!±8± Different Types of Exhaust Fans

Temperature is elevating and you want to cool down but will you risk electric costs by using an expensive air conditioner? The list provided below is different types of exhaust fan you can use as an alternative way to make your house more comfy without the odds of soaring electric bills. There are various exhaust fans which are mostly determined by the location where it will be mounted. Types of exhaust fans include:

Wall Fans: A type of fan settled on the wall of the house. They are mounted on the exterior wall and not on the interior of the house. Using this will provide your home a direct rotation of air so there is no need to install ducts.

Ceiling Fans: These are the ones mounted on the ceiling of your home. The motion of the air is upwards, thus expelling it through your roof. A duct is connected to the fan which is situated outside the house through external ventilation.

Kitchen Fans: Fans that are installed above your kitchen stove. Most modern stove set already includes exhaust fan. It is not only for expelling air but also for repelling foul smell from the food you are cooking and decrease the moisture content in the area.

Inline Mounted Fans: These are installed in between ducts. Mostly used for houses with small area like single units especially when there is no space to mount the device.

Exterior Mounted Fans: As the name suggests, these are the ones installed outside your homes which pulls air outwards rather than pushing it. These are some of the common types of fans you can avail to ensure proper ventilation in your house.

Fan Calculations - Measure Airflow with CFM

!±8± Fan Calculations - Measure Airflow with CFM

With one formula, you can find what fan is right for your home. This is the formula for fan CFM: Cubic feet per minute, more commonly known as CFM is calculated by the following formula: air speed (feet per minute) X area (square feet)=CFM. Not everyone is going to take a look at CFM, but for those who do it is a helpful tool. In simpler words than that of the formula, it is the amount of air a fan moves.

The amount of air depends on some other factors as well, such as the diameter and shape of the blades, speed at which the blades turn (revolutions per minute or rpm), horsepower (hp) of the motor, and overall fan design. These combined factors establish the air moving capacity of a fan. Fan capacity is measured in terms of the cubic feet, and again, this is how CFM (cubic feet per minute is determined.)

CFM and RPM are the two most important things to look for in a fan, so that you are guaranteed correct and effective operation. If you only know the RPM, and not the CFM, or vice versa, you should feel confident in your fan purchase. As long as you know one of the calculations, you are ensured of a well-working fan. However, if you are not satisfied with these calculations, this is not the only criteria one can use for evaluating fan performance.

One of the main qualifications, second to rpm and CFM measurement is noise level or decibel rating, followed by the next qualification of vibration. Look for fan noise levels rated in sones or decibels. Check these if the CFM or RPM still leave you unsettled about your fan choice.

A standard measurement of airflow indicates how many cubic feet of air passes by a stationary point in one minute. The higher the number, the more air is being forced through the system. The volumetric flow rate of a liquid or gas in cubic feet per minute equals the CFM, and one CFM equals approximately 2 liters per second.

Fan manufacturers base their measurements on a standard measurement with clean, dry air at a density of 0.075 pounds mass per cubic foot, barometric pressure at sea level of 29.92 inches of mercury, and a temperature of 70°F. These standard measurements are used to determine SCFM: Standard Cubic Feet Per Minute.

With the use of CFM and RPM, you can make a more educated choice when choosing your home ceiling, exhaust, or table fan, and know what you are getting!

Indoor Mold - 8 Ways to Eliminate Indoor Mold

!±8± Indoor Mold - 8 Ways to Eliminate Indoor Mold

Indoor mold is the indicator that you have an excess water or moisture problem in your home. Moisture/water can come from many sources like a leak in piping or seeping in through your basement floors. Even just taking a shower or boiling a kettle adds moisture to the air in your home.

Colder environments can hold less moisture than warmer environments. That is why moisture is seen to condense on the inside of windows for example, when the weather outside gets colder. And when this moisture collects, it becomes a perfect medium for mold growth.

So is there something you can do to try to control indoor mold in your home? Yes there is! Control the moisture in your home. Below are 8 ways in which you can do just that!
Fix any leaks or seepage that you witness in your home. Cover the dirt in your crawlspaces with plastic and ensure that they are well ventilated. Install and use kitchen and bathroom exhaust fans to expel moisture outside. Ensure that the laundry dryer is vented to the outside. Turn off humidifiers or kerosene heaters when you experience moisture condensating on windows or anywhere else. Install dehumidifiers and/or air conditioners for use in warmer and more humid environments. Increase the temperature of cold surfaces where moisture condenses. Increase circulation to rooms where moisture is higher by use of fans and opening doors.

It doesn't matter where you live, most areas have some sort of moisture problem. Some are produced by the environment as in the north where the temperature varies greatly from summer to winter. Others are created by man in our effort to cool our environment in order to be comfortable.

For the sake of your health and the health of those living in or visiting your home, control the moisture within your home to help eliminate indoor mold.
