How often is it better to replace the high-efficiency filter? Generally speaking, high efficiency filter life up to 2-3 years must be replaced. High-efficiency air filters used for a long time will have to be replaced so that most of the use of clean room production is better for the clean effect, in fact, the end of the value of high-efficiency air filters for them is not high, all together may be less than a few hours of their output, but the risk of changing high-efficiency filters and the indirect costs for them to speak of the high, which is why most customers in the purchase of high-efficiency filters are generally required to replace the installation or even during the Spring Festival replacement installation reasons. This is the reason why most of the customers who have purchased HEPA filters usually ask for replacement and installation during holidays or even during the Spring Festival.

Because the change of high-efficiency filters have to stop production, and the loss of production stoppage can only be calculated by the owner of the enterprise, this loss is certainly higher than the cost of spare parts for high-efficiency filters.

Changing HEPA filters is a very serious operation, anything in a clean room can be expensive, and destroying one of the components can cost more than the purchase of all the HEPA filters. After the change of high-efficiency filters but also by professionals to test, and sometimes to stop the air conditioning system debugging, but also after a period of trial operation, these times for the enterprise is also its long period of time.

Detection, commissioning, test run, three costs added to a piece, may not be comparable with the price of high-efficiency filters. Smart homeowners always want to extend the life of the high-efficiency filter as much as possible, not to save the high-efficiency filter that a few dollars, they want to prevent a bunch of trouble due to changing the filter and a variety of troublesome products.

The most basic way to effectively extend the life of a high efficiency filter is to keep dust out of the primary filter. Changing the primary filter is generally not required to stop production, without debugging, so experienced owners will spend their concentration and money on the primary filter and maintenance level of intermediate air filters. With regard to the 100-level and 1,000-level dust-free workshop plant, the initial filter can be selected G4, intermediate can be selected F8 filter (colorimetric 95%), so that the end of the use of high-efficiency filters, the life of the filter is generally up to 3 years.

Therefore, in foreign projects and domestic new projects, F8 medium effect air filters are the most common pre-filter medium effect section in non-average flow clean rooms.

Some places, the rules for the use of high-efficiency filters life is not out of thinking about the resistance, but other elements. If the clean room plant has hydrofluoric acid and other chemicals, and workshop air conditioning is not a full fresh air system, high-efficiency filters in the glass fiber filter paper will be corroded by the return air, in order to be safe, it is necessary to change the high-efficiency filter on a regular basis.

Some large pharmaceutical plants change their HEPA filters every year after the rainy season in order to avoid any possible mold contamination on the filters. Some biological laboratories and laboratories dealing with risky products request new HEPA filters for reliability before embarking on a new important project.
