Is this a polyphosphate filter


That is a question for you to ask. But do you know what is inside your filter? I don’t expect you to cut open your brand new filter to find out but remember that there are different filters for different reasons. So make sure you do your homework before you put one in to make sure it is filtering what you want, ie: taste, rust/grit, chlorine… These filters were removed from a friend’s house today. The one on the left is from her insta-hot and the other is from her refrigerator inline in her copper line.

  1. Generally, polyphosphate feeders are effective in low volume, cold water applications. The polyphosphate dissolves into the water and coats the iron, calcium and magnesium in it, making it impossible for these agents to precipitate out of the water and create the problems associated with hard water.

    Polyphosphate crystals are placed within a housing and as water flows through it, the crystals dissolve.

    Polyphosphate is also available in a more traditional filter. These filters are effective for relatively small quantities of water, and are commonly used in low volume applications such as refrigerator ice makers, etc.

    Unfortunately, polyphosphate-type systems are only effective in cold water, low volume applications. It should also be noted that phosphates are a preferred "food" for bacteria - so if bacterial contamination is a concern (in private, non-chlorinated water supplies, for example) you may want to reconsider using a polyphosphate system.
