How Does The Bathroom Hood Work, And How To Choose The Best One?


Some bathrooms, even if they have small windows, do not have enough ventilation. This is a big problem because the lack of air circulation can cause mold to appear in your home, in addition to the difficulty of dispersing the unpleasant odor after use. To solve this situation, it is necessary to use a bathroom hood. Click here for more information and learn more about this apparatus using this post:

How Does The Exhaust Fan Work?

The bathroom hood works using a small propeller, capturing the air inside and sending it out through a duct. This process also removes excess moisture. It is a relatively simple mechanism, which works connected to the electrical network.

The hood doesn’t need to be on all the time, as, for most models, this would be an unnecessary waste of energy, in addition to the device making a particular noise.

Generally, in the installation, a presence sensor is placed so that the hood only activates when the bathroom is used. Another option is to install a switch so that the exhaust turns on when desired.

What Is Care?

When installing, it is necessary to observe where the hood will be placed; if it is on a recessed plaster ceiling, it is necessary to use a flexible and corrugated aluminum tube. For walls, it is good to install a protective screen on the outside to prevent insects from entering the house through the system.

To clean, care is quite simple: use a vacuum cleaner or a damp cloth with mild soap. When you notice that the dirt is not coming out entirely with these measurements, see a technician who disassemble the apparatus for a more thorough cleaning.

How To Choose The Hood?

First, you need to define whether it will be on the wall or the ceiling. If all the bathroom walls face inside the house (which usually occurs in suites), it is best to opt for the ceiling.

Second, you need to consider the size of your bathroom to avoid choosing an inefficient model. The airflow, measured in cubic meters per hour, must be compatible with the dimensions of the bathroom in square meters.

In general, what differentiates each model of the exhaust is the diameter of the air passage. For small bathrooms, up to 7m², the diameter can be 100mm. For medium-sized bathrooms, from 7m² to 15m², choose 125mm. For large bathrooms, a diameter of 150mm is ideal.

What Do I Need To Know Before Installing?

You need to keep two things in mind before buying a bathroom hood. The first is that if it doesn’t stay on permanently, your electricity bill is minimal, representing a negligible increase in your bill.

The second is that, despite the installation being a simple procedure, it is always necessary to have the help of a specialized professional in case of repair services, at least when breaking parts of the wall or ceiling; if this is done wrongly, it can have severe consequences for the structure of the house.
