Exhaust fans and what do they do for your home?

Bath fans are essential for any home, and they are mainly used in bathrooms. These devices keep the bathroom air clean and dry by exhausting it out. The air in bathrooms is typically moist and can cause damage to the exterior wall, bathroom ceiling, and other surfaces in the home if it is not removed. 

Bathroom vent fans help protect your home from this type of damage by removing the moist air and bathroom odors.

There is a variety of bathroom ventilation on the market, and each one serves a different purpose. A powerful fan removes humid air, allows air movement protecting the bathroom wall from moisture damage, while others remove smoke and odors. It is essential to choose proper bathroom ventilation for your home.

Bathroom Exhaust Fan Options

Bathroom exhaust fan options are a hot topic in the bathroom industry. It’s not surprising that exhaust fans seem to be everywhere these days, but there are many different types of exhaust fans to choose from.

The exhaust fan you choose for your bathroom will depend on a few factors, including the size of your bathroom, the type of ventilation you need, and your budget. Here are five popular exhaust fan options to consider:

1. Window Fan

Window exhaust fans are one of the most common types of bathroom fans. They’re easy to install, they’re affordable, and they can exhaust a lot of air in a short time.

The downside to window exhaust fans is that they have very low airflow capacity. Window exhaust fans are best for small bathrooms with limited ventilation needs.

2. Ceiling Fan

Ceiling exhaust fans are the most popular type of exhaust fan, and they’re perfect for small bathrooms. They install easily in the ceiling, they have high airflow capacity, and they’re relatively affordable.

However, ceiling exhaust fans can be disruptive when they startup, and they are also vulnerable to rain. Another downside is that the exhaust fan is exposed to animal intrusion, especially bird nests.

When installing a ceiling exhaust fan, make sure to seal the vent hood with caulking and keep the vent cover intact.

3. Ductless Fan

Ductless exhaust fans are a great option for bathrooms that don’t have access to ductwork. The downside to ductless exhaust fans is that they exhaust air directly into your bathroom.

This can cause humidity to build up in your bathroom and make it a breeding ground for mold growth and mildew.

Ductless exhaust fans are best for bathrooms with limited ventilation, like guest bathrooms or powder rooms.

4. Wall Fan

Wall exhaust fans are great for bathrooms with limited space. They are easy to install and have high airflow capacity. There are also two options of wall exhaust fans:

Through-the-wall fan

This type of fan is usually installed in exterior walls, so the air exhausts instantly through the wall and outside. This means that the vent is only a foot or perhaps two without any bends and turns. The exhaust fan pulls the air out through the wall and pushes it outside.

Low Profile Fan

You install low-profile exhaust fans in interior walls so they don't have an exposed vent as the through-the-wall exhaust fans do. Low-profile exhaust fans also have a grill that you can paint to match your bathroom walls.

The exhaust fan pulls the air out through a vent in the wall and doesn’t go directly outside — instead, it exhausts into your attic.

5. Roof Fan

A roof vent is excellent for larger bathrooms that need more ventilation capacity than ceiling exhaust fans can provide.

The exhaust air goes directly into the attic, which cuts down on unwanted noise in your bathroom. The downside of roof exhaust fans is that they can develop attic condensation. 

The air difference between the attic(hot) and the bathroom creates a water bead on the outside or inside of the vent, causing moisture and eventually mold in the attic.
