The core of the fresh air system must be the fresh air unit, and the most important components in the unit are the heat exchange core, the filter mesh and the motor.
Among them, most of the motors are brushless motors, which do not require maintenance.
How long is the maintenance cycle of mesh?
Regarding the cycle, it is actually determined according to the usage habits of each user and the climatic environment of each region. Generally speaking, the lifespan of medium and high-efficiency filters in areas with severe haze is no more than 3 months at most. While in areas with relatively good air environment, it can be replaced every 6-12 months. Of course, it does not mean that all dirty filters need to be replaced. If there is only a lot of dust, you can continue to use them after cleaning. Therefore, it is recommended to check them every two weeks, and judge whether to clean or replace them according to the actual situation.
How to maintain the filter?
Many types of equipment are composed of multi-layer filters. The nylon filter can be washed with water. The routine maintenance of the medium and high-efficiency filters is to use a vacuum cleaner to remove the floating ash on the surface. If it is very dirty, the medium and high-efficiency filters can only be replaced for a good filtering effect.
What happens if the filter is not maintained in time?
If the filter is not maintained and replaced in time, firstly, PM2.5 cannot be well filtered, and the indoor PM2.5 concentration will increase. Secondly, the dirtier the filter, the higher the probability of breeding bacteria and germs, which will lead to secondary indoor pollution and affect Health. In the end, the dirtier the filter, the greater the resistance, which will increase the power consumption of the motor, or even more seriously, the motor will be burned and then affect the normal use of the fresh air system.
