The main source of problems is the human factor (error with the technical characteristics of the filter, incorrect installation, errors when replacing the filter, buying forgery, delayed replacement). There are few exceptions; you can get a defected filter that's why you need to check the condition of the filter from time to time and replace it with the slightest suspicion of a malfunction.

Signs of clogged filter:
