It is easy to judge from the appearance, and most users can see it directly. Generally, activated carbon filters can be used for two or three years, and well-maintained equipment can be used for four to five years. Maintenance is the key. Correct maintenance can give full play to the greater use value of the equipment.
There are several good ways to judge whether the activated carbon filter should be replaced:
First, observe. Observe whether there are any changes on the outside of the activated carbon filter. If the filter has been used for a long time, its appearance will be gray or black. At this time, the filter should be replaced with a new one.
Second, whether you are angry. The activated carbon filter has no problems and will not leak, but if there is a leak, it must be due to a long time of use, some internal parts of the equipment malfunction, aging, etc., so it is necessary to replace the new equipment in time.
Third, maintenance. Maintenance is very important. If there is a lot of dust in the activated carbon filter and the original appearance cannot be restored after many cleanings, it means that the device has been used for a long time and a new device needs to be replaced.
