The More Filters, The Better The Filtering Effect?

I believe that when many friends are considering choosing a fresh air system, they will more or less see some manufacturers like show equipment, claiming how many layers of filters they are equipped with, which can filter and purify PM2.5, formaldehyde and other pollutants. At first glance, it does feel that this product has a very powerful purification ability. But careful friends will think about such a question: the more layers of filters in the fresh air system, the better the filtering effect?

Most people think that the more layers of filters in the fresh air system, the better the filtering effect. This concept is instilled by the propaganda of highly competitive manufacturers. In order to highlight the “advantage” of their own products, some manufacturers put many layers of filters in the product, or list several “technologies” used, some are 6-layer filters, and many more even 8 layers Strainer. But many of these “filtering techniques” are really eye-catching gimmicks. 
  
Although it is said that if we can buy more things at the same price, it must be a very proud thing for all of us, but in fact, for the number of filter layers of the fresh air system, it is not that the more layers, the better. All right. And if there are too many filters, there are also many hidden dangers.  

For example, the more layers of filters, the greater the wind resistance, which will affect the air volume of the fresh air system. In order to achieve the designed air volume, it is necessary to increase the speed or power of the fan, which is followed by an increase in energy consumption and an increase in noise. If the energy consumption and noise problems are not well controlled, it will be very unfavorable to the cost and experience of everyone’s later use.

The filtration and purification capacity of the fresh air system is not directly related to the number of filters. Under normal circumstances, it is enough for the fresh air system to have a primary filter, a medium-efficiency filter and a high-efficiency filter. The outside air must first filter medium and large particles and other pollutants through the primary filter and medium-efficiency filter; then through the high-efficiency filter to filter PM2.5 fine particles; finally, through the activated carbon filter to absorb external chemical odors, etc. harmful gas. If the fresh air system lacks the primary filter, its high-efficiency filter will soon be blocked and needs to be replaced. If the level of the high-efficiency filter is lower than the HEPA H13 level, then its filtering and purification capacity will be greatly reduced, and it will not be able to effectively filter PM2.5. The activated carbon filter can deodorize, deodorize and purify the environment under a certain air volume, and has a good purification effect.  
The more layers of the filter screen, the more power the fresh air system needs, and the replacement of the filter screen also costs a certain amount of money, which is a waste. An important reason for choosing a fresh air system is nothing more than to breathe fresh and clean air, so everyone must think rationally when choosing a fresh air system.

According to the positioning of the product itself, the performance of the motor and the product structure, the KCVENTS fresh air system reasonably selects the appropriate filter combination for the user.
