How to fundamentally solve the problem of HEPA filter replacement?

How often should the clean room high-efficiency filter be replaced? With the rapid development of the national economy and scientific research, the application of clean rooms is becoming more and more extensive, and as a key component to maintain cleanliness, the quality of clean room high-efficiency filters is particularly important. Together with the primary efficiency filter and the medium efficiency bag filter, it constitutes a three-stage filtration system in the clean room. At present, production-oriented enterprises with purification workshops generally pay more attention to filters; after all, this is directly related to the quality of the products they produce. So, how often should the clean room high-efficiency filter be replaced? How to fundamentally solve the problem 2

 

How often should clean room high-efficiency filter be replaced?

 

Method 1: Step by step

 

Today’s clean rooms have been widely used in electronics, aerospace, machinery, chemicals, pharmaceuticals, food, medical, bioengineering. If you want to ask questions that are of concern to all walks of life, it is inevitable: How long does a clean room high-efficiency filter last? Replace once?

 

Air filters are industrial consumables. If you simply follow the steps, the primary filter should be replaced every 3 months, the medium filter should be replaced at about 6, and the high-efficiency filter should be replaced every year. The cost of product replacement is still relatively large.

Method 2: “curve to save the country”

 

Different people have different answers to the question of how often to replace a clean room HEPA filter. Some people follow the steps to replace the clean room high-efficiency filter regularly, and some people start from the maintenance and replacement of the primary filter, and save the cost through the “curve to save the country”.

 

Because the price of the general primary filter is relatively cheap, frequent replacement can prevent too much dust accumulation, so as not to affect the service life of the later medium-efficiency filter and high-efficiency filter. At the beginning of the process of medium-efficiency filter, in order to save costs, we can ask the manufacturer to change the filter material inside for you, and the cost is much lower than the price of a new filter.

Method 3: Treat both the symptoms and the root causes

 

The role of clean room high-efficiency filters is becoming more and more prominent in today’s society. How often to replace clean room high-efficiency filters and how to fundamentally solve the problem has become a concern of many manufacturers. Compared with the regular replacement step by step and the rescue of the “curve to save the country”, it is a good strategy to choose a better high-efficiency filter to do it directly from the source.

 

If you want to treat both the symptoms and the root causes, it is best to go straight to the root cause. The ultra-fine HV fiber filter material is better. A good filter material can effectively improve the service life of the high-efficiency filter in the clean room and increase the dust holding capacity. The filter material that is too poor may be cheap at the time of purchase, but it needs to be replaced frequently. It’s not worth it after all.
