With the increasing air pollution problem in recent years, thousands of FFU air purifiers have entered the civilian purifier market at low prices and high-efficiency filtration effects, squeezing out some of the market share of specialized civilian purifiers. Entering ordinary households, the function of FFU has been increased from industrial use to civilian use. The FFU filter removes the haze to people in the haze area and also brings secondary pollution. For most FFU purifiers currently on the market, we should examine the advantages and disadvantages of this product from a more professional perspective. Let’s take a closer look at the FFU purifiers currently on the market.

FFU advantages:

1. Maximum air volume: 1000-1200 cubic meters of household air volume is relatively large, Yuanda ta1000 air volume per hour is 1000 cubic meters, the price is 8K+ followed by Amway’s maximum air volume of more than 500 cubic meters, the price is amazing, and then IQAIR’s maximum air volume is 400 cubic meters and Taobao price is 8K+

2. Filtration efficiency: 99.97%@0.3um, 100%@0.5um, IQAIR 100%@0.5um in the field of home appliances

3. Market price : FFU package price is about 1,000 yuan, and the price of civilian purifiers is several times, even some foreign brands are more than 10,000 yuan.

FFU disadvantages:

1. FFU’s core component motor

The motor is the heart of any device and a decisive component. What kind of FFU air purification artifact is suitable for home use? Just look at the ability of FFU air purifier to remove smog compared to purifiers of more than 10,000 yuan. There is no problem at all. The filtering effect is leveraged, but FFU is still an industrial product after all, even if it is modified into There are still many problems with civilian purifiers. The primary problem is that 80% of manufacturers selling FFU air purifiers on the market do not distinguish between industrial use and civilian use. The FFU fans used in industry are basically equipped with heat dissipation holes. Because high temperature is generated inside the fan when the fan is running at high speed, in order to cool the fan, it is necessary to use heat dissipation holes. The fans in the civil field are all sealed low-temperature fans. After running for one or two hours, the surface temperature of the fan is basically not higher than 50 degrees, and it will not be hot to the touch. The lower the temperature of the fan, the better, but the cost will increase accordingly.

2. FFU filter parts high efficiency filter

One of the main problems of FFU purifiers now is the odor problem caused by industrial FFU modified products. The source of odor is mainly high efficiency filter element. The source of the smell of glass fiber filter paper: the glass fiber cotton needs to be acid washed before it can be fully dispersed. After washing with water, spray water-soluble glue and pulp composite. The water-soluble glue is acidic glue and will reduce its nature and release sour gas when the humidity is high. Washing will cause a large amount of residual acidic substances to release acidic gas for a long time. Industrial clean rooms such as operating rooms and electronic workshops will be delivered for use after several months of air-blowing operation and debugging, basically 12-24 hours of operation, with constant temperature and humidity system, 5-level filter system protection, fresh air system to compensate for fresh air, and sterilization system protection Prevent the growth of bacteria. The household purifier will humidify in winter. The humidity is too high and the indoor temperature is just suitable for the growth and reproduction of microbes and bacteria. The more microbes and bacteria multiply, the more metabolized, the greater the smell. The musty smell is also because the filter paper produced by the wet papermaking method is hydrophilic.

The above problems show the difference between civil FFU and industrial FFU. Only according to the characteristics of civil FFU purifiers, we can make FFU products that are more suitable for household use. As a professional FFU manufacturer, Nanjing Yixiou hopes that civilian FFU purifiers can be Only by making some optimizations and improvements on the basis of industrial use to use the segmented needs of the civilian market can the household FFU remain invincible, rather than a short-lived in the purifier market.
