Water filters

DFA-A disc filter with automatic backwash – If you do not want to bother with the cleaning of your filter, we recommend this model. Cleaning is performed automatically in a few seconds. If you have purchased an automatic water softener, you can complete your water engineering with an automatic water filter.

In case of residental water filters, the three most important design aspects are: COMFORT, QUALITY, DURABILITY.

  • QUALITY: Many water filter filter cartridges on the market are small sized, usually with 100 µm filtration fineness. The filter is built from filter discs, that provides 50 micron filtration and, thanks to its large filtration surface, the pressure drop is small.
  • DURABILITY: Due to the long service life, the filter discs need to be replaced rarely.
  • Other benefits:
    • Built-in check valve prevents backflow of liquid.
    • A shut-off function is activated by turning the hand lever, eliminating the need to install ball valves before and after the filter.
    • The threaded connection of the pre-filter can be rotated 360 degrees, allowing it to be installed in different positions.
    • Its display has a backlight function so it can be used in dark places.

Another argument in favour of the automatic filter disc water filter and SAFETY. The water filter has a water leakage detection function. What does this function mean? The water filter monitors the amount of water flowing through it and the instantaneous flow rate, which it uses to detect any pipe bursts or leaks in the water network. If necessary, the automatic water filter will intervene to prevent pipe bursts and water damage in households.

Another reason to choose our automatic disc water filter is SAFETY. The filter has a water guard function. What does the water guard function mean? The water filter monitors the actual amount of water flow and checks for possible pipe breaks and water leaks in the water supply.  If necessary, the automatic water filter intervenes to prevent pipe fracture and other damage in your household.

The simplest option is the clear filters; usually available is 5” and 10” size. These are available with disposable and washable filter cartridges. It is IMPORTANT to know that the disposable filter cartridges must be replaced annually, or in case of a 0,5 bar pressure drop, immediately. This is important because the disposable filter cartridges allow some of the particles to pass through in concentrated form after clogging, which is not good for the faucet or the water softener and any other equipment that uses water. The passage of contaminants occurs when a pressure drop of 0,5 bar is reached. Only choose this solution if a pressure gauge is installed before and after the filter and the condition of the filter element will be checked on a weekly basis.

Usually a 5” and 10” sized washable filter cartridges are made with thin plastic filter surface. If the filter surface of thin plastic is damaged (which is almost invisible to the naked eye), the filter will no longer filter anything. According to our experience, water softener (and/or faucet) failures are most common in systems with these types of filters. We do not recommend using these kind of filter cartridges in households, because we do not consider the thin plastic filter surface to be reliable in long-term operation.

As professionals we recommend such water filter for protecting your household that meets the following requirements:

  • It is important that the filter cartridge is made by a material that provides reliable mechanical filtration. The best solution is a stainless steel filter cartridge or a disk filter.
  • Fine sand (63-100 µm) occurring in the water supply should be filtered to protect household assemblies and equipments. Previously, the expected filtration fineness of filter cartridges was between 80 and 100 microns. Today the development of technology requires stricter filtration below 50 microns, and the current level of technological development provides the possibility to comply with stricter limits at an affordable price. The warranty condition of the BlueSoft and RainWater softeners is a 50 micron pre-filter.
  • It should be easy to clean. If it is difficult or takes a long time to clean, and the water pressure need to be drained, the user tends to miss cleaning the filter.
