Introduction

Bathrooms are one of the most commonly used spaces in any home but share a common issue: moisture and lack of ventilation. Without proper airflow bathrooms will accumulate more mold, mildew, damp walls and odors. This is when a bathroom ventilation fan comes into play.

Selecting the proper fan may seem easy, but with so many models, sizes, and features to select from, it can become overwhelming to know which fan is for you. This is where this guide will step in, and walk you through what you need to consider with a bathroom fan, including the type of fan, and how to install the fan.

 Why Are Bathroom Ventilation Fans Important

1. Moisture Control - Prevents damage walls, peeling paint, and water damage

2. Air Quality - Eliminates smells and keeps the bathroom smelling clean

3. Health Benefits - Limits diseases and allergies due to mold and mildew

4. Increases Fixture Lifespan in Bathroom - Airflow prevents tiles, mirrors and cabinets from drying out from humidity

5. Comfort - Enjoy a dry and breathable space after multiple showers

Different Types of Bathroom Ventilation Fans

1. Ceiling Fans

• Are installed in the ceiling
• Pulled air up and away through ductwork outside
• Best used in small to mid-sized bathrooms

2. Wall Fans

• Attached directly to the wall
• Push air outside through the wall opening
• Best used in bathrooms without any ability to use the attic or ceiling ductwork

3. Inline Ventilation Fans

• Installed inside the duct (away from the bathroom)
• Have a quieter operation because the fan motor is outside the bathroom
• Best used in large bathrooms, or if there are multiple points to ventilate from, as well as maximizing airflow

4. Exhaust Fan/Light/Heater Combo

• Various multi-functional models, each with different light or heating options
• Will be more convenient and comfortable depending on your application (especially in cooler climates)

Important Considerations Before Purchasing:

1. Fan Size & Air Movement / Air Flow Capacity (CFM)

• CFM stands for cubic feet per minute.
• Small Bathrooms (<50 Square Feet): 50 CFM
• Medium Bathrooms (50-100 square feet): 80–100 CFM
• Large Bathrooms (>100 square feet): Either use multiple fans or higher capacity fan options that can handle additional air movement.

2. Noise Level (Sones Rating).

• Noise level, or decibel reading is rated in sones which are a unit of sound.
• Quiet Fans (1.0 sones or below).
• Moderate Noise (1.5 – 2.0 sones).
• Loud Fans (3.0 or higher).
• Consider the type of atmosphere you want in a bathroom, if you prefer total quiet operation, select a fan with a low sones number or rating.

3. Efficiency

• Look for fans that have an Energy Star certification which means they are efficient and can save you money on electric bills.
• Efficient bath fans will be more durable, last longer and reduce your carbon footprint.

4. Additional Features:

• Humidity sensor: fan will automatically turn on with moisture levels rising.
• Motion Sensor: fan will automatically activate if someone enters the bathroom.
• Timer: Automatically shut off an hour after turning on.
• LED Lighting: light and ventilation all in one fixture.

5. Design and Aesthetics:

• Many modern fan options are being built to resemble or match the interior design with sleek and clean designs.
• Decide on the type of grille or any other color / design you want to present in your bathroom.

6. Installation Requirements:

• Ensure your existing bathroom has access to an attic or ducts.
• Choose a wall mount fixture if there is no ceiling space in your bathroom.

Bathroom Ventilation Fan Installation Tips

1. Correct Placement – Installed it above or near the shower/tub. Most moisture will occur here.
2. Ducting – Make sure ducts go outside and not to the attic (you don’t want mold up there to ruin the insulation!).
3. Look at the electrical wire. Call in a professional if you don’t feel comfortable.
4. Cleaning – Your fan grill and ducting should be cleaned at least twice a year.
