A bathroom vent fan is an essential ventilation device that exhausts indoor air to the outside through the metal duct or flexible tube.
Most importantly, this kind of fan in your bathroom will boost eliminate moisture-related problems, stale odours and the growth of mould and mildew at the same time improves the air quality as well.
Installing a vent fan in a bathroom is not a good idea, but now many building codes need it for modern construction. The building code contains earmarked recommendations for coming true the size and shape of the fan which is measured by CFM, to the square footage of the room.
This building code requirement is not applicable to all communities. Just check your area. For instance, the bathrooms that have windows were no required to have this fan, but a vent fan is better for any bathroom.
Some people think that a bathroom vent fan helps to remove odours primarily from a bathroom, but more significant action is basically to alleviate warm or moist air which produced the use of shower or bathtub.
This warm and moist air stimulates mould growth at the same time can damage the surfaces and fixtures in your bathroom. Howsoever, if in your bathroom there is no fan and always stays ill-smelling, then you have to install a vent fan.
Except for vent fan in a bathroom, there is possible to build up excessive moisture that raises the chances of spoiling floors, ceilings and walls, as well as a fixture. In the time of running hot water for shower and baths, warm, humid air are created and that is also a suitable environment for the growth of mould and mildew.
Excess moisture in bathrooms can damage such materials-wall paint, wallboard and trim. So, to get a safe and hygienic bathroom you need proper ventilation.
Vent Fans Operating System
A vent fan requires a household electrical current (standard 120-volt). It may be wired to the ceiling electrical circuit which powers a light fixture.
A wall switch conducts the vent fan that may have a timer option and it will approve the fan to continue operating for the right time. If you turn on the fan, the air is shifted through the fan enclosure or into a metal duct or a plastic hose from your bathroom.
Bathroom vent fans differ in styles, sizes and colours, however, there are more sophisticated models that organize a speaker and Bluetooth capability, offering fully wirelessly from a tablet, smartphone or home media player to stream music.
When purchase vent fans just pay attention to the sound ratings. Although it is not a major point, while you attempting to relax by soaking in your bathroom, sound creating fan can be thoroughly distracting your enjoyment.
The appropriate choice for sound ratings is 1.0 or less. So, you must remind it-if the sound rating is lower, the fan always quieter.
The other important choice of the fan is a sufficient capacity for the size of your room. To measure the vent fan capacity, CFM is the perfect medium. Generally, the high capacity is better, but if the vent fan unit is so powerful for your space, it can make a negative situation in your bathroom.
So, when choosing a vent fan it is really serious to check the unit size properly for the square footage of a bathroom.
- 50 CFM means less than 50 square feet
- 1 CFM per square foot means more than 50 square feet
Certification of HVI
To meet particular industry standards HVI (Home Ventilation Institute) provides certification for vent fans.
If you choose the appropriate size and install it properly, HVI certified fans are extremely guaranteed to run as promised.
It is superior to set the vent fan close to the most moisture like near the shower or over your sink. For an open bath place, you can install the vent fan in the middle point of the shower and toilet area. If it is a small bathroom, centring is the best idea.
You notice that the outer vent louvre runs properly where it closes completely while your fan is not in use. It will also maintain cold air when your vent fan is not operating.
Put apart around the metal duct or flexible nose which leads from your fan housing to the outside louvred cap. It will assist in minimizing the less of inside heat to the outsides.
You should not tightly seal the void beneath your bathroom door. Keep a ¾ inch gap for exhausting air by the fan.
For extra-high ceilings of a bathroom may require a vent fan by extra capacity.
