Polido installation

The difference between Polido and regular polyphosphate filters

The difference between Polido and regular polyphosphate filters is that the water may become toxic if left unused for long periods of time with regular polyphosphate filters, whereas the water output from the Polido filter is always safe and drinkable. In regular polyphosphate filters, due to the filter’s inability to inject and dissolve polyphosphate to a lesser or greater extent in different flow rates, these filters will not have proper control over lime scale buildup.

Installer Benefits

  • Requires a maximum installation space of 12 centimeters for the filter installation.
  • Can be installed quickly without the need for Teflon tape.
  • The polyphosphate tablet can be replaced quickly without interrupting the water flow.
  • Can be installed vertically or horizontally and even connected directly to the wall-mounted package unit.
  • The transparent body of the filter tank allows for easy monitoring of the polyphosphate tablet replacement time.
  • The filter body is easily detached from the tank by hand without the use of any tools.
  • Equipped with all necessary connections and washers for installation.
  • Comes with a 5-year unconditional warranty, even in the case of breakage or improper use.
  • Has a unique tracking code for complete product tracking.

Consumer Benefits:


  • Non-toxic water thanks to the venturi mechanism inside the filter
  • 100% control over preventing the formation of lime scale in various water flows
  • Simple replacement of the tablet without the need for any technical knowledge or special tools
  • Tablet replacement without the need to cut off the incoming water flow
  • Increased lifespan of the package’s heat exchanger
  • Elimination of current deposits in the path
