Are there different types of fans?
Yes, table fans are generally the cheapest and have the lowest power consumption, but they are usually best used at close range. (There are also handheld fans that come in handy on sweltering subway trains, but their output is very low, so I won't review them here.)
Tower fans are ideal for bedrooms and living rooms because they don't take up much floor space and have a wider range than tabletop fans.
Pedestal fans consist of a circular blade unit at the top of a stand and tend to be more powerful than tower fans. Some, like his Duux above, can be converted between tabletop and pedestal fans by removing the stand.
Finally, floor fans tend to be large and can cool large rooms. You may see them in gyms and conference centers.
There are also air coolers that use water evaporation to cool the air slightly, but we'll discuss those in another feature.
What is the quietest fan for sleeping?
When purchasing a fan for your bedroom, choose a model with a quieter sleep mode or one with a noise level of around 50-55db. For comparison, background noise in an office equates to about 50db, and a refrigerator or laptop emits about 35db.
The type of fan motor affects the level of noise the fan makes. “Fans are equipped with AC (alternating current) motors or DC (direct current) motors. DC motors are brushless, so they are quieter, more energy efficient, and better,” says a specialist fan retailer. There is an air conditioner in his center, Nick Kandra explains. Air conditioner and dehumidifier.
Is a fan without blades better?
It's hard to quantify whether bladeless fans are better, but they are definitely safer. As we've already mentioned several times, bladeless designs are the type to buy if you have kids or pets, and they're easy to clean, quiet, and energy efficient. It works by drawing air in through a slit in the base and pushing it back through the ring.
The downside to bladeless fans is that they tend to be much more expensive due to the technology. If you have the budget, a bladeless fan is recommended, but a regular blade fan will also suffice.
