Actually not. First of all, we need to understand what the role of the filter is, mainly helps us purify the pollutants in the air. Secondly, do our indoor pollution really need to go through so many filtrations to achieve the best purification effect? ??Filter?The more nets, the increase in energy consumption and the increase of noise. If the problem of this energy consumption and noise is not controlled, it is also very unfavorable to the cost and experience of everyones later use.Therefore, how much the filter is selected according to the air quality of everyones city, and try to choose a new new with the HEPA13 filter
Generally speaking, the filter of the fresh air system is divided into three levels: early -effect filter, medium -efficiency filter, and high -efficiency filter (HEPA filter).Common standards can be divided into G, F, G. From G1 to H13, the higher the level, the better the filtering effect, but the greater the corresponding wind resistThe higher the request.
Effect filter: filter dust particles with 5 microns.Such as the particles visible to the naked eye, such as hair, pollen, catkins, etc., improve the life of high -efficiency filters and reduce wind resistance.
Medium -Effect filter: cooperate with the initial effect filtering to further intercept larger particles.
High -efficiency filter: Catal the dust of particles below 0.5 microns and various suspension, which can not only remove smoke and dust, but also isolate bacterial pollutants.
In the fresh air system, the initial results, medium -effect, and efficient filters are generally not used separately, but are used in both cooperation.There are generally many indoor PM2.5 and PM0.3, and 99%of pollutants can be filtered in the air with initial effects and efficiency. Generally, the filter is recommended to replace it every 2-4 months.Different air quality will also cause differences in the cycle consumption of filters. For example, in areas with severe air pollution, the replacement cycle is required accordingly; areas with good air quality can be appropriately extended the replacement cycle.
What should I do if I forget to replace the filter?
Our new wall -mounted fans have a filter element replacement prompt function. As long as the cumulative operation of 4,000 hours, the panel will always flash, reminding you to change the filter ~ If you have not handled it in 48 hours, the bee tweee will call the police. The air at home is air.If you do n’t need to replace it, you can also close it manually!Changing the fresh air filter in time can better protect the air in the room clean.
