Below are some of the most frequently asked questions we receive from customers regarding our Whole-House Systems and Drinking Water Systems.


  • What is a water softener?

    A water softener is a water treatment system that uses ion exchange technology to replace calcium ions with sodium ions, effectively removing the minerals that cause hard water. Some water softeners will combine activated carbon with the resin beads to work in tandem to remove water hardness and chlorine from city water. Most water softeners are connected as a point-of-entry system, in-line with the home water plumbing by the main shut-off valve, providing soft water throughout the entire residence.
  • What is the difference between the systems?

    Puronics® manufactures salt water softeners, no-salt water filtration systems and RO systems.

    The primary difference between the Defender™, Hydronex® and Terminator® is the tank construction and material. The Terminator® has an extra layer of filter media.

    No-salt water filtration systems filter the water, but they do not soften it. The Goodspring™ BWS and Goodspring™ BPS both include ScaleMax™, which reduces scale build-up. They differ in tank material.

    In the RO systems Micromax™ 7000, has the sleekest design and easily fits under a kitchen sink. The Micromax™ 6500 has an additional pre-filter for sediment. The Pur-Alkaline filter is designed to be used along with a reverse osmosis system to add back minerals and increase the pH of the water.

  • What is the difference between the type B and C systems?

    They have different amounts and types of carbon, and one needs maintenance before the other.

    The type B has 3 lbs of patented Bacteriostatic carbon that has SilverShield® Protection (technology derived from NASA, EPA certified) it keeps bacteria from growing in the tank media. The carbon in it has a lifespan of 117,000 gallons before it has to be replaced. The IGen controller notifies you when that time has come.

    The Type C has 15 lbs of Chlorostatic® catalytic carbon; it is certified by the WQA to remove the chlorine and chloramine (ammonia and chlorine) for 2 million gallons before it needs to be replaced. Mostly used for well water system.

  • How long does the filter media last?

    SilverShield® HYgene® lasts for 112,500 gallons of water. For Clarius™ and Goodspring™ systems, the Purifex® media should be replaced at the same time as the SilverShield® HYgene®. For Goodspring™ 10” systems with ScaleMax™, the ScaleMax™ media should be replaced every 5 years or every 375,000 gallons of water. For Goodspring™ 13” systems with ScaleMax™, the ScaleMax™ media should be replaced every 6 years or every 500,000 gallons of water. Our smart iGen® series systems inform you when it is time to change the filter media by saying “Call for service” on the display. Those systems are measuring the water that gets filtered by the system. For our prior generation of systems, you will need to estimate how often the maintenance needs to be done based on an estimate of your water usage.

    Drinking Water System

    The pre- and post-filters last one year. The membrane lasts 3-5 years.

  • What kind of salt should I be using?

    Any brand of extra coarse water softener salt or pellet type water softener salt.
  • How often do I need to add salt to the brine tank?

    Check the brine tank every month to month and a half. Add one bag of salt as needed to keep the tank at least half full.
  • What type of warranty do they have?

    You have a limited lifetime warranty from Puronics for both units. The good thing about Puronics water softeners is that they are high-quality water softeners. Puronics water softeners are made in the USA, and they use certified parts and components that are also certified by the WQA and EPA. Because of this, you can trust that they will work as advertised.
  • What maintenance is required?

    For our systems with bacteriostatic carbon filter media, SilverShield® HYgene®, the carbon must be replaced every 112,500 gallons of water used, which for a typical family of 4 is about 12-18 months.

    Our smart iGen® series measures the amount of water that is filtered and informs you when it is time to change the filter media by saying “Call for service” on the display.

    Our systems that use salt for back flushing need to have the salt replaced periodically. Keep the salt at least half full in the salt tank.

    Drinking Water System

    In order to continue to operate as expected, the filters need to be replaced. By replacing your filters regularly, you ensure that you will continue to have high-quality water.
