High efficiency air conditioning filter short life ratios

The filter material area of the filter is too small or the capacity of the unit is too small;

The filtration efficiency of the prefilter is low;

The life expectancy of the filter used is too high.

For the first reason, switching to multiple filters with a large filtration area can prolong service life, which should be taken into account in the initial system design. In more projects, the user requires as much as possible to reduce the space occupied by air conditioners, or suppliers in order to achieve maximum profits, the use of the filter area is small and inexpensive filters. Engineering acceptance, the filter can meet air purification requirements, but the life of the filter is relatively short.

The filtration efficiency of the prefilter is low, you can adjust the efficiency of the prefilter, you can extend the life of the final filter. According to the test data: the end of the filter is f7, the usage of the life of the final filter of the prefilter g4 is 3 months, switch to the filter pre-f5, the life of the filter f7 can be extended to six months. In the cleanroom, the final efficiency value may not be high, but the risk of filter replacement and indirect costs will be high, since the prefilter is not required to stop production, experienced owners will focus on the prefilter.
