How to choose the right air filter

According to the specific circumstances, choose the appropriate air filter reasonably. The selection principle is as follows:

1. According to the clean and clean standards required by the indoors, determine the efficiency of the air filter at the end of the Zui, and reasonably select the combined number of air filters and the efficiency of each level. If the indoor requirements are generally cleaned, the primary effect filter can be used; if the indoor requirement is medium purification, the primary effect and medium effect two-stage filter should be used; if the indoor requires ultra-clean purification, the initial effect, medium effect and third level should be adopted. Purify and filter, and should properly and properly match the efficiency of each level of filter. If the efficiency of the adjacent two-stage filter is too different, the former filter will not protect the latter filter.

2. Correctly determine the dust content and dust particle characteristics of the outdoor air. Since the filter is filtered and purified and sent into the room, the dust content of the outdoor air is an important data. Especially in multi-stage purification and filtration treatment, when selecting the pre-filter, it is necessary to consider the factors such as the use environment, spare parts cost, operation energy consumption, maintenance and supply.

3. Correctly determine the filter characteristics. The characteristics of the filter are mainly filtration efficiency, resistance, penetration rate, dust holding capacity, filtration wind speed and treatment air volume. When conditions permit, filters should be selected as far as possible, with low resistance, large dust holding capacity, moderate filtering wind speed, large air volume, easy installation and installation, and low price. This is an economic analysis that takes into account the one-time investment and secondary investment and energy efficiency ratio when selecting air filters.

4. Analyze the nature of dusty gases. The nature of the dust-containing gas associated with the selection of the air filter is mainly the temperature, humidity, acid and alkali, and the amount of organic solvent. Because some filters are allowed to be used at high temperatures, some filters can only work at normal temperature and humidity, and the amount of acid and alkali and organic solvent containing dust gas have an impact on the performance efficiency of the air filter.
