Air filter is a "mask", it should be useful, reliable, pleasing to the eye, and convenient. What occasions what kind, what efficiency of filter configuration, which is developed through many years practice. Lesson make filter makers and designers continuously improve products and engineering design, but often people only talk about experience not to mention the lesson.
Our air conditioning engineers have had their own experience, introduce the project and the actual lesson and constantly hit our past experiences. Especially, lessons tell people, low efficiency of the filter caused tuyere black stains, faded walls, air conditioning system of formation, the cost of the deal with these problems is amazing, have had such lessons will improve the efficiency of the filter in the new design specifications, while others only consider to choose the filter from the Angle of health.
In order to put an end to the tuyere black stains, maintain indoor decorate do not fade, keep clean air conditioning system and air supply pipe, the comfort air conditioning system in the city had better choose F '7 efficiency specifications (colorimetric method 85%, China's specifications "high school") of the filter.If only considering the standard provisions of the state public pm10 concentration limits (0.15 mg/m3, or 0 or less or less. ~ me, / m3), USES the G3 filter is enough.You can view the website in the < various occasions in the choice of air filter > view some occasions filter configuration, the configuration is now more popular configuration, decades of teaching and the experience prompted by the configuration choice filter
