Filter function of the first stage of the water purifier

The first filter is known as the PP filter. The most important task of this filter is to remove mud and sand from the water.
PP fiber filter
Polypropylene is one of the most compact and high quality filters for home purification.
The advantages of the first stage home purifier filter are its cheapness as well as its efficiency in the RO home purifier.
At first glance, the appearance of this filter may seem simple, but it is able to absorb large particles of water with high accuracy so that these particles are not transferred to the next stages of treatment,
One of the worst harms of salts in water is that it accumulates in the kidneys and causes kidney stones.
One of the important features of this filter is that in the first stage of purification, all the coarse salts in the water are absorbed, and this increases the life of other filters and also improves the purification performance.
Therefore, it is very obvious that the number of replacements of this filter should be more than the number of replacements of filters in the next stages of the water purifier.
Time to change the filter of the first stage of desalination
Types of water filters need different replacement times according to their efficiency and quality, but the quality of available water can also have a significant impact on this period.
Water purifiers are produced in one stage up to 6 stages and even 7 and 8 stages; But it should be noted that the 6-stage home water purifier is one of the best types of devices that has 6 different filtration stages.
These products are known as the best purifiers in the world. Of course, they have different prices depending on the brand you bought.


The first filter is the 5 micron PP propylene filter. When the color changes, we can see the end of the life of this filter.
In fact, the process of impregnation of impurities occurs in this filter. If the white of the filter changes to a very dark brown, it means that it is time to replace it.
Replacement time can vary depending on water quality. Usually a period of 4 to 6 months is considered a good time.
Usually 4 to 6 months is the best time to replace the first stage filter of a water purifier.
Note that this filter is housed inside a glass enclosure called a stage 1 housing or glass housing.
