Quick 30-Second Test to Check Your Bathroom Exhaust Fan

Hey HRM! Today, we’re sharing a simple and practical tip that will help you protect your bathroom from moisture-related damage.

Many homeowners are unaware that a poorly functioning bathroom exhaust fan can cause serious issues over time, including moisture buildup, mould growth, peeling paint, and long-term structural damage—particularly in Nova Scotia’s climate.

The good news? You can check whether your bathroom exhaust fan is working properly in just 30 seconds, with no tools required!

QUICK TEST TO CHECK YOUR BATHROOM EXHAUST FAN

What you’ll need:

• A small piece of toilet paper

Steps:

• Turn ON the bathroom exhaust fan.
• Tear off a small piece of toilet paper.
• Hold it up to the exhaust fan cover.

Results:

• If the toilet paper sticks to the fan, it is operating correctly. ✔️
• If it falls down, the fan may be weak, blocked, or in need of replacement. ❌

WHY THIS MATTERS

A weak or non-functioning exhaust fan allows moisture to remain trapped in your bathroom, which can lead to:

• Mould and mildew growth
• Persistent odours
• Peeling paint or damaged drywall
• Costly repairs or renovations over time

CHOOSING THE RIGHT EXHAUST FAN

You can find homeowner-friendly exhaust fans at your nearest Home Depot or on Amazon to suit most budgets. We generally recommend selecting a fan with slightly higher capacity than your previous unit to ensure proper ventilation.
