Which brand of heating and cooling fan is good?

It depends on what you need. Of course, these brands of Gree and Midea are relatively large, but I think it is better to use air conditioning to buy large ones. I suggest you buy Murphy brand small household heating and cooling fans. There are two modes of cold and warm, and there are three gears to adjust the wind speed, which can be used in all seasons.

This is what I use now. I often use it at work, reading books and playing with my mobile phone. It is not loud and will not affect others. Warm air and cold air are very strong, and they don't do it for long. Hot air is the kind of warm and humid feeling, and cool air is the kind of cool air, which is very comfortable and can be blown directly at people.

Its water tank has 400ml and can last for 8 hours. The water tank is detachable. When the water is used up, it can be directly disassembled and filled, and can be recycled. Wide-angle air supply around can blow a large area, which is absolutely possible for one person.
