What are main filters or pre-filters?

What are main filters (or pre-filters) If your apartment already has a water purification system, but you would like to protect plumbing with household appliances from dirt, then we recommend installing a main filter. This is a fairly simple system, but it can extend the life of both the water filter in the apartment and the dishwasher and washing machine.

Main cleaning prolongs the life of single-lever faucets. The main filter consists of a flask in which several grids are installed or a replaceable cartridge is placed. Their feature is the ability to use special cartridges for cleaning from various types of impurities. For example, removal of chlorine or iron particles, water softening.

A pre-filter, is installed in the line at the inlet to the home water supply system. Hence the second name of pre-filters is main filters. Most often they purify water from the city water supply or are part of the water treatment system in the cottage.

Advantages and disadvantages of using such a filter for cleaning

Advantages of main filters:

- High degree of purification

- Water can be used for drinking by humans and domestic animals, domestic needs;

- Removal of chlorine - reduces the risk of developing allergies, irritation of the respiratory tract;

- Simplicity of a design;

- Small linear dimensions of the device;

- Wide temperature range

- but for hot water lines it is advisable to use special filters, since the device must withstand significant loads;

- For column-type devices

- the presence of an automated control system;

- Low cost of equipment and its operation.

The disadvantages of main filters depend on their design. Mesh devices remove only coarse impurities; their removal is required for cleaning. Cartridge-type devices require regular replacement of the filler, interruption of work to install a new filter system. Columnar - the presence of volumetric flasks, filter elements.

Service Rules

The main rule when servicing main filters, in addition to replacing the cartridge, is the obligatory rinsing of the flask, cleaning and disinfection. This helps to eliminate the risk of growth of pathogenic flora.

Conclusion

The main prefilter is a vital necessity, since sometimes tens of kilometers of pipes are separated from the water treatment system and the consumer. Somewhere there are areas of corrosion, small cracks through which mechanical impurities pass, and all this will fall into the water. The prefilter is an inexpensive and simplest device for removing impurities. Sometimes it is quite enough, and more expensive water purification systems are not required.
