Do I need a fan in the bathroom

The notion that a fan for the bathroom manufacturers have come up to cash in on consumers does not correspond to reality. After all, the living conditions in the different houses are radically different. A working ventilation system does not always meet the needs.

Request for tenants of the house / apartment are different - someone washes clothes in the bathroom, loves to bathe for 1-1.5 hours, and someone only takes a 5-minute douche.

Fan for the bathroom: how to choose

If you want to buy a fan, the inexperienced owner of the house / apartment can easily get lost among a variety of devices. They all differ visually and their cost. The biggest mistake - select equipment based on the price, which seems the most appropriate.

What are the ventilation devices

Question fans need is always solved individually. If you need a device that will choose an optimal model, capable of performing its function of removing exhaust air from the bathroom / shower.

Fans differ in appearance
All fans differ in appearance, the method of attachment to the principle of action and location

  • overhead mounted at the entrance to ventkanal;
  • duct placed inside the duct.

These devices are not only appearance, but also their capabilities. Depending on the skill of the fan is significantly different price. The range presented fans of European and domestic manufacturers - SILENT Spanish, Italian Elicent, Bulgarian Mmotors JSC, Russia's "Era", Ukrainian Vents.

SILENT Models Bathroom

Among the possibilities for bathroom fans are the most popular models, with temperature and humidity sensor, a timer, a separate power button, protective curtains and a check valve. Another find - more decorative panel that allows you to create a unique look of the device, emphasizing the exquisite design of the room.

Rules of selection of the fan to the bathroom

To the unit to cope with their responsibilities to remove exhaust air and delight its users, it is necessary to choose the right model. To do this, it is important to take into account the important parameters of the fan of the future, which have a decisive influence on the choice of the final version.

Firstly, you need to choose the desired power of the fan based on the volume of bath / shower rooms and a diameter of the hole, which will be placed fan. This 100, 125 mm, and others.

To determine the power can use the regulations, according to which the premises of this type should provide air renewal at 3-8 times per hour.

In practice it turns out that the need room to length * width * height * on the ceiling at the multiplicity (from 3 to 8). To this number must be added 20% - this is a small margin that provides free operation of the device.

The exhaust fan in the bathroom
If the fan will work constantly on edge, full power, its service life is significantly reduced. It is better to provide a small supply of power to purchase in the amount of 15-20%

The second selection criterion - safety equipment. This is an important criterion, because it will be placed in a room with high humidity. And the random splashes can not be excluded.

Fan with protection from moisture
Therefore, it is important to choose a model that has the appropriate moisture protection class

Thirdly, the important role played by the fan noise in working condition. The most acceptable option - up to 35 dB. The lower the score, the more comfortable will feel all the members of the family enjoying a bath or shower with a mounted unit for ventilation.

If the fan noise of 40 decibels and above, it can disrupt restful sleep especially sensitive households and cause headaches with a long stay in a ventilated area.

The noise has a negative impact
The noise has a negative impact on health and the nervous system of an adult human. You need to check before buying the noise level indicated in the instructions

The fourth criterion - simplicity of installation and maintenance instructions. Well, if a suitable option can be set with your own hands, without causing experienced craftsmen. And the ease of maintenance is important - the simpler and less, the more preferable.

Fifthly, we still have before buying to determine what features should be in the device - timer, decorative lighting, protective curtains, humidity sensor, the ability to control by SMS and more.

Fan for bath and shower
Bathroom and shower often take the model and very simple or with a mass of extra bells and whistles, so as not to feel discomfort

The sixth criterion for optimum fan selection - its cost. It would be desirable to buy the best model, always stops its price. It is on this parameter determines the final consumer's choice - one stop on the Spanish SILENT, while others prefer a more affordable devices of domestic production.

Seventh indicator that affects the selection of the fan in the bathroom - its appearance. That hardware design is appreciated by many consumers, carefully designed the interior of your home. The device should organically fit or bring flavor to the established style decision of a particular room.

Controversial issues in the selection of equipment

When choosing a fan for the bathroom / shower can be seen a lot of controversy about the additional features of the device between the owners. So often you can hear absolutely opposite opinions about the need / uselessness of the check valve. It is needed that the air did not come back.

Reverse fan valve
The role of the non-return valve is difficult to overestimate. The only trouble - it should be periodically serve

For example, if the neighbors fried fish / potatoes, then the fan is switched off the valve closes and prevents the air with the aroma of dinner next door to get into the apartment. If the door to the bathroom is tight, you can refuse to buy a model with non-return valve.

It is very individual, because many masters, setting the door to the bathroom, take into account the regulatory requirements and leave a gap from the lower edge to the floor in the 1-2 cm.

Another unpleasant phenomenon - these valves become clogged and may adhere to the fan. They require cleaning and maintenance. Every 6 months, you need to get the fan and clean the brush-return valve petals.

Controversial issues are models with louvered / protective grilles. You can often hear the opinion that it is desirable to take without them. Blinds are needed to close the hole in one easy motion when needed. This is justified when used by people who love to warm up and prone to colds.

When a special need for such a function is not present, constantly closed grille entail the emergence of stale air in the room when the fresh does not fall and the hours worked hard to remove.

Another issue causing debate - the safety net. It is needed to prevent the ingress of ventkanala cockroaches, moths, and other unwanted guests.

On the other hand, the grid is electrified, the dust settles on it and accumulates web. So you need to clean it often - every week or two. Put a protective mesh or not - is entirely dependent on the specific conditions of the bathroom layout.

Protective mosquito net of the fan
If in a private home is not observed insects and air ducts on the outputs already foreseen lattice of such a network can be waived

Also a lot of disturbances can be heard on the decorative panel, completely covering the direct ingress of air to the fan. It really affects the performance of the equipment. This should be considered when selecting a model for your bathroom.

When enjoyed 2 versions, differing in capacity, noise and cost, you can hear the advice that you need to take more powerful. This is wrong - power must closely match the needs of the room in the air update.
