How to Choose a Ceiling Exhaust Fan for Your Bathroom
During the showering and bathing process, moisture and odors are released into the air.ceiling exhaust fan If not ventilated properly, they can lead to the growth of mold and mildew, which can affect indoor air quality, trigger asthma and allergies, rot furniture, and eat away at sheetrock and wall studs. Fortunately, exhaust fans are designed to remove excess humidity and odors from the air. They also help control condensation, which is the leading cause of water damage to homes and buildings.
Traditionally, bathroom exhaust fans were vented to the space between ceiling joists or into the attic.ceiling exhaust fan This was a common practice in the 1970s and '80s, but nowadays building codes typically specify that your fan should be vented directly to your home’s exterior through insulated ducting. This solution is more sensible and healthier, as it prevents moisture from entering attic or wall spaces and eliminates the risk of mold in drywall or wood.
There are a variety of fans that can be installed in your bathroom, including the standard fan, which is often mounted on the wall and includes a light fixture.ceiling exhaust fan Other options include a decorative fan/light that blends into the ceiling and looks like a normal domed or flat paneled light fixture, or recessed fans with a low profile that can be hidden within a drop down soffit.
Whichever type of fan you choose, it’s important to select one with the right extraction value, quietness and energy efficiency. The extraction value is the rate at which the fan pulls stale air out of the room, and it’s measured in CFM (cubic feet per minute). Higher CFM ratings mean more effective ventilation, but they can be noisier.
The quietness of a fan is also an important factor, and the most efficient models use very little energy (and thus cost less to run). They should also be rated for use in moist environments.
A final consideration is whether or not a venting system is needed. This depends on your roof style and how many stories your house is. If you have a tiled roof with sarking underneath it, there’s no need for ducting because natural ventilation is sufficient. However, if you live in a newer or renovated house with a metal roof or no attic space, a ducted ventilation fan is necessary to prevent condensation build-up inside the house.
Regardless of the type of ventilation fan you opt for, it’s vital to run it after every shower or bath. It will ensure that the bathroom is drained of excess moisture, odours and smoke, reducing the risk of mould and other damage to your home. And remember to change your filter regularly! If you don’t, the dust and dirt in your ductwork can contaminate the fresh air being pumped back into your home.
