With the arrival of summer, many families will choose to buy fans to share the pressure of indoor air conditioning, but the types of fans on the market are endless, making people not know how to choose for a while. But among the many fans, as well as several best not to buy, not only noisy, but also uncomfortable to use.
1, do not buy AC fan
At present, the fans on the market are mainly divided into 2 types of DC brushless motors and AC motors, of which the DC brushless motor fan has small resistance, low noise, low energy consumption, and flexible gear adjustment, while the AC fan is just the opposite.
2, do not buy fixed frequency fans
Fixed frequency fans and air conditioners have the same principle, and fixed frequency fans have relatively high power consumption. The inverter fan not only has low energy consumption, but also has low friction loss, low noise during operation, and is more comfortable than the fixed frequency fan, which is the first choice for many people.
3, do not buy noisy fans
At present, many fans on the market in the process of operation, due to the fast speed of the fan, will emit a humming sound, thereby affecting people's rest, so it is recommended that you buy those fans with relatively low noise.
4. Do not buy a non-removable fan
When we buy fans, it is best not to buy those non-removable fans, because after the fans are used for a long time, it is easy to appear a lot of dust, so the wind blown out is also dirty, so we better choose a fan that can be disassembled, so it is convenient, and it can always keep the fan clean, does not affect the environment, and the family is more at ease.
5. Do not buy a fan with a short air supply distance
When we buy a fan, it is best not to buy a fan with a close air supply distance, because this fan is only close to the cooler, and the wind from the far wind is weak, and there is no feeling. Therefore, we try to choose a fan with a slightly farther air supply distance, which is more worry-free to use in summer.
