Best Window Fan Buying Guide
As with every purchase you make, there are a few things to keep in mind to make the best out of it. Here’s what we think you should be considering when buying a window fan:
The Use Of The Fan
Unlike air conditioning, a standard fan is not able to actually change the temperature of a room. It is simply used to cool you when the temperature is too high, by circulating air.
Unlike basic fans though, there are three main uses of window fans: cool down, get better air circulation, or get stale air and odors out.
While all of these fans offer you these features, some are more practical than others. To ensure that you are getting the best match for your needs, go for a unit that can easily switch functions. Inward and outward airflow should be adjustable with a switch without having to remove the unit as a whole.
The best window fan will not require dismantling to change to this mode.
While a higher power rating usually translates to more efficient cooling, it also means higher electricity bills. A simple calculation will help you determine the power you need to achieve the desired cooling effect without wasting electricity.
The power of a fan is measured in cubic feet per minute (SCFM).
Most window fans are sold with a standard SCFM classification that indicates the speed of their air circulation capacity in a given area. In order to measure the cubic feet of your room, measure the distance from the floor to the ceiling, then multiply that number by the square footage of the floor (width x length).
While taking measurements is a great idea, you could skip most of that by going for a window fan with an adjustable thermostat. This will automatically set itself to meet your cooling needs.
This feature promises the most energy savings as you fan will be toggled to switch off most of the time. It is also great as you do not have to constantly reconfigure your fan to meet your needs.
The Size Of The Space To Ventilate
In order for the effects of the fan to be felt, it must be selected according to the size of your space. If you have a modest apartment or a single room, you can probably settle for an entry-level model, and there is no point in raising your budget.
Conversely, if you live in a large house with a large living room or other large rooms, it will probably be necessary to equip yourself with intermediate or high-end models, which offer enough power for you to feel the fresh air everywhere.
Frequency And Context Of Use
If your fan runs every day, try to favor solid, durable models with an excellent warranty. If you turn it on only when you really feel the need, it is likely that a non-reinforced plastic model will do the trick.
As for the context of use, there are two main uses: at home, or in the professional world. If you need to use your window fan in your office or bedroom, it is imperative to opt for a quiet model. In your other areas of your home, this remains important but less so.
It is also important to ensure that the chosen product meets world-class electrical standards. A fan that meets this standard will have either a UL, ETL, or OSHA certification. Some even have more than one of these.
Some models are equipped with additional safety devices, such as fuse plugs: this is well worth considering.
For speed, the vast majority of models offer three: low, medium, or high. Some go further. More speeds do not necessarily mean increased power, but simply more precision. This is great to look out for.
Additionally, check out for a remote control. However, if your unit has an autoregulatory thermostat, then you are unlikely to need a remote. If it does not, then you will need the remote to make easy adjustments as required.
If it does not have either, then adjusting settings will require you going back and forth several times for constant adjustment, which is a bit of a waste of time.
Easy Maintenance And Assembly
To keep your fan as long as possible, it is often necessary to carry out the minimum of maintenance and cleaning. Hence, make sure your window fan is easy to disassemble.
On the other hand, a unit that comes pre-assembled in the pack will take less time to set up and should likewise be favored.
Weight And Dimensions
Check to see that your fan will fit the window type you have and its dimensions. Side to side differences are usually not important as there are, most often, side extenders provided. Whatever the case though, still check to be double sure that your preferred unit is an exact fit.
Another aspect to consider is the type of installation. If your preferred unit will not permit you to close your window behind it, then go for a waterproof model. That way, you can be certain that rain will not damage your window fan with your window open.
Finally, though a rare option, if you want a mobile window fan, go for one that has an integrated handle and standing legs.
The fan should be as lightweight as possible. That way, you can easily install it by yourself.
You should also decide if you want a single blade or a double blade model. If the double blade model is your preferred option, then one with same-time variable airflow should be considered. This keeps your room both ventilated and with fresh air at all times.
Finally, the last point to take into account is the aesthetics. It may sound like an accessory, but if you put an object in your living room or bedroom that you do not like, you will quickly get bored and will want to change it.
So, What’s The Best Window Fan?
