I heard that the next king bought an air purifier. When I saw someone, the air in the house was fresher than the park. I ran to his home in the morning and felt it. It was really good. I thought I would get one. This online shopping is really convenient. I sent it to the door in the morning of the order, and I thought it would be more comfortable to go to sleep.
It’s strange to say that things didn’t start as expected. The air index is getting better, but the air purifier's air outlet is so loud that people can't sleep at all. Feeling still important to sleep, so stop the purifier first.
The next morning, I ran the old king's house again. This time I was humbly asking for advice. It turns out that this air purifier is really a bit exquisite, especially at home, this noise problem is important to examine. Especially when sleeping, the environment is quieter, and the noise control is more obvious.
Pick a quiet air purifier: look at the quality of the fan first
At present, there are two main types of fans used in air purifiers on the market: axial fans and centrifugal fans. The axial flow fan is the same fan with the same axial direction as the air blade. For example, the electric fan that we usually see, its air volume and wind pressure are relatively small, and the noise generated is large. The centrifugal fan can not only overcome the huge resistance caused by the high-efficiency particulate filter + activated carbon, but also can output a considerable amount of clean air, and the noise generated is low.
Pick a quiet air purifier: Is the air duct design reasonable?
At present, the air duct design of air purifiers on the market is mainly divided into box structure, tower structure, column structure and double inlet structure. Let's take a look at these four categories of wind tunnel design.
Box-type structure: Most of them adopt the “in-and-out-out†air intake mode, which not only has a small amount of ventilation, but also uneven air inlet and outlet, and it is easy to raise dust. Even if its CADR exceeds 300-500m3/h, it will cause noise and influence. The quality of home life.
Tower structure: Most of them use a thick single filter, so the body can fill about 2KG of activated carbon. However, it consumes a lot of electricity and is not environmentally friendly.
Column structure: The bottom of the product is generally cylindrical, which not only increases the area of ​​the filter, but also extends the life of the filter. However, due to the narrow air duct, it is easy to generate unacceptable noise when the air intake enters the air.
Double inlet structure: Most of the structure design of “double side air inlet and upper air outlet†not only accelerates air circulation, reduces purification dead angle, but also creates CADR value—700m3/h. In addition, it can give you a comfortable and comfortable sleeping environment while purifying the air.
Pick a quiet air purifier: pay attention to the volume of the sleep mode
The probability of physical and mental illness caused by noise is still quite large, and the treatment is difficult, which brings great trouble to people's daily life and work. So when we choose a purifier, we need to pay attention to whether the decibel of the sleep mode exceeds the decibel at the standard rest. In general, the purifier sleep mode running below 30 decibels allows users to have a good sleep experience.
