If you need to get rid of the humidity and odors that occur in the bathroom and you do not have a window that you can open, the solution we offer is very simple, you need to buy a bathroom extractor, and if it is silent then much better.
Do not hurry if you do not know where to start, in this guide you can see all the necessary information to buy the right ventilation products easily and quickly.
Keys to buy a bathroom extractor
Extraction flow
The flow specifies the amount of cubic meters of air that the fan can manage, that is, the volume that can be exchanged per minute during the operation of the product.
To calculate the flow you need, you only have to multiply by 10 the volume of the stay (Width x Length x Height). For example for a bathroom with these dimensions: 3 meters wide x 1.5 Long x 2.5 High, you need:
Volume (m3): 3 x 1.5 x 2.5 = 11.25 cubic meters.
Flow rate of the extractor to be purchased: 10 x 11.25 = 112.5 m3 / hour
For most situations, just one extractor is sufficient, but if the bathroom is particularly large, you may have to consider using two fans to effectively remove all moisture.
Power and noise
A fan is composed of a motor and a plastic casing that protects it, so keep this in mind when you go to buy this device that generates noise.
The power of domestic extractors ranges from 8 to 35 watts (depending on the size and flow absorbed), so keep in mind that by default, the higher this value the more noise is produced.
Anyway nowadays you do not have to worry too much, there are silent and powerful bathroom extractors with which you will only hear a quiet buzz that barely bothers you.
Ways to operate the fan
There are several ways to operate the bath extractors, so this decision must be made before the purchase. Let's see what they are.
Manual : it is the most common in homes, by means of a switch the air extractor is started.
There are cases where the light switch connects to the extractor, but we do not recommend it since every time you enter the bathroom and turn on the light, you will have to endure the noise from the fan motor, no matter how quiet, so the perfect solution is to be independent and press it whenever you want.
Presence detector : works with a sensor that when it detects presence starts the bath extractor. You are in the same case as in the previous one, it always turns on.
Timer : the standard time required to remove the moisture stays on and then automatically turn off.
Hygrostat : they work with a sensor that captures the humidity of the environment and is activated or turned off automatically. It is the perfect solution since you do not have to be aware, although the price is a bit more expensive.
Colors and finishes
The color and finish of the bathroom extractor can be an important factor for many people because, like any other product, it affects the decoration.
Most fans that are sold are usually plastic and white or gray, however you can also find them with glass, chrome or stainless steel, yes, the price is not so cheap.
How to install an extractor
Although the installation is simple for you to do it yourself, if you do not have basic notions of electricity or it gives you respect, do not even try it, hire a professional and leave yourself in trouble.
However if you are a handyman in the following video you can see step by step how to do the installation of these products, but keep in mind the regulations and these tips:
You can not install extractors on the bath or shower, unless you place it at a distance greater than 2.25 m in height. This is not the most common since there are usually about 2.50m from floor to ceiling.
The extractor can be installed on the ceiling or wall. If you go directly to the outlet pipe of the house, measure its diameter to buy the right product.
Do not install the ventilation above the radiator as the heat will be lost through the conduit.
You must carry the electricity cables where the extractor is installed. Except that during the renovation work of the bathroom they have done it, or you have a false ceiling or you will not be able to place it unless you want to do another work.
Why do you need air extractors?
Most of the bathrooms in a house have a ventilation fan, it is a sensible idea since it is the most humid room in the house.
If still doubts we are going to give you two good reasons to install a bathroom extractor:
Prevents mold and moisture
Each time you shower or bathe a large amount of moisture is released into the air in the form of vapor, which cools and condenses on ceilings and walls. This causes that, as the days go by, a big problem, mold, is gradually generated.
Mold is not only unsightly, it can also be dangerous to your health. As the environment heats up again, the contaminated particles are distributed through the air you breathe, contributing to all kinds of respiratory problems and even asthma.
Installing a bathroom fan is the solution to this problem.
The mirrors are designed
Who does not have a bathroom mirror? the warm, moist air that occurs when the shower is used can cause it to fog. Although it is a smaller problem than the previous one, it will force you to pass your hand or towel in case you want to see yourself combing or shaving.
This is uncomfortable and stains the mirror. An air extractor for bath will eliminate moisture by ventilation, preventing and eliminating this situation.
