into a kitchen that feels hot and stuffy after cooking? Or a bathroom that smells like a damp cave? Good ventilation fixes both problems and saves energy. Below are quick steps you can take right now, no need for a full remodel.

Pick the Right Fan for the Job

Fans are the workhorses of ventilation. In the kitchen, an extractor fan above the stove pulls out steam, smoke, and cooking smells. Look for a model that moves at least 300 cubic feet per minute (CFM) for a standard hob. If you have a larger cooktop, add 100 CFM for each extra burner.

Bathroom fans work a bit differently. They need to handle humidity to stop mould. A fan rated at 1 CFM per square foot of floor space is a good rule of thumb. For a 70‑square‑foot bathroom, aim for 70 CFM minimum. Make sure the fan exhausts to the outside, not just into the attic.

DIY Boosts for Better Airflow

Can’t afford a new fan? Try these low‑cost tricks. First, keep vent grilles clean – dust and grease cut airflow by up to 30%. A quick vacuum or a damp cloth does the job.

Second, create a cross‑draft by opening a window on the opposite side of the house when you’re cooking or showering. Even a small window open a few inches can double the amount of fresh air coming in.

Third, install a simple vent hood extension if your current extractor sits too low. Adding a few extra inches of duct length directs air straight out and reduces back‑pressure.

Lastly, check the fan’s wiring. A loose connection can make the motor run slower, cutting its efficiency. If you’re comfortable with a screwdriver, turn off the power, unscrew the fan cover, and tighten any loose screws on the motor.

Good ventilation isn’t just about comfort – it protects your home’s structure. Proper airflow stops moisture from seeping into walls, ceilings, and cabinets, which can cause rot and costly repairs.

So, whether you’re swapping out an old extractor or just cleaning the filters, a few minutes of work can make your kitchen and bathroom feel brand new. Keep the air moving and you’ll notice the difference the next time you cook a big meal or take a hot shower.
