What’s Behind Our Ratings?

With so many types and models on the market, it may be quite complicated to find exactly what you need. When making a purchase, there are a few factors you need to take into consideration. Therefore, in order to find out what the best fan has, keep on reading the following lines.

• Remote control

  If you are on the hunt for a special model, make sure you choose one that comes with remote control. The remote controls have revolutionized the way people do things. By using a remote control, you won’t have to wake up in the morning to change a setting. In simple terms, the remote control will add convenience and will ease your work.

• Speed settings

  One of the most important things to consider when making a purchase is the speed of the device. While some models have 3-speed settings, there are also models with 2-speed settings like the Holmes Dual Blade Twin HAWF2021. However, although it has 2-speed settings, it still is one of the best models available in the current market. The speed settings give you the power to control how much air you want to draw in or suck out.

• Number of blades

  It is very important to understand that a fan which comes with twin or triple blades is able to increase the rate of airflow in your house. While single blade models are not able to suck out and draw in air at the same time, the ones with twin or triple blades can easily do this task. They are able to draw in and suck the air out at the same time.

• Noise

  If the white noise bothers you, make sure you opt for a device that does not create noise while in operation. The normal level of a device should not exceed 60 dB.

• Extenders

  Whether you forgot the measures of your window or you don’t carry much about this aspect, get a fan with extenders. These types of fans are made to fit any window, no matter the measurements.

• Safety features

They are an energy-efficient and cost-efficient alternative to expensive air conditioning systems, not to mention they are much easier to operate and install. A quality model is capable of improving circulation and cool your home, helping you save on energy costs. But, before making a purchase there are a few things you need to know.

• Using the right fan

  If you are thinking about purchasing a cooling system, take into consideration a few aspects. First of all, make sure you can install a fan in your home. While some houses can get great benefits from these devices, others might get the opposite effects. However, if you have problems with the outside temperature in your area, you can definitely benefit from a fan.

• The fan’s size

  One of the most important things to consider when making a purchase is the fan’s size. Since they are fitted on the windows, it is very important to buy one that will fit best. These systems come in various different sizes, that finding the right model for your window will not be very complicated.
  However, the best way to find the right model for your home is by measuring your windows. This way, you will know exactly which fan will fit. As mentioned above, there are extenders which can help you secure the device in place if it is smaller than normal.

• How powerful does it need to be?

  According to several specialists, a window fan should be powerful enough to draw in cool air and suck out warm air. In order to know exactly how powerful a window can be, take a look at its CFM rating. Its cubic feet per minute will tell you how much air it can move. More than that, it is important to understand that the volume of air the device moves is strongly related to the size of the living space. It needs to be powerful enough to cool you down without bowling you over.

• Easy to use controls

  As you have probably noticed, the most advanced models are equipped with various convenience features, including remote controls, timers, and thermostats. Although they are nice and easy to use, make sure the other controls are also easy to reach and use.

Window Fan vs. Air Conditioner

Looking to purchase a device to cool your house but deciding between a window fan and a traditional air conditioner is an overwhelming task?

The debate of these two devices seems to have a long history. It is quite hard to decide what to choose. Although fans are equipped with impressive features and settings, most people have doubts about all these technological advances.
Hence, we have tried to find the advantages and disadvantages of each unit once again.

At first glance, air conditioners are similar to window fans. Most of them come in a medium-size, they are fairly light in weight and feature a sleek and compact design. However, they are more expensive. Although they lack certain important features, they cost more than a standard window fan. Besides the initial price, a fan is also less expensive to maintain. Air conditioners require regular maintenance which is extremely expensive as well. However, most types of air conditioners are lightweight and portables. This is a big plus as they can be moved from a room to another with ease. On the other hand, a window fan is more efficient at cooling your house. It operates by extracting the warm air from the room and bring in cool air from outside.

The air conditioners tend to have higher CFM that can range from 1000 to 2500 CFM. Both window fans and air conditioners do a great job of cooling down a large area. The major differences between them consist of the price range, installation and maintenance. Also, it should be mentioned the lack of advanced technology and features when we talk about air conditioners.
