What do ventilation fans do

It helps circulate air through the building or home, which prevents individuals from breathing stuffy, less oxygenated air. Without ventilation, you and other individuals will be left breathing air that is not fresh. When pollutants and contaminants enter the air, exhaust fans remove them in order to provide clean air. Some common contaminants and pollutants include smoke, moisture, dust, and odors.

Smoke from cooking and moisture from a hot shower can efficiently be removed from the air by this type of intake fan. If these contaminants are not removed from the air, you will subject your lungs to possibly breathing in harmful particles. Both ventilation fans and exhaust fans work to create the freshest, cleanest air possible in the space they are installed. The main difference between the two types of fans is their application. While a ventilation fan works to bring clean air into an enclosed space from an outside source, an exhaust fan removes pollutants from the indoor air in a home or commercial space.

Fan and heater can operate together or independently offering you ventilation and warmth if needed. In order to get the most out of your bathroom fan, it is important to install one that will provide all of the necessary functions. Although there are many reasons for using bathroom exhaust fans, many people often fail to do so. In most cases, this is because the fan is loud and annoying.

This is a common problem which occurs when the fan is not properly installed. Poor installation also frequently involves a lack of insulation, which can cause heat to escape into the attic. Fortunately, all of this can be avoided with the appropriate exhaust fan and the proper installation. The key to ventilation and installation is to guarantee the air gets brought outside. Older homes that have it vented into the attic can experience mold from moisture collecting.

And some will use the formula discussed in Chapter 2; Length x Width x Height x. There are many steps and options to complete this section. Lowes lays out step-by-step instructions with images on your mounting options. Decide which suits your current situation. Bathroom exhaust fans are a crucial element that should not be overlooked in your home. It is important that you install an exhaust fan of high quality, that way you can rest assured knowing you made a smart investment.

One of the certified products they suggest is the Greenheck SPVG as one of the premium plus bath fans. According to Energy Star, "This fan utilizes an EC motor that is extremely energy efficient and allows the installer to balance the fan to precisely meet the ventilation demands of a given space.

It also includes lighting, three speeds, and 0. Installing acceptable ventilation will help control moisture and remove foul odors. Simple Toilet gathered the best exhausting fans for If you see dust on the fan, you are long overdue.

If you notice more steam than usual on the mirror, you are long overdue. Hold a piece of toilet paper up to the fan. If it's getting sucked up by the fan, it's still working. Having a clean and functional fan in your bathroom is just as important as any other cleaning job in your home.

Stop putting the task off. Step 1: Turn the fan off at the circuit breaker or switch. No electricity allowed. Step 2: Remove the cover. Pull the fan cover down gently. You may see just a tab depending on the model. Step 3: Wash the fan cover in a sink with soap and warm water.

Or vacuum to clean the vent cover. Step 5: Depending on the model of your fan, remove visible screws and motor. Step 6: Clean the fan blades and surrounding motor parts with a damp cloth. If you are not comfortable taking the motor out, you can just vacuum inside the fan housing and around the motor.

Step 7: Clean the exhaust vent and surrounding area. Let everything dry out before replacing your vent cover. Our friends at One Good Thing , give you a step by step with images and all. Your home consists of heating and air conditioning systems that are essential to the comfort and well-being of your home and goes well beyond your bathroom.

Some designs use a single-point exhaust. Because they directly supply outside air, balanced systems allow the use of filters to remove dust and pollen from outside air before introducing it into the house. Balanced ventilation systems are appropriate for all climates.

Because they require two duct and fan systems, however, balanced ventilation systems are usually more expensive to install and operate than supply or exhaust systems. Like both supply and exhaust systems, balanced ventilation systems do not temper or remove moisture from the make-up air before it enters the house. Therefore, they may contribute to higher heating and cooling costs, unlike energy recovery ventilation systems. Also, like supply ventilation systems, outdoor air may need to be mixed with indoor air before delivery to avoid cold air drafts in the winter.

Energy recovery ventilation systems provide a controlled way of ventilating a home while minimizing energy loss. They reduce the costs of heating ventilated air in the winter by transferring heat from the warm inside exhaust air to the fresh but cold outside supply air. In the summer, the inside air cools the warmer supply air to reduce cooling costs. There are two types of energy-recovery systems: heat-recovery ventilators HRV and energy-recovery or enthalpy-recovery ventilators ERV. Both types include a heat exchanger, one or more fans to push air through the machine, and controls.

There are some small wall- or window-mounted models, but the majority are central, whole-house ventilation systems with their own duct system or shared ductwork. The main difference between a heat-recovery and an energy-recovery ventilator is the way the heat exchanger works. With an energy-recovery ventilator, the heat exchanger transfers a certain amount of water vapor along with heat energy, while a heat-recovery ventilator only transfers heat. Because an energy-recovery ventilator transfers some of the moisture from the exhaust air to the usually less humid incoming winter air, the humidity of the house air stays more constant.

This also keeps the heat exchanger core warmer, minimizing problems with freezing. In the summer, an energy-recovery ventilator may help to control humidity in the house by transferring some of the water vapor in the incoming air to the theoretically drier air that's leaving the house.

If you use an air conditioner, an energy-recovery ventilator generally offers better humidity control than a heat-recovery system. However, there's some controversy about using ventilation systems at all during humid, but not overly hot, summer weather. Some experts suggest that it is better to turn the system off in very humid weather to keep indoor humidity levels low. You can also set up the system so that it only runs when the air conditioning system is running, or use pre-cooling coils.

However, they are most cost-effective in climates with extreme winters or summers, and where fuel costs are high. In mild climates, the cost of the additional electricity consumed by the system fans may exceed the energy savings from not having to condition the supply air. Energy recovery ventilation systems usually cost more to install than other ventilation systems.

In general, simplicity is key to a cost-effective installation. To save on installation costs, many systems share existing ductwork. Complex systems are not only more expensive to install, but they are generally more maintenance intensive and often consume more electric power.
