Why your filter cartridge has a short service time?

If your filter cartridge has a short life, it would result that you should change your filter cartridge quite often, and the downtime and maintenance costs increase significantly.

As a manager of the plant, you would not like to see this thing happen all the time. But what’s on earth the reason for this problem? Here, we summarize some of the factors that lead to the short service life of filter cartridges.

Why your filter cartridge has a short service time
  • Unstable raw water quality;
  • unqualified-filtration process, former carton media extractable;
  • Microbial crazily grow in summer;
  • Ultra-filtration membrane damaged;
  • Overloaded flow rate capacity;
  • Badcartridge filter quality;


We have analysed the samples that have short service time in actual usage. And from ponit1 to point5 are all objective factors, which have no relation to the filter cartridge itself. If all objective factors were excluded, the quality of the filter cartridge can be the only reason to blame.

We would like to recommend our high-flow filter cartridges to you, they have high efficiency with a large filtration surface and high dirt-holding capacity, of course, longer service time.

What normally will happen to a poor-quality cartridge filter in daily operation and maintenance?

poor-quality cartridge filter
  • Breakage
  • Deformation
  • Leakage
  • Small Effective Filtration Area

Why do they happen?

Breakage normally happens to the cartridge filter with the out-inside flow direction. It is caused by the weak inner core and poor filter unit connection welding.

Deformation normally happens to cartridge filters with inside-out flow direction structure. It is caused by soft outer netting.

Leakage is caused by poor thermal welding of membrane side seam and membrane with end cap, especially in those factories automation production cannot be promised.

Not enough effective filtration area is caused by unreasonable membrane structure and pleat heights.


If we take the RO membrane as the heart of the body, the exquisite and expensive part of a water filtration system, then the cartridge filter is the keeper to make sure blood is pure. That is why a cartridge filter is an important and essential guard to the whole system.

When your cartridge filter only plays for a few days, that would be a catastrophe for your whole system. If you want to change this situation, all you need to do is send us your used filter cartridge for us to analyze. We will find out why and offer you a satisfied solution.
